Perfect for macroMACROProducing photographs that render extreme close-ups of extremely small subjects like insects, hence its popularity among nature photographers. It requires using a macro lens with a large reproduction (magnification) ratio of at least 1:1, which renders a subject larger than life size. Macro lenses are capable of focussing at extremely short distances (some as little as a few centimetres), allowing the photographer to get very close to the subject. photography and closeup portraits

Canon Extension Tube EF 25 is recommended for lenses with a focal lengthFOCAL LENGTHMeasured in mm, it is the distance from the focal point of a lens (its centre or curved mirror where light converges) to the plane of the image sensor (film) when an object is in focus. A shorter focal length lens sees a wider image and a longer focal length brings your subject closer. For example, a 15mm lens sees a very wide image and is perfect for landscape photography. Conversely, a 500mm lens sees a very narrow image, brings the subject much closer and is thus great for subjects that are far away, like a bird in a tree. With zoom lenses, its minimum and maximum focal lengths are indicated, for example, as 24-105mm. A zoom lens allows you to change the lens’ focal length, with shorter (wide-angle) and longer (telephoto) options, whereas a fixed focal length lens requires you to move back and forth to find the correct image composition. of 50mm and up. (Note that the EF-S 18-55mm can be used at middle and tele zoom settings.) 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 exposureEXPOSUREExposure is controlled by three elements: Aperture, Shutter Speed and ISO. Achieving the correct exposure is similar to collecting rain in a bucket, up to an optimum level. The rate of rainfall is out of your control (light), yet you can control these three factors: the bucket’s width (lens aperture), the duration you leave it in the rain (shutter speed), and how effective your bucket is in collecting rain (ISO). These three elements work together to control the amount of light per unit area, preventing underexposure (too dark) or overexposure (too bright), giving you a natural looking image. compensation will be required (exposure compensation is required for handheld meters). This extension tube is compatible with EF-S lenses, as well as EF and TS-E lenses.
