Zeiss Batis 40mm f/2.0 CF – fast f/2 aperture and compact full-frame coverage for Sony E-mount

The Zeiss Batis 40mm f/2 CF is a full-frame compatible lens designed for Sony mirrorless cameras. It combines a fast f/2 aperture with a focal length positioned between a moderate wide angle and a standard lens, making it versatile for many photographic situations.

Key uses and shooting situations

Use this lens for a wide variety of subjects. For example:

• Portraits — the 40mm field of view and f/2 aperture work well for subject isolation and natural perspective.
• Architecture and street photography — the slightly wide to standard focal length captures context while remaining compact.
• Documentary and everyday photography — the combination of size and image quality suits walk-around shooting.
• Close-up details and food photography — the close minimum focus of 24 cm allows you to capture small subjects and interesting details.

Smooth and reliable autofocus

The Batis 40mm f/2 CF uses an autofocus system engineered for precise shifting of specific lens groups. As a result, the lens delivers a robust and smooth-running autofocus mechanism. This design supports accurate focusing and helps maintain imaging performance across shooting conditions.

Built-in OLED display for focus info

A built-in OLED display shows both focus distance and depth of field at any selected aperture. Thanks to its high contrast, the display remains readable in bright daylight as well as in low-light situations. This feature helps you confirm focus quickly when working at different apertures and focusing distances.

Optical design and Zeiss characteristics

The optical layout contains 9 elements arranged in 8 groups. In addition, the lens uses the Zeiss T* anti-reflective coating. Together, these factors contribute to high contrast, sharpness, and color rendition commonly associated with Zeiss optics. Photographers who seek strong microcontrast even at wide apertures will find this lens meets that expectation.
