IDEA: Take a basic 14mpx P&S, say an Optio S1. Remove the expensive zoom lens, focusing mechanism, etc. Replace with cheap C-mount, upgraded with A-type contacts -- call it CA-mount. Release line of Cosmicar lenses in CA-mount, with option of using manual-aperture C-mount 8mm-cine lenses. Sell body for US$200 (B&H price for standard S1), new lenses for US$50 each. Conquer the (small gimmick) world.

That's quite an idea. I don't think I'd buy one, but if you would... Really though, why don't you try it?

OK, pardon me for a stupid question, but what does it mean that it has a 1/2.3 inch sensor? I remember reading years ago that this nomenclature usually referred to a much smaller sensor than math would dictate. For example, the Panasonic 1/2.5" sensor had a diagonal of 7mm.

I plan to. Sort of. Not by manufacturing them (which was what I was suggesting -- sorry if I didn't make that clear), but... I not-too-long-ago bought a DIGITAL CONCEPTS (Sakar) 5mpx P&S off the bay for US$5 shipped, just because it has a fixed 7.58/3.2 lens. Cruddy little thing, lousy IQ, but it was cheap, and I got it to try to mount a B&H Filmovara 15-25/1.2 lens, for which I paid a whole US$1.15 shipped. Now I need a D-mount and some time...

The fractional-inch notation is left over from the days of image orthicons (TV camera tubes) and relates to the outer diameter of the tube, not of its active sensing area. Here are the sensor sizes of the most common fractional-inch standards:

1/2.7" -- 5.27x3.96mm, d=6.6mm
1/2.33" - 6.16x4.62mm, d=7.7mm
1/1.8" -- 7.18x5.32mm, d=8.9mm

Wee bitsy thangs, eh?

So let me get this straight...

The K-r has better image quality (An assumption since the Q has a smaller sensor)
The K-r has a faster frame rate
The K-r has a faster minimum shutter speed
The K-r has more lens options
The K-r has an optical viewfinder
and the K-r is cheaper?


Can anyone explain this?

PS I'm sorry if I'm overlooking any major details, I just quickly read the overview page.
size matters

Yeah. Unfortunately, I've had a kidney stone bigger than that.

No, I took you right. That sounds like a fun project. You'll have to post pictures, etc. once you get it put together.

The image quality could be okay. I use a Sony HX5V as a knock around camera which uses the same sensor. Here are photos with that camera of the KISS show.
