IR cut filter for Blackmagic Pocket Cinema Camera 4K (MFT), brand new and unused. This is a replacement part for repairs. I kept it as a spare, but I'm selling it because I won't be using it. Size: 27.5mm diameter, 1.5mm thickness. This is a non-genuine part with an "AR coating" that is less susceptible to UV light. From a layman's perspective, I disassembled the original part and compared it to this one, and the size appeared to be the same. *This is a compatible part that requires disassembly, which is not covered by the manufacturer's warranty. Please purchase only if you are able to repair it at your own risk. As this is a private sale, there is no warranty whatsoever. Please be sure to check the size etc. beforehand. Please purchase only if you understand the nature of the product. Please refrain from purchasing if you want a manufacturer's warranty or if you are unable to research and disassemble it yourself.
