I use a 600mm Sigma mirror lens for photographing birds. It satisfies my
requirements and cost about $300 from KEH with filters, caps, and a case.
I'd try another mirror lens without hesitation, save for the cost. Doubtless
a refractor (no-mirror) design can be sharper, but that way is usually more
costly, or at least bigger and heavier.
