Here I am again with yet another Sigma DP body. For my hands, it feels superb when out shooting and when held correctly it really is easy to shoot with, and a joy. I loved the Merrill for its amazing image quality, which was the best I have seen in any small camera. Very much like Medium Format and in some ways even better. Now the Quattro has taken that image quality, improved the AF speed and other aspects and then jammed it into an all new body that is worthy of a whole conversation in itself.
This is complete OOC. Just resized to pixels wide and no sharpening. You can see the larger size if you click the image. For me, this is gorgeous out of camera color and IQ.
From detail to color to bokeh. It looks fabulous. So what is the Quattro? The Sigma DP2 Quattro is a super funky designed camera that houses a new Foveon sensor and it will give you some of the best image quality you have ever seen, period.
Why you ask? Well, shooting RAW means you have to process those files in the Sigma Slow Photo Pro software as the files from the Foveon chip are not compatible with any other software.
This means, no using lightroom for your Sigma DP2 files. The color and detail in these files is absolutely beautiful. Some of the best I have ever seen. The Quattro has a unique design as well and does not look like any other camera I have seen or used. It is long, oddball and with a strange reverse grip.It used medium-format film orand none of that paltry 6cm x 4. All hail the Mamiya 7, one of the true greats of the camera world. The Mamiya 7 was introduced in the mids as a successor to the Mamiya 6 which produced 6cm x 6cm rather than 6 x 7.
It was certainly the best quality you could get with a camera that could be handheld easily. It was a simple camera, manual focus lenses only, a small battery to power the metering system, and a very quiet leaf-shutter lens system.
The battery, by the way, lasted for years, no recharging needed after every shoot. There was a range of only six lenses, four really, as you can discount the over-ambitious mm lens, and I also shunned the mm.
There was also a 50mm lens but I never used one of those. I can gaze at those transparencies and immerse myself in the wonder of Half Dome and Bodie, etc. However, digital came along and broke up Mamiya and me. It simply outsharps both those cameras and pretty much everything else besides. This picture of a church and street lamp was shot at f5. Copyright rogerpacker. This is a portion of the picture above showing the incredibly sharp reproduction of the lamp, with the street buildings reflected in the glass.
Closing in even more on the lamp, you should be able to see and read the writing on the lamp on the left-hand side above the glass, which gives the installer the instructions, ROAD SIDE.
These sections are not enlarged, they are simply the pixels from the main picture. I never got round to using any of the Sigma Merrill cameras, mainly because I was put off by substantiated reports that the camera batteries lasted for only around 40 shots. The company seemed to acknowledge this by including two batteries in the box.
However, the cameras nonetheless built up a devoted following due mainly to the sharpness and pictorial quality. The first one launched was the DP2 Quattro, with a 30mm f2.
Sigma have also now released the DP1 Quattro, which has an f2. I am eagerly awaiting the introduction of the DP3 Quattro, which will have a 50mm f2. The Sigma DP2 Quattro has an elongated shape that reminds me of panoramic film cameras. At the risk of being boring, I feel I should point out a few technical details. Sigma introduced the Foveon sensor some time ago and it is a different sensor entirely from the usual Bayer CMOS sensors used by most other manufacturers.
The Foveon sensor does not use a low-pass filter, which is used in most other sensors to remove moire, and this is one of the factors which brings a 3D feel to the Sigma output.Note: Most of our test results on this page are derived from Sigma Photo Pro 6.
We normally base much our test results from camera JPEGs so that we're testing the camera and not third-party software, however the Sigma dp2 Quattro's image quality can be significantly different from SPP conversions.
Also, Sigma released firmware updates to the camera which affected JPEG image quality after we shot the bulk of our lab shots, and we didn't have the opportunity to reshoot them all with the latest firmware before we had to return the camera.
About average hue accuracy that also falls with ISO. The Sigma dp2 Quattro produces images with colors that are a little more saturated than most cameras at ISO and Default saturation is Dark red is pumped quite a bit, while purples and dark blues are boosted moderately.
Most other colors are close to idea or just pushed a bit, though cyan is undersaturated. Mean saturation falls rapidly above ISOthough, reaching as low as Most consumer digital cameras produce color that's more highly saturated more intense than found in the original subjects.
