So is the 28-70mm f3.5-4.5 Nikkor, certainly at f7.1. RichA's results may
be accounted for by mis-focus, a particular zoom model's poorer performance
at close focus, camera shake, or? There is no reason why a wide angle lens
that is sharp on 35mm would not be sharp on digital (and if anything, sharper
than a middling-quality DX lens). For instance, the Nikkor 18-70mm is a
decent lens on digital, but the 16mm f3.5 Nikkor is noticeably sharper, as is
the 24mm f2.8.

I agree. The 18-70 really isn't a bad lens for being a DX lens and for as
little it costs. That has to be one of the best starter lenses ever offered
by Nikon or any other manufacturer. What ever happened to the day when the
old 50/1.4 AI was considered a starter lens?

It died somewhat after the time that the 50mm f1.4 *pre*-AI
(just the half-moon clip for the Photomic meter) was considered a good
step up from a 50mm f2.0 or so. :-) I've still got a couple of these,
which I can't mount on the D70 -- unless I modify the aperture ring to
give them the AI capability. But since I now have a 50mm f1.4 AF lens,
why bother?
Enjoy,
DoN.

That's a bit before my time but the thing that irks me is they don't
even make an equivalent normal fast prime. It's simply not available,
you have to go to Sigma's 30/1.4

Go look up parallel ray lens design as it applies to digital cameras
and you'll understand why it performed that way.
BTW; Whenever I do these tests, I use manual focus and a focus
magnifier.
