If the Pentax lenses I have now work well on the Pentax *ist DS (and

I gathered, but it is hearsay from memory, that most OM lenses are
simply not sharp enough on the 4/3's sensor. It is both smaller and
higher resolution. It might not be true: that's why I said to test for
yourself :o)
I consider the Olympus OM system lenses to be comparable to same-era
Pentax lenses of like focal lengths, at least with respect to resolution
and contrast, rectilinear correction.
I would be _very_ surprised they weren't.
If it were true that the OM lenses aren't sharp enough for the E system
sensor, it's likely true that the Pentax lenses aren't either.
That was my point.
Interesting conjecture:
The E-330 4/3 format sensor has approximately 174.2 pixels per mm.
There's been a lot of talk here and elsewhere about wanting an uprated D
model with 8-10Mpixel. If you take the same pixel density and put it on
the Sony-dimension chip it comes out to 4094 x 2735 pixels, or 10.6
Mpixel.
Much-maligned Herb Chong has stated several times that most Pentax lenses,
with the exception of the really high-end stuff (Macro's, F*, FA*) would
disappoint on a 10 Mp APS sensor. Time will tell...
By the way, does anyone know how old Nikkors work on the D200?
So if Pentax releases a 10Mpixel version of the *ist D, will the Pentax
lenses be adequate to deliver the kind of performance that its sensor
can achieve?
We started talking about M-era glass. DA's and D-FA's might (will?) be
better...
