Build chất lượng is excellent, with both a metal lens barrel & a metal lens mount, but you"d expect that given the high price of the lens. The wide, ridged zoom ring takes about a quarter of a turn to lớn zoom through the range, with the lens gradually extending out until it reaches 70mm.

The manual focus ring is a little on the slim side, and utilises the NEX series"s fly-by-wire operation, which means that there are no hard stops at either kết thúc of the zoom range.

There"s also no depth-of-field scale, distance scale or infrared index, a shame given the cost of the lens.

We didn"t experience much "hunting", either in good or bad light, with the lens accurately focusing almost all of the time, and it"s also a quiet performer thanks to lớn its in-lens motor, ideal for HD movie shooting.
