Originally posted by HSV Interesting implementation, sounds very promising!
Just curious...is the reduced flange distance a requirement for this to work? What are the effects on depth of field (asumming an equal framing)?
What would be the benefits of a real FF vs a "boosted" APS-C?
I think that signal to noise ratio would be one benefit of the FF (because of larger photosites).
Since this thing has AF (for EF lenses) and it doubles the light, in theory this should improve AF accuracy.
Yes. You would need a mirrorless body for "most" of these adapters to work or the lenses wont focus properly.
We will have to see how this effects the gap between the two sensor sizes. I have said for a long time that APS-C can match FF performance if you have faster sharper glass (sharper at larger apertures), but this makes APS-C lenses more expensive than FF lenses. This adapter wont be cheap, but it can be used on multiple lenses.
The photosites on the 36MP D800 are the same size as the photosites on the 16MP K-5. You have to enlarge the K-5 image 2x as much to match the output of the D800 so even if noise is equal the K-5 will look noisier (especially on a back illuminated monitor) than the D800.
