how much better is the post 1.1 million Zuiko 50mm f/1.4 compared to other late versions of the lens, say over 1 million, or over 900K? .....
Any similar info with the MIJ 50/1.8 and the even more difficult to find MIJ 35mm f/2 would be most welcome.
There are 5 different 1.4s (i have the parts lists in front of me, I've used them for decades). Type one single coated (SC) with silver edged filter ring, type 2 is SC with black filter ring. Type 1 and 2 don't share any replacement lens elements. Type 3 says "MC" on name ring, Type 4 is also MC but does not have "MC" on name ring (you can tell by blueish, green, purple reflections in glass) this version known as NMC (perhaps as simple as No MC designation). Type 3 and 4 also do not share any replacement glass elements.
Type 5 is above 1,110,00 is of course multicoated MC. and has front element and element 2/3 factory assembled into one unit with the filter ring. Hope this explanation helps. John
