Sigma DP1x – A Pocket Imaging Marvel?

Sigma DP1x

I recently came across this camera for an extremely affordable price and decided, based on its almost cult status being capable of capturing superb images, to snap it up (sorry for the pun).

I was interested in discovering if it produced the kind of world class images it was purported to be capable of and also whether the frustrating elements of the camera – slow to operate, slow write times, slow autofocus and write to card, poor high iso performance, average build – were accurate.

To cut to the chase I can confirm that the images the camera produces really are superb with wonderful colour and sharpness. The 3 layer Foveon sensor – a Google search will provide a ton of information on the technical aspects if this device – is a significant departure from those used by the competition.

The DP1x captures colours nicely

The comments that it is close to a film camera in the way it resolves colours and more importantly the visual feel are, I feel, accurate. This performance coupled with the super sharp fixed 28mm (equivalent) lens means that its output exceeds that of my Fuji X-E1 and 18-55 lens which is no slouch in these areas.

But there is I am afraid a “however”. There usually is but the caveats to this camera producing  the kind of images that when you get them on your computer screen make you go “wow” are as long as your arm.

Get the camera in the right conditions and you will be amazed. And by right conditions I mean generally outside, on a bright day (without any sun on the screen as the preview fades dramatically in bright light), with low iso (200 or less), on a static subject and ideally with manual focus to get things just so. Oh and a tripod would probably help as there is no inbuilt image stabilisation.

Nice detail from the fixed lens/sensor combination

As stated previously if you can comply with virtually ALL of the above (maybe forgo the tripod if you can get your shutter speed up) then you will be richly rewarded with images that have a quality I think you would struggle to achieve with anything up to a Canon 5D Mk3. Not print as big as the side of a house quality but up to A3’ish with some tweaking kind of quality (and yes I have owned a 5D Mk3 and I am fully aware of the files it produces).

As for the build quality. It feels fairly solid but strangely light to me. Build quality is certainly not going to blow you away. It feels no better than a £200 point and shoot from the likes of Canon or Nikon and as the camera’s original retail price was around £600 then I think it will leave many disappointed.

I feel it handles this scene well

Operationally it is very straightforward which makes a refreshing change with a mode dial on top for “P, A, S, M” shooting, set up, video and voice recording (!?). The remainder of the settings are fairly simply laid out after pressing the menu or quick menu buttons on the back of the camera although these have their own quirks that have to be experienced to be believed.

So who would the camera be good for? I would suggest landscape and architectural photographers that want to produce world class, fine art prints sized A3 or smaller. Forget portrait photography primarily because the focal length does not lend itself to this type of photography. In fact I would forget any other type of photography other than the ones mentioned previously.

Incidentally, forget the video capabilities of the camera – I am at a loss as to why Sigma even bothered given the performance here.

I would love to try out the new Merrill DP cameras out to see if any of the niggles have been ironed out. Until then I will be moving the DP1x on as, for me, its quirks just about outweigh the positives.
