Sun blocker 67mm

Simple tool to mask the sun when it's visible in the photo. Masking it avoids the sunflares so it's possible to compose two shots (one masked and one unmasked) and get a perfect sun photo without unwanted flares.
Easier than placing a finger in front of the camera.

This tool can be screwed to the lens just like any other photographic filter, but it's only available for 67mm lenses.

Along with the complete model there are arms with discs of different diameters. Larger discs are to be used with longer lenses. You can of course modify one of these arms to get larger or smaller discs for your specific needs.
