The "I told you so" was about the ability of computers to handle the file size and the soon to be realized storage issue. While I agree with some of the uses, my advice is still, compose in the viewfinder. Personally I haven't found the need to consume large numbers of megapixels. My printer seems good with as low as 100dpi. I've read that the human eye can resolve 560 dpi.. some guys try to make a big deal of that. The thing is, the printer doesn't print 100 dpi. It prints dots that bleed together and form one consistent surface. There is absolutely no reason to assume that because the human eye can resolve 560 dpi, an image printed on an ink jet printer needs to be printed at 560 dpi. Unless the print is to look exactly like you were staring at the object. That's a preposterous idea and not in any way artistically necessary or desirable.
That's a great illustration of down cropping, I like that, I wish you had a K5 image taken off the same tripod set. I have to ask if the K-5 would have produced as soft an image as the cropped Nikon. I'm guessing it would but, I'd still like to see it before I proclaim it truth. I'd also note that if reproducing text, I might want a higher pixel count. But most of the time I want my images to look more like water colours than typeface.
If someone asked, I would certainly try a print at 50 inches wide. Currently we go as high as 33 all the time and there are absolutely no issues with dpi.
In any case, thanks for posting those. All information is appreciated.

I went through the same thing with my K20D. But, I wouldn't buy a camera based on it's ability to shoot movie like sequences. I assume what your saying is the Nikon is better than the K-5. I've done it enough times with a k-5 to know it can be done.
The following picture is the end of an 8 shot sequence taken in about 2 seconds, the dog is coming at us full speed "attacking" his ball. In The whole sequence the dog is in focus as he moves through the frame. My buddies old film Nikon would have taken 12 pictures in the same time period, equally in focus. But I don't need 12, I don't need 8, I would have been happy with 4, I needed 1. So most of the time what you're talking about is.. do I want triple overkill or double overkill.
And more to the point... you can get the shot you want with a k-5 and it can be just as good or better than the one you take with your Nikon, in the same circumstances. The guy pulling the trigger is still more important than the technology.
I would never argue that the Nikon advantage in autofocus hasn't been going on since way back when I was shooting film. But, the thing I find most irritating about these types of threads, is people telling me they can't do on a K-5, things I do on a regular basis. And the other thing that irritates me is, Nikon has had this advantage since the days of film, I'm talking 25 years ago. If that's what you want, why did you buy Pentax in the first place? I wouldn't have if that type of sequence was important to me.
It's all about what is good enough.
