Description
The Canon Extension Tube EF 25 II is a device that allows for shorter focusing distances when taking photographs. It is commonly used for macro photography and closeup portraits. This updated version is now compatible with both Canon Digital EF-S lenses and standard photo EF and TS-E lenses. It is recommended for lenses with a focal length of 50mm and up, but can also be used with the EF-S 18-55mm lens at certain zoom settings. The tube is designed to work with the camera's TTL metering system, eliminating the need for exposure compensation. It also features white and red index marks for different types of lenses.
The result of using extension tubes is that the distance from the back of the lens to the film surface is longer, which means you can take photographs at shorter distances to the subject. Extension tubes are thus commonly used for macro photography and sometimes for closeup portraits. When using the camera's TTL metering system, no exposure compensation will be required (exposure compensation is required for handheld meters). This updated version II is now also fully compatible with Canon Digital EF-S lenses, as well as standard photo EF and TS-E lenses. Extension Tube EF 25 II is recommended for lenses with a focal length of 50mm and up (EF-S 18-55mm can be used at middle and tele zoom settings).
