The Zeiss Makro-Planar T* 50mm f/2 is one of two macro lenses in the Zeiss Z-lineup.
The lens is currently available in Nikon F, Canon EOS and Pentax-K mount. We've
tested the ZF version via an EOS adapter but the optical design is, of course,
identical regardless of the target system.
The build quality of the full-metal Zeiss (brass with chromium-plated brass front
bayonet) is superb. The fluted focus ring feels exceptionally well damped.
A lens hood is part of the package as you may notice below. However, the front
element is deeply recessed from the filter thread so you don't really need one
Z-series lens don't offer AF. However, the focus confirmation in the viewfinder
remains active and it is, of course, possible to check the focus via Live-View
(or a split-image screen).
Typical for most macro lenses the focus design is a combination of an extension
system and floating elements for close-focus correction. It takes a ~300 degree
turn of the focus ring to reach the closest focus from infinity and in the
process the length of the lens increases by 32mm. The working distance (front
element to object) is about 9cm here. Unfortunately the max. object magnification
is only 1:2 whereas most of the competitors offer 1:1. On the other hand it's
the only full format 50mm macro lens as fast as f/2.
