nf3996 Posted July 21, 2022 Share #1 Â Posted July 21, 2022 Advertisement (gone after registration) I've recently bought a 2.8cm f/5.6 Summaron lens - the 1950s LTM version - but I can't see a serial number on it anywhere. It's not on the front of the lens nor is it on the back. Do these lenses have visible serial numbers, or are they hidden somewhere inside?

MarkP Posted July 21, 2022 Share #2  Posted July 21, 2022 Can you see it engraved on the black ring that secures the back element? Link to post Share on other sites More sharing options...

nf3996 Posted July 21, 2022 Author Share #4 Â Posted July 21, 2022 Thank you. Yes, i've now found it on the black ring around the rear element. Very difficult to see - at least with my eyesight! Alan 1 Link to post Share on other sites More sharing options...
