100% Bingo! I Derived Exactly Correctly for the 645D Actual Sensor Size!

One year ago, I made my calculations and guessed on the 645D sensor size. Some people did disagree much at my Blog and also elsewhere on the net, but now it is proven today that I did guess right and correctly for the exact figures, 100% correct! =Victory= :-D

Just see the official announcement that has just been published:-

http://www.camera-pentax.jp/new/news05/index.html (645D Product Preview News Vol. 5)

Quoted, "新製品では44×33mm大型CCDセンサーを搭載。35ミリ判とは世界が違う描写を実現するPENTAX 645D。"

Well, even Pentax reps at the last year's Japanese PIE said that they could not tell at that point, which I also reported.

So, anyway, let's simply wait for this "4433D" (which this name I gave to the 645D one year ago!), there is only one day to come!

Or.... it could be that Kodak never changed the dimensions since the 18mp sensor. See: http://www.dpreview.com/news/0503/05031603kodakka...
Kodak has today issued a press release which reveals a little more information about the sensor used in Pentax's yet to be fully revealed 645 medium-format digital camera. The sensor is named the KAF-18000CE, it has 18.6 million total pixels producing an 18 million pixel final image. Pixel pitch is 9 x 9 µm, no other specs are currently available but if we assume a 4:3 aspect ratio we can guess the total pixel size to be something like 4992 x 3744 which would make the active sensor area approximately 45 x 34 mm (a 1.3x FOV crop for a 645 medium format camera).

APPROX 45X34 OR in your case 44X33...... Seems someone else beat you to the ciphering...... ;)
The sensor size 44 x 33 of the 645D was indeed on the net long before RH made his crystal ball math. So that back padding of RH is somehow awkward.
