Close Up Filters are used when you need to extend the camera's focusing range into the close up range. These convex lenses (+) shorten the focal length while maintaining the same distance setting. They are available in the most popular screw-in sizes. Close Up Filters can be combined to obtain greater strengths. No exposure correction is required. The following strengths are available: NL 1.0, NL 2.0, NL 3.0. The higher the number the closer you can focus. For best results stop down to f 5.6 or f8.

Minimum focus distance with no close up filter	Minimum focus distance with Close Up Filter 1
Minimum focus distance with Close Up Filter 2	Minimum focus distance with Close Up Filter 3

Please note: The images above are for demonstration purposes only. Results will vary depending on the focal length and minimum focus distance of the lens.

About Heliopan Filters

Whether for analog or Digital Photography: The best results are achieved by using correction filters - not by digitally enhancing in a software program as once undesired light parts are included in the image information a correction can only be achieved by reducing quality, if at all. For example, a simulated IR effect will always remain a simulation and softness from UV radiation in the blue channel, if no filter is used, will occur. The filter program from Heliopan, made in Germany, allows you to produce images of the highest quality, right from the start.

For brilliant color reproduction, highest contrast and sharpness Heliopan offers:

The highest quality optical glass from the German Schott Group The longest life expectancy thanks to brass filter rims Minimal reflections because of matte black filter rings At least one high quality hard coating on each filter side to reduce stray light, to maintain high contrast and to avoid flare (Reflections are reduced from 8% to only 2.5% for each glass to air surface on each side of the filter).
