9 out of 10 points and recommendedsharp, good contrastN/A
The Sony E 16-70mm F4 is an excellent lens. It is sharp and high contrast at ALL focal length and ALL aperture. Usually, a zoom lens tend to be soft at the tele end and wide open. The Sony 16-70 is very sharp at 70mm F4. I can do nice portrait shots at 70mm f/4 but I have to set the 18-55 kit lens to F8 at 55mm because the kit lens is very soft at 55mm F5.6. I cannot get nice bokeh with the kit lens. The 16mm is very nice, too. In real life, the contrast is always on high level.reviewed August 20th, 2014
Is it expensive at $1000? No. The Olympus 12-40 f/2.8 is in the same price range. The M43 f/2.8 gives similar bokeh as the f/4 on APS-C sensor. The DSLR Nikon 16-85 f/3.5-5.6 is $700 but it is not constant f/4.
