Triple your resolution for outstanding color and detail

It takes a special sensor to elevate a compact camera to SLR-class photography. The Sigma DP1 Merrill has just such a sensor. This unique camera's namesake, Dick Merrill, co-developed the Foveon X3® Direct Image sensor used by the DP1 Merrill to capture superior amounts of color and detail. Typical sensors can only capture one primary color (red, green, or blue) at each pixel site. So Merrill developed the X3 with three stacked receptors to capture all three primary colors at each pixel. This effectively triples the camera's 15.4-megapixel resolution to what Sigma calls 46-megapixel resolution. The results are incredibly rich and vibrant colors, remarkable detail, and a sense of depth few cameras in any class can convey.

High-performance wide-angle lens

Sigma took care in pairing a well-designed lens with its outstanding sensor. The fixed 28mm-equivalent wide-angle lens is made of nine elements in eight groups and features a nine-blade diaphragm with an f/2.8 aperture value. Sigma used its high-quality "F" Low Dispersion (FLD) glass for excellent light transmission to take full advantage of the sensor's ability to resolve subtle color detail. And the Super Multi-Layer lens coating minimizes reflections and flare. The combination of lens and sensor makes the DP1 Merrill ideal for shooting outdoor scenes, whether you're taking wide-angle shots of gorgeous landscapes or close-range shots of a beautiful flower. 

Manual controls and video shooting

In addition to these unique features, the DP1 Merrill features a manual focus ring as well as contrast-detection auto focus. Its manual and priority exposure modes provide plenty of options to play with this camera's unique approach to light and color capture. You can also shoot video and record voice memos, for a little extra versatility from this impressive camera. And because of its compact design, you can easily bring the DP1 along with your DSLR gear, though it could very well become your go-to camera whenever you're trying to capture the beauty and color of the outdoors.

Foveon X3 Direct Image Sensor: The Sigma DP1 Merrill is a compact digital camera, equipped with the 46-megapixel, 23.5 x 15.7mm Foveon X3 Merrill Direct Image Sensor (CMOS). This technology was originally developed by Dick Merrill, a talented photographer and brilliant engineer.

Image Processor: The dual "TRUE (Three-layer Responsive Ultimate Engine) II" image processing engine, specifically made for the Foveon X3 direct image sensors, improves the processing speed and overall quality of the final image. By incorporating two True II processors, Sigma's unique image-processing algorithm provides high resolution power and reproduces high definition images with richly graduated tones as well as a three-dimensional field.

LCD Monitor: The DP1 Merrill has a 3" TFT color LCD monitor with 920,000 pixels. You can choose from 17 languages on the monitor, including English, Spanish, French, German, Italian, and Russian. The camera does not have a separate viewfinder.

Recording Media: You can record still images and movies on SD, SDHC, and SDXC cards. Multi Media Cards (MMC) can also be used, but not recommended for recording movies or continuous shooting.

File Formats: The DP1 Merrill records still images and movies in the following file formats:

  • JPEG: You can record JPEG images in High (4704 x 3136), Medium (3264 x 2176), and Low (2336 x 1568) sizes in 3:2 aspect ratio. JPEG images can be stored at three compression ratios: Fine, Normal, and Basic.
  • RAW: The RAW file format records the image data as captured by the camera image sensor without further processing. The images show almost no deterioration in image quality, and are a higher quality than JPEG images. To view RAW images on your computer, you must first process the images with Sigma Photo Pro downloadable software. RAW images can be recorded in the same three resolution sizes as JPEG images.
  • RAW + JPEG: At this setting, one RAW image and one JPEG (Fine) image are recorded simultaneously. You can choose from High, Medium, or Low resolution.
  • Movies: Movies can be recorded in Standard Definition with monaural sound in AVI format. Movies are recorded at VGA 640 x 480 at 30 fps. The maximum recording data size for one movie is 2 GB. The recording will be terminated automatically when the recording data size exceeds 2 GB.

