![]() ![]() Wide-angle, macro and fisheye conversion lenses are quite common. Typically these are used to offer specialised capabilities without having to use a dedicated lens. Auxiliary and conversion camera lenses are designed to attach to a camera lens in order to alter its optical characteristics. Lens AdaptersĪnother type of adapter that can be found in many camera bags is the conversion camera lens. Some adapters also feature electrical contacts to preserve electronic communication between the lens and the body, allowing continued use of autofocus, aperture control and image stabilisation. ![]() Some more advanced adapters feature their own glass elements in order to overcome excessively long flange focal distances and provide infinity focus. Simple adapters are versatile but limited, which is why many photographic equipment manufacturers also produce more complex adapters in order to get around those limitations. Extension tubes take advantage of this same principle to achieve a closer minimum focusing distance for macro photography More Advanced Adapters These adapters can also not be used to adapt lenses designed for a shorter flange focal distance to a larger body, at least not without losing the ability to focus all the way out to infinity. This makes them unsuitable for use with lenses that do not have a mechanical aperture ring. These adapters do not include electrical contacts, and so aperture and focus need to be set manually. The simplest form of lens adapter is a metal or plastic ring that fits between the lens and the lens mount to position the rear lens element at the appropriate distance from the digital sensor. Lens mount adapters are even available for vintage camera lenses that are no longer supported by any manufacturer, so you can use them with modern cameras. A lens adapter allows photographers to mount lenses designed for one mount on a camera with a different type of mount, for example by attaching a Nikon lens adapter to a Pentax camera. Different camera manufacturers use different shaped lens mounts in order to ensure that their cameras are used with their lenses. It provides a secure attachment point for lenses in order to keep them safely attached during use. ![]() The lens mount is an essential part of any interchangeable lens camera. They grant access to a wider selection of lenses as well as sometimes enhancing the capabilities of existing lenses. Camera lens adapters and tubes can be used to increase the already impressive level of versatility given by interchangeable lens cameras. ![]()
