Sigma DP1; A Compact “Full Spec” Camera Page 2

You can shoot in any number of modes, with Program being interesting in that you can shoot with Program Shift--in other words, you set it on P and toggle the back buttons to shift the equivalent exposure in any combination you desire. As with aperture- and shutter-priority the numbers read out at the base of the LCD. Manual is a bit more cumbersome, but it's there if you want it, working the toggles until the +/- readout hits 0.0, or any over- or underexposure setting you want. There is an AEL (autoexposure lock) button that makes reading and holding highlight areas easy enough.

The shadows were getting fairly deep toward sunset, but all I did was read from the brighter sky and lock exposure using the DP1 exposure lock button, thankfully not linked into the shutter release button. This made controlling bright highlights easy, as does the choice in metering patterns.

Autofocus is center-point priority unless you change it to one of 9 points using the Menu, but I found it easier to use the center and then lock. Manual focus is also possible, but frankly the LCD outdoors can be difficult to read so I stayed with AF. Indoors, manual is much more useful, if desired.

You can choose aperture-priority for shots such as this where the depth of field becomes critical. While there is no depth of field preview you can be fairly sure that shooting at the minimum aperture of f/11 will get you critical sharpness when needed.

Once shot you can set the review time to various intervals and also get full image information by pressing the Display button. There is no highlight overexposure warning option (the "blinkies"), something I would hope is added the next time around. There is, however, a histogram display that can be helpful.

Colors out of the camera are excellent thanks to the three-layer Foveon sensor, something quite unique to the DP1 among all compacts. Adding a +1 saturation in the camera brought froth even more colorful results from these Florida scenes.

I worked with the DP1 over the course of a few weeks and found image quality to be excellent in both the Fine JPEG and Raw modes. As of this writing there is no Raw converter in Lightroom or Adobe Camera Raw for CS3, so you have to process the Raw images using the Sigma software. I am told by Sigma that they are working with Adobe to get this straightened out. My advice is to convert using the software and do the rest of the work in your image editor of choice.

JPEG images even of the largest size wrote quite quickly and efficiently, but the Raw writing time in the camera seemed excessive. Switching to a fast SDHC card from the standard SD card I had been using overcame this problem, so that's what I'd recommend for Raw shooters.

You can shoot in monochrome or sepia in the camera, if desired, which is pretty much moot when using Raw, which you can convert later, but is fun nonetheless. This Fine JPEG shot was made at ISO 400 using monochrome mode on a foggy, snowy morning in Taos. Reading was made and locked toward the brighter part of the sky, then the shadow areas were opened up in CS3. I saw no appreciable noise in the shadow areas even when they were lightened using Curves.

My main critique is the LCD, which was a tough read in daylight. One way around this is to set the LCD brightness to high and screen contrast to low, which helps somewhat. Because the camera lacks a built-in finder, composing with confidence, and seeing the results after the shot, and even reading the settings became a challenge. A recent firmware upgrade (available after my test period finished thus not tested) offers a grid lines for the LCD if desired, which might improve things somewhat. I advise, as did the fellow I met in the taqueria, to get your hands on the optional VF-11 Viewfinder, which you can slide into the hot shoe on the camera. This of course eliminates the possibility of using Sigma's accessory flash, but does not stop you from using the built-in flash.

The pattern meter in the camera did an excellent job in all sorts of lighting conditions. The sun was bright on this pond and fresh snowfall field, yet the meter kept it all under control. You just have to have faith with this camera's capabilities, as it was tough to make a judgment in the field with the LCD due to bright sun conditions.

So for me the DP1 is a bit of a puzzle. On the one hand it is a very versatile camera that produces excellent quality images and is eminently portable. There are many options that are akin to SLR-like cameras. The fixed focal length lens might seem limiting at first, but this is something you get used to, even enjoy using. But the LCD screen is problematic, and in bright daylight got in the way of making compositional decisions and even exposure settings. This is not unique to LCD-finder cameras, but here is one problem that diminishes an otherwise excellent traveling companion that produces superb image quality.

The Sigma DP1 has an MSRP of $999.
