I had not used my Pentax K10D for over a year. The Olympus E-P2 does everything I need, taking less space and weight. The only reason why I still considered using the Pentax was to enjoy my beloved Zeiss Planar 85/1.4, which I had converted from C/Y to M42 mount.
So recently I took the Pentax and the Zeiss out of the closet and took them on a weekend family trip. The K10D has excellent ergonomics and it was nice to feel it in my hands again. But after a while I became aware of the reasons why I am now enjoying a mirrorless camera system so much: small size/weight combined with a good electronic viewfinder with large image size and the possibility of magnification and live histogram display.
But the Zeiss Planar continues to produce beautiful images on the K10D. And yes, a 5 year old digital camera (with a decent sensor) is able to create images as good as last week’s model. It might have fewer pixels, no video mode, no live view, painfully slow frame rate, and awful noise above 400 ISO. But it takes nice pictures if you point it in the right direction and set the aperture properly. What else is really necessary?...
