Looks like a lens… right up until you pour coffee all over it.
I’m a sucker for a cute gadget, but I’ve also got something of a Machiavellian streak in me, So when I spotted this replica Canon USM Lens Coffee Cup at purveyors of generally cheap-and-awful Chinest plasticware DealExtreme, it occurred to me that, rather than the perfect gift for the DSLR loving person in your life, it could also be used for more devious purposes… such as seeing what colour they turn when you “spill” coffee all over a high-priced lens.
There’s even, rather alarmingly, a companion Thermos lens available as well.
