AF stops working, camera stops recognizing the lens
3 August 2010
Summary: Looks and feels good, great zoom. However, issue is that the auto focus stops working, and the only way to reset it is to turn off the camera, and reset the lens. I don't know if this is an issue with the Tamron lenses, or I got a bad lens. Also, during the shoot camera stops recognizing the lens all together. dismounting and mounting the lens back would fix the problem for some more shots. Returned the lens.
Summary: I read several reviews before purchasing this lens. They were all positive so I bought the lens to get a little more reach than the 18-135MM Nikon that I normally have on my camera. It appears to be well made, was fairly light for the range and looked to be just what I wanted. After about a dozen shots the Auto-focus quit working and I had to use the manual focus.
Summary: I initially liked this lens and it looked like it was going to stay with my Canon 500D. I really liked the compactness and all-in-one portability. But after comparing the picture quality of this lens with my Canon 55-250 IS, the softness in quality was quite noticeable indeed. Like other reviewers, the thing that bothered me as well was the lens creep. I tried the rubber band trick but eventually took it off since it was not nice to look at.
Summary: Purchased this lens as a all around replacement for the kit 18-55mm. Intially it looked pretty good but when I started shooting lighter colored areas I discovered dust specks in the photos. I took a really close look and sure enough under the front lens were numerous (at least four I could see) specks of dust.
Summary: I thought this would be the ideal everyday/vacation lens for my Alpha 100, and optically it was fine. Focusing, however, was extremely slow and inacurate most of the time. I'd often have to press the shutter release half way down 3 to 5 times to get it to focus, each time it got a little closer till it was finally right. When zoomed in it wouldn't focus at all, I had to go wide angle, focus, and then zoom in again to take the shot.
