I have the original version and never thought much about this lens. It’s now the most valuable M lens in my possession. Weird. Anyway I shot with it on my M10M. The lack of distortion is remarkable. I framed this shot for the lines and geometry. Look at the upper right corner. Straight lines. I like this lens because it makes a digital shot more film like I suppose because of the low contrast. I wouldn’t want a modern version with improvements if that was lost.
