Voigtlander 21mm f1.4 Nokton Aspherical - E-Mount

No, this is a manual focus lens. You must adjust the focus ring to achieve sharp images.

The Voigtlander 21mm f/1.4 Nokton Aspherical has a filter thread size of 52mm.

This lens is compatible with all Sony E-mount mirrorless cameras, including full-frame and APS-C models.

The aperture is controlled by the camera's settings. The lens does not have an aperture ring.

The minimum focusing distance is 25cm (9.8 inches).

The Voigtlander 21mm f/1.4 Nokton Aspherical is not officially weather-sealed, so it is recommended to protect it from rain and dust.

A lens hood and a UV filter are recommended for protecting the lens from scratches, flare, and dust.

Ensure the lens is properly focused manually. Check for camera shake and use a faster shutter speed if necessary. Verify the aperture setting; wider apertures (lower f-numbers) have a narrower depth of field, so focus is more critical.

The focus ring should rotate smoothly. If it is stiff, the lens might need professional cleaning and lubrication, or the focus ring could be damaged.

Make sure the lens is securely mounted to the camera. Check the camera's settings to ensure manual focus lenses are enabled. Inspect the lens contacts for any dirt or damage.

Ensure the subject is in focus. Stop down the aperture (increase the f-number) to increase the depth of field. This issue can also be caused by lens flaws, which may require replacement.
