You typical SLR. I got one almost identical, but my flash quit working for some reason...
My grandfather has one too. It IS identical to mine, but he has many other lenses. He has one that's about 600mm. It's amazing how huge it is, especially when you compare it to my Panasonic digicam which has a 432mm zoom but is smaller than our standard lenses.
Did you try pulling up on the rewinder knob?
And yes, those flashes are quite powerful. Not a good idea to flash it too close I originally had hoped to use that pictured flash on my Panasonic. But unfortunetly, it's dead as I mentioned...
Dude, I'm not going to type a step by step guide on how to use it But yes, any standard 35mm file should work.
