From foveon speak to maybe Olympus speak :)

U know how Sigma/foveon came up w/ a 45mp sensor, this Olympus patent does it so much more differently using the 16mp sensor to get a 40mp sensor..

http://www.43rumors.com/japanese-olympus-patent-shows-e-m5ii-new-sensor-shift-tech/

There is a rumor that this will be in their em5mk2 using the same 16mp non-phase detect sensor as the original em5 as the base for this.

When I first heard about this about two weeks ago, I thought maybe it could be a way of doing a pseudo foveon, but now seeing the patent, not sure now.

Not sure how well this will really work for objects that themselves are vibrating or moving fast.

Gary, do you think the resulting image would be identical with the ones taken with an actually physically larger sensor?

Or is this just to bump up megapixels? In which case I do not see that a lot of people would need it.
 
I was interested at first, then not so much. Reason is that if the camera sensor shifts to take four separate successive photos that are then combined, then you're going to have to quadruple the amount of light getting to the sensor to expose properly. Hasselblad has announced very similar technology in a couple of their new bodies, IMO makes more sense for a Hassy since it's most likely being used in studio on a tripod anyway. But hey they might have some sort of interpolation trick up their sleeve that we don't know about

The bigger the sensor..the bigger the surface area..which means better heat disapation.. Lower noise as u crank up the iso because there is better heat disapation is what I believe is what one of the problems may have been. The sensor size is maybe around half of apsc let alone ff.. The dynamic noise and high iso capability i am guessing is about where the base m43 sensor is capable..w/ of course this magic increase in mp due to this shifting of the array going on...

I think there is going to be another mp war that is going to happen myself. Rumor of a 50mp ff sensor from different manufacturer later in 2015.

For myself..
- about 16-20mp in Bayer or xtrans array sensor is just fine for my normal needs
- I am even happy w/ the 5mp size of the Quattro small raw
- the only reason I c for going higher is for myself is
-- if I want plenty of crop headroom
-- 24f2 prime lense plus a enough mp so that I can crop to 75fov perspective and still be able to print 11x14 max.

Actually, this one I am really not interested enough to be first inline.... I will sit this one out. Issue that effect electronic shutter today, maybe the same that will effect this new tech.

I agree, it is probably better in the studio environment.

AFAIK Hasselblad already does this a long time in some of their backs. Don't even understand why Olympus got a patent on this.
 
Dpreview had an account of the sensor shift in the Hassy:

If the oly is similar, does this have the wow factor to induce upgrades? At the moment I'm not sure I see the benefits (but I'm sure they'll be other ergonomic tweaks too).
