Originally posted by Rondec The only "bad" Pentax camera I've used was the K7. And it wasn't bad in terms of usability, but just the sensor was pretty poor, with not great dynamic range and so so high iso performance. I was so pleased when Pentax left their partnership with Samsung to go back to using Sony sensors in the Kx and K5.
The K-7 is the camera I got a year ago when I got into photography (and that I still have). Honestly, the ergonomics (the body has been used in all other APS-C flagships, right?) and ruggedness are 11/10, the viewfinder is very nice, everything except for the sensor is good to great. The problem is that the shadow detail is very, very poor (very grainy shadows are all too common), and ISO 800 is already noisier than a heavy metal concert.
I also tried a Pentax ME that I got last week, but it turned out, after putting the roll in, that the light meter was stuck in "OVER" so I only shot one roll at the mechanical setting, using the phone as meter... let's see how the negatives come back. Can't comment on how good it was, but I had so much fun rediscovering film after my childhood days with disposable cameras and my parents' Zenit. The viewfinder is enormous and the camera itself is adorably compact and comfortable to use.