This is simply because most people like their color a bit brighter than life. Skin tones. The Sigma dp2 Quattro generally does a good job with Caucasian skin tones, but sometimes it renders them too yellow or with reddish or orange casts in shadow areas.
The very high resolution and unique processing also tend to exaggerate fine features such as wrinkles and freckles which can lead to somewhat unflattering portraits at default settings. Where oversaturation is most problematic is on Caucasian skin tones, as it's very easy for these "memory colors" to be seen as too bright, too pink, too yellow, etc. The Sigma dp2 Quattro shifts green and orange toward yellow, red toward orange and cyan toward blue, but most shifts in color are very minor; even the cyan to blue shift we normally see is quite small.
Mean "delta-C" color error at base ISO is 5. Hue is "what color" the color is. Indoors, incandescent lighting The Sigma dp2 Quattro's Manual white balance setting worked well indoors, but other settings produced moderate to strong color casts. Slightly higher than average exposure compensation required. Indoors, under normal incandescent lighting, color balance is reddish with the Auto setting, and the Incandescent setting resulted in a strong orange cast.
Manual white balance produced very good results, though. Our test lighting for this shot is a mixture of 60 and watt household incandescent bulbs, a pretty yellow light source, but a very common one in typical home settings here in the U.
Outdoors, daylight Very good performance outdoors in bright daylight, with about average exposure accuracy. The Sigma dp2 Quattro produced overly warm and yellow skintones with the Manual white balance in our "Sunlit" Portrait, so we preferred Auto white balance shot above left. Skin tones are pretty good if a little flat, though darker areas take on an orange or reddish tint. And despite the bright appearance, relatively few highlights were clipped.
Shadow detail is very good but noise in dark shadows is on the high side and grainy. The Sigma dp2 Quattro preserved all but the brightest specular highlights here, though it did generate some very dark shadows.
Shadow detail is again actually very good, though a little noisy and grainy-looking. See full set of test images with explanations See thumbnails of all test and gallery images. Resolution Extremely high resolution, about 3, to 3, lines of strong detail in "High" size files, about 3, to 3, lines of strong detail in "Super High" size files. A "High" size SPP conversion of our laboratory resolution chart reveals sharp, distinct line patterns to about 3, lines per picture height in the horizontal direction, and to about 3, lines in the vertical direction.
Some may argue for higher numbers, but individual lines begin to fade and merge with others at those resolutions. Complete extinction of the pattern doesn't occur before the limit of our chart 4, lines in both directions. Use these numbers to compare with other cameras of similar resolution, or use them to see just what higher resolution can mean in terms of potential detail.
Mouse over the links to compare how the Foveon Quattro sensor compares to a Bayer sensor of similar size and resolution. Low levels of noise suppression generally leaves excellent detail at base ISO.The Sigma dp2 Quattro replaces the previous-generation DP2 Merrill, with a radically reworked sensor and strikingly unconventional body.
In our Sigma dp2 Quattro review Andy Westlake takes it for a test drive. In the early days of digital photography, camera manufacturers experimented with all sorts of different body designs. But over time, designs have generally become more and more conservative, and now almost all digital cameras look very much like film cameras did. Which brings us to the dp2 Quattro. The concept has been through several generations, and expanded to three lenses offering 28mm, 45mm and 75mm equivalent angles of view.
But until now, the actual camera designs have been decidedly conservative square boxes with lenses on the front. The Quattro, in contrast, is very different indeed. It has a wide, low, slim body, with the lens offset towards the right. But the real talking point is its grip, which is an odd-looking affair that sticks out at an angle from the back of the camera.
How the Sigma DP2 Quattro became the new King of the Compact Cameras
It features an APS-C-sized In short this design uses three stacked layers with different colour sensitivities, in contrast to conventional sensors that measure either red, green or blue light at any given pixel location.
This gives Foveon images a unique look, traditionally showing impressive detail resolution and unusually fine pixel-to-pixel colour gradation. However, the design has also had its problems, most notably with image noise at only moderately high sensitivities of ISO or more. The lens has a 58mm filter thread, and a bayonet mount for the matched hood.

