Well, the Elmarit-R 19mm is on the way, but I happened to be at the camera shop today. Glancing into the used gear department, I saw a very good looking Nikkor 18mm f/3.5 AI-S. My curiosity was piqued, I remember this as being a darn good lens once upon a time. I asked my buddy there what they would take for it. He quoted me an absurdly low price... Oh, piffle.
Now I'll be able to compare the two lenses when the Elmarit arrives.
I think it does rather well*on the A7, at least wide open and at close range. I'll have to see how it performs at greater focus distances. And, of course, I have the Nikon F to use it with if I ever feel like shooting some film. ;-)
fun fun fun ...
enjoy!
