Originally posted by LesDMess Most all cameras that I am aware of have the ability to multiexpose a frame. You first make sure that the film slack is taken up with the rewind lever, push the film release - as if to rewind, then cock the shutter and fire. I have a few other manual cameras that have a dedicated multiexpose lever so instead of using the film release, you simply move that lever. This is still the same number of steps.
The difference with the LX is that you don't ever have to take up the film slack because it's mechanism holds the film steady. Because of this, you can actually rewind or advance the film using the frame counter and accurately multiexpose any frame yo want.
Yup, it's nifty and quite useful to watch the frame counter tick backwards. I merely meant it's certainly more fiddly than some.
My Konica T3 has a dedicated lever that allows multiple exposures for as long you like - easy as pie.
**edit - I say more fiddly above because better note-taking is in order mostly due to the fact that using the rewind button on most cameras doesn't stop the frame counter, which will advance forward normally. If you do this often enough you'll run out of room on most frame-counters. There's also the issue that if exposing using the rewind button you run a risk of the frame shifting becase the sprocket tension is released in that case, whilst the type that have a lever merely use a sort of cam mechanism to allow the shutter cock without engaging the film advance but still keeping locked tension on the sprockets.
What the LX *does* give you in spades is the ability to decide later "hey I think I'd like frame number 9 [for instance] to be double-exposure" when you're on frame 23. You can quite easily tick back to that frame. I normally go 1 or 2 before it and then blank advance/expose (lens cap on at 1/1000 shutter) back up to the frame I want, expose it again how I like, then shoot blank frames once more to go all the way back to where I left off on the roll. Fiddly, but quite unique and extremely handy.
