Promaster 5687 72mm 可変NDフィルター - HGX Prime（1.3〜8ストップ）

Finally a variable ND that doesn't introduce color cast across the full 1.3 to 8 stop range. The hard stop at the ends of the adjustment ring makes setting it to maximum darkness foolproof.

I was a bit skeptical about the 1.3 to 8-stop range, but it gives me just the right control for both bright midday sun and softer late afternoon shots without any unwanted color cast.

Finally a variable ND that doesn't give me a nasty color cast at the darker end of the range, the glass is noticeably sharper than my old budget one.
