SGIMA DP1 Merrill

This is review of using SIGMA DP1 Merrill digital cameras.


The 19mm lens, the wide-angle charge of the DP Merrill series, produces a clean image with little distortion.
The camera body has a square shape with few irregularities, making it difficult to grip, but this can be improved by attaching a third-party grip.
The DP1Merrill and DP2Merrill are not that different in lens size, so the only difference is the lens nameplate and model number.
The dimensions of the three cameras are the same except for the lens, so options such as grips can be used interchangeably.
APS-C sized digital camera with a high performance sensor and fixed lens is a good choice for snapshots, but the DP Merrill series continues the tradition of Sigma compact digital cameras, with the disadvantages of poor battery life due to a poor electrical system and poor response time due to poor hardware.
There was a time when I had three of these cameras on hand because the manufacturer offered cash back a short time after their release, but I sold them soon after because I did not use them very often.
However, considering the X3F’s poor handling, battery life, and the fact that it will no longer be repairable in 2023, I think the Quattro series is a better choice.
The Quattro series’ ton fur body also has an impact, but its portability is not good enough. It is a pity that a camera with the Quattro sensor was not released with the DPxMerrill’s body.


The DP1 Merrill is a compact digital camera released by Sigma in 2012. Three models were released with different focal lengths: the DP1 Merrill, which is equivalent to 28mm on a 35mm camera, the DP2 Merrill, which is equivalent to 45mm, and the DP3 Merrill, which is equivalent to 75mm.
This digital camera is equipped with a third-generation Foveon sensor.
The sensor was the same APS-C size as the SD1, 14.5 megapixels x 3 layers.
The BP-41 battery is compatible with the DB-65 used in Ricoh’s compact cameras.
The minimum focus distance is 20cm, which is the minimum focus distance for a 19mm focal length.
Since this sensor only supports X3F for image recording, the image processing is very difficult, using only SPP. The DNP conversion utility is a freeware that converts X3F to DNG, but it was difficult to achieve the same quality as SPP without considerable processing of the image after conversion to DNG in the version used at the time. If I could get an image, I would use other software to fine-tune it, but it was a pity that this was not the case. However, since it is freeware, I have no reason to complain.
I found that I could develop the images with Affinity Photo, an image processing software, so I tested it on this page.
