Sony India has recently introduced a new Super 35mm / APS-C format power zoom lens. Promising the uncompromising image quality, the power zoom lens starts at 18mm wide angle and extends to 110mm at the telephoto end (27mm – 165mm equivalent in 35mm format), with 6.1x high zoom ratio even with inner focus; while maintaining a constant F4 aperture throughout for depth of field effects and stable exposure control across the entire standard zoom range.
It consists of 18 elements in 15 groups, including 6 aspherical elements and 3 Extra-low Dispersion (ED) glass elements. It is also said to feature a highly intricate 7 blade circular aperture design that delivers extremely high resolution image quality, particularly suited to professional 4K movie shooting.
According to Sony, the SELP18110G is the second lens to benefit from Sony’s Smooth Motion Optics (SMO) design and construction. It has been reportedly developed to eliminate unwanted image shifts while operating the lens during movie shooting. Sony also stated that the SMO addresses three particular aspects on lens operation that can have a significant impact on movie quality: Focus Breathing, where shifts in angle of view during focusing are minimized by an internal focus mechanism; Focus Shift, where small shifts in focus that can occur while zooming are eliminated by precise focus tracking adjustment; and Axial Shift, where axial image shifts while zooming, are minimized by a constant length design.
The reportedly high level of operatability and quiet operation of the new lens make it a compelling proposition for its integration into professional movie production environments. Its three separate rings are said to offer control over focus, zoom, and aperture, with optimal torque for a satisfying responsive, professional feel. Both servo and responsive manual mechanical zoom are fully supported and the zoom ring direction is switchable to match individual user preferences. Sony has also informed that the lens length will remain constant during any changes making it easy to use with matte boxes and other lens accessories. A first for α lenses, the SELP18110G has a 0.8mm pitch focus gear built right onto the lens, providing direct compatibility with standard focusing accessories.
The SELP18110G is said to offer extra versatility thanks to Optical SteadyShot technology that will provide in-lens image stabilization during handheld shooting. Making the lens ideal for outdoor use, it is reportedly complemented by a dust and moisture-resistant design.
Sony has revealed that the SELP18110G Super 35mm / APS-C power zoom lens for professional movie-makers and photographers will be available in select Alpha Flagship stores and select Sony Center across India. The price of the SELP18110G ₹ 2,69,990 and the lens will be available from 10thMarch 2017 onward.
