Hi,
Please help me if you use the EOS 28-135 IS lense. Do I have to buy the
slim polar filter because of the vignetting? Earlier I use an EOS 28-105
and I have problems with the Hama 7 mm  thick polar filter.
Thanks in advance.
Bye,

Well, since you have vignetting at 28mm with the 28-105 you will have them 
with the 28-135 at the 28mm end. 28mm is 28mm

I use a slim polarizing filter on my 28-135, I think 3mm, and have no 
noticable vignetting.

28mm with a 58mm filter size is most decidedly not 28mm with a 72mm filter 
size.  Unless the pola filter is stacked with a thick UV, then you probably 
won't have vignetting.  I don't, with a Hoya UV and standard polarizer.  But 
a wide angle rubber lens hood does vignette with this combination.
