Description

Details

The Sony Sonnar T* FE 35mm f/2.8 ZA lens is a compact, high-quality E-mount lens ideal for the Sony ILX-LR1 Industrial Camera. This superb wide-angle lens has a bright F2.8 aperture, three double-sided aspherical elements to minimize aberration and a T* lens coating for natural color representation.

Unsurpassed Visual Clarity

This lens leverages Sony’s innovative Sonnar optical design to produce remarkable levels of clarity and elemental suppression. The performance is simply unmatched, a feature especially amplified when used in synergy with the Sony ILX-LR1 Industrial Camera and UAV drone surveillance and inspection

Circular Aperture

Light sources will appear defocused when adjusting the aperture to blur the background. The Sony Sonnar T* FE 35mm f/2.8 ZA lens utilizes circular aperture blades to enhance the 'bokeh' effect, avoiding the unattractive polygonal shapes created by conventional flat-sided blades. With its unique design, α lenses maintain an almost perfect circular aperture from wide open to 2 stops closed, resulting in a smoother and more natural defocusing.

Aspherical Lens Elements 

The aspherical lens design effectively minimizes spherical aberration, resulting in a smaller and lighter lens. The misalignment of light rays on conventional spherical lenses, known as "spherical aberration," can degrade image quality in larger-aperture lenses. To correct this, aspherical elements are strategically placed near the diaphragm to realign the light rays and maintain sharpness and contrast even at maximum aperture. They can also be used at other points in the optical path to reduce distortion.

Additionally, well-designed aspherical elements can decrease the total number of elements needed in the lens, ultimately decreasing its size and weight. The Advanced Aspherical (AA) elements, with their high thickness ratio between the center and periphery, are a superior version that requires advanced molding technology to achieve precise shape and surface accuracy, resulting in highly accurate and quality images. 

Carl Zeiss T* (T-star) Coating

This exceptional lens showcases the renowned Carl Zeiss T* (T-Star) coating, which Carl Zeiss® first pioneered. This advanced coating effectively eliminates lens flare, internal reflection, and light scattering that may occur at glass-to-air surfaces. It significantly contributes to superb image quality, providing exceptional contrast and uniformly excellent resolution even at the edges. The T* coating is selectively applied to multi-element lenses that have met the required performance standards across the entire optical path, ensuring the highest level of quality.

Dust and Moisture Resistant

This lens is designed to withstand dust and moisture, making it ideal for rugged outdoor use. It pairs perfectly with weather-resistant cameras for even better protection.

Internal Focusing

The optical system of this lens achieves focus by moving only the middle groups, keeping its overall length unchanged. Other notable advantages include quick autofocusing and a close minimum focusing distance. Additionally, the front filter thread remains stationary, making it easy to use a polarizing filter.
