I use two K-30 bodies. I only have to remember the controls for one camera model. If it's a shortish walk I carry both. For me the advantage of two bodies is not redundancy but to avoid having to change lenses when I might miss a shot and/or get dust in the camera.
I usually use a wide angle (12-24) on one and a tele on the other, but sometimes other combinations, eg
- Tamron 18-250 on one and 35, 50 or 100 on the other. This is a good walkaround combination.
- Pentax 55-300 on one and 100 on the other (for flowers and macro)
- 55-300 on one and 170-500 on the other, when birding. The 55-300 is easier to use for qucik shots when birds are flitting around closer by. The 170-500 is better for more reach, and when I have a clear view (e.g. at a hide).
I notice that the responses in this thread suggest that people with two different bodies generally put a longer lens on the one with the higher mp count. I guess that, paradoxically, longer tele shots are more often cropped. (That is my experience too. Even a bird shot at 500mm usually requires some cropping, whereas wide angle landscapes etc often don't.)

There might be a correlation between serious photography and divorce rates! Or to put it another way, some people love their Takumars more than their spouse!
Norm's solution of marrying a serious photographer isn't available to all of us.
