Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world's most impressive lines of lenses, cameras and flashes, today announced its newest addition to the Sigma Art line of lenses for full-frame cameras, the 24-105mm F4 DG OS HSM.

True to its categorization as a Sigma Art lens, the new 24-105mm F4 DG OS HSM is designed for artistic expression and top-notch image quality. This versatile lens covers the basic shooting range from wide to medium tele with an inner focusing system that eliminates front lens rotation, enhancing the lens stability and allowing the use of circular polarizing filters. It also boasts a constant aperture of F4, and contains Sigma’s proprietary Optical Stabilizer (OS) technology to compensate for camera shake. Moreover, it was designed to surpass the required quality inspection of every Global Vision lens with Sigma’s own modulation transfer function (MTF) “A1” measuring system to create new optical standard to align with the high-spec cameras on today’s market.

“For many years, Sigma users have been seeking a standard zoom lens in this range,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “The 24-105mm F4 DG OS HSM is yet another example of Sigma listening to its users and delivering new and innovative products with the highest image quality.”

Amir-Hamzeh added that this new lens combines the largest possible fixed aperture to zoom ratio that will maintain optimal integrity for many kinds of photography, including landscapes, architecture, portraiture and still-life. With a minimum focusing distance of 45cm and a maximum magnification ratio of 1:4.6, this lens is also excellent for close-up photography. High-performance glass elements, including SLD, FLD, which is equal to fluorite, and glass- molded single- and double-sided aspheric lenses have been included into the optical system to prevent aberration, field curvature, distortions and color aberration. The 24-105mm F4 DG OS HSM lens is also able to suppress chromatic aberration very effectively at the telephoto-end, and can achieve superior image quality throughout the zoom range. Unlike lenses with similar specifications, this lens overcomes low peripheral brightness. Although it is designed for full frame cameras, it also works with APS-C sensors, giving an increase to focal length.

The lens’ Hyper Sonic Motor (HSM) ensures a silent, high-speed auto focus function and enables full-time manual focusing capability. The 24-105mm is also compatible with Sigma’s USB dock allowing photographers to update its firmware and change focus parameters using Sigma's Optimization Pro software. It is also compatible with Sigma’s recently announced Mount Conversion Service.

Most wanted ANAMORPHIC lens http://www.personal-view.com/talks/discussion/4466/most-wanted-anamorphic-lens Tue, 04 Sep 2012 15:35:25 -0600 slrmagic 4466@/talks/discussions Dear All,

We have received 4 email requests from members of this forum on the possibility of designing an Anamorphic lens. We had this thought for the past year and did a lot of research. There is one common request which is to have horizontal flares. The others requests did not have any common grounds. We came up with an idea for a 25mm f/3.2 1.35x or 35mm f/3.2 1.35x Anamorphic lens for micro four thirds. Shooting at 16:9 would give a 2.40:1 anamorphic output. Just before we decided to go ahead with the project we had a second thought. 2 Years ago we asked openly on dpreview.com forum for what photographers wanted and the general consensus was our SLR Magic HyperPrime 12mm T1.6 lens.


It did not fulfill the needs and wants of everyone but we made what most people agreed on by means of a discussion. It ended up being a popular lens that we still are having problems meeting demand and we think it had a big part to do with asking photographers. If we did not ask around we probably made a 12mm f/2.8 lens. As it turned out quite well last time we want to make our next lens an open discussion again.

Here are some of the possible options we received and please feel free to throw in extra ideas. I hope people experienced with shooting in Anamorphic can also throw in ideas.

