Ah, I think I see what you meant.
Is there a reason you don't want to stack filters?
Have you considered a Variable ND filter? We use them all the time. Phenomenal.
Ya', but I'm trying to future proof and not try to address individual lense needs. I'd pick one of those up for run and gun with as zoom, though.
4x5.65 would be the safer choice rather than 4x4 if shooting wide 24mm yes? I'm about to order a few now for the redrock matte box. I'll be shooting lots of sunrises and beaches. I was thinking horizontal schneider .6 , .9 and a few grads. Any advice before I order?
