We've
just received our review Sigma SD10 (after a little mix-up with the courier)
and I'm happy to report that resolution is identical to the SD9. I decided
to test this immediately after we read reports elsewhere that resolution
was significantly lower because of the use of microlenses. In our own
shots of a standard ISO resolution chart we can measure absolutely no
difference in resolution between the SD9 and SD10 using the same lens
at (almost) the same aperture.
As per our Sigma SD9 review we found the SD10's resolution to be identical, 1550 lines per picture height in the horizontal and vertical direction. Note that the difference in aperture (F9.0 vs. F9.5) is because of the change from 0.5 EV exposure steps on the SD9 to 0.3 EV exposure steps on the SD10.
