Siluet Rapid Auto is smal enough camera, but heavy one. It's all made from metal, so back either. The camera measures about 11cm x 9.2cm x 5.5cm and need no battery for sure

. Two shutter buttons are to select 2 different programs. On the viewfinder you can see two tabs with shutter speeds: one - blue one for 1st program 1/30s-1/250s, and the second one is yellow 1/30s-1/250s again. Depending on the light, camera is choosing the appropriate shutter speed automaticly. The metal needle shows the speed selected (like on Olympus OM-2 SLR camera, if I remember correctly). Distance is estimated by symbols, you can see them on viewfinder as well. On full cock you can make 15-16 frames.
Please, don't ask me what these 2 programs mean ... maybe I was told about it, but can't remember recently ...