Sigma dp2 Quattro — Pros Exceptional low-ISO image quality Extraordinarily sharp lens Good control layout Sigma dp2 Quattro — Cons Poor quality at ISO and above Uncomfortable hand grip Bulky, awkward body shape Sigma dp2 Quattro review — Introduction In the early days of digital photography, camera manufacturers experimented with all sorts of different body designs.The DP2 Quattro's unique sensor outputs xpixel raw images at the highest resolution setting, and is comprised of four seperate layers, with three dedicated layers for capturing Red, Green and Blue.
The exact size of the image sensor used in the DP2 Quattro camera is Sigma are still the only manufacturer to use the Foveon X3 sensor, quoting the resolution of the DP Quattro as 39 megapixels. The Foveon solution uses 3 layers of stacked on top of each other, with each photodiode capturing all of the RGB data.
The Quattro sensor differs from the prvious generation by allocating 20 megapixels to the top layer which records both blue colour and luminance information, and only 4. Sigma say that this important change offers an an increase in resolution compared to the previous Foveon sensor, along with faster processing times and less noise, at least in the red and green channels.
Whilst this may be true, from the user's point of view the final image is x pixels in size, which limits how big you can print or crop the native image without interpolating it in Adobe Photoshop or another application.
The Sigma DP2 Quattro has a very unusual design that's quite unlike any camera that we've seen before.Camera Review - Sigma dp3 Quattro - For the color connoisseur
Measuring It's much too wide and bulky for that, primarily because of the lens housing which protrudes about 4cms out from the front of the camera body, not to mention the angular hand-grip. Utilising an aluminium alloy body, the Sigma DP2 Quattro is an exceedingly well built camera, certainly up there with the best that the other manufacturers have to offer. The DP2 Quattro has an under-stated, all-black appearance with a subtly textured surface, and together with the heavier weight this lends the camera a professional look and feel.
The all-metal tripod mount directly inline with the centre of the lens is a giveaway sign that this is intended to be a serious camera most compacts have a plastic mount squeezed into one of the corners.
Offering a fixed-focal length of 45mm in 35mm camera terms, the lens doesn't extend when the camera is turned on.
The construction of the lens feels rock-solid with no play at all in the metal lens barrel. The DP2 Quattro has a tactile manual focus ring, which makes it much easier to operate the camera if you prefer that way of focusing. Sadly it doesn't over-ride the auto-focus mode though, which would have been a nice feature, although the manual focus assist complete with on-screen magnification is a nice touch.
Obviously the fixed-focal 30mm lens, equivalent to 45mm on a 35mm camera, will immediately put a lot of people off the DP2 Quattro. If you want a different focal length, then the wider-angle DP1 Quattro has an equivalent 28mm lens, or the DP3 Quattro has a 75mm lens. The DP2 Quattro has a subtly sloped handgrip with a small leatherette area which helps you to keep a firmer hold, although we'd have liked to see a much bigger area covered by this material. Unusually the DP2 Quattro grip is bigger at the rear of the camera than the front, an arrangement that we could never, ahem, quite get to grips with properly, especially as the Focus button and Control Pad are located where your right thumb naturally wants to sit, while the metal lug for the shoulder strap digs into your fingers.
The DP2 Quattro's handgrip is definitely distinctive, but it has a rather detrimental effect on the camera's handling. Rather strangely the DP2 Quattro's looks bigger than it really is at first glance, until you realise that the 3-inch LCD is positioned within a much bigger glass panel, with a tiny activity LED on one side and Play button on the other.
If you'd prefer using an optical viewfinder to frame your images, Sigma offers the optional VF viewfinder, which fits into the flash hotshoe on top of the camera you can also use other third-party viewfinders with the DP2 Quattro. Sigma Photo Pro is a simple, straight-forward but rather slow application that doesn't compare that well with Lightroom or Photoshop in terms of features, but gets the job done and is free of charge.
We really wish that Sigma would support the Adobe DNG format so that we could use our favourite processing software from day one. It takes around 10 seconds to store RAW files, although thankfully you can take another shot almost straight-away, which addresses one of our main criticisms of the previous Merrill generation.
