Sigma DP2s - Test Shots - Exposure Evaluation

By Cliff Smith



Our Score:


Here are some general test shots to help evaluate the camera's overall image quality, including dynamic range, colour rendition and the zoom range of the lens. Some pictures may be clicked to download the full size original image.


The DP2s has a non-zoom lens equivalent to 41mm.


Dynamic range is superb, with both shadow and highlight detail even on this midsummer day in full sunlight.


The fixed focal length makes you work for your compositions.


Colour rendition is simply stunning.


The wide maximum aperture and large sensor give excellent control over depth of field.


This is a 1:1 crop from the image above.

Would you pick one of these up for yourself Cliff? Maybe if you saw it cheap?

Possibly, but with the state of my finances at the moment it would have to be very cheap. I'm hoping to have the new Sigma SD15 DSLR in for review soon; I'm keen to see what that can do.

I'd be interested to see how this compares to the sony nex-5 which comes with a 16mm pancake lens as part of the kit though it's focal length a wider angle equivalent to 24mm

I can understand if Sigma is wary of relinquishing any control but since their cameras are so unrefined apart from the fabled sensor and lens, I would say that their cameras are screaming for some kind of high-powered partnership with another big camera maker.

@Cliff - Know the feeling all too well..

@Hedgeporker - I'd love a Ricoh/Sigma mash up! :D

@Cliff - The SD15 needs to be really on the ball with the price they are after!

Does anybody know if Sigma will update the Foveon sensor at some point?

I love the sigma cameras and would dearly love to own one, but always felt it just needs a few more megapixels and that sensor would be truly great!

My personal camera fantasy would be a Pentax K7 with a full frame Foveon sensor. I would also like to stick one in a Leica but that’s a different story. . . .

I agree with Hedgeporker, if Sigma is on the ball strategically they should be looking for a pertnership with one of the big dogs who could design and build a super compact around the sensor and lens.

Noise is one thing, but would anyone care to address the significant color shift between the ISO 100 and ISO 800 examples? If image quality is the DP2s' raison d'etre (and for me that includes glorious color rendition) then aren't situations that significantly compromise IQ worth special notice?

robert e - a loss of colour saturation at higher ISO settings is common to most digital cameras. It is a symptom of increasing noise, or rather a reducing signal to noise ratio.

@joose - Ricoh/Sigma mash up was also in my thoughts, but my feeling is that they will end up bickering about whose name gets to go on it precisely because they seem to be on rather similar frequencies. Or maybe Ricoh could just start knocking out a line called Ricoh Sigma with body and OS from the former, lens and sensor from the latter? I like the sound of this more and more . . . :D

@Hedgeporker - They could simply make a module for the GXR. Test the water so to speak.


July 1, 2010, 8:25 pm


GXR probably doesn't have the broad appeal that would make the water-testing commercially viable. A GR Ditital Foveon however . . .

Thanks, Cliff. It's not that the effect is unexpected, but that it shows dramatic in this sequence. Perhaps the jpeg engine is partly to blame and it is less apparent in the RAW workflow?

Hi Cliff,

Just a question... you're the same who made the dp1x review... they are supposed to be more or less the same stuff, apart from the lens (what you say about sensor it's true for one and the other, I guess)... but you are much more negative with the dp1x then with dp2s. I was wondering about buying the dp1x, cause of the wide angle, but actually I'm not so sure anymore. May you explain me better what are the differences you noticed that made you change your mind about sigma stuff in so short time? It seems dp1x has worst low light performance (Iso and focus), worst working speed... what more?

Thanks a lot,

@PV: Well, for one thing Cliff didn't review both cameras. For another, they both get the same overall score. For a third, the dp2x has had two years worth of developments that have been added to it, so you'd expect it to be a better camera.

As to whether to buy a dp1x, I'd suggest it largely depends on whether you can get it at a good price.

@Ed: Cliff did review the DP1x in Nov 2010 - you are referring to the DP1 from 2008. The DP1x did much worse than the DP2s in Cliff's reviews. In particular, the key reason to buy the DP2s was its image quality, but Cliff seems to suggest the DP1x quality is more varied. I would be interested in knowing if there is a big difference between the two or if it is simply that the competition have improved quite a bit in 6 months.

A key consideration is that now the DP2s is available for £400 which is a bit more manageable, but the DP1x is about £500 - the same price as the Panasonic GF2 with lens.
