Converter

What Does Converter Mean When Talking About Photography? A converter, also referred to as a tele-converter or extender is a secondary lens which can be mounted between a camera and main lens. The purpose of a converter is to magnify the central portion of a lenses image area, therefore increasing the focal length. Typically converters come in either 1.4 or 2.0 magnification factors. When using an extender the shooter will sacrifice a small amount of lens speed (-1 stop for 1.4 and -2 stops for 2.0) and autofocus performance will also reduce slightly. Extenders also magnify any distortion caused...

Macro Rail

What Is A Macro Rail? A macro rail is a mechanical rail system that allows you to move a camera fore and aft, or left and right, in extremely small and precise movements.  Depth of field can be incredibly thin when working at close distances with a macro lens.  Precise focus can be tricky to achieve, but with a macro rail, and the help of live view, it’s easy to fine tune the exact point of focus.  A system of gears ensures that you have incredibly precise and repeatable control.  Given the shallow depths of field in macro photography,...
