No name lens AstrHori AF 27 mm f/2.8 APS-C for Sony E mount

The AstrHori AF 27 mm f/2.8 is a compact prime lens designed for APS-C mirrorless cameras with the Sony E mount. With a fixed 27 mm focal length (equivalent to approx. 40.5 mm on APS-C), this lens provides a normal-angle field of view suitable for everyday photography, street scenes and travel. The f/2.8 maximum aperture balances low-light capability and a slim, lightweight form factor. The lens supports autofocus and is intended for photographers seeking a small, easy-to-carry optic for general-purpose shooting.

Advantages

The lens combines a moderate wide-normal focal length with a constant f/2.8 aperture, offering consistent exposure and depth-of-field control across common shooting situations. Its compact construction and low weight make it convenient for handheld use and travel. Built for Sony E mount APS-C bodies, it maintains autofocus compatibility and straightforward operation without the bulk of larger zooms.

Suitable for

• Street and documentary photography
• Travel and everyday carry
• Environmental portraits and casual portraits
• General-purpose snapshots and social media content

How to use

Attach the lens to a Sony E mount APS-C camera by aligning mount marks and turning until it locks. Use autofocus for most situations; switch to manual focus via the camera controls if fine adjustment is required. Set aperture to f/2.8 for shallow depth of field or to smaller apertures (higher f-numbers) for greater depth of field and sharper results across the frame. The focal length is well suited to shooting at eye level for natural perspective—move closer or farther from the subject to adjust framing rather than relying on zoom.

Usage recommendations

For balanced results, use shutter speeds that compensate for hand movement—generally 1/60 s or faster for handheld shots depending on focal length and stability. In low light, increase ISO or use the f/2.8 aperture while monitoring noise levels. For best image quality, stop down 1–2 stops from maximum aperture when higher sharpness across the frame is desired.
