A copy of the atmosphere take place through a digital medium format 40 megapixel "645

That's what Google Translate translates the title of this news item on Yodobashi's web page translates to

I think it means that the 645D indeed went on sale today!

Launch brief

Pentax held a brief in Tokyo on the 9th, before the sales started today.

This article on DCWatch goes into the history behind the 645D launch - http://dc.watch.impress.co.jp/docs/news/20100610_373415.html

One of the reasons for the delay was that they wanted to get the K-7 out of the door before finalizing the 645D.

Among other things they mention that Pentax tried a CMOS sensor with live view but decided that the better image quality offered by the CCD was more important than offering a live view.

It seems as if the sensor assembly can accept a low-pass filter that might be included if there is a demand. It would be rather expensive though, that's why it is not there now, if I understand them correctly. Hopefully, this makes more sense to you…

They offer several reasons for adopting the SDHC card and not the SDXC. The two slots can be used in several different ways, one RAW and the other JPEG, or one used as a backup for the other, just to mention a few.

The shutter should last 50,000 exposures, these are actually counted in the camera.

Costs were controlled by sharing about 10% of the components with the K-7, for example PRIME-II and the battery. This should give between 650 and 800 exposures, depending on the temperature.

The lens road map was not revealed in detail but the super-wide-angle lens shown earlier should come.

They don't target the professional or the overseas customer now. The order situation is said to be extremely good. Overseas deployment is depending on the establishment of after-sales service.

Nice to hear that manufacturer foresees such details. I wonder if it might be included only in future cameras or even paid to be installed at service, if needed.

This reminds me of Cokin-P. Only for sensors lol.

Hopefully, users won't force them to include this. In the MF world, it's been traditional not to do this and to do it in software (Phase One's software has a great antialiasing filter). And it gives you much sharper pictures as we learned w/ the K10D

Could you please elaborate about this filter and the better performance on the K10d. Is there a discussion of this anywhere? Thanks

RiceHigh provides an explanation, although take some of the claims about performance issues with a grain of salt.

Can you still find photozone's review of the K10D? Because the link from RiceHigh's blog post is dead.

I've always wondered why DPR found the K10D soft. I've always been very happy with the sharpness of its images.

Because of jpeg engine. Dpr likes ovesharpened canon-like rendering with no noise (even if it kills details).
