Here’s an interesting look at the guts of the pellicle mirror Sony A55 and how the camera works. The camera being examined in the video is already disassembled and neatly organized by layer. If you haven’t seen or read much about the A33/A55 before, this video will bring you up to speed on the advantages of having a translucent mirror instead of a traditional one.

Ever wonder what actually happens between the time you press the shutter button on a DSLR and when the image shows up on the LCD screen? Canon made these two videos explaining how their DSLR cameras work and how they use CMOS sensors to turn photons into photos. You’ll probably find this pretty interesting if you’ve never learned about CMOS sensors before. For a more in-depth lesson, check out the sensor tutorial over on Cambridge in Colour.
