I wish I could afford it at the moment. I've been hoping to get a full-frame body for quite some time, but grad school has put a substantial damper on my photography acquisitions.
Are you just paring back, or looking to upgrade? It seems a lot of us Canon shooters are looking at that EOS R system.
Looking to swap out my lenses to the 16-35 2.8, and the 70-200 2.8. I think the 70-200 will be a little more versatile than the 135, and the 16-35 is a little better quality and faster for shooting video and in low light.
The 70-200 f/2.8L II USM is my favorite lens so far. The version 3 is supposed to be a bit sharper, but the v2 is already plenty sharp. It was the last lens I got before going back to school.
Wide lenses are fun. That 16-35 looks nice. The 11-24 they put out is amazing, but the price tag is pretty crazy too.
Good luck with the gear acquisitions!
