My RF 15-35mm f2.8 lens makes a squeaking noise in almost the whole range in manual focus. In auto it squeaks too, but not the whole range. Thought there might be some dust in the lens but I hardly ever change lenses when I'm out filming, they're mai...
Question! I am new to cameras and lenses. I have a Canon Rebel EOS T7 and my 18-55 mm EFS lens works and fits perfectly! But I have a 75-300 mm Canon 1.5/4.9 ft EF lens that aligns with my camera but won’t turn and lock into place. I can’t figure out...
I have had my Canon EF 75-300mm lens for several years. I have always used this lens on my Canon EOS 5D Mark IV camera body. From time to time the AF would not work. Usually, after turning the camera off or pulling the battery and reinserting the b...
I have an RF 70-200 (f/2.8) and just purchased the RF 28-70 (f/2.0). The issue is that the 28-70 at 70mm is much longer than the RF 70-200 at 70mm. The 28-70 at 70mm is comparable to the RF70-200 at 100mm. Is this inconsistency common?
I recently bought a RF 24-105 f/4 L IS USM and when it arrived I realized that I have an ef mount, the EOS R10, and when I got the RF - EF adapter, I was unable to fit the lens into it. Is there something wrong with the adapter, or can it just not go...

Hello, I am a photographer using a EF 70-200mm 2.8 L Ultrasonic and about a year ago, the lens fell onto the floor on the street while opening my bag. It still works now, however, the zoom scroll is very stiff and gets stuck at 135mm a lot of times a...
I have a RF 70-200 2,8 L IS that works well for the most part. On some photos I get blurry images that almost looks like they are taken when zooming in. This happens on different focal lengths (though I've mostly observed it on 70mm). When trying to ...
Hi everyone, I’d like to ask for some advice about my Canon EF 100-400mm f/4.5-5.6L IS II USM. A colleague of mine was using the lens recently, and I suspect that he may have tried to operate the zoom several times while the zoom tension ring was se...
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, I was wondering if anyone ran into this issue, and if so, what to do to fix it? My Canon 24-70mm F2.8 Mark II stopped working one day. At first, intermittently, I would get an error message when taking a photo. To get it to work again, I would...
I am trying to set the prefocus setting on the lens, after I set the focus and get the confirmation beep, when I turn the playback ring on the lens the camera goes into manual focus on the camera vs. bringing the focus point back to what I set. Can...
