25mm f1.4 Leica DG Summilux http://www.personal-view.com/talks/discussion/712/25mm-f1.4-leica-dg-summilux- Fri, 19 Aug 2011 16:04:25 -0600 Mimirsan 712@/talks/discussions

http://www.ebay.com/sch/Lenses-/3323/i.html?_stpos=&_fcid=168&gbr=1&_localstpos=&_nkw=panasonic+25mm+lens&_clu=2

I sold my 20mm and gots me one of these babies a few days back (first batch in UK) for a really good price (under £400 early display copy no box or pouch but got the hood!).
Also owning a Voigtlander 25mm 0.95 & Voigt 35mm f1.4 Id thought I would share my personal thoughts in comparison.
Well to start...The lens is good....damn good.
Pros
Sharp even at F1.4 Detail and rendition of colour is beautiful.
AF is very fast and accurate on my GH2 not so fast on my GF1...but still faster than the 20mm f1.7
Very controlled image...by this I mean it has very little CA and no flares

But heres the Cons
Price...I was lucky to get this cheap but general UK retail is near £560!...that im sorry is ludicrous...It has astounding optics and yeah okay f1.4 with fast accurate AF is probably why but no!
Why? Build...Plastic! (albeit harder plastic than other Panny lenses)
The voigts FEELS expensive (heck even my Super Tak 50mm f1.4 feels more expensive) you know its crafted...but the Leica? Just off the mass produced factory line...for that price we deserve SOLID BUILD!

Lacks the ability for creativity because of its very controlled image...by this I mean its lacking character...much like the 20mm f1.7.
You can have more creative image with the Voigt.
Focus ring for MF...I just dont like it...theres no give...its just silly smooth so hard to be pinpoint accurate. The Voigt has very nice dampened focus ring and can be accurate even at f0.95

I would say if it was cheaper then get one as it is really superb...but as the price is very close to the voigt 25mm f0.95 I would say get that if you can live without the AF as it gives more stops of light and feels like you bought something that justifies the cost.
Is it better than the 20mm?....absolutely without question BUT if you have the 20mm and cant afford the Leica...dont lose sleep over it.

Anyway I leave this with a quick snapshot of my little girl taken with the Leica & GF1 (both at f1.4 in jpg right out of camera no post)...I was amazed by the detail even on a ye olde GF1 so can give you a idea of the quality.

Sony Electronics, a worldwide leader in digital imaging and the world’s largest image sensor manufacturer, has today introduced a new full-frame lens for their E-mount camera system, the Planar T* FE 50mm F1.4 ZA (model SEL50F14Z).

This 50mm prime lens features a large F1.4 maximum aperture that offers impressive contrast and outstanding resolution that are hallmarks of the ZEISS® brand. It produces these consistently strong qualities throughout the entirety of the frame – from center to corner – and at all aperture settings, even while shooting wide open at F1.4. The cutting edge optical structure includes high-precision AA (Advanced Aspherical) and ED (Extra-low Dispersion) glass elements that reduce spherical and chromatic aberration, as well as a ZEISS® T* Coating that minimizes flare and ghosting creating the classic ZEISS® clarity. Additionally, its Planar design ensures minimal distortion.

The large F1.4 maximum aperture of the FE 50mm F1.4ZA lens provides a level of brightness and speed that are advantageous for dimly lit indoor shots, night scenes, and portraits, while its 11-bladed circular aperture allows for stunning “bokeh”, or background defocus, in images. The lens also features an aperture ring with an adjustable ON/OFF switch, an AF/MF focus mode switch, and a dust and moisture resistant design¹, further increasing its functionality.

The new lens is also equipped with a ring drive SSM (Super Sonic wave Motor) system, which allows it to efficiently lock focus with speed, precision and in near silence, making it particularly useful for shooting movies.

