I got the Sigma 150-600mm f/5-6.3 DG DN OS Sports Lens awhile back and had wanted to get a chance to use it more this summer. I am instead planning on doing that this fall in Washington & Oregon to get some landscape and wildlife footage. Also some people/city shots.

The only thing I need to plan for at this point is ND. I will be using both an S1H & Sigma FP to acquire the (4k/6k raw with Atomos) footage. 180 shutter/30fps & going to attempt some slo-mo (to the extend these bodies can) as well.

For the landscape (locked off) shots I want maximum sharpness (FP doesn't have AA filter, so figuring it for these ones) and so I would prefer to minimize any hit from the ND.

What ND system/option would you purchase for something like this? I have multiple options with my other lenses, variable ND & fixed (all screw on). Based on subject I might be 5/6.3 or down to F13 at any given time.

I just have one screw-in 95mm 2-stop ND from B+W for my 500mm PF. Since wildlife are taken when the sun is lower I have never needed anything more than a 2-stop filter and a lot of times I don't even use it. I shoot most of my footage at 30fps or 60fps also.

However since you said landscapes you might need a stronger filter if you plan on shooting something with the sun reflecting off clouds.
