I love the len
優點:
-Sharp, natural color.
-the power zoom is alot better than i hope for. its smooth and although it change focal length slower than 18-55 PZ its way more control-able. I was worry with power zoom in real world use its good.

缺點:
-the distortion in long focal length is very noticeable but in camera (Nex6) jpec or Lightroom already have auto correct profile of this lens for RAW.
-the lens always change back to 18mm when power off (not a big issue) or in power saving mode (big issue if i know i am doing long shots and it goes power saving mode I need up need to change focal length again when i press the shutter button to wake it up again. I suppose you can change the power saving mode i guess.
Its a Fix F4 but when i zoom to longer focal length less light enter to the sensor. Say if i keep 1/125 , F4 and put it on auto ISO, at 18mm in a room it can be ISO 1600 at 18mm and change to ISO 2000 at 105mm. Maybe I am new to photography but thats how i observe.

評價:
I have yet to test more on power usage. PDAF seems not supported hope there might be patch to fix that. I think it focus same speed is kinda same as the SEL 35F18 or the Sigma 19mm Fixed length of the len. The size is a little large on a Nex 6 I still think its a very good walk around len(at least its fixed size not like the 18 200 LE or the 18 200 AE), sharpness is great, power zoom is implemented great.
