There's no such thing as a sharp or soft DSLR.
Really? Then why is Nikon selling both a D800 and a D800E? Isn't one of those sharper than the other? By extension, doesn't it stand to reason that the properties of the anti-aliasing filter determine the 'sharpness' of the dSLR, and that's one of the design decisions that a manufacturer makes?
Canon has stated that the 5DIII offers improved video characteristics, in particular they mention a reduction in moiré. I'd argue that the easiest way to reduce video moiré is to use a 'stronger' AA filter. One of the trade-offs in doing so is reduced sharpness.
Worth noting is the person who took apart his 5DIII and removed the AA filter, in particular the statement, "It does seem like a particularly strong optical low pass filter on this camera... OLPF, AA, anti-aliasing filter, call it what you will – it seems Canon put too strong a one in the 5D Mark III! Yes it crushes moire but the trade off is less resolution not just in video mode, but also for stills." You can see examples on the linked page.
funny you mention that!
I was painstakingly analysing my $50 note shots of 5D3 vs 5D2 again at 200% and you can distinctly see moire pop up in the 5D2 shots (which also happen to appear to be sharper than the 5D3 to me at this magnification)
the 5D3 shot dont seem to have the moire issue.
Although all this is observed at 200% magnification it really has a miniscule impact on the overall image.
Disclaimer : I dont go through puiles of pictures at 200% for fun, just trying to get to the bottom of my twightlight zone AF issues i'm having
