Sigma 15mm F1.4 DC Contemporary Lens - Sony E-mount

No, this is an APS-C format lens. While it can be mounted on a full-frame Sony E-mount camera, it will only cover the APS-C portion of the sensor, resulting in a cropped image. The effective focal length will also be longer in crop mode.

The minimum focusing distance is 17.7cm (approximately 7 inches) from the front of the lens. This allows for relatively close focusing within its wide-angle perspective.

The wide F1.4 aperture allows significantly more light to reach the sensor, enabling shooting in dark conditions with lower ISO settings and faster shutter speeds. It also creates a shallow depth of field for subject isolation and pleasing bokeh.

Yes, the lens features a 58mm filter thread, allowing you to easily attach standard 58mm filters such as UV, polarizing, or neutral density filters.

The lens is very lightweight, weighing only 220g.

The lens is constructed with 13 elements arranged in 11 groups, designed to provide high image quality for its specific focal length and aperture.

Yes, the lens is designed for both stills and video. Its wide perspective, bright aperture, and compact size make it suitable for various video applications, including vlogging and cinematic shots.

Ensure the lens is correctly mounted on the camera. Check that autofocus is enabled on the camera body and that the focus mode is set appropriately. Try manual focus to confirm lens functionality.

Verify that the correct aperture and shutter speed are set for the lighting conditions. Ensure the lens is focused accurately on the subject. Clean the lens elements with a microfiber cloth.

In low light, autofocus can be more challenging. Try pre-focusing on a high-contrast area or switch to manual focus. Ensure your camera's firmware is up to date.

Confirm that you are using a Sony E-mount APS-C camera. Check for any obstructions or damage on the lens mount or camera mount. Ensure the lens is aligned correctly before attempting to attach.
