You can pick up good 55mm 2.8 and 3.5 AI micro-nikkors cheap second hand
(I just sold a nice one for US$ 50). But not only will you not get
autofocus, but you also won't get metering on a D70. Also, if you do
stuff closer than 1:2, having to muck around with an extension tube is a
pain in the neck - and a good method to help get dust on your sensor -
which you will see very clearly on macro shots taken at very small
apertures. Try 105mm as well as 60mm. If you like 105mm, then look at
Sigma 105mm EX. IMO the Nikkor advantage is mechanical quality. The
Sigma 2 stage focus option improves (but doesn't completely solve) one
difficulty that these lenses present - it takes an eon for the lenses to
focus from 1:1 to infinity and back - and sods law ensures that the lens
will do that at the most critical moment. Most of your sharpness issues
with any of these lenses on a D70 are going to relate to focussing (the
screen isn't brilliant for MF, and as mentioned above, you will find AF
extremely annoying at times), and controlling mirror induced camera shake.
The 105mm is also a useful and quite fast f2.8 medium telephoto, and the
60mm a good portrait lens.
Incidentally, I have had reasonable (much better than I expected)
results with a 13mm tube on the kit 18-70 zoom, at 50mm and above.
