The Samyang 500 mm MC IF f/8 Mirror is a manual focus lens, The fixed f/8 aperture means there is no aperture settings on the lens to worry about. Due to the very narrow depth of field with such a long focal length it is recommended to focus with live-view to achieve accurate focus. As with all long telephoto lenses a combination of sturdy camera support / tripod, good technique, fast shutter speed, and using a remote where possible is recommended to avoid camera shake to achieve the best results. For moving objects pre-focusing on a point and allowing the subject to reach that point may yield better images.

Suitable for full frame and cropped sensors, on a 1.5x cropped sensor such as Nikon will yield a 750mm focal length equivalent, or 800mm on 1.6x cropped DSLRs such as Canon EOS digital SLR camera series.

There is a optional 2x converter (available separately) increasing the actual focal length to 1000mm. (giving 1500mm on Nikon 1.5x cropped sensor, etc)