Lens: The DP1 Merrill is equipped with a 19mm fixed focal length lens (35mm equivalent 28mm), which has been designed specifically for this camera to maximize the sensor performance. The F2.8 - F16 lens has a shooting range of 7-7/8" (20cm) to infinity in normal mode, and 39.4" (1m) in Limit mode.

Quick Set Menu: The DP1 Merrill has a Quick Set Menu to let you quickly access and change the camera settings. Initially the Quick Set Menu 1 has the ISO setting, Metering Mode, Drive Mode, and Flash Mode, while Quick Set Menu 2 has White Balance, Image Size, Color Mode, and Image Quality. You can also change the menus to include the following functions: Bracketing Amount, AE Metering Mode, Contrast, Sharpness, Saturation, and Exposure Mode.

Grid Segment Display: To assist you in composing the picture, you can display grid lines with solid or dotted lines. You can choose 4 segments (2x2), 9 segments (3x3), or 16 segments (4x4).

Drive Modes: The Sigma DP1 Merrill features the following Drive modes:

  • Single Capture: The camera captures a single image each time the shutter button is fully pressed and released.
  • Continuous Shooting Mode: You can use this mode to shoot successive frames while the shutter button is fully pressed. The maximum number of frames and speed depends upon the image size: High (7 frames @ 4 fps), Medium and Low (14 frames @ 5 fps).
  • 10 second Self-Timer: The 10 second self-timer can be used to shoot a group photo that includes the photographer. The camera will activate approximately 10 seconds after the shutter button is pressed to allow the photographer time to get into the shot.
  • 2 second Self Timer: The 2-second self timer can be used to avoid camera shake. The camera takes the shot 2 seconds after the shutter button is pressed.
  • Interval Timer: The camera can be set to take photos at a set interval. The interval can be set from 15 seconds to 60 minutes, and the number of exposures can be set from 2 to 99 times.
  • Unlimited Shooting: While holding down the shutter button, you can continue to shoot until the card is full. The image size is set to 1632 x 1088 and the image quality is JPEG Fine. The maximum shooting speed will be approximately 1.5 frames per second.

Exposure Modes: Using the Mode Button on the top of the camera, and the mode selection indicator on the bottom of the LCD monitor, you can select from numerous Exposure Modes:

  • Movies: Movies are recorded in AVI format with an image size of 640 x 480 (VGA) with monaural audio and a frame rate of 30 fps. You can record approximately 10 minutes of video for each 1 GB of available memory. Maximum file size is 2 GB per movie.
  • Manual (M): The aperture and the shutter speed are manually set. The aperture value (F-number) and shutter speed are displayed at the bottom of the LCD screen, along with the exposure meter. You can adjust the aperture and shutter speed until the exposure meter indicates +/-0.0 for the correct exposure. The exposure meter can display an exposure error of up to +/-3 stops from the correct exposure in 1/3 steps.
  • Shutter Speed Priority (S): When you set the shutter speed, the camera sets the aperture value according to shooting conditions. The shutter speed can be set between 1/2000 and 30 seconds.
  • Aperture Priority AE (A): After you set the aperture, the camera will determine the appropriate shutter speed according to shooting conditions. The aperture can be set between F2.8 and F16.
  • Program AE (P): The camera automatically sets an appropriate combination of shutter speed and aperture values. You can change the combination (Program Shift) by turning the top-mounted command dial. In one direction, the shutter speed increases as the aperture value (F-number) gets lower. In the other direction, the shutter speed decreases as the aperture value gets higher.
  • Custom Modes (C1/C2/C3): You can register commonly used shooting modes and settings to your preference. You can store the settings for Exposure Mode (M, S, A, P), the focus frame, exposure compensation, and all items in the Capture Settings menu. Up to three patterns can be stored (C1, C2, and C3).

Exposure Compensation: When shooting against a bright or dark background, you may need to correct the exposure so that the subject is correctly lit. You can adjust the exposure from -3 to +3 in 1/3-stop increments.

