So, you thought Canon had some ridiculously large lenses. The truth is, it ain't got nothing on the former Soviet Union, which came up with this fearsome beast -- a 158kg, 1.3m lens for its spy satellites. Oh yeah, it's also for sale.
Pictures, of course, don't do this bad boy justice. As Michael Zhang over at PetaPixel points out, the 470mm-diameter lens is wide enough that you could "fit two basketballs side by side".
The lens is for sale on SS.ua, a Russian classifieds website for the princely sum of 460,000 Ukrainian hryvnia, or about $24,229 Australian.
According to one Vladislav Kern on USSRPhoto, the lens is from the Amber-4K2 satellite, which is equipped with a Pearl-18 camera system.
I guess it'd look good on your mantelpiece, but it'd be hard convincing guests you're not just compensating for your, uh, 18-55mm.
