Do you know what the LockCircle is? It is a metal body cap for your camera EF mount which replaces the cheap plastic one provided by Canon. Useless accessory? Maybe, maybe not but one thing for sure: it is expensive at about 100$.
As some of you know, I have trie in the past to have some specific HDSLR parts manufactured so I was very curious when I received an email from LockCircle about their machining process. Take a look, it is pretty cool and it gives a good idea why these cant be sold for 10$ as some people requested. Are they a bit over engineered? Probably. But I am pretty sure there wont be any knock off of these made in China!
