Sony Alpha 3000 review – Third-party lens adaptors
One of the assets of the Sony E mount is its very short flange depth – the distance between the back of the lens mount and the sensor. Due to this, the distance can be extended using an adapter to allow almost any SLR lens to be used with an E-mount camera. A range of adapters is available from www.srb-griturn.com, and other companies online. These adapters allow users either to mount lenses they already own, or to buy new lenses cheaply and get an adapter to make them fit.
I used a manual Nikon F-mount 50mm f/1.4 lens, which cost around £80 second-hand. Connecting the lens to the adapter and the adapter to the camera was perfectly straightforward, and I was then able to shoot portraits with a fantastic lens. For the photographer on a budget, this is a good way to obtain great lenses at a cheap price.
However, most of these adapters lack the ability to autofocus or change the aperture of the lenses, so their use is generally limited to manual-focus lenses that also have an aperture ring.
