Some of our clients have reported that at times they have encountered flare (most often represented as a hot spot in the middle of the frame) while shooting with the Rodenstock 23mm HR Lens. Capture Integration has been able to duplicate this issue. Our findings conclude that this can result from light paths arriving from various directions. Light leak and internal reflectivity have been eliminated as sources for the effect through various steps of eliminating directional and ambient light.
In an incredible display of good timing, we tried utilizing the new Cambo Lens Shade to see if we could improve the situation. Indeed we found that we were able to. We found that the unique ability to asymmetrically compress and expand the lens shade is an essential factor in reducing the flare from the 23mm HR. Some samples are below - before and after versions of the fils as shot and dramatically enhanced to easily see the effect and then a crop of the before and after. There is also a capture of the angle of the lens shade that was used to eliminate the flare with the sun coming in at a one o'clock angle.
