Hi. I use a an old Pentax film camera with a 50mm lens, which I like quite a lot. But I'm thinking to go digital and I really can't find something equivalent in the digital world. All I want is a long-ish lens, between 50 and 70mm (so things don't come out tiny in the picture), and control over focus, aperture, and shutter speed. No menues, no previews no bull****. Is there a digital camera that can do this?
