It's the first dedicated macro lens for Sony's full- frame E-mount cameras, but just how good is the new Sony FE 90mm f/2.8 Macro G OSS lens? Richard Sibley has a closer look.

The 90-105mm focal length is a sweet spot for macro photographers. It offers a good working distance between the subject and the end of the lens, and has a narrow enough field of view so that backgrounds can be fairly concentrated and blown nicely out of focus.

Thanks to the E mount's short flange distance, Sony Alpha 7 cameras are able to use many lenses originally designed for DSLRs. Of course, this facility equally applies to other compact system cameras, but thus far, Sony is the only company to offer a full-frame sensor.
