Review

The AstrHori 25mm f/2.8 2-5x Ultra Macro lens for Canon RF mount is an intriguing option for macro photography enthusiasts who are keen on exploring the minutiae of the natural world with exceptional detail. This lens pushes the boundaries of macro capabilities, allowing for magnification ratios that can reach up to 5x, which is quite impressive compared to standard macro lenses.

Build Quality and Design

The lens features a metal construction that feels robust and well-engineered. It sports a compact and lightweight design, making it portable for outdoor macro shooting. The smooth manual focus ring allows for precise adjustments, essential when dealing with such high magnification. However, the absence of autofocus might be a drawback for those who prefer quicker, automated shooting, especially in dynamic environments.

Optical Performance

When it comes to image quality, the AstrHori 25mm f/2.8 doesn’t disappoint. The lens delivers impressive sharpness, especially at its sweet spot of f/5.6 to f/8, where details pop and textures are rendered beautifully.

However, it’s worth noting that performance can decline slightly at the maximum aperture of f/2.8, with some softening evident at the edges.

Versatility and Use Cases

One of the strengths of this lens is its versatility in macro photography. Its unique magnification capability opens up a wide range of shooting possibilities, from small insects to intricate details of flowers. The working distance is decent, allowing for some space between the lens and your subject, which is a boon when photographing live subjects like insects that can be easily disturbed.

Compatibility

Designed for the Canon RF mount, this lens is compatible with the latest Canon mirrorless cameras. While it doesn't have electronic communication with the camera, this doesn't detract from its effectiveness as a pure manual focus lens. Users of Canon RF cameras will appreciate this lens but may find it lacking if they heavily rely on electronic features for exposure settings.
