For my micro four thirds bodies, I have the 3 main pro lenses (with others), they being the 12-40 Pro, 40-150 pro and 7-14 Pro.
Been looking at a filter system for the 7-14 and am a little undecided.
I currently have a Lee Seven5 system with soft and hard ND Grads, Little Stopper and Big stopper which are 85mm wide and work just fine on the 12-40 and 40-150 but not on the 7-14.
I also have (from my full frame days - now departed), a Lee 100mm system comprising Soft & Hard ND grads, big stopper and Landscape polariser. I notice that NISI now make quite a nice 7-14mm holder, based around their V3 and V5 holders (which are 100mm systems). If I purchased this and started using the 100mm filters (both the Lee and NISI ones), I was told for ND grads that the full size 100mm filters have graduations which are based around FF cameras and not the smaller M4/3, hence Lee developing the Seven5 system with tighter graduations, and so the graduated bands appear quite differently on the smaller sensor cameras ?
Has anyone used 100mm ND grads on M4/3 and can comment on their effectiveness please. I would have assumed that a 100mm hard grad would act like a soft grad on M4/3, with no real substitute for it's soft grad ?
