The New Sigma Quattro H Images Quality And Design Review

The Sigma Quattro H is a mirrorless interchangable lens digicam with an APS-H (1.3x crop) indicator. It has a spacial quality of 25.5MP but uses a indicator technological innovation very different from other cameras, catching around 38M components of data and able to produce details with far greater stages of details than you’d anticipate from a normal 25.5MP digicam.

Key Features

  • 25.5MP Foveon X3 Quattro APS-H sensor
  • Hybrid (combined stage + comparison detection) auto-focus system
  • JPEG, X3F Raw or DNG computer file output
  • 2.36m dot (1024 x 768 pixel) LCD viewfinder
  • 1.62m dot (900 x 600 pixel ) LCD back screen
  • Dust and splash-resistant mineral magnesium metal body
  • In-camera Raw transformation (X3F only)

In maintaining Sigma’s record of idiosyncratic advancement, there are two factors that set it apart from most of mirrorless cameras: the use of a full-depth DSLR install (the organization’s own SA mount) and the use of a Foveon X3 Quattro indicator, which catches mild and interprets shade very in a different way from other cameras.

Sigma Quattro H Body And Design

The SD Quattro is a fascinatingly non-traditional piece of design, strong and (presumably intentionally) un-camera-like, it seems to represent a effective commitment to function. However, it’s nothing like as auparavant garde as its DP Quattro relatives and is all the convenient to use for that.

The digicam has a significant hold to house the digital camera’s usefully huge 14Wh battery power and it provides a pretty relaxed way to hold you. Sigma doesn’t give an assortment figure for you but the big battery power means you don’t have to regularly worry about it going flat. The pipe that expands from the front of the body, to provide the detail for its SA install, gives an easy place to support you with your left-hand, giving a constant way to support it, two-handed.

On top of you are double control calls, which are well placed and readily available from the capturing place. Varied down the right-hand part of the back display is a sequence of control buttons that give you accessibility key capturing features, which are then set using the calls. Immediately behind the front change is the ‘QS’ key that accesses the digital camera’s quick configurations selection, which gives accessibility many of the key configurations that don’t have their own devoted control buttons.

The back display is actually made up from two LCD panels: the left-hand one is a normal color unit while a remove down the right-hand part is a desaturated place board. The backlight of the job remove can be converted on and off individually of the main display. The 2.36m dot viewfinder is very good, giving an in depth impact of the field and a fast-enough renew rate that you don’t really notice it. It can’t signify black as well as OLED shows, so it can’t quite coordinate their comparison but it’s well surrounded, so that it’s not extremely impacted by wander light coming in, even if you wear cups. A large three-position change manages whether you uses its back display, EVF or auto-switches between the two. The Quattro H contains all the features you might expect, such as level gauge, ‘thirds’ plants and a histogram. Pushing the display key periods through the available options and you recalls a different display establishing for the back board and the viewfinder.

Landscape photography is, as you might anticipate, the SD Quattro H’s great durability. Good mild is where the digital camera’s indicator stands out. The details catch, especially when combined with Sigma’s Art contacts is amazing. The move to an ASP-H indicator (the biggest Foveon indicator yet), has all the benefits you might expect: access more mild, significance enhanced picture quality and the capability to use more of Sigma’s contacts nearer to their designed position of perspective. There’s a 1.5x plants way of use with APS-C-specific ‘DC’ contacts but the full 1.3X plants means that it’s more readily found wide-angle options when you need them.

I found the body fairly relaxed to hold, despite its weight and I was able to capture distinct pictures a long way below 1/equivalent central duration, indicating I had a fairly constant hold on you. The two main calls are well placed, significance it was easy to set the aperture and visibility settlement.

Metering isn’t as reliable as we’d anticipate from a modern mirrorless digicam and the stay perspective review doesn’t signify the ultimate picture lighting particularly well. The stay histogram also only seems to signify luminance information so it’s well worth verifying the play-back R,G,B histograms to ensure visibility for crucial photos, since there can be important variations between programs.

Although it has on-sensor stage recognition components, these are used as part of a multiple system and there’s a very obvious contrast-detection procedure that considerably decreases the overall concentrating procedure. This makes some kind of sense on this camera: its greatest promoting feature is its amazing sharpness and details catch so crucial concentrate is essential. It’s not quick, though.

Battery power seems excellent, thanks to a significant 14Wh battery, though I did are able to affect the on / off activate in my digicam bag, significance I found a rather warm digicam with almost no battery left, next time I tried to use it.

The adopting of DNG is greatly beneficial, though. It indicates the Quattro H can instantly be used in any current work-flow you have established. And, since there will be no picture top quality cost to doing so, it’s how we’d suggest using the digicam.

The main thing keep Quattro H back as a scenery digicam is its rather restricted powerful range. Shade separating is also a little bit of significant, such that you may find you need to modify the orange/yellow reaction, image-to-image, based on the topic. The standard for the price is amazing, so long as you can work within these restrictions.


The Quattro H’s slowly concentrate and frustrating low light efficiency indicates it’s instantly restricted for public photography. In addition, its dimension indicates it’s not the simplest of cameras to lug around and this dimension and its unique shape mean it’s not exactly discreet. The Quattro H offers experience recognition in auto-focus method but this indicates to be very fussy about what matters as a experience. Fortunately its manually-selectable AF point can become fine enough to place concentrate just where you want it, if your topic is individual enough.

The digital camera’s obvious weak point in identifying color in the yellow/orange part of the variety sometimes required a little modification of along with reaction to generate excellent skintone results. These were very different to the improvements we’d designed for other test photos, so it’s something you’re likely to need to modify on an image-by-image (or, at least, subject-by-subject) basis.

If your photography goes away from the unforeseen mild and need for impulsiveness of public taking and towards more official, presented photography, these issues ebb a little. The production of a hot shoes and display synchronize outlet mean it’ll gladly work in studio room configurations where you can provide plenty of mild to the indicator, again allowing you to get the most out of it. Unfortunately I did not get a chance to capture with the company’s wonderful but de-heavy as terrible 85mm F1.4 Art, as a 110mm comparative lens appears to be charming for headshots.


You can probably provide the public and scenery tests that the degree to which the Quattro H will do the job for journey photography relies on what kind of journey you’re trying to do. Its battery lifespan is fairly reasonable but it’s fairly slow to focus and is also relatively large as well as to carry around. All of which considerably matters against it in terms of holding it everywhere and being able to reply automatically to surprising attractions.

As you might anticipate, activities digital cameras isn’t exactly the Quattro H’s milieu. The slowly concentrate and slowly taken create periods get rid of it almost entirely from concern (though Sigma does create some nominally sports-friendly lenses). While hypothetically it’s possible to capture activities to some level with fairly much any digicam, it’s clearly not the organic play area of the SD QH.
