Nikon has filed a new patent in Japan for an electrically controlled Optical Low Pass Filter, which you would be able to turn on or off via camera menus or buttons. In case you are unaware, an Optical Low Pass Filter, or OLPF, is also known as an anti-aliasing filter. Basically, these try to prevent things like moire from getting into your images or video. The downside to having these filters is that they can impact the sharpness of your images.
Currently, DSLRs either have an OLPF or they do not, most do. The Nikon D800E and Nikon D7100 are examples of newer generation Nikon DSLRs which do not have an OLPF. That is why Nikon filing patents for an OLPF with an on/off switch is such great news. You could turn on the filter when needed, but then turn it off when you don’t. This would solve the problem of having to choose between a camera body with or without the filter and then being stuck with it.
Nikon filing a patent does not mean that anything like this will ever be implemented into their camera bodies, but the idea of it is still very cool to think about. Don’t you agree?
What are your thoughts on this? Would this be a feature that you would like in your DSLR? Let us know in a comment below.
