I fitted a wide-angle screw-on lens for a Konica 8 Zoom super-8 camera on my Steinheil Cassarit 45 mm and my Voigtlander Color-Lanthar 42 mm. I got WIDE on my half-frame camera!
It wasn't pretty, but it did the job for sure!
I've been racking my brains for years trying to come up with a low budget wide-angle solution for the Pen F, which is the SLR I use the most.
I got more than I could wish for because of all the character the lens contributes to photos!
The film is a Fuji Ultramax 400 which I haven't colour corrected in any way. I increased contrast. The rest is the work of the scanning program.
I didn't find the Ghostbusters' garage. It's my brother's!
