John,
I generally use closeup filters only on longer lenses for the following
reasons:
- Closeup filters usually work better on longer lenses. Since Nikon's
"T" closeup filters are better corrected for long lenses, I would use them
in preference to their single element No. 0, 1, and 2 filters.
- The advangates of the "T" filters are probably lost when used on
wide/standard lenses, which may be why Nikon recommends the cheaper single
element closeup filters. However, I imagine that the "T" filters are just
as good on wide lenses.
- Closeup filters give greater magnification with longer lenses. On wide
angle lenses a closeup filter will only give a slight increase in
magnification. If you want to get closer with wide angle or standard
lenses, I suggest you consider lenses which can focus close without
filters such as: AIS 55/2.8 micro (1/2 life size), or AF 35/2 or AIS
28/2.8 (both about 1/4 life size).
