Is this what they are calling the new sensor?

Sony ExmorHD 16MP

good detective work

Also interesting:
Sony Global - CX-NEWS

Back-numbers have lots of sensor discussions too:

the image is just a joke of a chinese pentaxian,hoho

I heard that this was a real picture.

Any rumored specs on the K5 yet?
AF points, iso performance, flash system

Yes, many of the correct specs have been posted on various threads recently in differing places.

Basically it's the best of the K-7 with much more crammed in

Flash system is the major unknown at the moment

none of my sources are able to get any decent info on it.

anything specific like how many AF points on the K5?
the Nikon rumored D95 will have 39AF points and an
improved ISO performance at around $1200

No idea specifically about the AF points but, there apparently will be a surprise in relation to the view finder, something which Pentax apparently has had a patent for 2 years on.

Apparently the sensor will be the same as the D95, the 16mp Sony that's already been mentioned.

AND yes I do say apparent a lot

but until I see the official announcement it's still just speculation.

I`m sorry but why the **** does this thread with obvious fake photos still hangs here while Falconeye's thread has been moved to off-topic?

Thanks for the link.

I wonder whether the "Column-Parallel A/D Conversion Technique" is all good news. It seems to be there to increase readout speed but I wonder if it could affect noise in a similar way the unequal alternating green photosites in the Canon 7D do.
Sony make sure that different transistor offsets are cancelled out by using the difference between "reset pixel level" and "exposed pixel level" but if the transistors have slightly different gains this still has to be compensated for.

One of the advantages of CCD is that a single A/D converter is responsible for all of the pixels, so there is no need for calibration, balancing, matching, etc. Can the Sony "Column-Parallel A/D Conversion Technique" achieve the same consistency?

Also, I'm not sure of whether I'm a fan of on-sensor noise reduction. It may be exactly the right place to combat some noise at the correct level; hopefully it isn't used to produce RAW data where some choice about how to remove noise has been taken away from the user.

Does anyone have insights into the new technology?

Wasn't that one of the rumors for the K-7 as well?

Dont know, I had nothing to do with photography back then.

Well the source on this one seems to be very credible and has corroborated with another source on other things so I trust it.

Then again will see next month

Oh, please ...
Don't say it will have an electronic viewfinder?

Please don't!

This would reduce my interest in this camera by 100%.
