To be sure, it wasn't the camera I was looking for either. I think combining the 1D line was a huge mistake. I mean, isn't one of the main reasons they kept the camera at 18MP was to be able to shoot so quickly? Wouldn't a lot of studio photographers been a lot happier if they could have shot at half the speed but with much bigger images?
I hate it when somebody tells me "you don't need anything more than 18MP." I have heard that a lot. How do they know what I need? When working with a model, I certainly need 27MP much more than double digit frames per second. I was kind of hoping the new 1D would rival medium format. When I'm shooting sports I don't want full frame. It's an impressive camera, but I really think they only people it's perfect for would be like National Geographic photographers and certain kinds of sports on smaller fields/courts. It's just the wrong camera for me and a lot of others, as well, even though it has a lot of really sexy features.
While I'm painfully aware of all the MP addicts that equate overall image quality to MP count, there are certainly situations where the resolution is a necessity, not a "hey, I can't crop with only only 'x' megapixels" affair. My shooting needs prioritize dynamic range and high ISO performance over ultimate resolution, but that doesn't mean resolution isn't important. For instance, there are instances where I'll shoot shoot material for a brochure or editorial work, and later on down the road, the client wants to re-use some of those images for posters or banners at trade shows or other promotional material.
Additionally, I'm not sure where the 300 dpi standard comes from, but even in a small image, say 3x5, print much better at 450- or 600 dpi vs. 300. Perhaps it has something to do with the poor paper, ink, and print quality my editorial clients use, but I can easily spot the difference between shots taken by my 5DI and 1DsIII when printed at the same size in the same magazine.
In that regard, the 1Dx is an impressive machine, but I see it more as a 1DV than a 1DsIV. I really hope Canon has a high-res body in the works, because I'm not looking forward to selling all my Canon gear for a D800 if it indeed will have a 36 mp sensor.
