Patent Fun
I like to lead with the following, I am the worst reader of patent language on planet earth.
I've been sent an email explaining this patent.
“The image pickup element vibrationproof circuit 172 cancels vibration of an image by moving the image pickup element 127” and “Here, an image pickup element vibrationproof mechanism 171 connected to the image pickup element vibrationproof circuit 172 shifts and rotates the image pickup element 127 in the direction to cancel shakes of the image so as to prevent the resolution of the image from being lost as the image rolls.”
Is this in body stabilization that works together with in lens stabilization? The language of it seems to suggest so to me.
Also notice the GPS circuit, Digital TV Tuner and Wireless Communication Circuit.
What say you?

As a general rule, if you get two feedback systems that try to regulate the same thing they tend to interfere and build up oscillations. This is not limited to IS.
If you really really want both systems active, then make sure that one is a slave of the other.
It might be that, say, a generation 3 in-body IS is more effective than a generation 1 in-lens IS. In that case you want to use the in-body IS.
The easy way to set this option is to set the IS switch on the lens to off.
So you really only need a switch for in-body IS on or off, and the in-body IS will automatically turn itself off if it finds an active in-lens IS.
each pixel should might have had its own micro-lens iris that can open up or close down independently so as to minimize blown out highlights & dark shadows.
Actually the full-frame expensiveness is still a common myth, even if some use 300mm wafers since 2001-2002. Yes, the area and the consequent yeld still makes it about four times more expensive, but the area alone makes a difference from 100-150$ to about 400$. Under no circumstance is there a justification for more than 1000$ markup, even if you account for a grossly overstated manufacturer profit.
And yes, sorry for my English; I’m not a native speaker.
Also in a cheap full frame camera they could increase the yield by using slightly dodgy sensors.
Sensors that would hit the reject bin if they were for a 1 series camera, but good enough for a Rebel.
Sony does this with it’s video cameras.
