I think your your best bet would be a Pentax K5 with a Pentax 17-70 f/4.

The only criterion this combo doesn't fill is the 24mm. It's more like 25.5mm.

However, the DA 17-70 is sharper at the wide end than the long end and it's very descent optically overall.

The K5 is one of the best performing camera, at any price, in terms of DR.

At ISO 80, it beats pretty much *everything* out there in DR, all APS-C based cameras, plus all full frames.

Check DX0mark for the graphs.

I just acquired a K5 myself a month ago and I'm very impressed by its IQ.



Here are some samples from a safari in Tanzania during Christmas.

Keep in mind most landscapes here were taken at ISO 80 (all single shots - no HDR):

The DR of the K5 is just amazing.



Hope this helps.
