Originally posted by aaron_8 Hi Armanius, just wanted to know if you are still experiencing this problem. When you returned the lens did you replace it with a different copy of the same lens?
I get the same problem with my new 18-135 WR. Noticed it can't focus sometimes when using focal length in between 18 and 135 (both ends are fine). I usually encounter this when focusing at very far distances (perhaps infinity focus) of foliage, mountains, etc. Or sometimes when shooting against the light.
Hi Aaron-
I ended up not getting another 18-135. If I recall correctly, my problems were also with distance focusing. Not sure if it was infinity focus though It's been a while. I also recall having trouble against strong lighting.
Looks like we (and Tracy above) are one of the few people who encountered this problem. I bought my 18-135 from Amazon. Did you get yours from Amazon? Maybe you got my copy! Hope not!
I'd return it. I've been tempted to pick up another, because it's such a versatile lens. But the thought of encountering the same problem makes me think twice about.
