Kenko-Tokina's variable NDX ND filter launched

Kenko-Tokina has launched the NDX ND filter, offering ranges from ND2.5 to ND1000.

The NDX follows the same principle as a standard ND filter, but offers variable strength by essentially stacking two filters together.

The Kenko-Tokina NDX filter was announced in September last year and will be stocked in Japan from August 26.

According to Kenko-Tokina, using the NDX range won't affect colour balance, glare, or reflections in photos.

The 77S fits a 72mm filter thread, and is priced at ¥55,000 (around £435), while the NDX 82S, for an 82mm filter thread will cost ¥65,000 (around £515).

Earlier this year, Kenko-Tokina bought rival filter manufacturer Cokin.
