Re: *ist D sensor and 35mm lens resolution

[John Forbes]

I would agree that, in practice, the necessity to blow up a *ist D image 
may not matter if you are using a lens with very high resolution.  
However, not all lenses, especially zooms, exhibit superb resolution, and 
in such cases I am sure that the difference will be observable.

The only way to resolve this will be to conduct some comparative tests.

I agree that film resolution also comes into play, but you cannot ignore
the limits of lens resolution, as your argument suggests.  If so, why
would we talk about "sharpness" or have lens resolution tests.
Having executed resolution tests using most of my lenses I can say that 
most
Pentax primes deliver sufficient resolution to out perform the *ist D, 
that
said most of my lenses are high performance primes.

I think, with respect, that you are missing something.
I think not :-)
