Ever since the DP Merrill generation, all three cameras of the DP lineup have been equipped with the same hardware – in other words: sensor, image processor, display, memory interface and battery. Therefore it is worthy to take a look at some reviews of the DP2Q, even though you might only be interested in the DP1 Quattro.
The unique selling point of the latter is the 19mm f/2.8 (28mm FF equivalent) wide-angle lens, which makes the camera very suitable for cityscapes and landscapes. According to test reviews, the 19mm f/2.8 of the DP1 Merrill performed the worst of the three lenses – good for a wide-angle lens but it somewhat behind the outstanding 30/2.8 and 50/2.8 of the DP2M and DP3M. Sigma has taken test reviews quite seriously and thus treated the DP1Q to a newly designed 19/2.8. Whether the new lens is actually better than the DP1M one is something you will have to decide for yourselves. 😉
Reviews and comparisons
„So once again, it’s a case of image quality to the rescue for the DP1 Quattro – the 3-layer Foveon technology really does deliver a different look to cameras with Bayer sensors, a look that we like a lot. Only you can decide if this is enough to persuade you to splash out quite a lot of cash for an undeniably quirky, pared-back camera with a fixed focal-length lens that is really only suited to a slower, more considered approach. If that sounds like your cup of tea, then you won’t be disappointed by the breath-taking images that the Sigma DP1 Quattro is capable of…”
“Ultimately I can’t recommend the DP1 Quattro to a broad market, but if you love the look of the images and can live with the caveats and without the frills, it could be right for you. I can easily see a small but passionate group of photographers for whom it will appeal greatly. Just be sure to understand exactly what it can and can’t do.”
“The Sigma dp1 Quattro delivers some of the most detailed, crisp and sharp photos available, with excellent colour reproduction, although there are some image quality issues with JPEG images. Like previous Foveon cameras, the dp1 Quattro delivers stunning pixel level detail, great if you want to enlarge pictures, or view at 100%. There are however some drawbacks, which are now expected with Foveon sensor cameras, namely that as soon as you increase the ISO speed to ISO400 or above, then you will begin to see a lot of noise in images, and as a result we would recommend that you not use any ISO setting higher than ISO400. If you love the look of the images from the Sigma dp1 Quattro, then the price of the camera is quite reasonable, similar in price to many other large sensor prime lens cameras when they were first released. For those that have previous versions of the camera, the image quality improvements would make the new Quattro camera well worth investing in.”
“The Sigma dp1 Quattro is a camera with niche appeal, and with some issues. Its wide-angle lens is appealing to landscape shooters, and the amount of detail that the camera is capable of capturing is simply outstanding. At low ISOs it’s on par with high-end full-frame and medium format systems in that regard. But it’s not a camera that’s well-suited for shooting at high ISO—we don’t recommend pushing it beyond ISO 400—and it’s slow to use. Its JPG output is excellent at lower ISOs, so you may be able to skip Raw processing, but if you do prefer to work with uncompressed images, you’re going to have to deal with a Raw workflow that’s hobbled by very clunky software.
If you’re willing to work within its limits, the dp1 will reward you with stunning images. But there are just too many caveats for us to wholeheartedly recommend it. If you love the 28mm field of view, give consideration to the Ricoh GR as an alternative. It’s less expensive, small enough to slide into your pocket, quicker to use, and it also features an APS-C image sensor; you won’t be able to squeeze the same level of detail out of it as you can with the dp1, but its images are still very printable. Our current Editors’ Choice for premium compacts is the Fujifilm X100T; its low-ISO image output doesn’t match the Quattro series in terms of detail, but its 35mm f/2 lens, excellent low-light performance, and integrated hybrid viewfinder make it a more versatile camera.”
