Yep ..a large number of Sonys do have infra red facility..in the form of the usual IR filter that exists in other cameras..but on some of the Sonys it can be moved out of the lens to image chip line..
Some cameras that don't advertise IR imagery nevertheless do have IR capability ( because their filters are not as strong or do not exist ) ..but they would require longer exposure times and a tripod to avid shake during those times ..
One way to check if you have a camera that can "see" IR..( do this inside, and in the dark or dim light ) point a TV remote* at it , head on to the lens from about arms length, press and hold any button on the remote, and take a picture..if the image has a bright spot when you view it..the camera can see IR..
You can also try a long exposure on a tripod ( say 30 seconds or so ) of an electric clothes iron set on "high" again taken in the dark or dim light..if the camera can "see" IR..you'll know it by the "glow" on the image..
Leosghost? I'm mostly a 'metal guy' for my full-time job. Long story, but think lasers and thick metal.
:) I know some of your "confrères" ( colleagues)..my real "calling" for the last 4 decades, is making imagery and sculptures, sometimes it requires the big machines to bend, shape and / or cut the metal we use, before we sculptors work on it..oxy cutters and welders I can use, oxy cutters welders, and electric welders I have,( Bottles and "Stick" and TIG MIG MAG) ..lasers that cut thick metal are out of the range of most sculptors..they require lots of money, and lots of space around them to manipulate the metal..
Wood and stone, we let nature do the rough work, but as well as my hand chisels and gouges for stone and wood, I also have a stable of chainsaws and air powered tools for working ideas and forms out from where I can see them lurking ..
Then there are clays and plasters, and cements and "composites"....
Playing with all of the above is much more fun than writing code and laying out pages..but, I left my huge ( had around 3000 sq feet and a 20' ceiling ) atelier behind when we moved from the south of France..so for now, computers and flat screens take less space..
