A 26X zoom!! O mai gawd. When will the insanity stop? Will we end up with a 500 megapixel camera with a sensor like a pinky nail, and a 150X zoom lens plus 50X digital zoom?
Look, it's pretty useless, OK. Just ask reader and fellow blogger Ray. He has tried a couple of these super-zoom cameras, and all we hear is questions about why the pictures look like they're taken through a dirty plastic bag. (Update: I exaggerate... in good light and at short zoom levels, there are no problems.)
For good picture quality you need a biggish sensor, a short zoom at best, and no digital zoom at all. And you don't need anymore than 10 megapixels for prints and five for the web.
Update:
(I didn't even remember that Ray has the predecessor.) Ray says:
Here's a picture of my Pentax X70 on its Optex T25 tripod, in front of your web page on the monitor.
That Pentax X90 you show in the blog looks very similar to this X70, and probably is, except for a bit more of optical zoom. The right lighting has a big effect on zoomed pictures, I think... If the light's good, the results are much better - not so much noise in the images. I've noticed that for shots after dark, of lights or objects in the sky, there's a lot of noise in them. Shots in bright daylight come out much better. But I guess that's true of any camera, really...

That is true, only it's true in inverse ratio to the size of the sensor. These kinds of cameras look like they might have a rather big sensor, but it's really very small (less than ten milimeters to a side), which makes it not great for weak light. A camera like the big Canon 5DII, on the other hand, has a great big sensor (24x36mm), and you can hand-hold night-time pictures with it if you do it right (the right lens etc).
The downside is cost and size, especially for long zoom lenses, which will get huge.
