On the other hand, if the infrared cut-off mirror in front of CCD is removed, it will have a certain impact on normal visible light photography! Because the general CCD can sense infrared light, but the wavelength of infrared light is different from that of visible light, which leads to the inconsistency of their focusing points. In order to ensure the imaging quality, an infrared cutoff mirror is usually installed in front of the CCD!
In addition, as far as I know, a few models, such as Sony F707, F7 17, have made the infrared cut-off mirror in front of the CCD movable in order to improve their focusing ability in the dark, so that they can use infrared to assist focusing in poor light, so these models can directly take infrared photography as long as they are directly equipped with infrared filters. It is said that these models were sold out of stock at that time because of this function.
One more thing, the infrared filter is available on Taobao, but the price is relatively expensive, hehe ~ ~
