After flashing a Philips SPC880 webcam with the SPC900 firmware I wanted to see what it was capable of. I made up an adaptor fitted to a Canon rear dust cap so I could use the SPC880 webcam on the back of Canon EF mount lens using a simple 1.25″ nose piece adaptor on the webcam.
This is a quick test of the video the Philips SPC880 webcam and Canon 600mm f4L prime lens can achieve.
Below are a couple of images of the Canon EF adaptor I’ve made to mount the webcam onto the rear of the Canon 600mm f4L IS USM lens. The main body is a simple lightweight aluminium tube which I need to get anodised. I’ve bonded a standard Canon EF mount dust cap into the front of the aluminium mount to interface to the lens. The nose piece adaptor to couple to the webcam was supplied by First Light Optics
