Testing out the Voigtlander Nokton 25mm f/0.95 Lens and my new GH2 (No HACK) http://www.personal-view.com/talks/discussion/5546/testing-out-the-voigtlander-nokton-25mm-f0.95-lens-and-my-new-gh2-no-hack Fri, 21 Dec 2012 12:37:44 -0700 disease8 5546@/talks/discussions I had a play around with the GH2 in a Graveyard in South London. It was a very cold day and so quite hard to keep everything smooth. I was using a super cheap £30 tripod a Velbon C-400 which comes with a PH-24B fluid head. I also experimented with a technique where you slowly tip the tripod towards an object/subject whilst tipping the tripod head up to keep it level. It gives the impression that you are using a slider track.

Although I have worked with still photography and video operating I haven't had much experience with this more artistic film work so I would love some feedback. Most of the shots I was on a very wide aperture, around 0.95-1.4 and kept my ISO very low. I haven't really done any colour correction and I am not entirely happy with the edit. I did it more as a test and rushed the edit a little whilst at a friends house (so I couldn't concentrate 100%). One thing I have noticed is that there is a "judder" effect going on constantly throughout, like it is missing some frames. Not sure if this is because I am using a cracked version of premiere or its the way I exported it.

Anyway here it is (its kind of depressing).

12-50mm f/3.5-6.3 Olympus official topic http://www.personal-view.com/talks/discussion/1722/12-50mm-f3.5-6.3-olympus-official-topic Tue, 13 Dec 2011 06:38:24 -0700 Vitaliy_Kiselev 1722@/talks/discussions

* Super fast AF
* Powerzoom
* Lack of stabilization
* Focal length: 12-50mm
* Aperture: f/3.5-6.3
* Close focusing: 0.35 meter (0.98 ft)
* Macro: 0.2 to 0.5 meter (0.66-1.6 ft)
* Filter size: 52
* Focus and Aperture rings
* Powerzoom button on the left side of the lens
* $499 estimated price
* Available Mid-January 2012

Olympus adds to its powerfully simple and growing PEN family with the first fully-compatible interchangeable Micro Four Thirds lens to incorporate an electronic motorized zoom. The M.ZUIKO DIGITAL ED 12-50mm F3.5-6.3 EZ (35mm equivalent 24–100mm) delivers smooth, quiet zooming that gives you versatility, portability and maximizes the performance of the Olympus PEN® compact system cameras.
The sophisticated new lens has a zoom ratio of approximately 4.2x, allowing photographers to capture anything from detailed, wide-angle group shots to medium telephoto-range images so you can get up close and personal for intimate portraits of children and pets – even indoors. The photographer can control the zooming speed by turning the barrel – slowly for drama, quickly for performance, or at an intermediate rate. Manual zooming is also available for those looking to take full control.
In macro mode, which can be set by pushing the zoom ring forward while depressing the macro button on the side of the lens, focusing is possible between 8 and 20 inches for close-up shooting with a maximum image magnification of 0.72X (35mm camera equivalent). The L-Fn (Lens Function) button suspends the autofocusing operation temporarily to avoid unintended focusing on obstacles that appear suddenly between the camera and the subject.
Perfect for brilliant still images and high-definition (HD) video capture, the Movie & Still Compatible (MSC) M.ZUIKO DIGITAL ED 12-50mm F3.5-6.3 EZ has also been enhanced with a linear motor that drives smooth and quiet autofocusing for stress-free shooting.
New lens elements and glass materials ensure the clearest possible imaging performance, and the proven dust and splashproof mechanism originally featured in the Four Thirds SHG (Super High Grade) series lenses is now incorporated for the first time in a Micro Four Thirds System lens. Multiple sealing rings, fitted throughout the lens body, prevent water splashes and dust from penetrating, making the M.ZUIKO DIGITAL ED 12-50mm f3.5-6.3 EZ a versatile zoom lens for the toughest conditions.

