RF 24-105 mm F4 L IS USM lens making audible noises during AF

Hi, I am new here as well as a new Canon camera/lens owner. I got a Canon EOS R6 together with a 24-105 RF lens a few weeks ago. About a week ago, I started to notice a fairly audible noise when using the camera with the 24-105. I think the noise is...

Wondering how to fix a lens that won't communicate with the camera

Hi! I'm a hobbyist photographer with a Canon Rebel T6 and a regular 18-55mm Canon lens. I was trying to clean the inside of the lens, so I did something that proved to be dumb: I unscrewed the back of my lens and attempted to pry the cover off, think...

Fast vs Slow Lenses on Mirrorless

Since some of Canon's RF lenses are slower than most typical EF lenses and I know it is said that that's not an issue since the mirrorless camera sensors are better able to handle higher ISOs but I have a question about that. Am I misinformed in thin...

Repair needed

I recently dropped my 24-70mmL lens. The glass is fine, but the barrel has a chip in it. It's extremely difficult to attach/detach the lens from the body. Canon does not repair this model. Any reccomendations on where to have this repaired? TIA!

Sigma 105mm F2.8 EX DG HSM will not spin to lock in Canon SL2

Hi all, Purchsed a used Sigma 105mm F2.8 EX DG HSM off eBay. Research says that it should fit the Canon SL2. However, the lens will not turn to lock in. It does fit snug into the mount, just doesn't turn. On inspection the lens is super clean and...

Canon 24-70mm lens won't go down to 24mm

Hello everyone, I have a Canon 24-70mm lens first generation, that I hadn't used in almost a year. I went to use it this past weekend, and the lens got to about 35mm and did not want to down any further. I gently zoomed in and out and got it to open ...

Lens Diffraction vs Image Quality

While recently attempting some panoramic photography, I was using f-numbers of f/11 to f/16 to increase the DOF. Later I wondered whether light diffraction was spoiling some of the image quality. My equipment was a 7DII and Canon 16-35 mm IS USM f/4 ...
