Question about SP AF 150-600mm f/5-6.3 Di VC USD G2, Canon EF - 542229

I photographed with this lens for a long time together with my EOS 650D (not 600D). Everything worked without any problems.

Hello if you want to test with my lens and your camera get in touch 076 378 54 32 Franz

I have a 550d. Works.

In terms of the mount, it should fit. The 600D has an EF-S bayonet, which is compatible with Canon EF lenses. As long as that fits, the lens should actually work.
EF lenses fit on an EF-S bayonet, but EF-S lenses do not fit on an EF bayonet.
So nothing should stand in the way of your combination ☺️
I hope I was able to help!
