INTRODUCTION
The aperture ring turns clockwise to close the aperture and the engraved numerals are yellow. The wide aperture switch M/A is reversed and overlaps it. There is no model number on the back of this switch.

DESCRIPTION
VARIATION
- The focus ring formula varies as below (See Collection for explanation).
- Copies with 6 digit SN's have 6 (unmarked) half stops on the aperture ring which rotates beyond f=2; those with 7 digit SN's have 5 (unmarked) half stops on the aperture ring and rotates to f=2. (Half stop f=16 to f=11 is missing from later copies.)
NOTES
LENS PRODUCTION (∑ lenses) ∑n = 1223 Serial Numbers observed in 166 Batches covering 81,605 SN min. < ∑ lenses < 125,571 SN max.
SN min. = accumulated total of serial numbers observed within 166 batches
SN max. = accumulated total of serial numbers observed between adjacent batches of other lenses.
Letter font is "printed", round monotype with closed "4". The serial number is before the lense's name; and a comma follows the makers name.
Aperture ring has fine knurling. Focus ring formula is generally F=8/12 throughout, except sometimes ▼ F= 9/12 ▲, or ▼ ▼ F=7/12 ▲▲.
