Lens Overview — AstrHori 28mm Macro Probe Lens

The AstrHori 28mm Macro Probe Lens is a specialized manual focus prime designed for close-up and macro photography. Built around a 28mm focal length with a maximum aperture of f/13, this full-frame compatible lens takes a distinctly utilitarian approach — prioritizing working distance and access over speed. The probe-style form factor is the defining characteristic here, allowing photographers to position the front element in spaces that a conventional lens barrel simply cannot reach, opening up creative possibilities in product photography, nature work, and experimental macro shooting.

With a fixed focal length of 28mm, there is no zoom functionality, keeping the optical path straightforward and the lens dedicated entirely to its macro purpose. Manual focus is the only option, which is standard practice for serious macro work where precise, deliberate focusing is essential. The lens covers a full-frame image circle, meaning it can be used on both full-frame and smaller-sensor mirrorless bodies without vignetting concerns.

At 700g, it has a solid, substantial feel. Broad mount compatibility across Canon EF, Nikon F, Sony E, and Micro Four Thirds systems makes it accessible to a wide range of shooters regardless of their camera ecosystem.

Key Features — AstrHori 28mm Macro Probe Lens

Probe-Style Form Factor: The elongated tubular barrel allows the front element to reach into confined spaces that conventional lens designs cannot access, opening up unique macro angles in product, nature, and experimental photography.

28mm Full-Frame Prime: Fixed 28mm focal length covers a full-frame image circle, so it can be used on both full-frame and smaller-sensor bodies without vignetting.

f/13 Maximum Aperture: The narrow maximum aperture is typical for probe lens designs, providing greater depth of field at close focus distances where macro work demands sharp subject coverage.

Manual Focus Only: Dedicated manual focus control allows the precise, repeatable adjustments that close-up and macro shooting requires.

Close-Up Working Distance: Designed specifically for macro and close-up photography, the probe format allows the front element to be positioned extremely close to or even inside a subject.

Broad Mount Compatibility: Available in Canon EF, Nikon F, Sony E, and Micro Four Thirds mounts, making it accessible across a wide range of camera systems.

Description — AstrHori 28mm Macro Probe Lens

The AstrHori 28mm Macro Probe Lens is a prime, manual focus lens built specifically for macro photography. With a focal length of 28mm and a maximum aperture of f/13, it is engineered for close-up work rather than low-light shooting, prioritizing the probe-style form factor that gives it access to tight and confined spaces where conventional lenses cannot reach. The lens covers a full-frame image circle, ensuring compatibility with both full-frame and smaller-sensor bodies across its supported mounts.

Speaking of mounts, it offers broad compatibility — available for Canon EF, Nikon F, Sony E, and Micro Four Thirds systems — making it one of the more versatile macro options in terms of ecosystem support. Designed for mirrorless camera systems, the lens weighs 700g and has no filter thread, so standard screw-on filters cannot be attached. There is no image stabilization, so a sturdy support system is advisable.

Focus is entirely manual, which suits the deliberate, controlled technique that precision macro photography requires.
