Has the AF problem been fixed on all the new 50/135 f/2.8 series?

I've had mine for approximately three years without any problems. It's a fantastic lens!

It depends. I'd check SN#. I still think Richoh has left the Pentax site as it was. It shouldn't be too hard to discover the cut off date for the motor issues that effected the early units. Mine is fine, but surprisingly my 60-250 2.8 has developed the AF lag. Go figure

I've had mine for a few years and haven't really had issues with it. I personally think it is a gorgeous lens.

None that I have noticed. The 18-200 lens for DX cameras had the problem on earlier version.

I had heard about the focus problems but we have had no problems with it what so ever. At wide open apertures, the depth of field is extremely tight, so I am guessing that some people who have less photographic experience were the ones complaining, because even at those apertures we are producing tack sharp images, on auto-focus or in manual on our Canon cameras, a T5i and a 60D. Sigma has released an updated version of the 50mm in their new "Art" lineup, so if you still have concerns, save up for that one. I've played with it at our local camera store and it is beautiful!

It's definitely no worse than the older version. But still sucks at AF speed. and has banding issues on some of the olympus bodies.

I've had mine for two years and it hasn't failed. Never heard anyone mention the AF failing. AF back focusing, or front focus, yes. But depending on what Canon body you're using most the time Micoadjustment enables you to tweak the lens to focus properly.

I too came from the MK II and can say, as others have pointed out, that the AF has been greatly improved in the MK III and there is a noticeable difference from MK II to MK III. The AF is responsive, snappy, and consistent. MK III's AF performs very well in low light, which is one area I found the MK II had trouble at times.

A review on the FZ7 indicated that AF (autofocus) needed to be on and just to press the button 1/2 way - wait for AF to work (a fewseconds) - then press full. Solved his problems. 2 or 3 reviewers stated same. Low ISOwas a "gimmee" w/o flash. Try autofocus (you are not using zoom and have light.

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.

Nikon has fixed the issues, but Nikon has not ever mentioned any problems either so just double check if you order one. I brought one less then a month ago without any issue tested and passed. It was found that one of the alignment stations was not calibrating correctly and about 20% of the models were effected according to Thom Hogan.

Had the same issue with a Nikon d5100, but after a few tries it was resolved. Check the following:1- for some reason, the lens didn't fit in with the camera, but after trying a couple of times it finally clicked into position2- there is a ring near the lens (the left part of the product picture) that must be slide out for the lens to autofocus. After you slide it you'll see the AF appear from under the ring, beore that there is only MF ( manual focus) visibleAfter these two the lens worked perfectlyHope it helps

I used 28-135 for more than 8 years and was happy with it. Recently, I purchased 24-105 and I was very surprised. AF is fast, image is clear, IS is working very good. 24-105 is excellent lens and much better than 28-135.

I don't know who said the EF 15/2.8 fisheye doesn't AF, but it does (unless a used/defective lens is being sold).

This is my second DMC FZ and no I haven't. If cleaning the lens well and not shooting towards the sun didn't fix the problem it had a unique flaw.

I scored the deal yesterday and have it in hand today. Serial Number 33.......... This tells me that it was produced in 2013, 3rd quarter so it definitely is the new sensor. It doesn't exibit lens droop or unwind. There is a little play in the lens when extended, but not like I saw on Utube videos of the problem. Battery is charging and I'm fired up!

I felt the same way when I got mine. It definitely has more resistance than the 18-55, but I think it's by design. With a more shallow depth of field at f1.2 you want a tighter focus ring for better control. Whether yours is abnormally resistant I don't know.

I have not had the camera for that long, only about 4 months, but have not had the problem occur. Before buying this model, I did a lot of research about the problem and was confident enough that it had been fixed, to shell out almost two grand for the camera. The Ken Rockwell website is a good source of information on Nikon and Canon cameras. I relied heavily on Ken Rockwell's opinion. On another note, I absolutely love everything about this camera.

Well the one i bought in 10-2013 does have a AF motor fairly quick, not to noisy unless theres a dead silence,but fir the most part its great at finding the focus point and snap,your done.
