Carl Zeiss, or just Zeiss, has presented at the Photo Plus Expo in N.Y. their third lens for CSC cameras. This lens is classified under the "Touit “series, and is known as "Touit 2.8/50M", which is Zeiss’ first macro for Fujifilm and Sony’s CSC cameras.
The version of this new device for Sony’s E mount won’t cover the 24×36 mm format of the new Alfa 7R and Alfa7, but will cover the APS-C sensors of the new NEX cameras that use the same mount, and in this case the lens will be equivalent to a focal length of 75 mm.
When used in the new Sony Alfa 7R and Alfa it will be capable of “cutting” pixels.
When used with the X series cameras from Fujifilm, the new Zeiss Touit Macro 50 mm f/2.8 and its 75 mm equivalence can be used with no issue with the X-Pro1, X-E1, X-E2, X-M1 and X-A1, though thanks to its price, it seems to be more compatible with the first three models.
The new Zeiss Touit Macro 50 mm f/2.8 is very similar to its two predecessors, featuring the trademark speed and smoothness of them, though it is a bit slower.
However, the engine used in the focus system speeds everything up, and like almost every macro lenses, most users prefer manual focusing.
According to the manufacturer, it has a metallic keg, though the guys at DSLR Magazine said it will feature the same hybrid composition of the two previous Touit.
After laying hands on it, we can confirm is excellent design, not unlike the previous Touit, and has a metallic keg.
The manual focusing is silky smooth, however much of the optical barrel has been occupied by the focus ring.
When we talked to Ken Nagate –Senior Department Manager of the lens department of the company–, he told us that the inside of the device is very similar to that of the brand new Otus. It has been carefully designed, it feels solid, robust and precise, both in MF and AF, and it avoids internal reflections, something critical in macros when they get to 1:1.
It seems the prestigious cinema series CP.2, manual focus lenses, has given them a lot of experience in regards to materials and components.
Since this is a 50mm f/2.8 capable of reproducing 1:1 in APS-C, it can be considered the first of its kind. This new lens from Carl Zeiss is very small and elegant-looking.
However, we couldn’t measure the speed and other details about it, since it only a preview model. We’ll have to wait until we can test the final version of this formidable device.
