The 67mm Multistop Fader Filter from Formatt presents a quality, cost-effective and efficient way to control neutral density effects. This filter is effective when shooting under bright light conditions when you are using high speed ISOs or fast film. By simply rotating the ring on the filter, you can control your exposure up to 8 stops. Neutral density filters appear gray and have no effect on color although Formatt does not recommend using it above 5 stops where some color cast may be present.
This filter is especially valuable to nature and portrait photographers who need control over their depth of field. For the nature shooter, the Multistop Fader will allow you to make longer exposures to create blurs such as when shooting city traffic or waterfalls where you want to capture the motion of the water rather than a dull static shot. Portrait shooters will appreciate this filter since it will give you the freedom to shoot at wider apertures in order to separate your subject from the background - again, when shooting with fast ISOs under bright lighting conditions.
The outer ring of the filter is indexed with reference points that can be used to judge stops. These marking also show minimum and maximum stop loss points. The outer ring is also wider than the rear thread ring and this is deliberate in order to avoid any chance of vignetting (the darkening of the corners of an image).
Formatt filters are manufactured through their proprietary system of Absorbing Cell Technology (A.C.T.) where the CR39 resin is manufactured, color added and then sandwiched between two sheets of high-quality Schott glass. In this way, the color of the filter can be evenly produced, controlled and protected by the glass. This makes it possible to change filters in the middle of a shoot and be assured of color and quality consistency. Edging is perfected through a water jet cutting machine that maintains the highest possible standard for each filter that comes off the assembly line.
The Multistop Fader is made by Formatt, an English company with a 50 year reputation for producing quality filters for film and MPTV.

Comments about Formatt 67mm Multistop Fader Filter:
The filter works great, as you'd expect. Only thing is it needs a clean when it arrives, and the box it comes in is not the best storage for it.
It's thicker than I thought, which is fine, but if you need a really thin one try another.
Great for any form of photography or videography.
