'So it's obvious that Sigma are going for a market that craves sharpness and detail resolution over all else and isn't that bothered about high(er) ISO performance. Aimed straight at me of course. And I have to say that since I can upsize my current camera files to 50MP with astonishing results, what can I get from the H?'Read More
'It doesn't happen too often, because I normally take a long while to get round to editing and uploading images, but occasionally I take a picture, caption, keyword and upload it to a stock library and achieve my first sale the same day. It was like this yesterday with the image above and the three below.'Read More
'.......this is -(Please note I chose my words VERY carefully here) The best image quality I have ever seen at low ISO's of any APS-C AND Full Frame camera as well as some Medium Format Sensor cameras.'Read More
'The Foveon sensor with it's high-resolution ultra-sharp images would seem to be a likely candidate for shooting low ISO stock landscape / location / nature / travel material. And while that is certainly true, there are a few issues that make it less than ideal to use.'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
'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.

"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."
