Je ne pensais pas que Nikon avait fait aussi fort pour le moiré comparé au Canon.

A voir en grand. Les lettres sont plus lisibles sur le Nikon.

Pas de moiré sur la petite tour (volets en blancs).
"This cross
section gives an example of the Moiré pattern produced by the Canon 5D
Mark III. Notice the white horizontal slats on the top part of the dome.
I can only assume that the AA filter on this camera is weaker compared
to Nikon's."

Là aussi le Nikon est meilleur.
"Obviously, the
Nikon D800 is in a totally different league. Absent of color noise or
any pattern, this image reveals Nikon's exceptional performance."
Encore une pour se mieux voir la gestion du bruit

"I know this
is disappointing for Canon shooters but on the bright side, I figured
out a workaround if you shoot RAW. Start by overexposing by about 1 stop
above the correct exposure before taking your shot and then underexpose
by the same amount later in software, basically normalizing the image.
For example, in Lightroom, you would move the exposure slider to -1.
This gives you the correct exposure but the shadow detail is much
cleaner just in case you need to push it a stop or two. In other words,
using this technique banding and noise subsides considerably. I have
been using this workaround for many years and have been happy with the
results.
In
regards to the Nikon D800 handing of noise in the shadow areas, I have
to say it's nothing short of amazing! Kudos to Sony and Nikon for the
new sensor partnership. The Exmor sensor is exceptional and there is so
much detail in the shadows. I can push the shadows more than 4 stops
without any hint of color noise. WOW! Let's just say the D800 sensor is a
breakthrough in sensor technology."
"In order to get
the most out of Nikon's 36MP sensor, we need to use the best glass at
their sweet spot apertures. Apertures too wide will lessen resolution
due to lens aberration and too small will rob resolution due to
diffraction. "
