Is 1/4 the look you want?
XT Field Note / XT888 Bottom 1/4
For everyday street and portraits.
Bottom 1/4 is tuned for standard and wide focal lengths under roughly 135mm.
Want heavier night bloom?
Leo’s guide separates everyday Bottom 1/4 from stronger mist options. Choose for the light you shoot.
“Buy the strength for the light you actually shoot.”

Questions about your lens? info@xtfilters.com
Should I leave Black Mist on all the time?
Not for every scene. Leo recommends removing it when fog already softens the image or when fine detail is the priority. Pick the strength for your light.

In-stock orders typically dispatch from China in 1–3 business days. Import fees may apply. Standard returns require unused, uninstalled filters and approval; change-of-mind return shipping is paid by the customer.
