    I agree that the test is strongly influence by the lenses used. The G10 would not be in the running without the auxiliary tele. The D3 would pull ahead if I'd used a longer tele. But the panos illustrate some of the problems of the DSLR route. The sharpest aperture on the G10 is f/5.6; the 80-210 on my D3 requires f/11. This required me to shoot the D3 at 1/125 second, which might have been a little slow for the mount I had it on. Depth of field, even at f/11, is not as good as the G10 at f/5.6.

    Tom, This D3 vs. G10 test is well executed and produced important results. Some snapshots reveal better resolution for the G10, but others (Aster café) suggest better clarity with the D3. Although the D3’s sensor is capable of greater resolution than the G10, the maximum resolution of either camera cannot be exploited when using the long focal lengths typical of gigapans. So the lens was the great equalizer in your test. Had you used a $3000 lens on the D3, I think it would have won the contest. But such a heavy lens would require an Epic Pro. I think the primary way in which the Epic Pro will produce better results than lesser Epics is when used with superb lenses (e.g., Canon L series) which are generally too heavy for lesser Epics. My working hypothesis is that if you pay less than $1000 for a 300 to 400mm lens, it will be the limiting factor for resolution, and there will be no advantage to using a 10 to 24 MP sensor over using a 6 MP (full frame) sensor. So I agree that the Epic Pro does not serve the original Gigapan mission of richly explorable images with inexpensive equipment. There is a place for the Epic Pro, and I hope that those who are buying them understand where that is (a place where $900 for the Pro is 20% of the cost of your kit). There is also good reason to continue to pursue the original mission, and there is probably a market for an even smaller, lighter, cheaper, ready-to-use gadget that does what we already do with our current kludges.

    To my eye, the G10 version is sharper. Compare to www.gigapan.org/gigapans/46767/
