Got mine about two weeks already, some B&W shots are sharp, but the first two rolls of color slide is not as sharp as I think they should be. All the shots required slow shutter speed, about 1/5 sec, and I pressed the shutter while camera on tripod (the reason are 1 selftimer button is broke off, 2 forgot to bring shutter release cable). I guess that's the reason why the pictures are not so sharp? The color rendition is very good.
All in all, my mockba 5 is ok, need more test. Watch this thing open and close up is really a magic to me, and I almost strike a conversation with a nice lady on the sub.
