Zeiss Batis 40mm f/2 Distagon T* CF Autofocus Lens for Sony E Mount {67}

Zeiss Batis 40mm f/2 CF: the one-lens answer for Sony mirrorless shooters.

At 40mm, the Batis CF sits in a focal length that most photographers walk past, just wide enough to work a room, just tight enough to isolate a subject. The f/2 maximum aperture gives you workable light separation at a distance while the 24cm minimum focus distance, paired with 0.3x maximum magnification, lets you get close enough that macro-adjacent shots are genuinely on the table. That CF designation earns its keep through a floating elements system that keeps optical performance consistent whether you're focused at arm's length or across a table.

The Distagon optical design uses 9 elements across 8 groups, with both aspherical and anomalous partial dispersion elements doing the work of controlling chromatic aberration and distortion before they become problems. T* anti-reflective coating handles flare and ghosting in backlit and mixed-light situations. Weather sealing keeps it field-ready. The OLED display on the barrel showing live distance and depth-of-field readouts is a genuinely useful tool, particularly for zone-focusing or precise near-subject work.

At 361 grams with a 67mm filter thread and internal autofocus, this lens disappears into a single-bag travel kit. Sony mirrorless shooters who want one lens that can move between street scenes, dinner tables, and product work without a bag change have a proven option here.

Who It's For

Travel photographers who shoot one-bag light will appreciate the 361g weight alongside a focal length that handles environmental portraits and tight interior scenes without switching glass. Documentary and street photographers benefit from the internal autofocus motor's quiet operation and the 40mm field of view that keeps subjects from feeling the lens. Food and product photographers gain from the 24cm minimum focus distance combined with f/2 subject separation. Landscape shooters working in rain or dust can rely on the weather-sealed construction without carrying a second body for protection.

FAQ

What makes 40mm a useful focal length for a travel kit?

At 40mm you're between a standard 50mm and a wider 35mm-wide enough for environmental shots and small spaces, but tight enough to compress backgrounds and isolate subjects without cropping aggressively. It's the lens length that works a room without forcing you to step back constantly.

How close can you focus, and what's the magnification?

24cm minimum focus distance with 0.3x magnification. That's close enough for product shots, tabletop work, and detail-oriented framing, though not true macro territory. The floating elements keep optical performance steady from that 24cm distance all the way to infinity.

What does the OLED display on the barrel actually show?

Distance and depth-of-field readouts in real time. It's particularly useful for zone-focusing or when you're working near the minimum focus distance and need to confirm your DoF envelope without looking at the camera's rear screen.

Does this lens have image stabilization?

No. At f/2 and 40mm, you're workable down to around 1/40th on a steady hand, or you bump ISO. If you need stabilization, you're leaning on your camera body's in-body system.

Is autofocus fast and quiet for video or stills?

Autofocus is internal and designed for Sony mirrorless bodies. It's responsive for stills work. Video autofocus behavior depends on your camera's AF implementation and whether you're using continuous or single-shot mode.

How weather-sealed is this lens?

It's sealed against dust and moisture. It's not a diving lens, but it handles field conditions-rain, sand, salt air-without requiring babying. The hood ships with it.

Can you manually focus while in autofocus mode?

Yes. Full-time manual focus means you can twist the focus ring at any time, whether AF is active or not. No mode switching required.
