If you've been following this blog, then you may already know that I collect lens replica mugs. There are some cheap versions, but the best ones have the stainless steel insert and are 1:1 scale to the real lens, even down to the AF and IS switches.
Recently a new one has shown up in the form of a Canon EF 24-105mm F/4 IS Tea Cup. These are very small (shot glass like) tea cups with the Canon Lens inspiration. Sure, it's a novelty and great fun for collectors, but keep in mind these always make perfect gifts this time of year that won't ever get thrown away. These Lens Replica mugs come in Canon and Nikon in all the popular lens sizes. Some replicas are exactly to scale, and the new smaller cups are also available via eBay (click here).
