This is a Deal Breaker for me. I am still using DSLR and it will still be a little while before I get a mirrorless camera because of budget. This news is going to make me look into getting Nikon or Sony, if when I go to a mirrorless camera, if I can'...

Resolved! Filter Question re RF 15-35mm f/2.8 L

I am one of those people who likes to use a protective filter on my lenses, especially for a lens with a hood that doesn't offer much protection, like the RF 15-35. So, do I need an ultra-thin filter (vs. regular thickness) for my 15-35 in order to a...

Terrible Rubbing Noise Inside Lens

EFS 18-135 IS USM not focusing

I’ve only had the EF-S 18-135 USM Lens for 2 years and now it won’t focus (used with 80d camera).  On AF, it won’t focus at all, so I can’t take photos.  But if I zoom on a subject and it is focused, then it will take the photo. On MF, the focus ring...
