I measured 120mm F1 on that projection lens and mounted it on my camera. The plates I shot with it are on eBay ( eBay.mhaustria.com ) and I give one of them away to my patreon supporters ( patreon.mhaustria.com ). That project was lots of fun ( https://youtu.be/dXMn61ZcQjo ) #lensporn #tintype #ambrotype #analogphotography #largeformatphotography #handmade #wetplate #nassplatte #mhaustria #keepfilmalive
