I would bet that to the naked eye, there is no difference is
resolution between a photo taken at 20mm with the DA* 16-50/2.8 and
one taken with a full frame sensor at 31mm with the FA limited. I know
from direct experience that the 16-50 is at least the equal of the FA
35/2, and in fact it appears to be noticeably sharper at f2.8 and f4.
So wonderfully wider images are ours to enjoy. A number of Pentax
photographers have said the DA 12-24/4 is at least the equal of the A
15/3.5, and it's only a bit longer. I believe a third-party
manufacturer makes a rectilinear zoom for Pentax that is 10mm at the
wide end as well. Full frame isn't necessary to achieve wide angle
images.

Paul,
For me it means that all the old, sharp wide angle glass I own will
deliver the FOV I thought it would when I first bought it. I
understand the fact that the fov is indeed wider on 24 x 36 film. For
me, the fact translates into wonderfully wider images.

Larry,
Put the FA31mm limited on a film camera body and shoot a roll of
film.
It will change how you feel about the 1.5x crop of today's sensors.

Yes, it will reaffirm that the fov of any lens is indeed wider on
24 x 36
film than it is on a sensor of smaller dimensions. Other than
that...not
much.

The 645D? What a camera... Lovely viewfinder too.
Thanks for posting this.
Pentax needs to sell cameras now. If Ned says that the price on
the K-5
is going to drop $200 in a month, no one will buy one this month.
When I started buying lenses for my K100 a couple years back, I
didn't
buy any lenses that wouldn't work with a 24x36 sensor because I
was worried
that a "full frame" camera would render them obsolete. Now, I buy
the
equipment that solves today's problem.
The needle tracks up and down both of my arms spell out "fast
primes",
but my K-x will do better in low light with f/2.8 glass than my
K100 did
with f/1.8 glass, the K-5 better still. Pentax will get more low
light
benefit for their development dollar from Moore's law than they
ever can
hope to with fast primes. My guess is that they'll put their
efforts into
sharp zooms, possibly small, sharp zooms.
The next generation of photographers may be buying cameras never
having
used a camera that hasn't had a zoom lens. It's what they'll
expect, and
what they'll look for when shopping.
