Almost every digital camera is suitable for digital infrared photography. During the infrared conversion, the manufacturer's blocking filter is removed and replaced with an infrared filter. This makes the digital camera sensitive to infrared radiation and you can shoot handheld with fast shutter speeds. The camera can be used as usual, only now it produces special images.
This sounds quite simple, but requires a lot of know-how and the right technology. Since 2011, I have been converting digital cameras from all well-known manufacturers for infrared photography, whether micro-four-thirds or medium format.
