Here's one for you:
Currently filters sit on the end of a lens, and are subject to either filter holders or screw-in thread sizes - making it a nightmare if you change lenses or want to use multiple filters stacked, and is expensive, considering the size the glass needs to be. It also adds more layers that you need to keep dust-free.
So consider an area that sits between the sensor and the rear-element of the lens, with slots allowing for filters (much smaller in size) to be inserted into. You get a camera with interchangeable filters that don't care what lens is on the front.
Sure there's problems, such as:
- Keeping dust out of this internal area
- Vertical movement for ND grads
- Circular movement for CPLs
But these can be easily overcome.
I'd patent it if I thought any manufacturer would care!
