The TS-E lenses will be key for those wanting maximum resolution and extended DOF. The diffraction limited aperture (DLA) is projected to be f/6.7, so f/16 or even f/11 won't be as usable at 50.6 as it is on the 5DII et al. Shooting with a T/S lens at f/5.6 or f/8 with tilt will be the way to give your image more DOF with a single exposure while keeping the aperture set for maximum sharpness.ajfotofilmagem said:There are several old Canon lenses able to show much more detail with a 50 megapixel camera. A brief list:Phil Lowe said:Just curious about something...Is there any older Canon lens - like the EF100-400L - that will be able to resolve anything close to what a 50.6mp sensor can resolve, or will buying a 50.6mp camera require all new glass?

I know some may chime in to explain all the technical details and limits here, but in practice, this is going to be the case. Hopefully this will push Canon to upgrade the non-L TS-E lenses (esp. the 45mm).
EDIT: Here's a good example from The-Digital-Picture:
300 f/2.8 IS II on the 1DsIII vs 7DII @ f/16
While not the most ideal example, the effect of diffraction on one of the sharpest lenses Canon makes is shocking on the 7DII (roughly same pixel pitch as 5Ds), even at f/11.