The DP2 Quattro even has a respectable burst mode of 3. Still, it's a big improvement on the DP2 Quattro's predecessors. The Sigma DP2 Quattro offers a full range of advanced exposure controls via the Mode button on top of the camera, including aperture-priority, shutter-priority, manual and manual focusing, with Auto and Program AE modes catering for the less experienced and three Custom modes so that you can save and recall your preferred settings.
There are no auto-everything or scene modes on this camera, which is a veritable breath of fresh air at a time when most manufacturers are stuffing their cameras full of clever technologies that take control away from the user. The aperture or shutter speed are set by using the forefinger-operated control dial on top of the camera which encircles the shutter button, with a new smaller control dial just behind the first one setting the aperture in the Manual shooting mode and exposure compensation in the other modes.
Auto-focusing remains one of the weaker points of the DP2 Quattro. There are 9 focusing points to choose from and three point sizes, but you can only select one at a time, with no multi-AF point system that virtually all other cameras have. There's a dedicated button down on the navigation pad for choosing the focus point, but it's still easier and quicker to set the focus to the middle point, then focus by half-pressing the shutter button and recompose the frame for off-centre subjects.
The DP2 Quattro's autofocus system still isn't exactly what you'd call snappy, especially in low-light.The latest, 45mm-equivalent, model features dramatic styling and a fundamental re-think of the company's Foveon multi-layer sensor design. The Quattro sensor still uses three layers to detect color information but now only captures its full, The sensor will also appear in 28mm and 75mm equivalent dp1 Quattro and dp3 Quattro models.

Sigma dp2 Quattro review
Fujifilm X-T 5. Shedding some light on the sources of noise. Mobile site. Reproduction in whole or part in any form or medium without specific written permission is prohibited.In a radical departure compared to the boxy shape of its Merrill predecessor, the Sigma dp2 Quattro's strange, elongated design might scare away some at first, but it's quite comfortable after you try it for a while. Similar to the earlier model, the new Foveon X3 Quattro sensor produces some truly stunning, high-resolution files -- as long as you limit yourself to ISO Performance-wise, the dp2 Quattro is still a bit clunky and sluggish regarding focusing speed, buffer clearing and battery life.
Overall, if you're looking for a much more portable, high-res landscape or portrait camera, the Sigma dp2 Quattro merits consideration. Phenomenal detail and "depth" at low ISOs; Extremely high resolution; Incredible image quality for the price and size at low ISOs ; Fast x-sync speeds; Unique design is unconventional but comfortable and balanced. At the Photokina tradeshow, Japanese third-party lens manufacturer Sigma announced development of its first compact digital camera.
A year and a half later, the Sigma DP1 -- the camera that started the trend for large-sensor, fixed-lens compacts -- hit the market. Although there have been many followups in the six years since, they've all shared that one most important hallmark of Sigma's camera line: the Foveon X3 image sensor. Sigma went on to acquire Foveon in November A radical change. But now, the status quo has gone out the window. With the Sigma dp2 Quattro and its simultaneously-launched siblings, the dp1 Quattro and dp3 Quattro -- the company uses a brand-new image sensor that's fundamentally different to those of its forebears.
It's still a Foveon chip, and in fact still carries X3 branding, but the Foveon X3 Quattro image sensor is a huge departure from the sensors which have preceded it.
Before we go any further, a recap of the Foveon X3 sensor would probably be appropriate. It has a pretty devoted following from a small subset of the photographic community, however, who've shunned more established name-brands in favor of Sigma's cameras.
How the others do it. Instead, they use a color filter over the surface of the sensor to reject most of the light before it reaches the photodiode, permitting only a limited range of frequencies to be gathered. That color filter array -- most typically a 2x2 pixel Bayer array with two green, one red, and one blue pixel that's repeated across the sensor surface -- allows color data to be recreated for the image.
Unfortunately, it also greatly reduces light-gathering efficiency, and reduces resolution -- especially color resolution.
For any given pixel location, two thirds of the color information must be interpolated read: guessed by looking at the values of surrounding pixel locations. The process of demosaicing to recreate the final image requires battery-sucking processor power.
