Wait. . . or . . . Buy?

WAIT!

I have DP2, SD15, and SD1. Sensor on SD1 is very difficult to clean. Sensor resolution is so high that focus becomes absolutely critical, and the existing autofocus system is in my opinion simply not up to the job. Too bad, because I have a small fortune invested in SA-mount lenses. They work great on my SD15 though.

I suggest you wait until Sigma adds live-view sensor-based autofocus to the SD1, or until Sigma brings out an interchangeable-lens version of the DPxM. If you like your SD15 I say keep it and enjoy it, because the hi-res Merrill sensor is a whole different animal.

I still don't have a solution for the sensor cleaning problem I've been having so my goal at this point is to get a DP3M if I buy any Sigma at all. You can't remove the lens so you can't clean the sensor, and it always focuses using the sensor.

At this point I'm making much more use of my Fuji X-E1. It has sensor-shake cleaning, and it uses the sensor to autofocus, AND I can swap lenses. It might be too much to hope for but I hope that Sigma does the sensor-shake sensor cleaning in its next camera too.
