Hi!
It's quite good to look back into the list!
I've sent my 28-135 for repairs just because of the problem you mention (below).
My focus ring was stiff and doing an awful metalic noise when focusing towards
infinite. I had this problem going and coming, sometimes you could hear it, some
times you didn't but at a given moment it became really annoying. I also noticed
that infinite focusing was not posible anymore. The focusing ring was blocked
before reaching this limit.
Odd enough, the noise was more acute at the long end (135) while almost
unnoticeable @28mm.
I've already sent it two times for repairs before, both because the IS didn't
work properly after a *light* schock. It's a lens you've to nurse a lot.
Nevertheless, it's a great lens and I miss it a lot!. I'm now "replacing" it
with a 50f1.8 and a 100f2.8USM and even when both of them are more than 2 stops
faster than the 28-135IS (at the same focal length), I'm getting more blurred
pictures due to camera shake. Also it's the first time that I look at the
exposure time and consider the 1/focal length rule for minimal "shake-free"
exposure. With IS, I could go as low as 1/4 with low risk of camera shake. (I
don't say I didn't get any blurred picture, but my rate of success was higher,
now I don't even try after getting some results back without IS).
Well, I hope it will be back soon :...-(
Greetings,
Gerard.
