The cool looking LockCircle is an aluminum body cap for DSLRs, designed to replace the cheap – and not too snug-fitting – plastic cap that your DSLR comes with to keep dust out of the sensor are of your DSLR when it has no lens. The plastic body caps aren’t that great as many camera users can attest.
The catch with the awesome looking LockCircle is that the thing costs $100 (USD), which seems like a lot for what it does. There were a lot of people out there wondering why the thing is so expensive when it was announced. Now with this video footage of one being made, it’s a lot clearer now why it costs so much. The LockCircle starts off as a round billet aluminum disc strapped to a CNC lathe machine, eventually taking the form shown in the photo above.
It is so cool to see the billet disc start to spin and then the router bits come in and shave metal off to create the product. You really have to watch the video to see how the thing is made. My favorite part is seeing the laser etching machine burn the name onto the product at the end.
