Re: [OM] Extension tubes?

[John A. Lind]

Thanks,
I had pretty well concluded the Vivitar's must be auto tubes as putting any
one of the three between an auto lens and the body does not change the
lens/body behavior at all.  But never having seen or used one, I didn't
know if there was something I was missing.  The several replies confirmed
my suspicions . . . they are indeed "auto."

And now for something completely different . . .

I noted that my tubes have virtually 100 0ght transmission (no spiders)
and it was impossible to get any of them to exhibit flare . . . or
distortion.  Measured them without any lens on front as I didn't want lens
performance to skew tube performance.  Allegedly the glass in them is a
very secret formulation developed by the same guy who once sold clothing to
Kings.
