: Unless I'm really missing a n important concept, a tube simply has to
: be level and light tight.
:
: Given that (and feel free to disagree - I'm a macro newbie)
Two pitfalls here:
- Some 3rd party tubes have a fourth OM-3/4 spot reset unfriendly screw in
their mount.
- The Oly tubes have different lengths than any 3rd party allowing continous
magnifications with standard lenses up to 1:1; the 25mm directly gives 1:1
with the 50mm macro.
: can anyone recommend a source for an inexpensive set
: of auto extension tubes?
I have a set of Kenko tubes that have three screws.
