I've been a Canon shooter for about 8 years. I have a lot of L glass and a 5D4. There is just something about the A7R ii that I can't resist, so I bought it (again) last week. I bought it with the 50 f/1.8 and sold my 35L since I now have the 35 f/2 IS. Now I'm debating returning the 50 1.8 and getting the Sigma 35 Art with the MC-11 adapter. This got me thinking about swapping all my Canon L primes for Sigma Arts (over time) Is there anyone else running with such a setup? Looking for thoughts/advice.
