A discussion about the design and actual appearance/dimensions of these lenses has filled up the "soft lens sales data" thread in the last few days. As a definitive list, description and images of the many types do not appear to have posted before, I thought it might be a good idea to start a separate thread where we can gradually build up documentation and perhaps equate with serial numbers? I don't know whether it is possible/advisable to move some data from that thread to this one?
One thing is quite certain, the old version of quadrant notches and rear turn did continue parallel with the introduction of the "smart" front barrel turn type.
