Rear Lens Cap for 150mm f5.6 Symmar-S

[Zimberoff]

Howdy,

Owing to the fact that I don't have an accurate millimeter ruler, can anyone tell me if the lens cap diameter of a Schneider-Kreuznach 150mm Symmar-S is 39mm or 40.5mm? I'm have to buy a replacement cap.

Schneider says the rear mount diameter is 40.5. That's the size for a slip-on cap.

Real world measurement on mine is 40.45 mm. I have a 3rd party 40 mm slip-on cap that works well

I thank-you, gentlemen. The members of this forum are truly a font of knowledge— and kind enough to share it.
