So, I cut my teeth as a teen on the K1000. About 8 years ago, I got back into photography and bought a K200D, and way too many lenses (including old manual focus glass). I shoot mainly macros of native flowers, and often handheld, as I do this out in the field rather than just for photographic sake. While my old camera is fine, a couple things have bothered me. First, I now have a tremor due to chemotherapy a few years back, so slightly better anti-shake should be a plus. Second, autofocus is slow and clunky. Third, I often crop, and the increased resolution should be a plus. And, for what it's worth, the bug just bit. So, I just upgraded to a used (@ 2200 actuations) K-3. Now, I have to learn to use it

. Plus, there was so much that I hadn't mastered on the more basic entry-level camera. Frankly this is overkill. But, I'm going with it.
I have a range of glass, but most often shoot handheld macros with either the 50, or more often, the 100 mm macro lens (D FA 100). Thinking of adding a cheap used portrait length for taking more shots of the kids, but the fast 50 or 55-300 zoom does most. But, can you ever have too many toys? OK, we know that you can, but denial is not just a river.
Bought the eBook. Wish there'd have been one for the K200.
