Leica Q (Typ 116) compared to Sigma DP2 Quattro - Am I really bidding on a Leica M8?

Leica Q (Typ 116) compared to Sigma DP2 Quattro - Am I really bidding on a Leica M8?
'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.'

Super High Resolution Mirrorless - Olympus OM-D E-M5 II - Sigma DP2 Quattro

Super High Resolution Mirrorless - Olympus OM-D E-M5 II - Sigma DP2 Quattro
'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?'

Speeded up Sigma Photo Pro

Speeded up Sigma Photo Pro
'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.

Sigma DP2 Quattro in 21:9 mode

Sigma DP2 Quattro in 21:9 mode
'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. '

'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.'

Open letter to Sigma about the DP2 Quattro

Open letter to Sigma about the DP2 Quattro
'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.'

Sigma DP2 QUATTRO - Is this the best resolution I've ever achieved?

Sigma DP2 QUATTRO - Is this the best resolution I've ever achieved?
'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.'

Cameras that produce 100MB+ files - SONY A7R, SIGMA DP2 QUATTRO, NOKIA LUMIA 10120 COMPARED

Cameras that produce 100MB+ files - SONY A7R, SIGMA DP2 QUATTRO, NOKIA LUMIA 10120 COMPARED
'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. '

On location with the Sigma DP2 Quattro - shooting jpgs.

On location with the Sigma DP2 Quattro - shooting jpgs.
"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. "

Have Sigma finally got the Foveon Sensor right with the DP2 Quattro?

Have Sigma finally got the Foveon Sensor right with the DP2 Quattro?
"

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."

Sigma Quattro

http://www.mirrorlessrumors.com/updated-sigma-announced-the-new-sigma-dp-quattro

Ever the ones these days to spring surprises, this is the update to the DP Merrills. Extraordinary design with the huge lump on the right of the camera housing what Sigma say is a new more powerful battery.

So that addresses one of the major drawbacks of cameras using the Foveon sensor. Obviously no information yet as to how many shots you can get from the camera per battery, but with my DP Merrills I was carrying 5 spares for a days shooting so it won't be difficult to improve on that.

There is another huge difference as well. The three layer Foveon sensor has been altered in terms of the proportion of information from each layer. Instead of equal weight given to each Sigma have changed this to a 4:1:1 ratio, which they claim leads to faster processing and much better high ISO performance. The file size is also increased from 14MP to 19MP. 

Now Sigma claim that this will still give the same image quality, sharpness and colour depth of the previous Sigma sensor while addressing the issues that made the DP Merrills both wonderful cameras and incredibly frustrating ones at the same time. It's still the same line-up as with the previous models. There are three with 19mm, 30mm and 50mm lenses. This is from the Sigma press release:-
'The dp series comprises three fixed focal length cameras, each of which features a different basic focal length for a different fundamental photographic approach: the wide-angle dp1 Quattro at 19mm, the standard dp2 Quattro at 30mm, and the medium telephoto dp3 Quattro at 50mm (respectively equivalent to 28mm, 45mm, and 75mm on a 35mm lens). Moreover, the three models share an exciting new camera body that brings out the best performance from the lens and image sensor.

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?
