Sigma DP1 review sample:Sigma DP1 Review: Pure Images from Your Pocket

*****ERRATUM*****

It seems that our translator made a huge mistake in this article, INDEED, the DP1 is not a DSLR, sorry for this "bad" translation from French to English.

Many people will come to covet the Sigma DP1, and this is understandable! When you see the picture quality produced by this little digital camera, you should have no reason for surprise. Clearly, 1 pixel equals 1 pixel! It ignores interpolations that inflate the number of mega pixels… Here Sigma is seeking clarity for the record!



Getting Started

The DP1 fits well in your hand, and with it you’ll appear less touristy than if you were carrying a conventional digital camera. Its rectangular design and lens cap creates a retro effect that some will appreciate, tho others may curse the cap as it hinders Lucky Luke point & shoot techniques… Clearly, this is a camera for those who are patient when taking pictures. Although it possess automatic modes, for a great finished product pictures should be taken in manual mode.

The DP1's design is well conceived and works well when using manual settings. I particularly found the manual focus knob to be very comfortable, and its wide 2.5" screen provides enough light for outdoor use, and a practical field of view.

Electronics

The Foveon sensor is IMPRESSIVE! Image detail is breathtaking when set at 100%, and clearly a slap in the face of the best reflex! I've never had a camera capable of this level of quality in my hands… The sensor's 3CCD technology is revolutionary. On the stroke we have actual pixels, not the interpolations provided by other sensors.

Some may scoff at the specs' 4.6 Mega pixels… Indeed! But these are ACTUAL 4.6 Mega pixels! When other manufacturers advertise 10Mpx, they’re really saying 2.5Mpx of Blue, 2.5Mpx of Green, and 5Mpx of Red… all this is interpolated to provide an image of 10Mpx. The DP1's Foveon X3 sensor's 4.6Mpx image is composed of 4.6Mpx of Blue, 4.6 Mpx of Red, and 4.6 Mpx of Green… the equivalent of 14Mpx when calculated as the others. Its 4.6Mpx, when extended to 14Mpx, provides an image rendering almost identical to a reflex.

Technology is not everything, we must also take into account the DP1's sensor is the same size as that found on a reflex… namely 12 times the size of those generally found on a camera!


All this combined, we can easily see that picture rendering is worthy, and may be superior to high-end digital reflex cameras.

Not everything is perfect…… far away…. Although the sensor is a great technological advance, the rest the camera is lagging and similar to digital cameras released five 5 years ago. Auto-focus is slow and imprecise (not considering the image freezes for an instant when focusing… taking a picture of something in motion is nearly impossible), long lag time between two shots, ignition slowness, forget setting ISO sensitivity too high…… etc. Use is really reserved for those who have the time to prepare their shot... Point & shoot aficionados should forget it.



The 320x240 pixel video format is simply ridiculous, and shows how behind Sigma is on this point…



The menus are clear, and their's also a certain freedom in manual settings.

Finishes and Accesories

No need feel careful when handling this camera, it's like possessing a handmade and robust device. Although the lens is excellent, I feel Sigma is fudging a bit... This is not really a wide-angle (it's advertised as a 16.6mm, but including the size of the sensor, it's really a 28mm lens ) and you will end up with an average image size… A shame because this camera is clearly designed for those who want to do something different… something artistic!

Accessories are interesting but far from essential… really for addicts.
