Sigma DP1 Merrill


The Sigma DP1 Merrill is capable of producing amazing images, but you'll have to put a lot of time and effort in to get the most out of this pricey point-and-shoot.

Very sharp lens. APS-C Foveon image sensor. 28mm field of view. Sharp rear LCD

Cumbersome Raw workflow. Poor JPG output. No HD video support. No EVF option

The Sigma DP1 Merrill ($999 direct) is the latest iteration of the company's ground-breaking DP1, which, back in 2009, was the first digital compact to squeeze a D-SLR sized APS-C image sensor into a pocketable body. The market is a bit more saturated...

Sigma DP1


SLR quality in a point-and-shoot form ; Excellent image quality ; Can easily isolate subjects with shallow depth of field ; Solid camera construction

Mediocre LCD ; Sigma's raw processing software is limited and clunky ; Sigma raw files not supported by Aperture or iPhoto ; Slow to focus and save images ; Images shot above ISO 800 are overly noisy

Sigma DP1 Compact Digital Camera with DSLR-Sized Sensor


Sigma's new DP1 compact digital camera has the same large Foveon sensor as in the SD14 DSLR, yet it can fit in your pocket. Read Secrets exclusive, detailed bench test report to see how it compares with its larger SLR cousins.

The Sigma DP1 is a major advance in compact digital cameras, but it does have its problems, including no zoom lens, slow in taking photos, not very good low light performance, and only focuses down to 12" However, the picture quality in good light is...

Sigma DP1


The Sigma DP1 is without doubt one of the most eagerly anticipated cameras of late, certainly in the compact camera sector. Sigma first presented a concept prototype of the DP1 at Photokina 2006 but the first production models only hit the shelves in...

Class leading detail in ISO 100 images, higher ISO performance better than most compact cameras ; Resolution is as good as it gets in compact cameras, very impressive for output size ; Good dynamic range (though limited usable headroom in raw files) ;...

Desaturated and 'flat' JPEG output ; Some chroma noise even at base ISO, lots of it at higher sensitivities ; Unreliable White Balance (and poor color in low light) ; Generally very slow, very long read/write and processing times ; Unimpressive shutter...

I'd like to start this conclusion by saying that Sigma deserves an incredible amount of credit for doing what none of the 'big' manufacturers so far have been bold enough to do. In an industry that focuses its marketing efforts almost exclusively on...

Highly Recommended!

Sigma DP1 Review


Who would have thought that Sigma, with its comparatively tiny budget and short history of producing cameras, would release one of the most important compact digital models of 2008, and perhaps of all time? The principal reason for this bold assertion...

The Sigma DP1 offers the best image quality, JPEG or RAW, of any compact camera currently available today and in many ways equals DSLR cameras with APS-C sized sensors. There is virtually no noise throughout the ISO range, only at the fastest setting...

Sigma DP1 Digital Camera - Review - The Imaging Resource!


The Sigma DP1 was designed for anyone wanting digital SLR quality in a small package. Starting with the Sigma DP1's sensor, Sigma chose Foveon's 14.1-megapixel sensor that outputs a 4.64-megapixel image. Each of those pixels is created by three...

Excellent optics, though maximum aperture is a bit slow at f/4 ; Very low barrel distortion ; Very little chromatic aberration ; Foveon sensor captures smooth, well-defined detail ; Small camera design is easy to bring along ; Good button placement ;...

JPEG images are of poor quality, with little consistency from shot to shot ; Sensitivity tops out at ISO 800 ; Lens cap is a pain to put on, doesn't work with lens hood ; Difficult to manual focus without close measurements ; Not good for Macro...

There's no optical viewfinder on the DP1, but Sigma offers an optional external viewfinder that mounts in the flash hot-shoe. Images can however be framed on the 2.5-inch LCD -- the same size as is used in the SD14. While there's no optical zoom, the...

Review: Sigma DP1 and DP2 digital cameras


The Sigma DP1 and DP2 feature image quality that's truly on the same scale as entry-level SLRs, but they have clunky controls.

Before continuing, it’s important to note that the lens is the primary difference between the two Sigma cameras. The DP1 has a 16.6mm (28mm film equivalent) f/4 lens and the DP2 has a 24.2mm (41mm film equivalent) f/2.8 lens. The wider, slower lens on...

The Sigma DP1 would have been ahead of the curve a few years back. Today it looks like a rusty Brett Favre.

Sigma DP1 Selective Focus


In our test report, we confirmed Sigma's claims that the larger "DSLR-sized" sensor on the DP1, along with the larger pixels it contains, helped this camera achieve the highest image quality rating we've given a compact digital camera all the way up to...

Sigma's DP1 Digital Camera; Foveon Sensor & 14 Million Photodetectors In A “Compact” Digicam


First announced as a "product under development" in September 2006, the DP1 finally became available 18 months later and it was worth the wait. Aside from solving some image quality issues, the engineers also modified the specifications, delivering a...

While I have no scientific method of measuring pure resolution, the DP1 produced superb JPEG quality at ISO 100, with the definition of intricate detail expected from an 8-megapixel D-SLR. In raw photos made at ISO 100 to 400-and converted with the...

Product Specifications

The Sigma DP1 compact digital camera uses three silicon embedded layers of photo sensors stacked to take advantage of silicon's ability to absorb red, green and blue light at different respective depths. The size of image sensor used in DP1 camera is approximately 10 times larger than those used in an ordinary point and shoot digital camera. The direct image sensor featured in the SIGMA DP1 ensures the capture of full and complete color. This camera incorporates both RAW and JPEG image recording formats enabling photographers to capture the highest possible picture definition and smaller file sizes. The Sigma DP1 camera features a large 2.5inch, 230,000-pixel resolution LCD monitor. The LCD monitor displays 100% of the image, allowing the photographer to easily and accurately confirm the image composition.
