Canon states they are colored this way to keep the flourite based elements from overheating in hot environments. So does this mean they perform better than Nikon, Sigma, et. al.? Or have the other vendors solved this "issue?" NASA even uses Nikon!!
I got a brand new canon eos r6 and lenses to go along with it but one of my lenses won’t go on while the other works fine. How can I get it on? It’s the canon zoom lens ef 75-300mm 1:4-5.6
Hello. I use a Canon EOS Rebel T7 and I use a Canon EF 75-300mm and 18-55mm. Recently, my camera starting making a shaking noise. It was only yesterday when the focus ring started to move very slowly, as if you were moving it with AF on, but AF wasn'...
I have a 24-105mm f/4L series I that is front focusing badly, but only at the wide angle end. Above about 50mm, focus seems accurate but at 24mm, what should be infinity instead gives me in the 3-5 meter range. It slowly gets better as I zoom out.I’v...
For whatever reason my EF 50mm f/1.4 will no longer open wider than 2.8 or close more than f/8. I currently have the lens mounted on my 5d mk iv. The problem doesn’t replicate its self on my 7d mkii, or my 70d.Can anyone out there help me identify & ...
Recently purchased 5D iii my 70-200mm will not AF. I've used the lens on Rebel T3i with no issues. I have checked the settings on the lens and have tried both distances (i.e. 1.2 and 2.5). Since the lens works perfectly with the T3i right now it d...
To the person with the 70D canon and the Sigma150 600 lens. How did it go with that?
Hello-I have an old film SLR camera (Canon EOS Elan 7E) with a handful of Canon EF lenses - got when my now college age child was born. Rather than have the lenses collecting dust in my closet, I was considering getting a Canon DSLR body but I don't...
Hello all,I'm one of those people who worries about accidently damaging my camera gear. I just purchased an EOS R with the 24-105 L series lens and I was curious how easy it is to scratch? Should I be worried about scratching the lens when replacin...
Hi,My neighbor bought a Canon Rebel EOS T4i used camera. The only lens that came with the camera is a 500mm Ultimax.I've tried to take pictures with this lens and it won't focus. You can take a picture with it, but it's very blurry. No matter what I ...
Hi. New here. I've had a 70D for a couple of years now, and I will freely admit this is too much camera for me. It requires too much thinking and remembering on my end. That said, I can typically do fine with it. However, I've run into an issue that ...

Came across a review for the Tamron 18 - 400mm f/3.5 - 6.3. With a range that wide, it seems it could be an "all-the-time" lens, pretty much eliminating the need for multiple lenses. My primary focus birds and wildlife, thus the desire for the large...
The Eos 30D I purchased used came with an older 75-300mm lens. Reviews seem to rate the newer 70-300mm w/ IS as a much better lens. But how much better? Also, the 70-300 is full frame - would that work with my older 30D?
There has been a lot of interest in using old film camera lenses on new DSLR or mirrorless cameras. Although this isn't a comparison of that it is an old vs new example. Neither is right or wrong just the way it is. I won't say which is which so the ...
