JJC WB-77

This JJC White Balance Lens Cap fulfils two functions.
On the one hand it allows you to set a quick and uncomplicated custom white balance on your camera wherever and whenever you like. Especially in difficult lighting conditions the custom white balance is much more reliable than the automatic white balance and the camera can be matched exactly to the color temperature of the ambient light, so that will you will achieve a natural color reproduction without distorting color casts. This saves much time in post production.

In its second use the cap serves as a protective cap and protects the front lens against dirt, moisture and impact.
