• Review on the Sigma DP2 Quattro



    Since everyone is just clamoring for an update on this, well, here it be.

    The good:
    1) Low ISO image quality is outstanding. If you are taking pictures of things that aren't just bright areas and dark areas, this is the best camera I've ever used. Really. Sharp and solid all the way across the field of view with great contrast. I pretty much always bump the contrast on shots at least a little bit but with this I left it alone.
    2) Does not transmit ebola to those who use it.

    The bad:
    1. The screen is abysmal. It has the shiniest coating on the back of anything I've ever used. In pretty much any sunlight you are blind. Further if you can see it the quality is terrible. I set up some shots off of a tripod and at 8X magnification the view was so blocky it was damn near impossible to make sure you were in focus.
    2. This is the slowest camera I have ever used. My 10 year old Nikon point and shoot is faster. You have to wait 5 seconds or so after taking the shot to see the histogram. I tried different cards but stuck with the one they supplied. 50 meg RAWs are annoying if you have no ram. And that is important because...
    3. For as good as the sensor is in a lot of situations, it is certainly not up to grade on dynamic range. In the B&W landscape below I had to bring up some of the trees about 1.5 stops and it was already starting block up. Now, the noise shown is not terrible and would look fine printed but this wasn't a huge bump in exposure. I would expect better when I bumped 4 stops on my A7R. And this leads to a problem because...
    4. The metering is just damn odd. It seems to really expose to the right to the point that I was routinely dialing in minus a stop of exposure compensation to keep the highlights from blowing. And because the dynamic range is so limited the blacks then would be gone. And when it is showing you the highlights are blown, they are really blown. Dialing them down in LR is not possible.
    5. As everyone expects, the ergonomics are just odd. It is balanced weirdly in your hand and is all sharp corners.
    6. High ISOs start at about 800 for this. 3200 is unusable. 1600 works in B&W and thinking you are Moriyama.

    The ugly:
    1. All of the above might be livable if it didn't require the use of their software to decode the RAWs. It will take about 30 seconds to a minute for each picture to be converted to a TIFF on an i7 processor computer. That is assuming the software works on your computer as it didn't on two of mine. This last point is so bad that I will make it known that I will point and laugh at you if you purchase one of these.

    If I can deal with it I'll put up a couple full size shots on Flickr. That sensor can be good in a very limited way but it is just not worth it.

    C/N Weird for the sake of being weird, the required software to undo the weirdness kills it.

      This is huge news: Adobe Camera Raw Update:

      Sigma
      dp1 Quattro*
      dp2 Quattro*

      (*) denotes preliminary support. Camera Matching color profiles for these models will be added in a future release.

      Hopefully it isn't as half-baked as the original Xtrans attempt was.
