Fits 49mm Lens Threads. (Optional free 49mm to 40.5mm step down ring)
Nano coated to reduce reflections.
If you have one of those pesky 40.5mm filter threads (as I do) then I can supply ("free of charge") a 49mm to 40.5mm step down ring which looks right on the lens. Please put a note on the order and also message me immediately before or after placing your order as I do not automatically include this.
These 49mm UV/IR Cut filters (also known as a "Hot Mirror" because it reflects the unwanted infrared "hot" wavelengths away from the lens) are designed to fit on the front of the lens to replace the filter removed from the sensor on Full Spectrum/IR Converted Cameras. It allows the converted camera to be used as a conventional camera by blocking the invisible UV/IR wavelengths which would otherwise cause undesirable effects in regular photography.
With one of these fitted to your lens at all times, you would just have to swap it for your desired IR filter for infrared shots. Some white balancing will probably be necessary the first time you use it, and you can then store this setting on the camera. White balancing for infrared shots should also be done (with an IR filter attached) and stored as another white balance setting but, whilst still important, most cameras have a white balance limit, and can't properly white-balance for infrared with a dark red IR filter on the lens, and you would finish correcting this in post-processing. Some cameras may show an "error" when white balancing for IR, but it has still done it. This just means that the camera cannot go far enough down the colour temperature scale to fully white balance.
If you are looking at these, you possibly already know that!
For a range of 49mm IR filters from 590nm to 760nm, please see my other listings.
