A Mini user review of Sigma Dp1 & DP2 Merril
I thought it would be interesting for everybody to have a look at some work done with the Sigma DP1 and DP2 Merrill cameras. I also shoot with a Leica M9 and various lenses but at 68 and wearing glasses I find it harder and harder to focus when necessary (i.e., when not using zone/hyper focal technique.) The Sigma DP1 (19 mm lens) and DP2 (30 mm lens) Merrill’s are simple, little black boxes that seem well constructed and sturdy. Autofocus is just about as fast and accurate as a NEX-7. All autofocus systems are problematic including, I’ve read, the Nikon D800E. I use my Sigma’s with optical viewfinders which gives a speed and fluidity similar to using the Leica with a wide-angle lens but a little more assurance in focus. When precise framing is necessary the back LCD serves well enough. The menu/control system of the camera is spare and Leica-like. There is PASM, EV adjustments, iso adjustment in 1/3 stops and not much else. There is a movie mode but I don’t use it so I can’t comment. Definitely more photographer than engineer-oriented. Definitely few features.
Sigma Photo Pro (SPP) is the RAW developer that has to be used as ACR/Lightroom does not (and maybe will not) support Sigma/Foveon. Iridient will be coming out with a raw developer that will develop dp1/2m files in a few weeks but generally I’ve found that using SPP with a few minor adjustments and then batch converting to TIFFs to be completely satisfactory. The TIFFs are then imported into Lightroom 4 which handles them as usual. I see no degradation of image between Lightroom manipulation of the TIFF and straight processing through SPP. Sigma has also been very quick in providing updates: 2 upgrades to SPP and 3 firmware updates between the two cameras since I’ve owned them.
As has been reported elsewhere (see Michael Reichman’s reviews at Luminous Landscape) the image quality produced by the tiny Merrill’s is extraordinary. I’ve never seen detail like this before from any camera and certainly not from the M9 or NEX-7. The color is true, saturated and satisfying. The lenses are good and do not limit the sensor.
As is also well-known, the camera really only functions well at very low iso– 100 or 200. I’ve done a modest amount of work at iso 800 which is passable but things go well at even higher iso if converted to B&W and then “de-noised” in Lightroom or even SPP.
