I haven't gone to an AF Nikkor lens because I don't like AF, and the AF Nikon 85 1.8 I had, while good, was not spectacular. This Elmarit will be a big improvement.
Every slow lens is too sharp, You need a fast lens w/ great bokeh for portraits, but not all fast lenses make good portraits. Sharp portraits are not a good thing, especially at middle age and beyond. I might try a filter some time Sirius. Others have recommended it. One of these lenses will work though, I'm sure.
I may end up shooting the Elmarit on the Leicaflex Standard that's hiding behind those two lenses in the photo though. The viewfinder on the 'flex is unbelievably bright and big! It's like looking through a big picture window, and it's almost as bright as the actual scene. I don't like carrying big, heavy gear, which is why I sold my old Leicaflex, but the sound of that Leicaflex shutter and it's viewfinder are difficult to ignore.
