Lens Mount Adapter Buying Guide

A lens mount adaptor essentially offers the photographer the opportunity to attach a lens to a specific camera. This may be from one type of lens of the same brand to a different model or from brand to brand. Obviously, this means a photographer may be able to use an existing lens when switching cameras or brands or to purchase a lens with certain features that is not specifically designed for the camera make or model owned. When looking for a lens mount adapter, it is important to match and check all features. For durability it is usually advised to purchase an adapter that is all metal. Adapters should allow the lens to be focused to infinity and this may sometimes present a problem for particular brands, but options are available. Where possible, it is a good idea to purchase an adapter for every lens as this saves on continuously swapping an adapter over. This guide mostly covers lens mount adapters for SLR/DSLR camera and lenses although adapters can also be found for other camera types too.
