Canon started this at the Olympics and had the first round but now Nikon are ready to retaliate. The thermos shaped like a 24-70mm f/2.8 Nikkor AF-S camera lens is already up for pre-order on eBay so you might start saving.
Surely if you have a real 24-70 f/2.8 in your camera bag this is hardly exiting news but most amateurs will probably never get a chance to play with one. The only problem is that at 50 US dollars asking price this thermos is as overpriced as the actual camera lens it mimics, except that it didn’t take years of development.
Now how about a Nikkor 14-24 f/2.8 beer mug?
