645Dn mini

So I have run around with the 645D for 15 days and I have come to the conclusion that it is really a fantastic camera. I will present some images in a few weeks that I made on this yourney with 645D, K-5, K-01 and Q.

The 645D is by far the superior camera. There are a few things that bug me about it.

From flickr: Flickr: HAMACHI!'s Photostream




So the design for 645D is clearly coming from 645N. The one thing that can't change is the focal flange distance between sensor and lens. But when it only futures a crop sensor of the current size (44x33mm) then there is no need for all the space that a full size sensor would take. The mirrorbox and shutter can shrink and take less space. There is no box for containing a old-skool film, so realley behind the sensor there is a need for the backscreen (unless it is on top of the camera).

I would like a cmos sensor that at least can produce iso3200 (or better iso 6400) and can take 2 fps. I would love the sensor from K-5 into this new 645Dn mini with a sensor size of 44x33mm and thus 64 megapixel. I would like it to have a SR system for handheld pictures.

Does anyone have an idea about how small the camera can be and giving everything that is needed to be a full functional 645D camera?

You want a Nikon D800.

Well maybe even a little bit bigger sensor. So I would even settle (if I could affort it) for a sensorsize of 48x36mm and with 76 megapixel. But a bigger sensor with any number of pixels starting from 40 megapixel would be great (bigger sensils are okay, like a sensor of 48x36mm with 48 megapixel).

I realize that a bigger sensor does make images possible (or more easy) that one cannot make with a K-5. So why not jump over D800. But making it more easy then 645D is (and a little more affordable if possible).

To share a set of pictures that I made with 645D and FA 645 300mm/f4 lens at the EC Beachvolleybal last week:

2FPS from medium format? Funny...I don't think any of the CCD sensors can do that...not even in the $50K Hassy/Phase1's :-)

I thought that speed was impossible from a 40MP sensor, but Sony's D800 chip design is nicely done...

Well that's why I think a cmos is a good step. The pircedifference (with D800) is also something to address since you need sales.

Sports with a 645? Dude, you really need to get a D800.

Surprisingly, but that did work out very good. It is a question of timing. I will show some results in a few weeks. I was at the EC Diving and behind me there was a D3s and a 1D Mark IV for the 1 meter board. So they took each 20 pictures I think for one jump and I only took one. I still have the one picture that you are looking for.

Over-assistance is indeed NOT an incentive to shoot right, haha
