14mm F/2.8 version: Question: Any users notice any vignetting problems?
446654
I did not notice any vignetting, but I was using the 14mm f/2.8L II version, which supposedly eliminates that, espically when stopped down to 5.6 - 8.0 range. What I DID find was an absolute unacceptable sharpness falloff about 1/4 from the edge. I thought for a while that I was shipped the original 14mm, because it was notorious for that. Alas, it was the II version and Amazon accepted it back, no questions asked. I am considering ordering another, because there *is* the occasional lemon. I may have just gotten one. A good site for comparisons: &lt;http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=454&Camera=453&Sample=0&FLI=0&API=4&LensComp=280&CameraComp=9&SampleComp=0&FLIComp=0&APIComp=4&gt; or http://tinyurl.com/ygt355j Good luck!

Depending upon your telescope optics I see no reason why using the diagonal should be a problem. Some telescopes have light baffles that may cause vignetting depending on focal length.

I don't believe you do - I get no vignetting on my Tokina 12-28 at 12mm on my DX3200 at all, not even a trace. Just make sure it's the only filter on the lens when in use, and you should be fine. :) To be perfectly frank, I'm not sure how I'd manage a thin version - the turn ring on this one is about as fine and thin as I can easily manage. Anything thinner and I suspect I'd be fumbling at times.

My polarizer is made by Hoya, a Japanese company. Vignetting is a common problem at wide angles, e.g. 18 mm. If you're using another filter to protect the lens (UV or skylight) try taking it off & just using the polarizing filter. Getting the filter as close to the lens as possible is the goal. Can also get a step up ring and a larger polarizer, e.g. 77 mm.

same answer as patrick A. it works. any c mount wider than 25mm will cause vignetting.

For the 24-105, you shouldn't have problems with vignetting if you've got a single filter (no stacking thereof) and are shooting with with your aperture closed down a bit. Good Luck!

I have not had exposure issues but I have had focus issues. Not really issues, as much as just not being happy with the focal range at all, or the autofocus system. If you are shooting auto I can see you having problems as the auto systems just do not seem to be up to par compared to other platforms

It's full frame. That's all I can tell you......There is also a Novoflex version NEX/NIKYou didn't mention what lenses you have? It's the lenses that determine the vignetting.

No. You need a 50mm polarizer. You could get an adapter ring but that can start to cause vignetting at the corners. Get a 50mm polarizer.

F-stop/aperture does not represent clarity, but no, it does not lose a stop. I haven't had any cropped images, nor have I even noticed any vignetting as a result of using this. The widest lens I've used with this is a 28mm

Gosh, I really wouldn't know how to answer that. I have the original (ole') GF1, the GF5, the GX1, and the G5 - none of which have the issues that you mentioned. Additionally, I had not previously heard about that LCD issue and I tend to post and read on quite a few photography forums. All I can say is that I've not experienced this at all - and I have two GX-1's (one with the 14-45 OIS on it, and the other with the 45-200 OIS). Ben

Yes, I have not had any issues with this lens, in fact, I love it. I use the auto setting on the camera and all pics have been great!

I have a canon 24-70mm f2.8 (very comparable with your Tamron) and as with all variable ND filters there is a degree of vignetting at the higher points, especially if you tend towards more full daylight shooting. the Tiffen is manageable however and still offers up great image quality.

Just beware of putting subjects on the edge of the frame when @ 17mm - 25mm. You are going to get horizontal distortion, not a ton but its not flattering to those on the side. No one would ever notice this on a landscape photo but when its a person... Pretty easy to fix in post if you have a decent software. Its a great lens though!

It will attach with a filter on, as it doesn't screw into threads in lense.I haven't had the vignetting problem with it.

The adapter and UV filter will probably cause vignetting at the wide angle setting of G10. Not fatal but to be considered.

I've used it on mine and it works, but it was optimized for APS-C sensors, so the corners might get wonky. "The phoblographer" website also verifies this in their testing of the lens. I've noticed little to no vignetting on my photos though.
