Canon 135mm f2.5 Telephoto / Portrait lens, breech with built in retractable hood and front and rear caps. Immaculate glass, cosmetically near perfect, a very sharp lens that I used more than my 50mm 1.4 -- but I no longer have an FD mount Canon camera to put it on.
$30 + $11 USPS Priority Flat Rate shipping to anywhere in the US = $41 total.
I've reposted this because someone pointed out that I'd listed it as a slower lens -- it is in fact the 2.5, not the f3.5.
