10-10.5 fps - no problem. Sony 12 MP sensor can 4.5-5.0 fps (specs - 5 fps).
That's not what I mean. I'm just saying people are assuming this cannot be in the next K-7, because they don't think Pentax will make a shutter capable of 10+ fps. I'm saying just because the sensor can do it, doens't mean the camera necessarily will be able to.

The Sony a700 sensor has 10.3fps but limited to 5fps in the a700.
The Sony a900 sensor has 6.3fps but limited to 5fps in the a900.

The maximum transfer capacity of the sensor is not the maximum fps in the camera.

There are at least 30-40 shutter makers.
Shutter makers offer various types of shutter.
The main maker is COPAL.

If Hoya buys such shutter, the camera can.
Photo brands don't produce shutters.

Show me, please, specs for A700's sensor.
D200's 10 MP sensor can 5.57 fps. D200 can 5 fps.
6 MP sensor can 3.3 fps.

Thank you. But Sony can makes verisons of sensors under another brand's demands.
IMX021 is not 100% A700's sensor. Have a look at ICF - 54 Mhz.
It's version of sensor for D300. IMO.

A700 can 4.9 fps, D90 - 4.5 fps, K-x can 4.7 fps. I think ICF - 27 Mhz.
Nikon D300 can 8.0 fps.

Well, is difficult track all the Sony CMOS sensor in DSLR, but, probably be something like this:
-IMX021: a700/D300
-IMX038: D90/D5000 (720p video support)
-IMX0??: a500/a450/K-x (12MPx extended ISO setting), 720p video support
-IMX0??: a550 (14MPx extended ISO setting), probably 720p video support

Probably the IMX038 and the K-x sensor are a modified version of IMX021.

The first CMOS sensor from Sony in a DSLR was the IMX007 in the Nikon D2X, and the same technology was used in the APS-C 1.7X size CMOS sensor on Sony R-1, but I donīt remember the model number.

The 10MPx CCD in D200 is different to 10MPx CCD in D80/K10D/GX10/a100/a200..., the D200 sensor is the ICX483AQA, almost the same in the others DSLR (ICX493AQA) but with 4 output channels instead 2.
The D200 sensor reach 5.5fps and the D80/K10D 3.3fps.

Remember what happened last time they increased the read out (K20->K-7). The IQ, at least at high iso, took a small step back.
It was more a matter of NR taking a "step back".
The K-7 starts NR processing in RAW at higher ISO's than the K20D, this means that the K20D in practice does more NR processing to RAW files than the K-7 (in the meaning - uses NR in RAW at more ISO speeds than the K-7) and this is the main reason for the K-7 appearing as noisier than the K20D. Less NR = more noise.

This new sensor has NR processing on the sensor itself. We don't know yet how this performs.

I realize it is off topic here, but why the hell would anybody need 11 fps?? :ugh:
Because Canon and Nikon does it.
Many buys DSLR's after the technical data sheet.
It is not a question of "need" here, in the primal sense of the word - "need" as you can't survive without it. But it is a "need" to have the best technical specifications so one can look at the tech spech and say "Aaaah, what a camera you have".

I don't know how they really do, but I think that at 10 fps it's really hard for camera to AF-C.
So what I think - 5 fps in normal flip-mirror+AF mode and 10 fps with mirror-lockup (only shutter works, no mirror) and showing last frame on LCD (because of high burst rate it'll look like live-view).

People on this forum often state that a FF DSLR from Pentax would only have a small market.
I would think that the market for those who require 10fps would be no larger!

Good point IMO but the perceived image of the company may be different.
