Jens,
The 24x36 sensors are far more demanding on lenses, because they require
superb edge performance on 35mm lenses, while the subframe sensors can
live happily in the sharp centre of the lens's image. Note who's
complaining the most about poor lens performance, it's not the APS-C
shooters, it's the full-frame shooters who've been let down because
Digital sensors require a light path closer to perpendicular and also
show edge sharpness issues far more than smaller sensors do.
Full Frame 35mm is simply more demanding on lenses, and requires more
expensive and higher quality glass than subframe APS-C for good performance.

Nope, I was just supporting Rob, who obviously wants a larger sensor than
just 15x24mm. It's less than half of a "normal" negative. So do I, BTW. I
want it to be big enough to be adequate for actually "makeable" lenses.
Small enough to give me great DOF.
The small sensors do - as the resoultion is increasing, require more and
more of the lenses ability to resolve. This means HUGE expenses on lenses.
Who wnats that?
That's a fair statement, I believe. I would very much like to have a FF
sensor, but it seems they are not (yet) quite good enough (soft corners?)
Who the h... says that a 15x24mm sensor is the "ultimate answer" to the
sensor size?
Perhaps it's not 24x36mm either. Perhaps it's actaully 20x29mm! Canon seems
to think so. Why not listen to the expeters - they probably sell more DSLR's
than anyone else? Canon is currently setting the DSLR standards - whether
you like it or not.
I don't really want to switch to Canon. The problem is - I may have to, if
Pentax can't deliver a "state of the art" DSLR sometime soon: 5-8 FPS, as
well as correspondingly fast AF and write speed. Pentax seem to be way
behind as far as speed goes.
Come on, Pentax - try to catch up, will you, pleasw? Before the very last
"pentaxians" are leaving too - except of course, for a handful of true
"believers" from the Spotmatic and LX generation! LX was twenty years ago,
right! Tell me to shoot action using maunal focus! Heck - I can do that with
one of my Exakta VX1000 - from the sixties! Or a K1000!

Jens

Nop, but appr. 5mm more in each direction!
That ought to count for something - 60% more, actually.
It doesn't count as full frame, which I believe is what you were implying in
a previous post.
I could be wrong about your intent though.
