  • Four strength options let you control streak intensity
  • Rotating design allows precise alignment of streak direction

Filter Type and Thread

The B+W 77mm True-Streak Blue 2mm Rotate Filter adds a distinctive anamorphic-style streak effect to highlights for creative photographers and cinematographers using lenses with a 77mm front thread. It is built from water-white optical glass to maintain clarity while introducing the effect.

Streak Strength

This unit is the 2mm strength variant, sitting between the strongest 1mm and the more subtle 3mm and 4mm options, so the intensity of the coloured streaks is fixed at this moderate level. Buyers who need a stronger or more delicate streak must choose a different strength filter.

Sustained Use Behaviour

The rotating mount allows the streak direction to be aligned precisely during composition and locked in place for consistent results across extended shooting sessions. The optical glass resists flare and colour shift over time, so the effect remains repeatable from the first frame to the last.

Questions about this item

What does the 2mm strength mean when I put this filter on a 77mm lens?

The 2mm rating is the second-strongest streak setting in the range, producing prominent blue anamorphic-style streaks from bright highlights while keeping the effect controllable.

How does the rotating mount affect the streak direction?

The filter rotates freely in its 77mm ring so you can align the streaks horizontally, vertically or at any angle to match the composition.

Will the 77mm thread fit my lens and what clearance does the frame need?

It screws onto any 77mm front thread; the slim brass mount adds minimal depth so it clears most lens caps and hoods.
