Antonio, great images and very nice colors.
Ray, I found similarly Nikkor-S 35mm 1.4 for a good price and wondering if there is a 50-55mm match up... I guess 58mm 1.4 is the match, but much more then I paid for the 35mm The colors were excellent on 35mm but the flare was bad. I tried it with the OM 50mm 1.2 and it was even worse with flare... It is due to coatings of that time. I don't know if you had a chance to try in sunny outdoors...
