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...
I have the Canon RP and Canon RF 24-240 MM IS USM. The lens won't focus on distant object or allow the shot to be taken. It used to work. I've checked the lens switches. Is it a menu function that accidentally got turned on? Or lens failure.
Hello, Canon Camera! I want to applaud you for the additions of the latest STM lens lineup of the RF16-28mm F2.8 IS STM Lens, and the RF28-70mm F2.8 IS STM Lens for those that consider themselves "pro-sumers" - photographers with a higher level of sk...

Hello: Could you please provide information on the field of view, if objective RF100 mm f/2.8L macro (on EOS R6) is placed 50 cm above the in-focus specimen to be pictured? The official answer to that question is "is 23°10" but I very much would appr...
Hello,I just ordered the RF 100mm f/2.8L Macro IS USM Lens. Does anyone use this lens without the Canon Tripod Mount Ring and Adapter? In other words, can I just screw the camera to the tripod without damaging my camera or lens?Thanks!Mike, St. Louis...
I have a Canon 300MM F:2.8 IS L series lens and the tripod mount collar is no longer rotating smoothly. This is the original EF lens and I am sure that the bearing surface has become worn. There is a plastic ring that I believe needs replacing. An...
Can someone explain to me how this works? Ef-m is a discontinued system, you can't buy anything new anymore, more or less people are getting rid of cameras and lenses to invest in new systems, but still the lenses are not that much cheaper than they ...
Hello all,R7 and RF 100-500mm owner here looking to see if there's a way to prevent the lens from automatically turning off it's stabilization in video mode when mounted on a tripod, as it seems to do. I tested this with all three IS modes, at all le...
I have read about people having issues putting filters on the Canon L100-400 that you lose your sharpness and others say they do not have a problem with it. The one thing people seem to agree on is to get a good brand of filter and B&H filters are br...
I remembering "reading somewhere" (i.e. I don't have a "quotable source") that many Canon telephoto lenses have a 'tripod detection" feature (presumably by detecting no instability) that automatically disables the IS, but is this just an urban myth? ...

Hi thereI have for a month now, been worried about my lense, since i've started to get a lot of my photos out of focus. My camera is set on eye tracking for animails at the moment. But the problem is also there, if I control the focus area myself. I ...