Pricing and Availability – FE 50mm F1.4 ZA Lens

The new FE 50mm F1.4 ZA lens will ship this July for a retail price of $1,500 US and $1,950 CA. The new FE interchangeable lens will be sold at a variety of Sony authorized dealers throughout North America.

12mm F1.4 Panasonic lens http://www.personal-view.com/talks/discussion/15216/12mm-f1.4-panasonic-lens Tue, 14 Jun 2016 08:58:50 -0600 Vitaliy_Kiselev 15216@/talks/discussions image

The new 12mm wide-angle lens enables photographers to capture beautiful group, event, and nature photography. It also allows indoor shooting in low lighting and produces an impressive, natural defocusing effect with its F1.4 aperture. In addition, the LEICA DG SUMMILUX 12mm/F1.4 ASPH. boasts a rugged, splash/dust-proof design (when combined with splash and dustproof LUMIX G Mirrorless camera models) to meet the needs of a wide-range of photographic situations.

Integrating two aspherical lenses, two UED (Ultra Extra-Low Dispersion) lenses and an ED (Extra-Low Dispersion) lens, the lens system is comprised of 15 elements in 12 groups. The adoption of five special lenses makes it possible to meet the stringent LEICA standard for exceptional image quality with high resolution and minimum distortion. In general, flare is commonly seen around the periphery of a point source with many high-speed lenses when a large aperture is employed. However, the new LEICA DG SUMMILUX 12mm/F1.4 ASPH. achieves high resolution from the center of the image to the corners by suppressing this flare. Users can take advantage of this lens to shoot a brilliant night skies or night scenes containing illumination to capture true-to-life images with minimal blurring and distortion at the edges. The multi-coated lens elements also minimize ghosting and flaring.

Incorporating an inner focus drive system and a stepping motor, the new LEICA DG SUMMILUX 12mm/F1.4 ASPH. is capable of smooth, silent operation together with the camera’s high-speed, high-precision contrast AF system for both photo and video recording. It is also compatible with the sensor drive at a maximum of 240 fps to take full advantage of cameras with high-speed AF. This stunning AF performance is excellent for recording 4K videos, where precise focusing is essential.

The LEICA DG SUMMILUX 12mm/F1.4 ASPH. comes with an aperture ring for direct, intuitive aperture control. Nine blades give the aperture a rounded shape that produces an attractively smooth effect in out-of-focus areas when shooting at larger aperture settings. A highly reliable metal mount assures durability for repeated use. The lens mount, the barrel and the hood are all made of metal to provide a sleek, sophisticated design that matches the entire line-up of LUMIX G Digital Single Lens Mirrorless (DSLM) cameras.

Specs

  • 14 elements in 10 groups (including an ED glass element)

Nikon updates its portfolio of DX NIKKOR lenses with two lightweight super-telephoto zooms: the AF-P DX NIKKOR 70–300mm f/4.5–6.3G ED VR and the AF-P DX NIKKOR 70–300mm f/4.5–6.3G ED.

Fast, quiet, and precise, these lenses are a great way to explore the creative advantages of telephoto photography. Whether you’re shooting distant subjects, travel photos, or amateur wildlife images, the versatile 70-300mm focal range magnifies the action. An extra-low dispersion (ED) glass element in each lens delivers images with vivid colour, crisp detail, and perfectly rendered contrast. Both lenses feature Nikon’s new, superbly quiet AF-P Stepping Motor, which makes them ideal for shooting video as well as stills. The AF-P DX NIKKOR 70–300mm ED VR features Nikon’s Vibration Reduction technology for clear, blur-free images even when shooting at the far end of the telephoto range. And both lenses boast a serious size advantage: their compact build makes them comfortable to carry and ensures balanced handling when used together with Nikon’s smaller entry-level D-SLRs*.

Zara Livingston, Junior Product Manager for D-SLRs, Lenses and Accessories at Nikon UK, says: “The new 70-300mm AF-P NIKKOR lenses are great additions to the NIKKOR lens line-up and ideal for photographers looking to extend their reach. The streamlined design makes carrying them easy, and these are the first telephoto lenses to feature Nikon’s AF-P focus motor.”

