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.

Questions & Answers


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

Someone from GETDpi has found me a source. It does seem that Qimage will not convert the RAWs. Drat. Tony Continue Reading

DP3M and Panasonic DE-A40 Battery Charger

I left my charger for battery somewhere in Kyoto, Japan last month..since then three out of four batteries completely in desperate I seek out charger at handphone and camera mall in my city Bogor, Indonesia. They offered me Panasonic DE-A40 battery charger with electrode and chamber just fit to BP-41..but its output is 4.2V 0.8A while BP-41 is 3.6V 1.25A.. Pls somebody teach me whether the electronic equation is safe or not..? So far I’ve succeeded charging the three batteries once without overheat.. Bambang

I've got the Panasonic DE-A42 charger with my LX3 and this seems to be identical to the Sigma BC-41 at least from specs. Interestingly, the batteries for the LX3  are 3.7V, while the Sigma are 3.6V. Continue Reading

I've read somewhere in this forum that we can use Ricoh DB-65 for DPxM. When I googling DB-65 there came out Wasabi Power Battery and Charger Kit for Leica BP-DC4, C-Lux 1, D-Lux 2, D-Lux 3, D-Lux 4 which fit: PENTAX X90 RICOH Caplio GR Digital LEICA C-LUX1, D-LUX 4, D-LUX2, D-LUX3 FUJIFILM FinePix F40fd, FinePix F45fd, FinePix F47fd, Finepix F20 PANASONIC CGA-S005, CGA-S005A, DMW-BCC12, Lumix DMC-FS2, Lumix DMC-FX01, Lumix DMC-FX9, Lumix DMC-LX1, Lumix DMC-LX2, Lumix DMC-LX3 On the other hand, the Panasonic DE-A40 I'm now using for DP3M fit these cameras: Lumix DMC-FS3 Lumix DMC-FX30 Lumix DMC-FX55 Lumix DMC-FS5 Lumix DMC-FX35 Lumix DMC-FX37 Lumix DMC-FS20 Lumix DMC-FX500 Lumix DMC-FX33 Lumix DMC-FX60 I hope the above list can be of any helps for people looking for (emergency) replacement.. All best, Bambang Continue Reading

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

mike earussi wrote: Or you could use this one instead (it's a bit cheaper): and probably just as likely to work. 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
