1Dx, rumoured D800 and the diffraction question
Oct 19, 2011

Hi all,

just wondering where the limits of the „returns on investments“ are when a camera has more pixels. Beside noise there has diffraction to be considered.

At the-digital-picture.com you find a table where the Diffraction Limited Aperture (DLA, see last column) is calculated for several Canon cameras:

http://www.the-digital-picture.com/Reviews/Canon-EOS-5D-Mark-II-DSLR-Digital-Camera-Review.aspx

I understand that “higher resolution sensors generally continue to deliver more detail well beyond the DLA than lower resolution sensors”, but nevertheless I would like to know where diffraction kicks in with the

Canon 1Dx (FF, 18 MP), Sony A77 (APS-C, 24 MP) and the rumoured Nikon D800 (FF, 36 MP).

Thanks in advance for your replies.

Best, Buellom
