This gallery shows a DIY conversion of a Dynax 7D to a dedicated IR camera. If you try to do this yourself, you do so AT YOUR OWN RISK. It may be dangerous for your own and your camera's health. There are high voltages in the flash circuitry, which can be lethal. Please only try this if you know what you're doing.

The original 4 mm thick IR hot mirror was replaced by two pieces of 2 mm thick glass cut from the glass of a photo frame. In between the two sheets of glass I put a fully exposed film strip, which serves as the IR pass filter. The viewfinder still shows the normal visible light image for framing and autofocus seems to work well enough.

There are also some quickly done sample shots with various lenses.
