I'm going to be the dumb guy here and ask is there any real major differences between the 7 and 8 element version optically? IIRC the earlier version is more desirable? Or do I have it the wrong way around? I never got what the big deal was over the Takumar 50/1.4. I have a M50/1.4 and its very, very good for portraits with delicious smooth bokeh. From some sources, I heard the takumar is slightly softer. So what's the deal with this lens?
