I was wondering if anyone here had experience with faster mirror
lenses. I saw a lens that tickled my fancy and budget, a 300mm
f4.5, and I've been thinking about picking it up.

I'd be primarily using it for baseball, for which I've been
stealing Dave Brooks' Sigma 300mm f4. Speed-wise I've been
shooting f5.6-ish anyways, so the fixed aperture is not an issue.
Part of my interest is the size/weight factor; another part is the
desire to differentiate my work. Aside from the donuts, what are
the usual characteristics of a mirror lens?
I probably shouldn't buy it. If I buy it and hate it, are there
any Toronto PDMLers who'd want to buy a slightly used 300mm f4.5
for 90% of the price listed at that link?
Alternately, is anyone out there looking to sell some longer,
faster glass?
300mm is a bit short for a cat lens. I have the 500/5.6 MC Rubinar
Macro and the 1000/8 Rubinar Macro. Both are very good, but the 500
is significantly better.
These are not good lenses for sports since they are rather slow to
focus and the depth of field is very shallow. They're best for
static or slowly moving subjects.
