This is very tempting Keith, I have a 35mm and I have a 50mm but this covers both in that range. Not sure if a zoom that covers both would be good for me rather than the two primes. This is a FX lens correct. I did look at your link this time haha.
I also have the Sigma 105 that I never really use lol that I probably could get rid of even though thats 1:1 rather than 1:2.
