Hello,I've bought a used CANON EF 28-300 3.5/5.6L IS mentioned as "like new", and I have a 6D Mark2.After only 3 times, I got this message : "Err 01. Communications between the camera and lens is faulty. Clean the lens contact."Impossible to use the ...
I was wondering if Cannon was looking at making the new RF75-300 F4-5.6 as a “L” F2.8 IS USM lens. I do a lot of hockey shoots, and the lighting at some of the hockey rinks is not that good. I currently use the EF70-200 F2.8 L IS III USM lens, would ...
Can the Canon EOS R3 camera body and the Canon RF 200-800mm lens be focus adjusted (tuned) by Canon? My current lens and camera combo has problems maintaining sharp focus "lock on" . When using my R3 with the RF200-500 lens or my EF 500mm lens the fo...
I have Canon R5 Mark ii and the moment i attach my RF 5.2mm 3D 180 lens, the camera greys out all the HDR shooting modes.I usually shoot raw light, but for a studio recording with controlled light i would prefer shooting straight HDR PQ for faster wo...
Four’ish years usually on a tripod in a climate controlled studio. Maybe ten family trips. I’m guessing the warp ring is from a couple of days stored in a Pelican in the car on hot days but know idea. Functionality not affected and I have no idea whe...

Good Morning, Yes I am embracing digital cameras and loving it. I made my choice and got an R7. I know I have a lot of EF glass, but one RF lens that intrigues me is the 24-240. Seems to be a really decent lens from what I've read thus far. And tha...
Hi all, I have an opportunity to use RF 35mm F1.4L VCM together with my EOS R10. It would seem that they should be compatible, however, it seems like there is some issue with this combination. When I start the camera, it's almost like the lens fails ...
EOS RP with RF 70-200mm F2.8 L IS USM for astro I am evaluating the RF 70-200mm F2.8 lens for astro. So far I am reasonably impressed with some preliminary results (comparing to a 135 mm Rokinon prime lens). I have a question about a bright star flar...

All, I was in a camera store last week and the rep that I was talking to mentioned using a APS-C lens with a full frame camera. With a Canon you are losing 60% of your pixels or only using 40 % of your pixels. Why would you want to use that combinati...
Hi,I've seen some older posts on the following issue, but never has there been a solid answer or the problem was (wrongly) accused of being due to an inferior tripod used. I've come across this problem with the RF100-500 and it's quite a dealbreaker ...
Hello! Does anyone know why the Canon 28-70mm f/2 does not show at all on their refurbished lenses page? If it ever does, what’s the refurbished price? Thanks!
