First, Thank You.
I was going to say anything that starts with a FL under 24mm.
I don't know how many attempts I've made long ago using "Whatever" book, learning 35mm photography with a 50mm. For some reason, I seem to hate 50's. A 35mm prime made everything more in perspective. I later acquired a 28, 24's and recently, an old 20mm.
I have the old 18-35/nikkor and a tokina 17-35, AF, but what I'm mired in at the moment, an all manual focus lens kit. A 16mp camera that is quite forgiving in noise reduction that is also fun with old, 30-40 year old primes, I don't necessitate a Df in needing a $2K prime.
If you take off the filter the DX 12-24 nikkor is quite usable @ 16mm & above but it's another confounded Af lens.
