The Tiffen 86mm Coarse Thread 81EF Light Balancing Filter helps to decrease the color temperature by 650K in order to warm the image slightly in order to match the color quality of illumination. When using an 81EF filter, you will be able to attain 3200K balance when the prevailing light source is 3850K. The warming effect of this filter requires a 0.6-stop increase in exposure for normal results.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

Q: 4. Will this work on a Hasselblad 500 /501 series camera?

A: Many V-system lenses for the Hasselblad 500/501 do not use the same filter mounting type and instead use bayonet or drop-in filters, which means the Godox Ring48 macro ringlight is not natively compatible with them. However, depending on the lens, you may purchase adapters separately to use in conjunction with the adapter rings provided by the ring light.