I'm selling a few things, all in very good condition. I have a Rode NTG-2 microphone that I'm selling for $150. That includes free shipping and comes with the foam wind screen and the Rode soft carry case. I also have 2 Pentax Lenses that I would say are perfect, but because I'm not a lens expert I'll just call them "very good". I used them briefly but decided to stick with my 28mm & 50mm Lomo lenses for the particular look I'm going for on my next project. I don't see any problems at all with the glass, and the images looked perfectly clean when I used them on my GH2. I'm selling them each for $100. That includes free shipping, as well as a free Pentax to m43 adapter, so these are ready to use once you receive them. They both have front and rear caps, as well as a clear screw on filter for protection. If you want to buy the 2 lenses I can offer them both for $180.

I keep all my gear properly stored in Pelican cases, and will also be very carefully wrapping and packing these before I ship them to you.

Thanks, Matt

What are the benefits of a constant aperture lens? http://www.personal-view.com/talks/discussion/11367/what-are-the-benefits-of-a-constant-aperture-lens Tue, 23 Sep 2014 08:01:39 -0600 mpgxsvcd 11367@/talks/discussions It seems like all of the high end lenses are constant aperture. What are the benefits and drawbacks of a constant aperture lens?

The biggest benefit I can think of is that the exposure will stay constant as you zoom. You can fix the shutter speed, focal ratio, and ISO values and then zoom without needing to change them. That sounds great but do we really need that?

With cameras that have Auto ISO available in manual mode can’t you just let the auto ISO control the exposure while you zoom?

Also aren’t all lenses constant aperture, just not always at their wide open apertures? If you stop down to the minimum aperture of the lens then the aperture will remain fixed in aperture priority or manual mode while you zoom even if the lens isn’t a true “Constant Aperture” lens.

What happens as you zoom? Aren’t these lenses still changing the aperture in order to keep it constant? Doesn’t that mean that your depth of field will change as you zoom? If the focal ratio of a not constant aperture zoom lens increases as you zoom in could it then keep depth of field constant as you zoom if so desired? Would that ever be desirable?

Couldn’t a constant aperture zoom lens have a slightly wider aperture or slightly longer focal length if it wasn’t a constant aperture lens wide open? Aren’t they crippling the lens slightly in order to make it constant aperture wide open?

Also what about being parfocal. Isn’t maintaining focus as you zoom more important than maintaining focal ratio especially in cases where you can let Auto ISO solve the changing exposure issue?

I am just curious as to why we insist on having constant aperture lenses. To me the benefits of a constant aperture lens do not outweigh the benefits of a non-constant aperture lens as long as your camera allows auto ISO in the modes you are shooting with.

With that being said the 35-100mm F2.8 is pretty much the only lens I use on my GH4 now. However, I really don’t zoom that often while filming so I am not sure I use it to its full abilities.

Small and lightweight zoom for S35 with good focal range? http://www.personal-view.com/talks/discussion/11319/small-and-lightweight-zoom-for-s35-with-good-focal-range Wed, 17 Sep 2014 20:34:05 -0600 Brody 11319@/talks/discussions Hi guys, I'm looking to buy a zoom that covers S35 with an f/stop of about 2.8 (ideally fixed) that would be small and lightweight more or less in the range of something like 20-85mm and/or 35-120mm.

I hope to avoid still lenses for mechanical reasons and also to get that "warmth" and organic nature one might get from older cine lenses. I might consider older still lenses that are all manual and have good mechanics.

Versatility, size and weight are my major concerns. I'm not trying to find optical perfection here. In fact imperfections (low corner sharpness, flaring, etc.) are welcomed as I prefer older glass with digital capture anyways if it gives me good center sharpness.

Modern cine zooms are huge and bulky and expensive and I'm not looking to rent. That's why I've been thinking about older lenses mostly. Ideally something that could be converted to EF mount. Flexible budget depending on the lens.

I've been digging the net for some days now and I've come mostly empty handed. Only option I found was this small 1kg Optar 25-80 T3.4 but I was hoping to widen my options. (http://www.reduser.net/forum/showthread.php?31664-Optar-25-80mm-PL-mt-Lens-for-sale)
