>>3911184You're giving us nothing to go off here anon. This is like asking what's the best vehicle to buy for $30,000 and giving no more information. You're going to get everything from point and shits, to 35mm SLRs, to rangefinders, and medium format cameras recommended if you don't give some damn guidelines. There's no good answer for 'Best $500 film camera' in a vacuum.
Buy a Bronica SQ-A. $500 will get you a body, back, lens, and hopefully waist level finder.