Anamorphic Adapter (1.33x, 1.5x, 1.75x, 2x) Dedicated mFT Anamorphic adapter for reasonable size Anamorphic adapter compatible with FF lenses 50mm f/2.8 Anamorphic lens (FF, APS-C, or mFT) Expected MSRP (Sad fact but it as direct correlation to IQ)

Kind rgds., SLR Magic Team

P.S. We will be at Photokina 2012 and would like to welcome any cinematographers with Anamorphic lens ideas to drop by our booth for idea exchange! We will be in Hall 3.1 B059

Great lens, little distortion, sharp with good contrast. This lens comes to life as most do around F4-8, but can be pushed either way and still produce a nice image. If your a m4/3rds shooter, I would go for it in that mount to do away with an adapter due to the size. This lens is smooth with a follow focus, although for this vid, I shot it stock, focus was all done in hand.

Finally comes the first alternative to voigtlander 17.5mm! And to think that the 17mm could also be better in terms of focal length: in fact the crop in 16:9 mode should be a bit more of 2x, is not it? So to get even closer to the equivalent 35mm, it's better than 17.5 (just to make a speech of fanaticism, but there is!) So: what expectations we can feed? The build quality does not come close to voigtlander perhaps, but in terms of image quality, now we should be very close, is not it? Also the price will certainly be lower, you know if you can buy from a third party and take advantage of a street price lower? Let's keep up to date

Hidden gems among lenses http://www.personal-view.com/talks/discussion/80/hidden-gems-among-lenses Thu, 12 May 2011 00:39:39 -0600 Vitaliy_Kiselev 80@/talks/discussions
First one - Vivitar 28-200mm F3.5-5.3

1) Buy only original 28-200mm as in picture below. Tokina is absolutely different lens with different optical formula (look at crop from Vivitar box, Tokina have fewer elements).
2) For Pentax, lens could come either in PK/A or PK A/R mounts. In former you must remoive Ricoh pin. On both you must use file to remove excessive lever protection.
3) Closed down, lens is PP friend. Good wide open, but as on many old lenses have some abberations. Contrast is lower due to many glass surfaces and not top-notch coatings. Abberations are almost absent if close down (see below).
4) Corners are controlled quite well.

9mm F8 body cap Olympus. Maybe cheapest m43 fisheye. http://www.personal-view.com/talks/discussion/9950/9mm-f8-body-cap-olympus.-maybe-cheapest-m43-fisheye. Sun, 23 Mar 2014 11:11:40 -0600 ahbleza 9950@/talks/discussions image

Olympus' tactic of playing down the optical performance of this lens need not be necessary. Even though this lens only costs £90 and is little more than a body cap with some glass in it, it is still capable of delivering decent quality images. Those who fancy experimenting with the fisheye look but don't relish the thought of forking out proper fisheye money, this lens is ideal.


Overall, this lens is fun to use, thanks to its compact size and fuss-free operation.

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

24mm F1.4 Samyang official topic http://www.personal-view.com/talks/discussion/658/24mm-f1.4-samyang-official-topic Fri, 12 Aug 2011 18:08:48 -0600 Vitaliy_Kiselev 658@/talks/discussions
Optics of the lens has been constructed based on the system of 13 lenses arranged in 12 groups. It should be noted that 4 lenses has been made of the low-dispersion glass (ED), while two another are aspheric lenses. We have also employed multi-layered and anti-reflexive coatings of UMC type adding to the perfect light transmission. Samyang 24 mm F1.4 ED AS UMC has been designed to work with most popular reflex cameras produced by renown manufacturers and equipped with small-image sensors or smaller. The lens will be available with a mount for the following systems: Canon, Four Thirds, Nikon AE, Pentax, Samsung NX and Sony Alpha.


24mm focus is tailor-made for most of the sensors available on the market today. In the case of full-frame cameras, it constitutes a high-quality wide-angle lens perfect for street, landscape and architecture shooting. Whereas photographers using DX sensors will get just perfect lens for the purposes of calmer journalist and landscape photography. The lens attached to Four Thirds cameras will create a universal and bright construction corresponding to the 50mm focus.


The lens should be available for sale by the end of the year or at the beginning of 2012. The exact price will be announced at a later date. Soon, we will be able to present sample photos taken with this sophisticated device.