Stepping Motor

Nikon’s Stepping Motor ensures smooth, fast autofocus. When zooming in to capture a photo, subjects come into focus quickly and easily. When shooting video footage, the motor allows you to smoothly shift focus from subject to subject with practically no drive noise, ensuring your movie isn’t ruined by the sound of the lens focusing.

Simplified control, lightweight build

Both of these super-telephoto lenses offer first-time users a more intuitive way to shoot. Users can switch between Auto Focus and Manual Focus using the camera menu. With no switches on the lens barrel itself, there’s no chance of accidentally changing settings when the time comes to take the shot. These lenses let you pack light, too. The AF-P DX NIKKOR 70–300mm f/4.5–6.3G ED weighs in at just 400 g, while the AF-P DX NIKKOR 70–300mm f/4.5–6.3G ED VR weighs 415 g.

150-600mm Tamron SP zoom lens http://www.personal-view.com/talks/discussion/8690/150-600mm-tamron-sp-zoom-lens Thu, 07 Nov 2013 00:20:53 -0700 Vitaliy_Kiselev 8690@/talks/discussions image

Note: Price and availability are unknown at the moment.

Lens Features:

  1. 4x ultra-telephoto zoom lens with a focal length range of 150mm to 600mm The focal length range of this lens was extended by 50mm on the wide-angle side and 100mm on the telephoto side compared to the existing model (Model A08), making it possible to take even more striking photographs of birds, wildlife, sports, and other distant subjects. Mounted on APS-C DSLR cameras, it has a stunning equivalent focal length range of 233mm to 930mm, almost to 1000mm.

  2. World class image quality
    Employing 20 elements in 13 groups and boasting an advanced optical design, it delivers a superior balance of resolution and contrast for sharp, clear images. The front group contains three LD (Low Dispersion) glass elements (two in the first group, one in the third) for enhanced optical correction effectiveness, enabling the lens to thoroughly compensate for on-axis aberrations at the telephoto end.
    The lens also adopts eBAND Coating, developed from state-of-the-art coating technologies, and conventional BBAR(Broad-Band Anti-Reflection) Coating to greatly suppress ghosting and flare even when shooting under adverse lighting conditions.

  3. Achieves a 600mm focal length in a compact easy-to-handle package
    Ingenious optical design features minimize the movement of lens groups within the lens when zooming. This reduces the amount of barrel extension needed to cover the complete focusing range, making the entire lens more compact.

  4. Beautiful background blur effects
    Adopting a 9 blade circular diaphragm enables users to create beautiful background blur effects (bokeh), which provide even greater potential for creative expression. This circular diaphragm retains a nearly circular shape even at two stops down from its maximum aperture.

  5. Vibration Compensation
    Tamron’s proprietary VC (Vibration Compensation) image stabilization system uses a three-coil system, delivering significantly sharper images and creating greater opportunities for handheld ultra-telephoto photography.

  6. Comfortable autofocus
    Tamron’s new SP 150-600mm F/5-6.3 Di VC USD features a USD (Ultrasonic Silent Drive) ultrasonic motor drive*³ for swift and accurate AF response, it delivers high torque, very fast response times, and very low noise. The full-time manual focus mechanism allows users to make fine manual focus adjustments at any time even when AF is engaged.

  7. New elegant, high-class external finish
    Tamron has upgraded the cosmetic design and finish of this lens to create a more sophisticated, high-end look in keeping with the demands of discerning full-frame DSLR users.
    Employing a sophisticated linear pattern rubber grip on the zoom and focus rings and an attractive and stylish tungsten silver name-brand ring, this newly designed model accentuates its visceral presence with understated elegance and class.

  8. Easy-to-use tripod mount
    The tripod mount has been completely redesigned to provide superior stability, durability, ease of use, and portability.

