It was only a matter of time before this happened, especially after we saw the Canon thermos zoom lens a few months back, and now to continue the rivalry, a Nikon version has appeared. This Nikon AF-S 24-70mm f/2.8 coffee cup is currently going for $50 on eBay. So when do you think we’ll start to see more of these thermos lenses from other manufacturers such as Sony or Pentax?
