The lens arrived today. A 1,210mm Nikon Apo-Nikkor. This is a monster of a lens, weighing in at 8.5 pounds. It’s looking like my front bellows frame is going to need some modification to fit this thing. Not a problem. Today I’m working on the spring-back I’ll post some p
hotos later.

Wow! That’s a nice piece of glass! How much does something like that cost? And what was it originally used for?
This lens was $800 on Ebay. I believe that it was used for enlarging. Not too much info out there .
How much this’s Len ? May be I ‘ll Got It..