  9. Comes with "SILKYPIX Developer Studio for Tamron", RAW image development processing software for Tamron’s SP lenses

The global optics brand, Samyang Optics (http://www.samyanglensglobal.com) today announced the long-awaited launch of two autofocus lenses: 14mm F2.8 and 50mm F1.4 lenses for Sony E mount Mirrorless cameras with full frame sensor size. The new 14mm and 50mm are the widest and brightest lenses in their classand offer superb quality images to photographers. This launching expands the boundaries of Samyang Optics photo lens line-up from manual focus only, to now include autofocus lenses.

Optimised Optical Design as Full Frame Mirrorless Camera Lens

Both 14mm F2.8 ED AS IF UMC and 50mm F1.4 AS IF UMC are specifically designed to work in harmony with full frame mirrorless cameras in Sony E mount. The flow of light is devised based on the uniqueness of the distance from glass to sensor in mirrorless cameras to create optimal performance. Along with portability of mirrorless lenses, the 14mm F2.8 and 50mm F1.4 are compatible with full frame sensors to deliver the wideness and sharpnessof image to photographers.

The 67mm filter diameter brings the maximum amount of light into the lens to create the best work of light in photography. The 14mm F2.8 is the widest angle available in the market and the F1.4 of 50mm and F2.8 of 14mm apertures are by far the brightest of full frame mirrorless lenses, offeringa beautiful bokeh effect and the best quality images under various exposure conditions.

Based on Samyang Optics’ exceptional optical technology, aspherical lenses have been included in both lenses to minimise aberration and unnecessary light dispersion, delivering high resolution from the centre to the corners of the image.

AF Performance and Ergonomic Design Based on Class-Leading Technology

These new products will be the first autofocus lenses in over 40 years of Samyang’s class-leading core optics technologies. Samyang has captured the essence of world leading image technology with their manual focus lenses and reinterpreted it into autofocus lenses. Photographers now can enjoy the prime manual lens image quality and autofocus lens. These new 14mm F2.8 and 50mm F1.4 are compatible with both phase detect and contrast detect sensors to operate fast and accurate focus detection.

The 67mm filter diameter is also the result of years of R&D for best handling, by adding stability to the photo-taking experience. Also the minimal and sleek design and metal-housing solidify the build quality with the internal focus system.

These two new autofocus lenses from Samyang Optics will be exhibited at the Photo & Imaging 2016 Show in Seoul, South Korea. The lenses will be globally available from July 2016. Further details, pricing and availability will follow.

Samyang Optics introduced new manual focus lenses for full frame DSLR cameras: 20mm F1.8 photo lens and 20mm T1.9 cine lens. As known for the brand’s wide and bright lenses, Samyang 20mm series adopted bright F1.8 aperture to provide perfect wide angle for interior shots and landscapes.

The Samyang 20mm F1.8 ED AS UMC and 20mm T1.9 ED AS UMC are wide angle manual focus lenses for DSLR cameras with full frame sensor size. It has been a year that Samyang launched the full frame DSLR camera lens and latest lens was the 135mm series.

Samyang Lenses are known for its bright apertures and so does this Samyang 20mm series. These two lenses have a bright aperture of F1.8, equivalent of T1.9 for cine lenses, to offer a best quality images under various lighting conditions. Also, the lightweight Samyang 20mm series brings the portability to increase the convenience.

Based on Samyang Optics’ exceptional optical technology, 13 glasses in 12 groups are used to create the most optimal image quality.

