We are all anxious to have approval for the decisions we make, validation I suppose is the buzz word. But. When I think about it, I would never make a large time and $$$ decision based upon what web sites write. None of the photographers I know would either. So who does, and what are they looking to discover in a review. I imagine it's bench tests, comparison images, technical info and conclusions. This is where reviewers shine. They know their market. Their market has complained long and hard about missing shots due to shutter lag (slow focus) and slow write times. To have a new camera bring these exact same things to them just won't do.
This camera brings back a feeling of quality in images that is becoming lost. I get the most enjoyment from my old folding cameras. Medium format with outstanding 4 element german glass and all of the modern conveniences of the 1940's (none). They don't even take batteries. They're nothing at all except IQ
In 1971 after saving for over a year I bought a brand new Nikon F. It has a center weighted meter with a needle showing in the viewfinder. Completely mechanical except for the light meter I used it for 30 years. Now my digital Nikon does everything from focus to shutter setting to auto iso etc etc and shoots 10 or so RAW images rapid fire. If I'm missing a shot I'm just not facing the right way. The images it produces when manipulated slightly are wonderful. As proof I point to the 5 star images I have cataloged by Apple's Aperture. I bought the DP1 because I was hoping it would be like the Nikon in a small package and indeed it is. The user functionality I expected is perhaps more like the film Nikon and surprisingly so is the image quality. So it is like the Nikon in a small body but the old Nikon.
Someone in one of the forum threads mentioned that there is more to a camera than IQ. It doesn't really matter if the writer was serious, it's a great question. I think the answer is situational and photographer dependent. Action shots, while life goes on all around, An "OK" IQ in a great users camera is perfect. Other times though it's all about the IQ. Spend thousands on glass and use the equivalent of expired film??? Nope!
As an example. I made a photo book of a week spent with the grand daughters. Aperture makes this quite easy and the result was wonderful. Now I've started to pull together my 5 stars, looking to make another book. After several weeks with the DP1 though I'm just not happy with altogether too many of them. The IQ on digital just wasn't there. I didn't see that clearly because my images are either DSLR or film which is scanned and digitized.
The DP1 reminds me of what I've been missing.
