We were blown away in 2018 when Laowa launched its 24mm f/14 2x Macro Probe lens - a macro lens like no other. Then in 2022, AstrHori gave us its 28mm f/13 macro probe lens, offering similar specs to the Laowa lens, but costing around half the price. And just when you thought there were enough probe lenses in the world, AstrHori announced it has another offering waiting in the wings - this time a dedicated APS-C probe lens. The crop-sensor lens will be available in Sony E, Fujifilm X, Canon RF, Canon EF, Nikon Z, L-mount and Micro Four Thirds mounts.
As you'd expect from a lens with such a range of mount options, it is a manual focus-only optic, likely lacking any electrical contacts to communicate with the host camera. The lens offers up to 2x magnification and has a minimum focus distance of 0.47m - but due to its long length actually has an effective working distance of just 5mm.
The beauty of a probe lens is that you can stick its snout right into the action to capture a bug-eye perspective in the depths of the undergrowth, while its wide-angle field of view also maintains a greater depth of field to record more background context. The front section of the probe is waterproof, allowing you to use it for underwater images in streams or fish tanks.
The lens's unusually narrow barrel keeps it (and you), fairly inconspicuous to your subject, and judging by the leaked lens images, the AstrHori 18mm probe lens features a tiny LED ring light around the front lens element to illuminate close-up subjects – a feature shared with the 28mm version.
