Giving a perfect view of small things. The Touit 50mm f/2.8 Sony E Mount Lens is a prime telephoto lens with a M52 x 0,75 Filter thread for compact cameras with APS-C sensors. It has a focus range of 0,15 m (6.02 ″) – ∞ and a coverage of 23,5 x 15,6 mm (0.93 x 0.61") at close range letting you capture the intricate network of veins on a leaf and each strand of hair standing on a dandelion. Sporting a 50 mm focal length this lens can shine, not only in macros, but also in taking portraiture and panoramic shots. The f/2.8 to f/22 aperture range, gives you the power to adapt to any lighting conditions. Also, the Makro Planar with 14 lens elements in 11 groups delivers consistent high quality performance even down to the minimum object distance. You don't have to worry with picture distortion or chromatic abberation with its lens made out of special glass with anomalous partial dispersion and aspheric optical surface. It is compatible only with APS-C DSLR Cameras.
Product Features in Detail
Planar Design
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.
Smooth and reliable autofocus
The design of the autofocus system demands an extremely precise movement of certain lens elements. As the mass of the elements or groups to be moved within the optical system differs, various motor types may be installed. The focusing system of the Touit lenses is designed to guarantee robust and smooth autofocusing without any need for compromises or limitations in their optical design.
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.
Full compatibility
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.
Excellent resolution and high contrast
Rich, vibrant colors are vital to creating a lasting impression. Stray light in the lens, however, would lead to a brightening of the image, which is particularly visible in shadow areas. Image contrast is lowered; the image appears dull and bleached. We combine various, elaborate techniques to reduce unwanted stray light.
Floating Elements Design
The latest floating element design principles, optical aberration effects in ZEISS lenses are reduced to a minimum throughout their entire focusing range. This is achieved by variation of the axial distance between individual lens elements or groups. This adjustment of the lens-to-lens distance is coupled to the distance setting to ensure correct compensation at all times. The mechanical construction of these lenses is extremely complex and they must be assembled with utmost precision – both of which are key competencies of ZEISS.
Ideal aperture characteristics
The Touit lenses feature a nine-blade iris that closes to create an almost perfectly circular aperture. The effect of this is the creation of a particularly harmonious effect in the out of focus areas of the image (‘Bokeh’)
