Product Description

The Sigma DP3 Merrill, the latest iteration of the company's enthusiast large sensor compact camera. Nearly identical to the earlier DP Merrill models, this camera features the familiar 15x3MP APS-C Foveon X3 sensor, but it is now mated with a 50mm (75mm equiv.) F2.8 lens. The lens lends itself to portraiture and, with a minimum focus distance of 22.6cm, offers respectable 1:3 magnification. Video recording is still limited to VGA resolution but the DP3M can shoot at up to 4 frames per second for 7 frames in Raw.

    Very good for a certain purpose, not as an everyday camera

    I got the Sigma "dp3m" after reading about its extremely good image quality. From the reviews I gathered that the camera was not very good otherwise, and this is in a sense true, but my experience has been all-round positive. Using the camera is oddly a little bit like shooting on film, you don't really know what you got until you develop the images in Sigma's own software (Lightroom and ACR do not support the Sigma file format). The controls of the camera are intuitive and quick to access. ...

    About the Sigma DP3

    It's a slow beast, but if you have the patience to use it right, the IQ is astonishing.  Not higher than 400 ISO, however.  I use it in the studio (because it SYNCs) and it because practically replaces a Hasselblad w/80mm.

Sigma DPn Merrill battery life with screen off

I used to have the first Sigma DP1. I loved looking at the images on the screen coming from that camera. It was so sharp, every pixel adding details to the scene. When the Merrills were released, the price was quite prohibitive, and so I didn't even consider any of them, and kept on using my MFT gear quite happily. Recently, I discovered that the prices of the Sigma DP Merrills have become not only cheap, but dirt cheap, when you consider the fact that just buying an equivalent lens would set you back the same as buying the whole camera, and I got more interested again. A lot of my photos are textures and patters from nature and urban settings: rocks, wood, weathered paint, frost, etc. - often scenes with hardly any dynamic range but a lot of detail - things that a Foveon sensor excels at. But I do hear a lot of mention of battery life - or lack thereof - and I was trying to Google to see if anyone had actually tried using any of the DP Merrills with the screen entirely off, using ...

Yes. There was a fashion photographer around here within the last month and he shot with the screen turned off. Manual focus. Bash bash bash. I think he was doing well over 100 fashion shots a day. Some shots failed but gosh he clocked up the miles. Do some searching on this forum. I could do it for you and will if you fail. But the answers are there. EDIT. Here it is. Aren't I kind.

It's a non-issue. As written, the batteries are inexpensive and small; I received two with my DP2M and purchased two more for about $30 each. I certainly wouldn't change my shooting style, or try to avoid chimping, just to avoid having to take a couple of seconds to switch out a battery. Actually, I'm not sure I've even had to change batteries in one shoot, although I haven't done any serious winter shooting which will severely limit any battery's life. I usually have two cameras with me and the nature of the DPx cameras is that you have to spend some time composing and planning each photo (like in the old film days) so you take fewer photos but have more keepers. They're not like dSLRs where you find yourself shooting 10 RAW shots per second hoping to get one decent shot...and you're not going to be using a Merrill for sports, BIF, etc. Continue Reading

Is the DP3 Merrill supported by DCRaw?

Sorry to have wasted everyone's time on the wrong thread. It is the DP3 Merrill that I want to convert using Qimage. According to this list the DP1 and DP2 will work with DCRaw that is used within Qimage. If there was a DP3 Merrill raw file that I could download from the Sigma site I could test it myself. Tony

Is the new RayFlash universal Ringflash adapter Sigma-compatible?

I'm wondering, whether I could use this newly introduced RayFlash universal Ringflash adapter on the Sigma DP3M (possibly also DP1/2M, and also an old DP-series-cam), when supposedly using it in combination with the Sigma EF 610 DG Super flash. Would it also likely work on the SD1(M) when the new 18-35mm 1.8-lens is attached, in combination with that same EF 610 DG Super flash? I just haven't any clue whatsoever, which is why I'd happy, if someone here (or wherever really...) could tell me or at least attempt taking an educated guess on this matter. Thank you so much in advance for your truly valued and assumedly helpful replies ;-)

I don't think there's any way to tell without trying, but it looks very promising.   I may see if I can fine one at a local photography shop and see how it fits. Continue Reading

Why?  The other one has adjustments to fit multiple flashes and bodies, the one you listed is specific to a Canon flash and a set of Canon bodies... Just looking at it I am almost certain it would not work on an SD-1 with an EF flash. Continue Reading

Thanks for the link, but this Amazon-thing looks nowhere near as refined and, if you like: high-end, as the original RayFlash. But thanks. Continue Reading
