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. 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.
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.
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?
Seems like a case of "damned if you don't but damned if you do" to
me. ;-)
