Originally posted by E-man I just shot a few pictures with my Samsung GX-1L (*ist DL2 clone) and noticed a slight operational glitch. When I moved the on/off ring to the DOF preview position, the shutter fired! If that's the only problem the camera has, I can live with it, but should I be worried? The camera shows about 8,200 shutter actuations. I guess I'm just a little skittish after my recent experience with the *ist DL.
Check the custom settings menu, on my K100D it is under Preview Method, I'll bet yours is set to Digital Preview. Set it to Optical Preview if you just want it to stop down the lens like the DOF preview on film cameras did.
