I really appreciate all the feedback I have received over the past week or so since I first started thinking out loud on this subject. After digging a bit, I’ve narrowed my specifications. I could not find anything that covered all of my wants, and that forced me to concentrate on what I need. The first thing to go was AA batteries – it seems that virtually no DSLR works from AA’s. The next thing to go was video. Very few SLRs do video, and it appears none of them do it well.
I came back to the features that I need, which are small size and light weight. I took the suggestions of people I trust and fed them through that filter and came up with the cameras you see arrayed above. You can see the whole comparison table here. I think now, that unless something about the other two really strikes me, my final choice is between the two in the middle: The Olympus E-420 and the Panasonic Lumix DMC-G1. These two are the smallest, lightest DSLRs available, at 15.5 and 12.7 oz. respectively.
The more I look at the specs, the more I’m favoring the Panasonic, with it’s Leica lenses and apparently amazing tilt/swivel/swing viewfinder.
The Sony’s appeal is the price/performance, the viewfinder, and some impressive technical stats. It is HUGE compared to the Olympus & Panasonic. The Canon’s appeal to me lay primarily in its ability to be driven by a laptop for time-lapse. After thinking very hard about that I realized that the sort of time-lapse work I do, I’m better suited finding a compact consumer-grade digicam that is supported by my time-lapse software.
So my next step is to go and get my hands on these and see how they feel. Stay tuned!
