I have the Pentax istDL and the K100D i bought both cameras new and still use them they all work fine with Pentax screw drive autofocus lenses. The green dot is fine for manuel focus.
Funny that you give the Canon crop factor of x1.6 then do the maths at the correct x1.5 that these sensors have. 😊 I have a K-m 10mp model.. and have found results to be stunning with the 50mm SMC A f1.7.. the 80-200 f4.5-5.6 film era kit lens.. and the 70-210 SMC A f4. I also have two 18-55mm DA kit lenses. One very crisp.. the other suffers from blistering of the lens element coatings so rather soft contrast with spreading highlights. My K-m is very much like the K-r but with the CCD sensor.. so no live view and no red viewfinder illuminated focus area confirmation points. Just bought a K100D for £20 so looking forward to trying it with AI upscaling. Maybe shoot and crop to square 2000x2000 then use free AI scaling software at x2 to stay within the 4k limit imposed by most free versions. Great advantage of the CCD models is their use of AA batteries.
