Got mine today - doesn't work in continuous auto-focus mode and has quite a bit of vignetting. Is this just the way it is?

No, I love this lens. I havent noticed excessive vignetting, and it works fine in continuous auto-focus. I am shooting with a Nikon D300S and have been using the lens for a couple of months.

Mine works in continuos auto focus on both my D800E and D4. Yes it has a bit of vignetting wide open. A couple stops down not so much.

Hello! I have this same issue but with my Canon EF 85mm f/1.8 USM, so i guess uit was because the engine inside has a little problem and can only be useful in amanual mode. By any chance did you try to rotate the lens while you were on Automatic mode? Because that causes a rupture in the mechanism inside, if the problem is from the beggining then ask the dealer if it can fix it, otherwise use it in manual, it actually improves the quality pf the photos!

I've had mine for almost a year now. Unlike the previous posters, I haven't had any issues with focus. However, I have recently discovered 3 dead pixels in the CCD each separated pretty far from each other. I shrink most of my pictures for web use so it's not really an issue with me but it's not good when there's more than a couple of dead pixels in your CCD. Otherwise it's been pretty good; I do like it a lot.

I have the same equipment. The situation you describe is not normal in any lens mounted in any camera. But this combination lens/camera use to do it. Put the lens and the camera on manual focus, because the autofocus in this lens on this camera is a nightmare. But in manual mode, this lens is pristine, wonderful.

I have it for my dx frame and don't see any vignetting. I would imagine it would do that in you fx frame. But honesty its a fun lens.

I haven't written a review, and haven't even read the other reviews (yet), but I am *definitely* having the soft focus and out of focus problems you are referring to. I can take 10 consecutive pictures - same lighting/angle, etc. and maybe one will be a good picture, 4 not so good, and 5 completely unusable. I wonder if certain models cause this, or if some of these were just defective. I bought because of all the positive reviews, but wish I would've spoke up when I first received my camera.

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!

Nathan, I think it could be a firmware fix as well. I tried the continuous AF mode as well and it didn't help.

Yes. Sounds like a faulty lens. It works at all f stops. Check if there's a ton of dust in the back of the lens, but that's about all you can do. Also make sure that the camera works with other lenses at other f stops, so you're sure it's not the camera.

I think there can be many reasons for this - could be sharp in the small viewer but not so sharp when expanded -- could be due to camera shake, too slow shutter speed, or possibly the camera didn't grab the object you wanted to be the main focus. I will place the subject in the middle of the screen and half depress the button -- then move the camera to the composition I want, which holds the focus where I intended. It may not be the best autofocus on the market. But on the whole it's a one of a kind camera, a keeper for sure.

What do you mean by it doesn't recognize? If you're talking about the aperture control auto focus etc its normal because its a manual lens everything is controled on the lens. dont forget you have to enable the feature "release without Lens" otherwise you can take pictures :)Hope it helps

Bad one. Should just work smoothly. You should not notice it - except having to focus manually. ;)

I have the same camera. It's perfectly normal. It's just the camera focusing.

Good question! Go into the settings and adjust the flash to Auto, check other settings and adjust accordingly this may be a try and adjust type mine came out of the box shooting good pictures of good quality

Perfectly? 1. Have you been able to use the LCD display to set a timed interval exposure? 2. did you try to use the grip's arrow buttons to move the focus point while in live mode?

I noticed that you have to have proper lighting for the camera to focus. If not you never get the green light to take the picture. Outside of that may just be a dirty lense.

Mine has done this on occasion. It will focus out and then back in but usually in portrait mode. It seems for other settings it will not do that.
