Disassembling and removing lens unit procedure had been done with desperate concentration and doing on lens unit to clean lens glass and iris blades in addition to removing out all the mechanical shutter unit with slow governor and slow timer leading to 60 gr weight reduction.
Physical positioning of helicoid construction makes it possible to reproduce all the barrel alive on Sony E-mount this time. The weight including new bayonet would come to be about 200 gr in total, helicoid outer lace, guiding outer ring, iris ring and shutter speed ring and front decorating ring are all made of brass material as a matter of fact.
Hexanon 45mm/1.6 on Sony E-mount would be regarded as if it was easily removed and just put on the mount without any difficulty. No complicated scaling and calculation were not required? No precise processing by technique is necessary?
Anyway, straight helicoid system and full barrel reproductions would be attained this time.
I'm looking forward to shooting photos with this lens, trial fitting test has revealed fine performance already, to tell the truth.
5 group 7 element lens construction will exert a great performance with superb transparencies!
