What do you guys think? Hope my idea isn't too wacko... for an indoor/lowlight use pocketable (see note below) camera with a standard prime lens...
Resolution: 6 or 8 megapixel. Option to pixel-bine to 1/2*1/2 or 1/4*1/4 to get a couple stops higher ISO at same noise level. (quick question... would it be possible to have 24mp (with, for example, 2-stop (or however it works) lower high ISO performance, then pixel bine, if done properly, to, say, 6mp, and get same ISO performance at 6mp as if the sensor natively had 6mp?)
Sensor Size: APS-C
High ISO performance: I'm thinking topping out at ISO 25600 at 6mp (while expecting similar performance to Nikon D3, with, if my calculations are correct, the ability to get ISO 102400 at 1.5mp (the lowest res from which I'd want to print a 4x6) with the same noise level that 25600 has at 6mp) (and, if you're feeling adventurous, maybe allow a few more stops above this, if you're willing to put up with the noise levels of a typical compact at its highest setting (for example F100fd at 12800))
No mirror ; either has EVF or P&S-style OVF. Definitely has LV
Lens: 30mm F/1.4 (give or take a few mm, if lens could be faster (up to F/1.0) it'd be nice, but it'd probably push price over $400-500 or so.)
Manual controls: separate dedicated dials for aperture, shutter & ISO ; live RGB histogram on LV display
LCD: 2.5" (give/take 0.5") rotating like A6x0 series Canons
Movie Recording: an afterthought... but wouldn't be surprised if whoever built this camera included it
Burst shooting: limited only by speed & capacity of memory card, also taking into account autofocus speed between each shot. Ability to use burst mode without having to hold shutter button down would be a huge plus (basically combine intervalometer with continuous shooting or something like that.)
When I say pocketable... I'm thinking something similar in size, or smaller than, a Canon SX100 IS, G9, or A650 IS, all three of which are smaller than my S1 IS, which is toward the upper limit of what I consider pocketable.
I'm sure nothing like this exists yet, but how difficult would it be for a manufacturer to come up with something? Closest things I know of are the Sigma DP-1 (has near APS-C size sensor, but a wideangle slow lens) and the Panasonic LX3 (has F/2.0 lens (still 1 stop slower than what I'm thinking this camera would have), but small sensor.))
Would it be possible for a camera with those specs (APS-C sensor, ~50mm equivalent F/1.4 prime built in, no mirror) to be relatively compact? If it's possible to have one of those, what's the chances of it costing under $400, assuming it's not a one-time special order, or if not what would the typical retail cost be? more like $600 or something like that?
Quick ?... would it be too much to put in a full-frame sensor with a ~43mm F/1.4 prime, in a pocketable (read: smaller than S1 IS) body?
This isn't a "which should I buy" question.... as I know in the form I'm looking for it doesn't exist... just wondering if it's possible, and if so, why doesn't it exist?
