How do you like the 35/1.4 Ai-S? I am thinking about getting one.
In my personal opinion the 35mm 1.4 in any version is an excellent and very useful lens, I have four, two Ns and Two ais, one a series 4XXXXX and the other the last run of 6XXXXX. All of them are excellent, my sharpest being the oldest, all are multicoated, the N and N.C have Thorium radioactive glass that yellows with age, but for digital cameras that is not very important. All of them are excellent from 2.0 up, at 1.4 they are sharp but will smear any bright lights badly. The 35mm 2.0 may be a better buy.
This last one is from the 6XXXXX ais at 1.4, I think you will agree with me that the detail/sharpness and contrast at 1.4 is quite nice, but strong lights/highlights are dicey, this gets much better at 2.0