Lens the size of a galaxy http://www.personal-view.com/talks/discussion/9821/lens-the-size-of-a-galaxy Sun, 09 Mar 2014 10:12:38 -0600 maxr 9821@/talks/discussions The video is a bit... well "Galileo in your face!" like, not so much actual dissection of methods used.

Source: NASA

Would you believe, bigger than an entire galaxy? At the January 2014 meeting of the American Astronomical Society, researchers revealed a patch of sky seen through a lens more than 500,000 light years wide.

The “lens” is actually a massive cluster of galaxies known as Abell 2744. As predicted by Einstein’s Theory of General Relativity, the mass of the cluster warps the fabric of space around it. Starlight passing by is bent and magnified, much like an ordinary lens except on a vastly larger scale.

Lately, the Hubble Space Telescope, along with the Spitzer Space Telescope and the Chandra X-ray Observatory, has been looking through this gravitational lens as part of a program called “Frontier Fields.” Auroras Underfoot (signup)

“Frontier Fields is an experiment to explore the first billion years of the Universe’s history,” says Matt Mountain from the Space Telescope Science Institute in Baltimore, Maryland. The question is, “Can we use Hubble’s exquisite image quality and Einstein’s theory of general relativity to search for the first galaxies?”

The answer seems to be “yes.” At the AAS meeting, an international team led by astronomers from the Instituto de Astrofísica de Canarias and La Laguna University discussed Hubble and Spitzer observations of the Abell 2744 cluster. Among the results was the discovery of one of the most distant galaxies ever seen—a star system 30 times smaller yet 10 times more active than our own Milky Way. Bursting with newborn stars, the firebrand is giving astronomers a rare glimpse of a galaxy born not long after the Big Bang itself.

Overall, the Hubble exposure of Abell2744 revealed almost 3,000 distant galaxies magnified as much as 10 to 20 times larger than they would normally appear. Without the boost of gravitational lensing, almost all of those background galaxies would be invisible.

Abell 2744 is just the beginning. Frontier Fields is targeting six galaxy clusters as gravitational lenses. Together, they form an array of mighty telescopes capable of probing the heavens as never before.

@Vitaliy any chance of having one of this in deals section? :P

I am sure that there is a topic here about this- however I can't find it after searching half the day.

I am wanting to know if the 14-140mm standard zoom lens is good for matte box usage etc... if not is there another lens? I mainly (only) use primes, so zoom would be just for documentary work. (so auto focus needed for run and gun)

Please let me know your thoughts, lots of guys on PV don't really have much nice to say regarding the 14-140, I have also used it and it is quite slow... :(

Thanks in advance...

Vizelex Light Cannon, Lens Turbo analog for m43 and NEX http://www.personal-view.com/talks/discussion/7356/vizelex-light-cannon-lens-turbo-analog-for-m43-and-nex Wed, 26 Jun 2013 01:57:22 -0600 Vitaliy_Kiselev 7356@/talks/discussions image


The Vizelex Light Cannon from Fotodiox Pro is an advanced lens mount adapter that not only attaches a Nikon Lens (including G & D type) to a Micro 4/3 (MFT) camera body, but has added light focusing optics which makes the lens wider by a 0.72x factor and increases the maximum aperture of the lens by 1 stop. This effectively allows use of your 35mm lenses on a crop sensor camera and not lose the angle of view normally associated with lens mount adapters (ie, 50mm lens stays roughly a 50mm lens equivalent).

Additionally, this light focusing optic gives a faster than normal aperture, turning a f/2.8 into the equivalent of a f/2.0; perfect for shooting in low light situations, when you need a faster shutter speed, or want a lower ISO sensitivity! The blue dial on the adapter is an aperture adjustment dial which allows the iris to be adjusted on even the Nikon G & D lenses; on older Nikon lenses with a aperture dial on the lens, the blue dial on the adapter can act as a depth of field preview lever allowing you to switch back and forth between wide open and stopped down to a certain f-stop.

