So I have the original EF 100-400 4.5-5.6 L IS USM lens, and already know that with the EF 2x Extender I can’t use autofocus because the maximum aperture is f/9. Does anyone know of a third party option that would still allow autofocus? The 400mm f/2...

Hi there - I am hoping someone out there can help me with a problem I had Saturday night shooting an event. My 70-200 lens on my r6 Mark II body would not autofocus whatsoever. It wasn't even trying to focus. The orange box was there indicating it wa...
Hello!My AF feature stopped working on my lens and ever since I turned 50, I absolutely rely on it to nail focus. (The whole glasses on to see camera buttons, glasses off to look through lens scenario drives me crazy, but I digress). Steps I've taken...
Hello to all Shutter Nutters, I updated my FR24-105mm F4 L IS USM lens today and as always, it was a stroll in the park, with no hassles at all. So I'm now reminding all RF 24-105mm F4 L IS USM lens owners, that have not yet updated the firmware on...
Hi All,I use a Canon EF 24-105mm f/4 L with a Canon R6 and a Canon EF-RF adapter. For the second time in six months, the diaphragm has failed (Error 01). Does anyone have an idea why this might be happening so often? Is it possible that shooting HDR ...

Hi, does the canon lense 100-40mm f4.-5.6L Is II USM fits on a canon R7? Thank you
In looking to find service for a EF 500 f4, I see Canon is no longer offering service for this lens. Can anyone direct me to someone that can do repairs on this lens? The manual focus ring is very lose and I wanted to get it checked. Don't use it muc...
Canon have got a lot of flak from users who, for various reasons, prefer 3rd Party lenses over the Canon native ones. That could be performance, cost or pure bias (believe it or not), or because they felt the release of Canon native lenses is too sl...
The topic continues to show up and we always get a couple of responses. I'm hoping this thread will build a consensus from the members that frequent the community to assist guests that come to the site looking for assistance. I do use a high quality ...
