It´s been written by many other users of the prime lens 60mm Macro: it´s not the fastest. It´s annoying how the AF is hunting even in bright light when using the macro mode. But the IQ is great, when you finally got the shot.
The pictures were shot with my X-E2 and a wide open lens at f/2.4 up to ISO 6.400. Provia filmsimulation, converted to black and white in LR 4.4.
