'Add in the fact that the Leica is MUCH better at high(er) ISO's and a faster camera as well and it's clear to me which is the most useful camera. However, the fact that the Leica costs 4x as much hasn't escaped me.'Read More

'Both the Olympus OM-D E-M5 II and the Sigma DP2 Quattro have pretensions to offer super high resolution images. The Olympus, via it's High-Res mode offers a 40MP jpg. and a 64MP raw file. This however requires no subject movement, an exposure that requires sensor shift and therefore a tripod. The Sigma offers a S-HI jpg. option which is 39MP and an incredible 'Double Size' option from raw which is an unbelievable 78MP. So do these options produce what these numbers indicate, very high resolution images. And if so, are they actually any good?'Read More
'After getting my Sigma DP2 Quattro, I tried out the Sigma raw software - Sigma Photo Pro - and quickly came to two conclusions. Firstly it worked with almost mind numbing slowness, with adjustments and saving taking several minutes to complete and secondly I didn't see much benefit over the in-camera double size jpg. files I was creating. However, with the acquisition of my new PC tower with i7 turbo boosted quad cores and 16MB of Ram, I thought I'd try it again. And Sigma have seriously updated it.Read More
'In a previous article about the Sigma DP2 Quattro I wrote that it may well follow my usual Sigma Foveon sensor camera experience. Buy it, rave about the images quality, get frustrated by it, sell it. However, this time this camera is still around. And it's more likely (though not certain) to continue to do that since I've been exploring the various crop modes. You can shoot in 1:1, 3:2, 4:3, 16:9 and as above in 21:9. With the OOC double size jpgs. the camera produces, this crop still gives a large file of incredible quality and I have to say I really (really) like the compositions I can get with it. 'Read More
'A somewhat less glamorous view of the English canal system, but one that has proved successful for me in terms of stock photography sales. I used the Sigma DP2 Quattro and tried out the very odd combination below to give myself a decent viewfinder.'Read More
'I have used Sigma cameras with the Foveon sensor for sometime now. The results have always been very impressive. The DP2 Quattro has moved the concept on in terms of image size, better high ISO quality and camera processing speed, though Sigma Photo Pro still leaves a lot to be desired. However, I and I'm sure many other Sigma users are frustrated by certain things. Firstly the fact that there is only a fixed focal length lens. And secondly that there is no built-in EVF.'Read More
'Regular readers will be aware that I do like an 'odd' camera / lens combination. Realising that with the addition of a 58mm > 49mm reversing ring I could attach my Fuji wide and tele converters to my Sigma DP2 Quattro, I gave it a try.'Read More
'So all in all a success story. This camera is a step up from the Merrills for my uses and the files I can create with the DP2 Quattro are jaw dropping. It isn't the best for dynamic range certainly, but running the jpg. files through Adobe Camera raw helps with that. As I said, not a camera for all situations, but used for what it's designed to do well, slow detailed high resolution images in good light, it's really in a class of it's own. Literally.'Read More
'I have three cameras that will output huge 100MB+ jpg. files. The Sony A7r with it's 36MP from a 35mm / 'Full-Frame' sensor, My Nokia Lumia 1020 Smartphone with 38MP from a 1/1.5" Micro Sensor and My Sigma DP2 Quattro with a whopping interpolated 39MP from it's APS-C Foveon three layer sensor. Now it should be a forgone conclusion as to which produces the best image quality, but this post examines what each camera actually produces rather than just making the usual photographic internet assumptions. 'Read More
"This is the somewhat 'old school' option of getting everything right in camera and cutting down the editing workflow to a minimum. This process therefore turns the camera into a fast operator, somewhat surprisingly. This is achieved by the fact that firstly the metering is spot on and secondly by the fact that the internal jpg. processing turns out files that require very little levels adjustment in terms of contrast, that is much more akin to shooting transparency film than the 'elasticity' of digital. 'Buy a Sigma Foveon sensor camera and cut down on your editing time' is hardly something I expected, but I'm pleased to say for me that is indeed true. "Read More
Now I really wasn't planning to get one of these. After my experiences with The DP Merrills which despite their extraordinary image quality were 'difficult' cameras to use. (To say the least!) I had written Sigma / Foveon off as an interesting footnote in camera development, but one that wasn't going to be for me anymore.
I was persuaded otherwise by a friend who bought one and implored me to go and give it a try. I used it for a few hours and took some pictures with it. On returning I looked at the pictures on my screen and promptly ordered one there and then. Because in terms of both the image quality (expected) and the handling and redesign (unexpected) this is a very impressive camera."
It’s a simple but powerful lineup that delivers medium format-level image quality anywhere, anytime. Take all three with you and select as needed for the perfect shot. Only the dp series puts so much luxurious photographic potential in your hands.'
So they are very much pushing the line that suggests you use and think of them more or less as buying three separate lenses with image capture and a processor bolted on. Maybe this means they might be cheaper than the Merrills??
Obviously no-one has the faintest idea, apart from Sigma, as to whether this will all work as advertised. But Sigma have a good track record these days in terms of innovation that lives up to expectation and if that is continued we could end up with a pretty unique set of cameras and a different way of approaching picture-taking. I was a huge fan of the DP Merrills image quality at base ISO but found it difficult to deal with pretty much everything else, so this is something that looks very interesting indeed. The 14MP images that the previous cameras produced when upsized to D800E (and now of course Sony A7r) pixel counts looked virtually the same, so you can get an idea of just how good they were.
However the images from these new cameras will need show a significant improvement on that to make me jump in and buy them again. Medium-Format quality from something that looks that bizarre? Who knows. But you have to give Sigma a lot of credit for trying to make this work. Oh and by the way, can I PLEASE have one to test?
