Originally posted by monochrome The technological challenge will always be IBIS, and for video the noise the IBIS platform makes.
And there's potentially the problem of the image circle not being quite big enough to allow IBIS on the entire image. In that case the processor might capture a slightly smaller than FF image, leaving photosites around the borders for IBIS.
I wonder how that idea would sell?*
* Noting rumors that the rumored FF lenses are ILIS lenses.
(Is that a meta-rumor?)
For the image circle, the problem isn't really dependant of the body
and it never hapen on third party lenses made for APSC today so I don't see any reason for that to kick in for normal FF lenses.
For IBIS needed more space, it just need to make the same movement as for APSC but for a larger area. It may need 1mm-2mm more in some directions at worst. That not that big of a difference I would say and would not make the body that much bigger.
I would really appreciate they keep IBIS, even if they decide to have optical stab for some lenses; They could combine the 2 for even better performance, but much more it make most non stab lenses far better in dififcult conditon.
It would be a shame that an APSC sensor achieve better low light shoot because of IBIS and so reduced speed + lower isos !
