Canon EOS Elan along with an F-801 from my dad. $10! I'll need some advice though

I'm not planning to buy any glass for it, since I'm way too cheap to get non-Nikon stuff for something that only amounts to a niche I'd explore. So I'll just borrow some kid's 50mm and go shooting I suppose. Read about EF-S and EF not being compatible and whatnot, so should have that already figured out.

What's some good film brands? I like saturated Velvia-ish...answered my own question. Although I'd definitely need some neutral shades for portraits. If you have basic film advice let me know.

And by the way, how dangerous are 2CR5s?