As with all Fotodiox Pro series adapters, these adapters have been specially crafted to endure professional use. The leaf spring design in the adapter holds the lens tight to the camera body ensuring there is no play between the camera and the lens. The all metal design and polished surface is designed to guarantee a smooth mounting and long lasting experience. With unique styling, the lens mount adapter maintains a professional appearance. Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. Because of this “stop-down mode” will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. You can shoot with manual mode or aperture priority mode. Infinity focusing is guaranteed

Works very well on the Blackmagic Pocket. With 800g, it's lightweight enough to be used on the camera without additional lens support. Optically, it's better than for example Canon's V6/V7 zooms.

Since the Pocket has been available, this lens is very sought-after, and there are even Ebay offers for $1000. So it wasn't easy for me to figure out its fair and realistic market value.

I'm sure there is some psychological reasoning to wanting to have immaculate glass all the time, and having such scratches and even chips would rub most of us the wrong way, hence wanting to sell and replace the lens altogether.

I just bought a really nice lens for a very good price due to the fact it has a few chips and scratches on the front glass.
However, the seller states it has no effect on the image quality.
So I received the lens (a Canon FD 85mm F1.2 L), and initial tests do not show any signs of the chips or scratches, which is a win for me.

Does focal range matter concerning if the chip or scratch will show up in the image? I'm sure for macro lenses it would affect, but telephoto lenses might be more forgiving.

Anyone's thoughts and experiences in using chipped or scratched lenses, please provide!

One Perfect Lens? http://www.personal-view.com/talks/discussion/4880/one-perfect-lens Sat, 13 Oct 2012 00:21:55 -0600 matt_gh2 4880@/talks/discussions I was hoping to get some feedback from anyone who's used the Nikon 17-55 lens (with the f 2.8 available all the way through the zoom) or is familiar with it or other zoom lenses. What do you guys think about this lens as a single lens to shoot a narrative feature film. Our cinematographer wants to use one lens with a zoom as we are occasionally in cramped/tight locations, and the perfect shot is often between the fixed focal length lenses we have (18mm, 28, 50). I'm curious to see if anyone has any experience/knowledge of this lens' image quality, particularly when on a GH2 (will be using one of the Apocalypse Now settings. probably Boom - (thank you Driftwood))

The f 2.8 is pretty good for low light, but for very very low light we'll have ample lights at all time.

So what do you guys think...could this be one perfect lens?

Choosing gears for follow focus http://www.personal-view.com/talks/discussion/1568/choosing-gears-for-follow-focus Sun, 27 Nov 2011 20:30:20 -0700 johnnyblank 1568@/talks/discussions
http://www.ebay.com/itm/170648910462?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649 - they look like a good price.

Also I'd be interested in 360 gears, but haven't seen many on the market.]]>
What GH2 lens setup should I go with? http://www.personal-view.com/talks/discussion/9687/what-gh2-lens-setup-should-i-go-with Fri, 21 Feb 2014 22:16:51 -0700 regaliafilms 9687@/talks/discussions Hey, so I've had a GH2 for a bit now, and I'm in need of some nice lenses, I did some research and I came up with two different lens setups. Can't decide which one I should pick so if the community here could help me it would be very wonderful.

SETUP 1: Panasonic LUMIX G 20mm f/1.7, Sigma 30mm f/1.4, Canon EF 50mm f/1.8 II

SETUP 2: Tokina 11-16mm f/2.8, Nikon 28mm f/2.8D AF Nikkor , Nikon 50mm f/1.4D AF Nikkor Lens

I'm going to be filming for the most part, short films, and I want lenses that will give me a nice cinematic feel? (can't find the right word to use here) But, just want to get your guys' opinions on these setups and what you guys think I should do. I am on a budget here so if you are going to make other suggestions for setups please try to keep it below $850. Thanks!
