Old camera lenses are awesome. I've got some steel and glass rokkors that are beautiful. They render in such a wonderful way too, so painterly. They have thorium in the glass! Not enough to be sketchy to use but something that obviously isn't done anymore. Bonus points that they can be fixed with a hammer.
Old camera stuff in general is subjectively cooler. The leaf shutters in my 4x5 lenses are incredible little machines. Film in general is cooler than whatever sensor the latest and greatest has. Actual bits of silver suspended in emulsion, with colour filters and dye couplers that react in development. There's a great three part video on YouTube breaking down Kodak's manufacturing process. It's mind boggling that stuff even works. Ohhhh and actually darkroom optical prints! Don't get me started there!
I'm going to develop some rolls I think. Got me in the mood.
Rokkors here as well! I still shoot them mostly with film, but I'm tempted to get an adapter for my Fuji. Don't love the conversions though, stuck in my ways with focal lengths and it's just weird when a 28 becomes a 42!
