This year I attempted to thru-hike the Pacific Crest Trail. Unfortunately, 700 miles in I had to quit because of a stress fracture...
I took the DP2M for this trip, as the landscapes in the desert are foveonic, and overall I'm not disappointed. I have had a few problems in some shots though, I'm not sure if it's because of motion blur (even at 1/125 s, all my pics are handheld shots, and sometime it was very windy) or maybe I was too much in a hurry sometimes and pressed the button too soon before the focus was locked. Also, I may have been too stubborn with 100 ISO shooting - actually up to 800 ISO the DP2M performs well IMO, and it's better to have a little bit of noise instead of motion blur, at least it is manageable... Anyways, it is definitely a camera that has a certain learning curve and I'm still learning how to use it properly. The Merrills are actually a good school to learn proper photography: in a way they are unforgiving but that forces you to take better pictures at first place by being more methodological and patient. I have to be more patient.
Still, I have taken the DP2M on a 6-week backpacking trip in Southern California, I'm not an experienced photographer, so this camera might not be as silly as some would say. What I mean it that the DP2M is actually an easy camera to operate, because it is simple, and although it has some flaws (I think of battery life and speed), it is perfectly possible to use it in any conditions. It only requires some effort to get familiar with this "alien" camera. I'm not a "chain gun" shooter, I used to take only about 30 pictures per day. So it was possible for me to last a whole week with 3-4 batteries and recharge them in town stops. And for longer stretches, I used the battery pack/SAC-5 with and USB cable system - which worked great, although the cable was sometimes annoying.
Here are a few samples (any comments are welcome, help me improve!)
