As has been discussed many times already here, once the sensor
resolution exceeds that of the lens (in broad terms), there is less need
for a strong anti-alias filter.

I wonder whether this D7100 has the same system as the D800E, retaining
a two layer low-pass filter, one layer "cancelling-out" the effect of
the other (sorry for weird explanation, but IIRC that's more-or-less how
Nikon described it), or if it's got none at all?
As described by Nikon, the D800E apparently needed that system to
maintain the same optical path as the D800. There's no "ordinary" D7100
with AA filter.
Some discussion and argument in the DPReview forums as to whether the
D7100 means there will be no "D400". A couple of things suggest that
there is room for a D400 - the D7100 frame rate is not faster than the
6YO D300, the buffer is smaller (only 6 raw frames), and the "kit"
includes the relatively low-end 18-105 zoom.
OTOH, Nikon's usual trick was to release the expensive model first, then
release a version with a few features removed and a lower price six
months down the track. (ie D200 then D80, D300 then D90).

Anyway, the D7100 looks very interesting. The 51 point AF system on DX
as per the D300 gives excellent frame-coverage - not all bunched-up like
on FX models. The price is good IMO ($1200 for body). 24mp on Dx seems
like a lot - it will be interesting to see samples.

None at all, apparently. Nikon's excuse for using the pass filter on
the D800E was to preserve the focal distance so they wouldn't have to
move the sensor. I wonder how they dealt with it this time?

Yeah - I read that reason given by Nikon, which doesn't make sense to me
as the sensor plane itself should be the same.

there are two antialias filters, one for each linear dimension. nikon
removed the second one and replaced it with something to counteract the
first one.

I disagree, with operating income $500 million, recalling and fixing

premium quality products (including the customer support which should go
along with that) eventually could.

And yet doesn't seem to have had much affect. It's like Politicians and

Hopefully not "corporate culture":

IIRC middle managers systematically filed complaints in bin 13.

They used to run ads here - "don't you wish /you/ owned a Mitsubishi".
Ummm - no thank you very much - and I never will.