Auto Bracketing: The Auto Bracketing function lets you take a sequence of three photos at different exposure levels: Appropriate Exposure, Over Exposure, and Under Exposure. You can set the bracketing amount in 1/3-stop increments up to +/-3. Auto Bracketing can be used in the P, A, S, and M modes, and in Single, Continuous, 2 second and 10 second self-timer, and Infinite Shooting Drive Modes. The bracketing order can also be changed.

Focus Modes: You can toggle between Auto Focus and Manual Focus modes. In Auto Focus mode, the AF point is illuminated in green when focus is obtained and red when focus cannot be obtained. In Manual Focus mode, you can focus by turning the focus ring on the lens. There are two focus frames to choose from: 9 points select mode and Free Move mode. With Free Move mode, the size of the focus frame can be set to Spot, Regular, or Large.

Metering Modes: You can select from the following metering modes:

  • Evaluative: The screen is divided into 256 areas and the brightness of the scene is determined by independently measuring each area and analyzing the correct exposure for the main subject under any lighting situation.
  • Center-Weighted Averaging: The camera will measure the average brightness of the entire scene with additional emphasis on the center area.
  • Spot: The camera meters the area within the center focusing point on the LCD monitor.

ISO Settings: The Sigma DP1 Merrill features Auto and Manual ISO sensitivity. The higher the ISO, the greater it reduces the effects of camera shake and sharpens subjects in low-light situations. ISO speed settings can be adjusted in 1/3 EV or 1 EV increments. The 1/3 EV and 1 EV (underlined) settings include: 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000, 1250, 1600, 2000, 2500, 3200, 4000, 5000, 6400, or Auto.

External Flash: The camera does not have a built-in flash. The top-mounted hot shoe will accommodate an external flash. With an external flash attached, you can set the flash mode to: Normal, Redeye, Slow Sync, and Redeye + Slow. You can also set Flash Exposure Compensation from +3.0 to -3.0 stops in 1/3-stop increments.

White Balance: You can choose from the following white balance settings: Auto, Daylight, Shade, Overcast, Incandescent, Fluorescent, Flash, and Custom.

Color Mode: You can select the desired Color Mode, depending on shooting conditions: Standard, Vivid, FOV Classic Blue, Neutral, Portrait, Landscape, B/W, and Sepia.

Product reviews from the Crutchfield Labs

Unlike any other camera available today

Written by Zak Billmeier, Staff Writer - Creative, on 7/9/2013 2:10:00 PM

The only difference between the DP1, DP2, and DP3 Merrills is the focal length of each one; they're the same camera otherwise.

I've been curious about the Foveon sensors in Sigma cameras for years, having seen some astounding results coming from them. The idea behind Foveon is great: capture actual pixels for each color instead of interpolating them. Such an idea is truly radical and different than every other camera maker at the moment.

So what can you expect from the Merrill cameras and the Foveon sensor? First and foremost, beautiful, vibrant colors. Also a richness and uniqueness to your images that is hard to define, just a certain something that can make your photo look like art rather than a simple image. Another thing is mind-blowing detail. When you nail focus with this camera, you'll see every hair, fiber,'s unlike any other camera I've ever used.

But you can't think of the Merrill cameras the same way as you do those with traditional sensors. First of all, since light has to pass through three layers rather than one, it's strictly a "good light" camera. In practice this means you should limit your ISO to 800 or so on the upper end, at which point noise and color blotchiness begin to creep in. You can push it a little farther if you convert to black & white.

So it's not a "do it all" camera, but what it does well it does very, very well. Better, in my opinion, than any DSLR or large-sensor compact available.

I'd recommend this camera to serious landscape shooters who like to make prints. If you sell landscape prints, your work will stand out using this camera. Perhaps studio shooters could find a use for it as well. I wouldn't recommend getting it if you like to shoot at ISOs over 800 much of the time — this is not the camera to step up to if you just want to photograph your kids.

Think of the Sigma Merrill cameras the way you'd think of any specialized tool. It's not meant to be the one camera to replace all other cameras. But if you like capturing the beauty of the world around you, it's perhaps the best tool you can have.
