An OMG (OM20) has a built in hotshoe, uses currently available batteries, and has both aperature preferred automatic and built in manual exposure capability. It also tends to sell for a reasonable price.Originally Posted by MattCarey
It isn't quite as robust as an OM1 and doesn't offer as many system camera features (interchangeable screens etc.) nor does it have mirror lock up but it is a very functional camera that all the OM lenses fit.
