I pulled the trigger on a D200 today. The choice was very difficult as my intention was to check out, and probably buy, the Fuji S5. I spent a couple of hours yesterday at my favorite camera store, Ace Photo, in Sterling, VA. I had heard (and so had some of the employees) that some Nikkor and some Sigma lenses wouldn't work properly with the S5 so I drug in several of my Nikkors and Sigmas. They all worked perfectly. On balance, the color fidelity, dynamic range, metering, and exposure control were simply superb. Shooting indoors in a variety of situations yielded perfect results every time. Since it it was the first one the store had unboxed, everyone there wanted to try it and the reaction was the same as mine. The staff keeps an S3 around for various uses and so they had some expectations I didn't and none of us were disappointed. It appears to be a real winner. As I was chimping the results and comparing it to my D1X, an employee handed me a Pentax K10 with a 16-45/4 on it. The K10 has on board image stabilization and I must admit the results were so impressive I found myself considering it as a landscape camera or perhaps a dedicated camera for birds. Results generally equalled the S5 and it has a few bells and whistles that make it very attractive. This is a very impressive camera and I have alway maintained that Pentax glass is as good as it gets. Their MF lenses are unrivaled. By way of some background, I am a lifelong Pentax fan. All my user film cameras are Pentax (K1000, ME Super (x3), LX (x2), 645, 67 II) and all my digital cameras are Nikon. I went with Nikon when the D70 appeared and I was not particularly impressed with the Pentax *ist D at the time. When I left the store, my head was spinning with possibilities. As soon as I got home I went to DPReview and, using their side-by-side comparison feature, I looked at the S5, D200, and K10 again. I studied them for some time and then took a mental inventory of my Nikon glass vs my Pentax glass. I decided on the D200 for these reasons (price was not one of them): 1) the D200 has been around awhile and is a known quantity. 2) the S5 is still very new and, impressive as it is, I'd like to see a little time go by and see some more information about it before I get one. 3) As impressive and price competitive as the K10 is, all of my Pentax glass duplicates my Nikkors and Sigmas. That's OK but, good as it is, it's still redundant and not AF. If I rethink my equipment inventory I could probably make a case for selling selected lenses from each group and then get a K10 or two and begin using two systems.
