Ah, so I thought Canon had changed mounts... yes, and when I was shooting crop sensor Nikon I couldn't find anything wider than my 18-55 kit, not that I could afford in any case, and not a prime.
Rumors have it that Nikon will finally replace the F mount lens with a new line for full frame mirrorless... which I would really want. I guess Nikon would come out with an adaptor to let me keep all my current glass!?!
Should have mentioned... I like your photo. I love silhouettes
