Hello! I just picked up a used Sigma 24-70 f/2.8 DG OS lens (the newest 24-70 version, 2019 I think?) and it works just fine on manual focus, but the AF is not working. It was giving me an Err 01 code, and so I researched and found that the most comm...

Hi. How harmful is using SERVO-mode for gears in the lens? I shoot on R5, but the fleet of optics is EF-L (24-70). I've heard from photographers I know that using EF lenses with SERVO-focus leads to rapid wear of the lens mechanism parts. Is it so?

Wasted over an hour trying to register this lens. It can't be found under either individual or kit. I can find the lens itself, and I can find product support, etc. I just can't register the thing. Canon has the absolutely worst registration page...
I'm thinking about buying a EF 300mm lense but I recently saw that service dates are expected to end in 2028. Would anyone have any concern about buying one because of this? I think these are well built and maybe independent shops could service them ...
I have a EF 70-200mm f/2.8L IS II USM lens that I purchased used. I use it on a 5D Mark IV. I have noticed that it is a bit soft and looked into making some adjustments, with the help of Reikan FoCal Pro. In doing so, I saw that the lens was repor...
