Schneider CFG Classic ND 1.8（4×5.65″）– フィルター

Cutting my exposure in half for a bright beach scene felt effortless—the glass is crystal clear and the 4×5.65 size slid right into my mattebox without any light leaks. I've shot a few sunsets with it and the color shift is basically nonexistent, which is exactly what you want from a neutral density

This ND 1.8 filter knocked off just under 6 stops exactly as expected, and the glass stays perfectly clean even in dusty outdoor shoots. It’s a solid workhorse for keeping shutter speeds wide open in midday sun.

Finally got a proper 4x5.65 ND filter and the optical clarity is exactly what I hoped for — no noticeable color cast even at full 1.8 density. The glass feels substantial in the mattebox, and the locking ring is tight enough that I don't worry about it shifting mid-shot.