FS: Vintage macro reproduction lens KORREKTAR 150mm f6.3 http://www.personal-view.com/talks/discussion/15456/-fs-vintage-macro-reproduction-lens-korrektar-150mm-f6.3- Tue, 02 Aug 2016 07:30:18 -0600 neirotransformer 15456@/talks/discussions Rare lens for sale. It was made for some kind of reproduction machines and covers huge 12x18 cm frame. Probably another copy of industrial Zeiss or Nikkor (as all things done in USSR). It covers 12x18 cm frame, so on small sensors in regular (not macro) mode its not so sharp as smaller microplanars. The good thing about this lens is that in macro mode you can be very very far from object. It has perfect round bokeh at any F-stop and very flat and even image area. Works well for macro and for landscape too. The image is very filmic. The iris is smooth, glass is very clear.

The lens comes with Rafcamera M45-M42 adapter and with PZF macro bellows (Its not the most precise bellows in the world, but its perfect for this lens because it extends 2x more than other usual more expensive bellows)

Located in Ukraine, Odessa city. Will ship worldwide. Can accept only Payoneer (Make A Payment service from Payoneer to Payoneer account 0% fee) or any Card to Payoneer (Request a Payment service) with 3% fee. Ask $200 ( or $180 without macro bellows) + shipping and payment fees.

Sell it because unfortunately it vignettes on BMMCC sensor and i can't accept this. This lens made for 16 mm cinema. It will fit well to Panasonic GH, Ursa 4.6k, RED, Nikon 1 in 1:1 crop mode or to any camera with small sensor, like Pentax Q or 2/3" CCTV camera. Its wide. its not perfect but has own character. Its slightly soft and dreamy wide open and rather sharp starting from T2.8 and T4. It is a low contrast lens, but you can boost contrast in post easily to match other lenses. It don't have a focus ring. It very sensitive to flange distance changes. I shimmed it to the lens mount adapter with 0.1mm tape so it focus perfect even wide open. The lens is in very nice external shape, glass is clear, maybe few cleaning micro marks in front and some dust specks inside if look too deep with flash-light. I also find that at T11 and 16 i start to see two small dark spots (see the images in dropbox folder). Seems it never was disassembled or serviced. The iris ring is clickless, working very smooth.

Discussion on lenses and perception across camera systems. http://www.personal-view.com/talks/discussion/6453/discussion-on-lenses-and-perception-across-camera-systems. Wed, 20 Mar 2013 18:05:22 -0600 RRRR 6453@/talks/discussions This is not a thread to debate or explain physics. This is a thread which hopefully can become a resource for lens selection for so called crop sensors.

The other day I was involved in a discussion about "85mm" lenses, and the differences between the characteristics of a certain FOV lens on "full frame", compared to how it looks on a crop sensor. A "native" lens can be designed to perform just like it´s other sized sibling, but when one is into vintage lenses / lenses that can be used on multiple systems it gets far more complicated! Lately I´ve been thinking a lot about lenses that work across different camera systems and the different qualities that are exhibited, depending on the size of the sensor. I´m not thinking so much about the obvious depth of field related changes as to how the overall feel of the image and subtle optical imperfections alter the image with the same lens used on different systems. I´d like to think of aps-c or s35 as base sensor / imager size over "full frame", at least for us who have video as the main area of camera usage, however, many lenses where designed for "full frame" and although the differences on s35 and aps-c can be rather small, I find the differences increase exponentially the smaller imager you put it on.

Hence I have come to search for vintage full frame lenses which will exhibit appealing qualities on a gh2 or a blackmagic design cinema camera. Now, what is appealing to me might not be appealing to you, but I will try to define my own criteria and I hope you can supply yours and add to this thread.

I have been building two main sets of vintage still lenses after ditching my canon fd´s (they were not getting the use to justify having them). For one, I have been buying c/y zeiss optics and I have been adding m42 mount lenses as I have come across them or found some interesting aspect which could fit in with the rest. The c/y´s will no doubt be a mainstay in my arsenale for years, however the ultimate reason why I pulled the trigger on the full set was the advent of the metabones speedbooster – I much prefer how they look on a slightly bigger sensor over a smaller one and I have high hopes for the speedbooster. The reasons for the preferred vicinity to "native sensor size" are:

  1. less pronounced CA. I have become a bit allergic to aberrations of late.
  2. nicer transition to OOF areas, wide open or stopped down.
  3. More obvious contrast/microcontrast "sweet spot". (I think this is down to a slightly larger FOV)
  4. Usability wide open, much in line with the criteria above. A lens which looks sharp in the center on full frame or aps-c might just look soft on a smaller sensor because there´s less contrast between edge and center.

