The Sigma SD15 has been announced.  Actually it was first announced at Photokina 2008, but has just been “re-announced” with some additional detail.

SIGMA SD15 PHOTO above taken from DPreview.com news release which has camera specs and Sigma’s official press release linked HERE.

Of particular noteworthiness to me in Sigma’s Press Release is:

“”"… a 21 shot raw buffer at 3fps and 5 frame auto bracketing for HDR-enthusiasts.“”"

The SD14 [which I shoot with weekly] maxes out at a buffer of only 6 shots and for bracketing it can do 3 AEB +/-3.0EV (which Sigma has been able to do since 2002 with the SD9).  The Sigma SD15 now sports an auto-bracketing mode of 5 shots but rather than up to 3.0EV jumps between shots, TURNS OUT THE MAX JUMP FOR 5  AEB IS 1.7EV JUMPS BETWEEN. Still quite impressive and wider than you can get with 3 AEB with the SD14.

In fact, that makes the SD15 the leading entry level DSLR in terms of capturing a huge dynamic range.  The Sigma SD15′s 5AEB is going to be amazing for auto-bracketing for HDR.

I had uploaded a very, very quick and sloppy imprompu video to YouTube last year that shows how I conceptually use the dials on the SD14 to get a 6 frame capture for HDR use. The dials are the same on the SD15 so this video is helpful if you wanted to see how quickly you can make adjustments without digging into an LCD menu system like some DSLRs on the market.  The YouTube links is HERE and I’ll embed a smaller version below.
