Frequently Asked Questions
What does the 85A color conversion filter do?
The 85A filter corrects the color balance when shooting outdoors with tungsten-balanced (indoor) film, warming the image to produce natural-looking colors instead of a blue cast.
What is the benefit of the multi-coating on this filter?
The multi-coating reduces reflections and lens flare, helping to maintain contrast and image sharpness when the filter is attached.
What lens thread size does this filter fit?
This filter fits lenses with a 55mm front filter thread.
Is this filter useful for digital photography?
While originally designed for film, the 85A filter can be used creatively on digital cameras to add a warm amber tone to images, though digital white balance can achieve similar corrections in-camera.
Does this filter affect exposure?
Yes, like most color conversion filters, the 85A absorbs some light and typically requires an exposure compensation of approximately 2/3 of a stop.
