Tesla is not only a scientist, but also a mesure of magnetic field strength.
Someone made a focusing mechanism for this kind of lenses, and I think there is a 3d model for printing somewhere. You can search "kodaflex" on youtube and maybe you will find more info about it.
It's a lens from an old point and shoot film camera called pleomax pleo 15se, and it also works as a almost fine macro adapter for my phone's camera.
First grade stuff for average Icelandic buddy
Bless the soul of the person he was looking at
It can do print worthy images, but i plan to use it as intended(at least I think so), just to capture moments with friends and things that I need to remember. Also, speaking of an old canon DSLRs, I currently have a canon eos d60 from 2002, it's only 6 MP, but it works well in 2024
Specswise it has Vario-tessar(my favorite optical scheme, but with zoom capabilities), equiv. 32-128mm, f/2.8-5.8, OIS 1/2.5" CCD sensor(good in low light) 8.1MP, but actually not, cos max resolution is 3264x2448, and by doing simple calculations I get 7.99MP ISO 100-3200 And it's fun to use.
