5. Operating the Lens
5.1 Autofocus System
This lens is equipped with an STM (Stepping Motor) and lead screw-type stepping motor, providing fast, smooth, and quiet autofocus performance. It supports advanced autofocus recognition features available on compatible Fuji X-Mount cameras, including eye, animal, and car detection.

5.2 Aperture Control
The F1.8 large aperture allows significant light intake, making the lens excellent for low-light photography. It also enables the creation of soft, pleasing background bokeh, which is particularly effective for portrait photography to isolate the subject.
5.3 Minimum Focusing Distance
The lens offers a minimum focusing distance of 0.4 meters (approximately 1.3 feet). This allows for close-up shots, capturing fine details of subjects like food, crafts, and other everyday scenes.

5.4 Standard Focal Length
With an equivalent full-frame focal length of 53mm, the 35mm focal length on an APS-C sensor closely approximates the human eye's field of view. This makes the lens highly versatile for various shooting scenarios, including street photography, landscapes, portraits, and capturing daily moments.


6. Maintenance
6.1 Cleaning the Lens
- Use a blower brush to remove dust from the lens surface.
- For smudges or fingerprints, use a clean, soft microfiber cloth specifically designed for optical lenses. Apply a small amount of lens cleaning solution to the cloth, not directly to the lens.
- Clean the lens in a circular motion from the center outwards.
- Avoid using abrasive materials or harsh chemicals.
6.2 Storage
- Always attach the front and rear lens caps when the lens is not in use.
- Store the lens in a dry, dust-free environment, preferably in a lens pouch or camera bag.
- If storing for an extended period, consider using a dehumidifier or desiccant to prevent mold growth.
7. Troubleshooting
- Lens not recognized by camera: Ensure the lens is securely mounted and the camera is turned on. Check camera settings for lens detection.
- Autofocus not working: Verify that the camera is set to autofocus mode. Clean the lens contacts on both the lens and camera body. Ensure there is sufficient light for the autofocus system to operate.
- Image quality issues (e.g., soft images): Check that the lens is clean and free from smudges. Ensure proper focus. Consider using a tripod for stability in low light.
- Firmware update failure: Ensure a stable connection between the lens and computer. Do not disconnect the cable during the update process. Refer to the firmware update instructions on the TTArtisan website.
