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...
I prepare better quality photo gear for sale for the local thrift store that supports our non-profit hospice and have a bag of Canon crop lens gear on my bench. I'm a Canon full frame DSLR owner with a bag of L lenses, so very familiar with normal op...
I bought a used Canon 200mm f/2.8l ii usm lens very recently for my EOS RP camera (already that the Canon adapter) from an online retailer with excellent return policy. My question is about internal spots visually evident by looking through the lens....
I am getting a black spot on the right side of my photos when using my RF 100-500 at high fstop. Any ideas? If I take it down to f22 or lower it seems to go away. I get the same result with R1 and R6 Mark II.The attached photo was shot at ISO 5000...
I got this from CPS yesterday. Info for the ones of us that have this lens. "Your EF 70-200 2.8L IS II USM will no longer be eligible for service after 6/30/2025. In appreciation of your continued loyalty, our expert sales team is standing by to help...
Hi....I've thoroughly confused myself, which is quite common. Looking at an R10, it is APS-C. EF-S lenses were made for APS-C as well. Would this camera crop those lenses too? Or would that be just be the full frame R series bodies that would crop to...
I have an RF 28mm f2.8 STM lens which I love for its small size and weight. My concern is that I offten refit the lens cap while the camera (R5 MK2) is still powered on and the focus motor 'fights' agains the pressure of re-fitting the lens cap. The ...
I own a C80 which I love, but I do not like the RF lens stabilization for video. Plain and simple: RF lens stabilization is too jerky. This applies to all of the RF lenses I've used so far which include the 24-70mm f/2.8 L IS, 70-200mm f/2.8 L IS, ...
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?
I have an older Canon 1000D and am considering purchasing a 90d camera. I have a number of lenses for my 1000D namely 1)Tamron 18-270 f/3.5-6.3 Piezo Drive 2)Tokina ATX-Pro SD 11-16 F2.8 (IF) DX . I would like to know are the lenses compatible with t...
I have a 24-70 f/2.8 EF lens on my C70 Cinema camera using a Canon EOS EF - RF adapter. The autofocus causes substantial noise. But when I put the lens and adapter on my R10, there’s no noise at all. The research I’ve done thus far suggests the adapt...
A friend of mine was lucky enough to have received her Canon RF 200-800mm lens that she had ordered in Nov. 2023. She has encountered an issue with the lens design. The new lens does not appear to allow use of a filter while the lens hood is in pl...
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 ...
