Legendary Zeiss Planar Design
The famous symmetric lens design invented by Dr. Paul Rudolph at ZEISS in 1896. The Planar lens is the most successful camera lens design – and, by the way, the most plagiarized – ever created. It provides the lens designer with numerous means to correct aberrations extraordinarily well. And its performance is very constant over a wide range of imaging ratios, enabling such a versatile lens variety as the Makro-Planar lens.
- Makro Planar with 14 lens elements in 11 groups
- Lens with aspheric optical surface
- Lens made of special glass with anomalous partial dispersion
- "Floating Elements" design
- Smooth and reliable autofocus
1:1 macro capability
The Touit 2.8/50M lets you capture the smallest things and the tiniest details at their actual size. At its closest focusing distance, subjects sized 15x23 mm fill the frame with an impressive maximum reproduction ratio of 1:1. The imaging performance of the Touit 2.8/50M is just as exceptional at such short distances as it is at medium and long distances. Minimum distortion, outstanding correction of chromatic aberrations, minimal image field curvature and excellent correction of coma and astigmatism allow true-to-life reproduction of any subject, particularly in combination with the high resolving power of modern sensors.
The ZEISS Touit lenses are designed and constructed specifically for use on Sony NEX and FUJIFILM X Series cameras with APS-C sensors. The lenses are therefore fully-compatible and support all camera functions, including autofocus.
