Interesting focal range that takes exactly the relay 10-30 mm supplied with the unit. Fast focus, relatively light and, for once, delivered with visor. Very good performance in absolute terms, but relative to excellent 18.5 mm and 32 mm, do not allow it to get the fifth star. Request a certain technique if we want to get to restore proper background blur. Rest in combination with the zoom 10-30mm mentioned above, it covers almost all focal lengths required for the amateur, for a reasonable bulk and weight.
