Purchased lightly-used 1st generation 500mm f/4 lens. I'm not sure what "I" and "O" mean for the setting. Also, when would I use Mode 1 and/or Mode 2 (see photo)? Would love any help for these settings. Thanks!
Does anyone have a spare Super Telephoto 'mount ring tightening knob' please?? The big knurled knob that you tighten to stops the lens rotating through 360 degrees when it is on the tripod. Mine literally fell off my EF300 2.8 IS II lens whilst I was...
Hi, my EF 85mm f1.8 isn't able to auto focus – it is just jumping back and forth nervously few times a second. Manual focus works ok. Has anyone had the same issue and what could be the problem?

I have a question, I have just recently bought a used sigma 18-35mm from a retailer for my canon 80d that stated it was for Nikon however I’ve done my research and know that the lens itself supports canon and certain other cameras with an APS-C senso...
Canon 70D works fine with other lenses, but with the EF-S 55-250mm f/4-5.6 IS STM only a very blurry image. Can see and takes pictures of objects at about 1 inch distance but anything farther apart is blurry. Help!
Hi all, I have a Canon EOS M50. I just bought a multi adaptor and the EFS 24mm f2.8 lens because I want a wider angle and lower F stop. But it seems like the 24mm f 2.8 is not too different compared to the kit lens 15-45mm 3.5-6.3. 1. ) What is the ...
For those of you that have both, which one do you prefer and why?I will most likely get both but trying to prioritize. I already have the rf50 and the rf24-70 and just love what Canon is doing with the rf mounts. I would mainly be looking to do portr...
All, I was wondering if anyone here ran into this issue before, and if so what did you do to get out it of it? I accidentally tighten the tripod mount nut on my canon lens too tight now, now I can't even get it to loosen. Thanks.
I just gave away my Rebel t3i to my niece and bought an EOS RP, along with the control ring Mount Adapter so I could use my old lenses, which are a Sigma DC 18-250, and a Rokinon 2.8/14mm manual focus. When I put the Sigma on the adapter, the image i...
Hello all! So I've been wondering what kind of lenses I should start off with on a Canon. If it matters, my DSLR is a crop sensor (APS-C). I've borrowed my friend's 50mm 1.8 before and I liked it a lot but, I have a bit more money now and I want some...
I own a 200/2.8 L II USM. Bought it used in 2008, in great condition. I've used it a lot over the years. Always carried in a well-padded bag, never dropped or handled roughly.It worked normally as late as a few months ago, when I last used it before ...
Will these two accessories work together? I've already got the lenses and filters, thinking about adding some hoods. Thanks!
Hey all. I'm noticing the auto focus on my EFS 17-55 is loud. Its different than the IS which is also noticfeable, but much less. Has anyone else had trouble with loud autofocus on this lens?
Hi All, I have decided to go for the Canon 500mm F4 IS Mark I used. Cosmetically, the lens seems to be in pretty good condition minus the scratch marks on the body. Apart from that, no other blemishes that I am aware of it. That said, it is a used le...