With the m42´s it´s different. I like very much how they look on the gh2 AND f.i. the fs700 or BMD, so I find them extremely useful for video, across systems. So what is it I´ve been looking for?

  1. Low(ish) contrast
  2. Pleasing (sort of neutral) OOF and bokeh, also when stopped down.
  3. good price / performance ratio.
  4. great CA control
  5. reasonable color match
  6. good distortion control / flat focal field

I have mainly been searching through lens databases (on possible candidates), comparing sample images.

Now, this set consists today of the following lenses:

20mm flektogon f2.8 29mm meyer optik, pentacon f2.8 37mm Mir-1b f2.8 50mm Pancolar f1.8 58mm Helios f2 135mm meyer optik orestor f2.8 200mm meyer optik orestegor f4

I´m still looking to add a few but for the ones I have / I´ve had I can say the following:

20mm flektogon - I prefer the f4, as it´s tack sharp wide open. (f2.8 needs to be stopped down to 4-5.6) 29mm Meyer optik is sharper / has less blooming (coma) than the pentacon wide open.. maybe half a stop brighter as well - otherwise they are remarkably similar - both useful wide open. Bokeh can be both expressive and sort of neutral depending on where you place the focal field / subject and f-stop. 37mm Mir is a great "normal" lens on the gh2. Too slow? No. Just right. I want to add a macro ring to help out close focusing. Great value for money and beautiful OOF transitions thanks to the 10 blade aperture. 50mm pancolar - a bit too low in contrast to fit the others well. Not a fan of it´s bokeh. 58mm helios f2 - rock´n roll short tele on the gh2. Wonderful out of focus rendition and also nice transitions thanks to the round aperture. 135mm meyer optik - beautiful and tack sharp tele. Notoriously nice OOF / Bokeh rendition. Low in contrast and needs a push in post to match most of the other lenses. 200mm meyer ... - used it very sparingly so far. Not super sharp wide open. Not a preferred lens on gh2 sensor.

In general, I´ve had some issues with mechanics in cold conditions (needed to clean out and lubricate some helicoids) but they have been put to very good use already. I traded away a 35mm flektogon which I felt was a tad harsh in contrast in comparison to the others anyway (great lens tho). Another thing which is down to physics - the wider the lens, the more restless / harsher the bokeh is. The performance of a certain FOV does not quite match what you´d get on a larger sensor but this will only be a problem in case you are looking for really wide lenses in which case you are better off with native lenses anyway. The difference is mainly where you place the camera. (between different sensor sizes).

Note: I believe it´s difficult to switch lenses with acute focal fields between different sized imagers and not get very differing results.. For my m42 set I´d normally not use all for one production but choose a few depending on priority, like f.i. one or two wides, one or two tele´s to contain the slight differences in coatings, color e.t.c. However, they match remarkably well despite transgressing manufacturers and brands. I´d guess it´s because they are in the vicinity of one lineage of optics manufacturing.

Samples to follow.

Is there a zoom lens for full frame with mechanical focus? http://www.personal-view.com/talks/discussion/15371/is-there-a-zoom-lens-for-full-frame-with-mechanical-focus Sat, 16 Jul 2016 09:24:07 -0600 JackBayer 15371@/talks/discussions Hello!

I am looking for a decent zoom lens (Standard range, 24-70 for example) that covers a full frame sensor and has non electrical manual focus for use with a follow focus. I don't need auto focus but it wouldn't hurt either.

Is there such a thing?

Thanks!
