I have this great digital Sony NEX camera that was converted to shoot infrared photos. Sometimes I wonder if I could revert it to taking "normal" pictures with the use of a filter. I just started digital infrared and when I shoot infrared on film I know i have to use different film.
EDIT #1: It's a NEX-3 (not 3N).
EDIT #2: The modification that was done is such:
This camera was converted to Full Spectrum by removal of the low-pass/anti-alias filter. There is still a protective glass layer in front of the sensor, and the sensor may be cleaned using the normal means (bulb blower, brush or wet clean). As such, the camera is only for infrared use - put the infrared filter of your choice on a lens and fire away - you can hand-hold the camera, since exposure times are in the normal range due to the Full Spectrum conversion, and focus using live-view on the LCD screen as necessary. Internal shims were removed to compensate for the low pass filter removal, so the camera focuses perfectly both with Sony autofocus lenses, and manual focus legacy lenses used with adapters (I've used Canon FD, Zeiss Contax, and other lenses with great success on NEX bodies). White balance has been set to achieve maximum infrared effect.
EDIT #3: Following @Olivier's great answer, I got a UV/IR filter and produced these, which are satisfying and an interesting direction to explore - the white balance changes a lot of things:
