NiSi 150x170mm Nano IR ハードグラデーションNDフィルター GND8 (0.9) 3段

The hard transition line is perfectly crisp across the frame, so balancing a bright sky against a darker foreground takes seconds instead of fiddly bracketing. Even with the 3-stop density, colors stay true and there's zero color cast to fix in post.

I've been shooting seascapes with this 3-stop hard grad for a month, and the way it cuts off at the horizon line is impressively precise. The 150x170mm size covers my widest lens without any vignetting.

Switching from a Cokin holder to this system was a game-changer—the 150mm width eliminated my wide-angle vignetting instantly. The hard grad cuts right at the horizon line with zero color cast, exactly what I needed for sunrise seascapes.
