I would recommend using virtually any other lens instead for
macro work (why use such a big/heavy/awkward lens, especially
if you use a tripod or flash for macro exposures...?). If you
must do it, tubes will not work well with this lens zoomed to
200mm (it isn't even especially sharp at 200mm at minimum
focus *without* tubes..., though it is a wonder lens otherwise
in the sharpness department). I would try a 77 -> 62mm step-down
ring and a Nikon 6T achromat on it (though it may vignette...),
or a 77 -> 72mm ring and the Canon achromat. Use small stops.
Better yet, don't use this lens for macro - buy a cheap used
Nikkor compact-version 200mm f4 and use tubes/converters/achromats
(even altogether) on it - that works well and it can be very
sharp at f11 or so.
Hope This Helps
