If you have a film camera and it doesn't support TTL the most convenient kind of flash to use is one that has an auto mode that uses the sensor on the flash. You can buy old flashes that have this feature and cheap but if you want a new one you're out of luck. Cheap new flashes like the Godox or Younguo are quite good except that they don't have this feature. The only new flash I found that has this feature is the Nikon SB-5000 which is way too expensive to buy if you have something like a Pentax KX or Nikon FM etc..
