Absolutly GREAT article. Wow was that a joy to read and look at.
The lens certainly has its uses...for me, this lens didn't work out. I would much rather carry around my FD 35mm f/2 S.C.C. and adapter when I travel - it's more fun and provides more optical character. (God that sounds so hipster, but it's true.) For me - looking for a smaller 35mm - I thought it would be a great lens for the EOS R when I travel. It wasn't for me and I didn't like using it at all nor did I feel I was happy with the majority of the photos. Every lens has its sweet spot, as I pointed out. This lens with its macro ability is very unique. But I fear that providing this macro capability may have impacted its rendering for general purpose photography? I really don't know.
