Laowa 25mm f2.8 2.5-5X Ultra-Macro Lens - L Mount

The Laowa 25mm f2.8 Ultra-Macro Lens offers an adjustable magnification range from 2.5x to 5x life-size.

No, this is a fully manual lens. You will need to adjust focus and aperture using the rings on the lens.

This lens is designed for cameras with an L-Mount, commonly found on full-frame mirrorless systems.

The working distance varies with magnification. At 5x magnification, the working distance is approximately 10-15mm. At 2.5x, it is around 40-45mm.

While technically possible, the 25mm focal length and extreme macro capabilities make it less ideal for general-purpose shooting compared to dedicated standard lenses. Its strength lies in extreme close-up work.

Compared to longer macro lenses, the wider 25mm focal length provides a relatively greater depth of field at the same magnification. This can be beneficial for focus stacking.

The closest focusing distance is 0.173 meters (17.3 cm), but this is when the lens is set to its lowest magnification of 2.5x. At higher magnifications, the subject will be much closer.

Ensure you are using an L-Mount camera and that the lens and mount are clean and free of debris. Align the mounting indicators correctly.

The lens is fully manual. Practice using the manual focus ring and observe focus peaking or magnification aids on your camera. Ensure you are within the lens's focusing range and have selected the appropriate magnification.

This is expected for a fully manual lens without electronic contacts. Switch your camera to Manual (M) mode and enable 'Shoot without lens' or a similar setting in the camera's custom functions if available.

Ensure the lens elements are clean. Check that the aperture is not set too wide open (f/2.8) or too stopped down (f/22), as optimal sharpness is often found in the mid-range apertures. Verify correct focus and magnification.
