LENS PRODUCTION (∑ lenses) ∑n = 930 Serial Numbers observed in 60 batches covering 32,771 SN min. < ∑ lenses < 45,853 SN max.
SN min. = accumulated total of serial numbers observed within 60 batches
SN max. = accumulated total of serial numbers observed between adjacent batches of other lenses.
Three styles: ▼ Aperture ring finely knurled and lacking half-stop between f=16 and f=22, round lettering. Focus ring has 3 screws; formula is 11/12. Numeral four is closed (4). ▲
▼ ▼ Focus ring formula is 10/12. Numeral four is closed (4). ▲▲
