Tilt screen rationale

I figure all rumours need to start somewhere, so why not here. I was contemplating why the new tilting screen was designed the way it is. Here's what I think. It's actually feeding information to the ibis and has the ability (when turned on) to tilt/shift the sensor plane to enable any lens to be a tilt shift in all directions.

Easier explanation:

Tilting screens (like on the 645Z) can't pivot side to side.
Articulating screens (like on the K-S2) need to be flipped out.

The K-1's unique screen design addresses both these limitations

Easier, but much less fun.

There are some interesting ideas there. But probably not implemented.

My mobile phone has about 12 tiny in-built sensors (proximity/gravity/accelerometer/ gyroscope/magnetic field/light/GPS/WiFi/NFC/ finger-print/ touch screen, and more). I could certainly imagine camera engineers coming up with ways to creatively make use of such tiny sensors in a big flippy LCD like the K-1's.

i thought the sensor for ibis only moved on two axes, is it even capable of tilting?

Olympus has five axis ibis. No reason Pentax can't go in that direction.

But all 5-axis stabilization still moves the sensor in 2-axis + rotation of the sensor.
That is enough for compensating for 5-axis of camera motion.

This talk of ibis and feeding indicates the real rationale behind the design - it doubles as a bird feeding table!

I have actually had the same thought, that they could use the position of the screen as input for sensor position. But I figure that while it might not be that hard to implement, it is still not worth it.

i still highly doubt that the sensor will ever move towards or away from the focal plane. i believe fogel is right and that "5 axis ibis" means it can correct for 5 axes of camera motion, not that the sensor moves on 5 axes

can anyone actually verify this?

There's no need to verify, you are correct. IIRC the 2 "extra" axes means compensation for translation movement (horizontally and vertically), besides for angular (h+v) and rotational movement.
But the sensor is moving inside its plane, and the alignment must be very precise - or else.

A very neat idea - certainly gets you thinking - I'm wondering if, just taking it at face value, it wouldn't be useful in insect etc macro, where you sometimes need to put the camera places your head can't easily follow -but I've never used live view for macro,so I don't know how it would work in practise
