Ron Wisner once told me to add an orange filter when using the rear cell only. If I remember correctly it reduces chromatic aberrations

Congratulations!
Use it in good health!

Will do. Its as pretty as my Extar 14in. Kinda wish it had an old school shutter.

Matched Pair Sinar Norma 300mm f5.6 chrome Symmars 5x7 TLR Norma camera great for portraiture. 4x5 Reducing Backs and Reflex Viewfinder make it true TLR. I'm leaving this camera set up in the studio.

New canvas background from David Maheu like it "Tim Kelly Gold Plaster"

Nice set up

Have fun!

There's also "focus shift" ... sometimes convertible lenses can be sort of tricky.. ic-racer wasn't talking about a convertible lens he said NON convertible lens ..

Excellent, my uneducated guess is that your 500mm lens probably takes around 24-25" ...

it's not found on their new re-designed website but thanks to mr peabody and his pet boy sherman
here's some info on their "vintage" lenses like yours
https://web.archive.org/web/20050303...tics.com/info/
you can search your serial number to find out the age
you can get tips and tricks old brochures
white papers, optical mechanics. .. lots of fun stuff
not sure if they have these things on their new website. ... couldn't find them..

good luck!
