Sirui Sniper Series 56mm F1.2 APS-C Autofocus Camera Lens - X Mount, Black

This lens is designed for mirrorless cameras with an APS-C image sensor and the Fujifilm X mount.

APS-C refers to the size of the image sensor. This lens is optimized for APS-C sensors and will produce a field of view equivalent to approximately 85mm on a full-frame camera.

No, this lens is designed exclusively for APS-C sensor cameras with the Fujifilm X mount. Using it on a full-frame camera would result in heavy vignetting (darkened corners) or cropping of the image.

The F1.2 aperture is very wide, allowing more light into the lens. This enables shooting in low-light conditions with faster shutter speeds or lower ISO settings, and it creates a very shallow depth of field for beautiful background blur (bokeh).

Eye AF support ensures that the lens and camera can accurately detect and maintain focus on a subject's eyes, which is crucial for sharp and engaging portraits and for keeping subjects in focus during video recording.

Yes, the quiet STM motor and minimized focus breathing make it very suitable for video recording, ensuring smooth focus transitions and minimal operational noise.

The lens typically includes the lens itself, front and rear lens caps, a lens hood, and possibly a carrying pouch or box, depending on the specific package.

This lens uses a 58mm filter thread size.

Ensure Eye AF is enabled and correctly configured on your camera. Check that the subject is adequately lit and has sufficient contrast. Update your camera's firmware, as lens compatibility is often improved through updates. Clean the lens contacts on both the lens and the camera body.

Confirm that the lens is securely attached to the camera body. Ensure the correct focus mode is selected and that the camera has achieved focus. Check that the aperture is not set too wide (e.g., F1.2) if the depth of field is too shallow for your intended focus point. Clean the lens elements.

Ensure you are using the correct hood for this lens model. Align the bayonet mounts on the hood and lens precisely before twisting. Check for any debris or damage on the mounting surfaces.

Attach the included lens hood to block stray light. Avoid shooting directly into strong light sources unless the flare is desired for creative effect. Ensure lens elements are clean.

The STM motor is designed to be quiet, but some minimal operational sound may be audible, especially in very quiet environments. If the noise is loud or irregular, check for any obstructions or physical damage to the lens. For video, consider using an external microphone placed away from the camera.
