I have sausage fingers and often shoot in cold and wind. I have a 77mm circular polariser and rings that I leave on my lenses that step them up to 77mm. I find screwing and unscrewing the polariser an absolute nightmare. Sometimes it sticks. Sometimes my sausage fingers are frozen stiff. Sometimes the adapter ring comes with it etc.
I've been looking at filter systems, and the Lee system looks nice, but really I have no interest in nds, nd grads or any other rectangular filters, and the cost is not insignificant when I factor in the holder, the piece to mount the polariser and adapters for my lenses. Plus I lose the use of my lens hoods that have saved my lenses on countless occasions, with the alternative to pay another whack for a compatible Lee lens hood. This seems like a long way round to make swapping polarisers quick.
There has to be a better way. Is there a simple way of quickly swapping a circular polariser between lenses (of different filter diameters)?
There is a solution that involves using magnetic adapters, but this only works with sharing filters between lenses of the same diameter. And I'm not sure how sensible it is putting powerful magnets next to a lens's circuitry or how safe they are.
