Review of Sony Vario-tessar T* E 16-70mm F/4 Za Oss Lens
Introduction
The Carl Zeiss Vario-Tessar T E 16-70mm f/4 ZA OSS (SEL1670Z) is a premium standard zoom lens for Sony NEX compact system cameras. It offers the equivalent angle of view as a 24-105mm lens on a 35mm camera and features a almost-circular 7 blade diaphragm which creates an attractive blur to the out of focus areas of the prototype. The optical formula comprises 16 lens elements in 12 groups. It has a minimum focusing distance of 35cm/ane.15ft and a maximum magnification of 0.23x. Sony's DMF applied science allows for straight manual focusing after autofocus lock-on without having to switch modes, while the congenital-in Optical Stabilisation organization offers up to 4 stops of compensation. The Carl Zeiss Vario-Tessar T E 16-70mm f/4 ZA OSS lens is currently bachelor for £849 / $999 in the Uk and the US, respectively.
Ease of Use
Weighing in at 308g, the alloy-bodied Carl Zeiss Vario-Tessar T E 16-70mm f/4 ZA OSS is quite a substantial Eastward-Mount lens that rather dwarves the compact Sony NEX-7 body that nosotros tested it with, as shown in the photos below.

Build quality is excellent, with both a metallic lens barrel and a metal lens mount, only you'd expect that given the high price of the lens. The wide, ridged zoom ring takes about a quarter of a plough to zoom through the range, with the lens gradually extending out until information technology reaches 70mm.
The manual focus band is a little on the slim side, and utilises the NEX serial's wing-by-wire operation, which means that in that location are no hard stops at either terminate of the zoom range.
There's also no depth-of-field scale, altitude calibration or infrared alphabetize, a shame given the cost of the lens.

Focusing is usefully internal and manual focusing is possible when attack the specific camera body. The lens also boasts Optical SteadyShot paradigm stabilization, which offers upwards to 4 shutter spee steps of compensation - again this is enabled through the photographic camera's menu system, rather than a concrete switch on the lens.

The Carl Zeiss Vario-Tessar T Eastward sixteen-70mm f/4 ZA OSS ships with a good quality example and a durable lens hood (ALC-SH127) which attaches within the lens barrel rather than exterior. Information technology accepts 55mm filters via plastic threads.
Focal Range
At the 16mm focal length the angle of view is 83 degrees.
Field of view at 16 mm
At the 70mm focal length the bending of view is 23 degrees.
Field of view at 70 mm
Focusing
The Carl Zeiss Vario-Tessar T E 16-70mm f/4 ZA OSS lens has quite a narrow focusing band. There are no difficult stops at both ends of the range, making it a fiddling more than difficult to fix focus at infinity. Polariser users should be pleased that the 55mm filter thread doesn't rotate on focus.
When it comes to motorcar-focusing, the Carl Zeiss Vario-Tessar T E 16-70mm f/4 ZA OSS zoom is a quick performer, taking about 0.2 seconds to lock onto the subject field when mounted on the Sony NEX-7 that we tested it with, although it is noticeably a little slower to autofocus at the 70mm end.
We didn't experience much "hunting", either in adept or bad light, with the lens accurately focusing nigh all of the time, and information technology'south too a tranquility performer thanks to its in-lens motor, ideal for Hard disk drive movie shooting.
Chromatic Aberrations
Chromatic aberrations, typically seen as majestic or blue fringes forth contrasty edges, are only notable by their almost complete absence from our test shots.
Light Autumn-off
With the lens set up to its maximum aperture, there is some lite fall-off in the farthermost corners at both ends of the zoom range, but information technology won't impact your real-world shots.

Macro
The Carl Zeiss Vario-Tessar T Due east 16-70mm f/4 ZA OSS isn't claimed to exist a macro lens, just it delivers a pretty skillful performance nonetheless. It has a minimum focusing altitude of 35cm/i.15ft and a maximum magnification of 0.23x. The following instance demonstrates how close you lot can get to your subject, in this case a Compact Flash memory carte.
Close-up performance
Bokeh
Bokeh is a give-and-take used for the out-of-focus areas of a photo, and is usually described in qualitative terms, such as smoothen / creamy / harsh etc. In the Carl Zeiss Vario-Tessar T E xvi-70mm f/iv ZA OSS lens, Carl Zeiss employed an iris diaphragm with seven rounded blades, which has resulted in highly-seasoned bokeh in our view. We exercise realise, however, that bokeh evaluation is subjective, so we've included several 100% crops for your perusal.
