While your lens’ minimum aperture will determine how deep you can make your depth-of-field and as well as how your lens will perform in bright conditions.įor the Nikon lens and the Canon lens, the maximum aperture is identical: f/1.8.īut, the Nikon 50mm f/1.8 lens has a minimum aperture of f/16 the Canon EF 50mm f/1.8 STM lens has a minimum aperture of f/22. Your lens’ maximum aperture will determine how shallow you can make your depth-of-field, as well as how well the lens will perform in low light conditions. Know Your Maximum and Minimum Apertureīeing knowledgeable of your lens’ maximum and minimum aperture is always helpful. So, when planning to shoot with your 50mm take the space of your location into consideration and make an extra effort to find open areas to photograph in. In this case, your viewing angle will shrink to 31 degrees, which is about equal to that of a 75mm lens used with a full-frame camera. This gets even more problematic if you’re using your 50mm with a cropped sensor camera. When you’re using a 50mm lens, shooting in wide, spacious areas is often ideal.Įven with a full-frame camera, a 50mm lens only allows you to work with a viewing angle of 46-47 degrees, which often makes shooting in confined areas difficult. To be sure, look up the specs when you are purchasing or do a quick google search to confirm. It is not always clear whether a lens has a motor or not. Generally speaking, beginner cameras omit an internal focusing motor and you’ll need to use a lens with a focusing motor. If you have a camera with a built-in focusing motor you won’t need a lens with a focusing motor. If your lens doesn’t have a focusing motor, it’s imperative that you use a camera that does. The Nikon 50mm f/1.8 and the Canon EF f/1.8 STM lenses feature built-in focusing motors. This is a key factor to double-check before you shoot. Some lenses have built-in focusing motors, but others don’t. Check Your Camera’s Focusing MotorĪ focusing motor is a feature in lenses and cameras that gives you the ability to facilitate automatic focusing. If you don’t find it on your lens, try doing a simple Google search to find out. The location differs depending on the lens, but some common places you can look at are near the focus distance display, on the face of the front ring, or around the mount. If you’re using a different lens brand, you should be able to find the minimum focusing distance labeled on your lens. The Nikon 50mm f/1.8g lens has a minimum focusing distance of 0.45m/1.5ft from the focal plane mark.įor Canon EF 50mm f/1.8 STM lens, the closest focusing distance is 0.35m/1.15ft. Most DSLR cameras will mark this point with a line through a circle (pictured below). The minimum distance is calculated from the camera’s focal plane mark, typically found near the shooting mode dial. Getting closer to your subject than the minimum focusing distance will render it out-of-focus and blurry. This is the shortest distance in which your lens can focus. Experiment Shooting Under Low-Light ConditionsĪll lenses have a minimum focusing distance.
