Why Remove the OLPF from the 5D Mk III??

Hi,

I would never ever dream of doing this but....

Can someone tell me if this makes any sense?? If you would get sharper pics and better video then why does Canon add this to the camera in the first place?

Sorry for my naievity (sp?)

The anti alias required is relative to subject, lighting, and tastes.
In MFDSLR we do it in software and Canon DSLR does it in hardware.
Removal will give sharper images but may give excess stairstep on edges.
Also video typically requires strong AA.
The best answer is to do it in software and only where it is required
and to the degree necessary like local dodge or burn.
The Nikon 800E has reduced AA.

There is a recent comparison of the D800 and D800E which reveals a lot about the effects of AA filters. Posts 76 and 78 are a good illustration of the issue. Perhaps counterintutive to many is the observation that the "limiting resolution" is not altered much but the aliasing is reduced substantially. Color patterns can be removed by software but luminance patterns from aliasing are much harder to clean up, although not very common in the absence of fine repeating elements in the image. Others in that discussion show that the AA filtered images can be sharpened more aggressively in PP than the unfiltered ones before artifacts become obtrusive, thus negating much of then perceived benefit of filter removal. You decide on your compromise for your needs, just like all other aspects of photography
