Adding SR to a FF camera would have less "displacement overhead" than on aps camera because the magnitude of camera movement is the same, possilby even less with slighty larger and more massive body. In other words, add SR to a FF increases the body size the same absolute amount approx. which is smaller in proportion to the sensor than with APS. jco

That's a lot more than a couple pixels. More like 300 pixels on the 6MP sensors (25.5mm wide sensor is 3008 pixels across). -Adam Bob Sullivan wrote: > Tom, > Similar to my thinking in another thread.
