i love mine. nothing renders like it. to me it highlights the art of lens making in that its character changes as you change the aperture. you make the decision on the look you want to achieve, and if you understand this lens and execute, you get what you want. soooo very different from the modern--and imo soooo boring--'knife sharp at any aperture'. why have different apertures if the look is always the same? i think this lens is misunderstood because the art of photography is misunderstood.
