My Reply : I disagree with regards to full frame. As long as the corner
performance of the FF lenses
matches 2/3 of the performance of the APSC lenses the overall system
performance of FF will
be equal to or greater than the Aps performance. Generally speaking,
you dont need as high a
performance FF lenses for better overall system performance than apsc.
Its a larger format, it has
more overall lines of resolution even if the absolute line pairs/mm is
lower.
Regard no AA filter, aliasing occurs when the incoming spatial
frequencies are too fast
for the sampling. With a high resolution sensor and cheaper lower
resolution lenses,
NO aliasing will likely occur. Aliasing is more likely to occur with
super high spec ultra
high resolution * or APO lenses, not average or poor ones.

Cameras with no AA filter are going to separate the "men from the

lenses almost mandatory. Either that or you are going to have to
"enjoy" a lot more time in post-processing. This problem is
exacerbated by a full frame sensor which uses the corners of the image
circle that are getting cropped out by an APS-C camera. In short,
those who want a full frame DSLR are either going to have to use their
best lenses with it, or procure some.
My reply:
I keep telling that to all those funky boys begging Pentax for a full
frame camera and counting on good lenses of the past they already own
and treasure. Once FF will be available, you'll have to buy a whole
new lens outfit based on new-generation lenses (provided they will be
made available) or be satisfied with so-so performance.
That's well known by Canon and Nikon shooters, and mostly neglected
among dreaming Pentaxians. In brief, putting together a Pentax FF
outfit won't cost you less than switching to Canon or Nikon, the
advantage being you won't have to do that all at once.
