Hmm, I think this is interesting... Photozone testing the Tamron 70-200/2.8 on a Canon EOS 50D

Used in conventional (phase-detection) AF mode it is reasonably fast and also accurate but we wouldn't really classify as suitable for action photography. Live-View (contrast-) AF is quite dismal and our test cameras were consistently unable to lock on even on our high contrast test targets - probably a first here in the lab but nothing to be proud of.

How is it with SDM or HSM lenses?
Slower. It deliberately doesn't operate them at full power. There will be a video showing this in our in-depth review.

Yup, it's the 1.0 firmware. I also tested the camera with the dfa 100 macro, fa200 2.8, fa 80-320, da 80-200 2.8, fa 50 macro, and da 50-200 but wasn't able to reproduce the problem.

One other issue I noticed, though, is that the camera turns longer lenses very very slowly. This is already being mentioned in our review
Thank you for you reply!!

I've had this problem with my K-01. I only got my K-01 yesterday, and it has done this twice already, just when trying to use it in normal circumstances. And once was outside, in bright sunlight, with the 40mm xs! I think I might return it.

Doesn't sound like that's the problem though, it's the long focus throw. How does it work with other macro lenses?

I have every existing production macro lens; which unfortunately does not include the 200. My present listing includes the; Pentax 100mm f2.8 w/r, Sigma 24mm f1.8, Pentax 35mm f2.8, Tamron 90mm f2.8, Sigma 70mm f2.8, Sigma 17-70mm, and my personal fav - the (d)FA 50mm f2.8. I've also never run into the problem.

Although while using the K-01 the focusing does take the longest (ironically) with the DFA 50, and almost as long with the Sigma 17-70. Not sure what the reason is for the 50, but for the Sigma it most likely has something to do with the aperature range - which doesn't suprise me. I usually have one of these two lens' on the camera all of the time as a type of replacement for what some would term as a basic lens.

Also looking forward to both the Sigma 150 and 180 macro's if they ever do come out. Not sure if their sdm will be of much help though

The camera clicking along just fine after some well over 3k pics; in all types of conditions. I even like it significantly better for video (with upgraded audio) than even the K-5, but have yet to compare the video to the K30. Plus zero sensor burn issues as some have noted with the K-5
