Product Information

Full details

This SIRUI Nightwalker 2-lens set, featuring 16mm and 75mm focal lengths, is designed for S35/APS-C camera users seeking exceptional low-light performance and shallow depth of field for professional video productions. Its key benefit lies in the fast T1.2 aperture, enabling clear shots in minimal light with beautiful bokeh, while a potential caveat for some users might be its specific S35 coverage, requiring awareness for full-frame shooters. The set offers consistent optical characteristics, minimal focus breathing, and unified physical design for seamless lens changes.

FAQs

What camera sensor size are these lenses designed for?

These lenses are designed for Super35/APS-C sensor sizes. They will cover these formats fully but will vignette significantly on larger, full-frame sensors.

Are these lenses suitable for photography as well as videography?

Yes, while optimized for video with features like minimal focus breathing and a stepless aperture, they also perform very well for still photography, especially in low light.

What is the equivalent full-frame focal length for these lenses?

The 16mm lens provides a field of view roughly equivalent to a 24mm lens on a full-frame camera, and the 75mm lens is equivalent to approximately 113mm on a full-frame camera.

Do the lenses have image stabilization?

No, these lenses do not have built-in image stabilization. Stabilization would rely on the camera body's internal stabilization system (if available) or external stabilization methods.

What is the filter thread size?

Both the 16mm and 75mm lenses feature a unified 67mm filter thread (M67*0.75).

How do I achieve a smooth bokeh effect?

The fast T1.2 aperture, combined with a shallow depth of field, naturally creates a smooth bokeh effect. To maximize this, use a wider aperture (lower T-stop number) and position your subject closer to the camera while ensuring the background is further away.

Can I use these lenses with a full-frame camera?

You can mount them on a full-frame camera, but they are designed for S35 coverage, so you will experience heavy vignetting or must crop the image to the S35 format.

Troubleshooting

Lens does not mount to the camera.

Verify that the lens mount (e.g., MFT) matches your camera body's mount. Ensure no obstructions or damage are present on either the lens mount or the camera mount. Check for a small locking lever or button on the camera body that may need to be released.

Image appears soft or blurry.

Confirm the lens is focused correctly on the subject. Check that the aperture is not set too wide if excessive softness is observed at T1.2 (though sharpness is generally maintained). Ensure lens caps and protective filters are removed.

Focus ring is stiff or loose.

If stiff, dust or debris may be interfering. If excessively loose, it may indicate internal wear. Contact customer support for inspection or repair.

Aperture ring is difficult to turn.

Ensure the aperture setting is not at its extreme limit. If consistently stiff, it may require professional servicing.

Pros and Cons

Pros

Excellent low-light capability due to the T1.2 aperture.
Produces beautiful, creamy bokeh for subject separation.
Consistent design across lenses simplifies workflow.
Minimal focus breathing enhances cinematic quality.
Sharpness is maintained even at the widest apertures.
Controlled distortion provides natural-looking images.

Cons

Covers S35/APS-C sensors, not full-frame without vignetting.
The 75mm focal length might be too long for some indoor or wide shots.
Requires specific mounts; check compatibility before purchase.
Minimum focus distance of 0.7m on the 75mm may limit close-up work.

Setup, Compatibility & Care

Setup: The lenses are designed for direct mounting onto cameras with compatible mounts (Micro Four Thirds in this specific set, with other mounts available separately). Ensure your camera body is clean before attaching the lens. Mount the lens by aligning the red dot on the lens with the corresponding mark on the camera mount, then twist the lens until it clicks into place.

Compatibility: This particular set is for Micro Four Thirds (MFT) mount cameras. Ensure your camera sensor format is Super35/APS-C or smaller to utilize the full image circle without significant vignetting. For full-frame cameras, expect the image to be cropped to the S35 format.

Care: To maintain optical quality and mechanical function:

Cleaning: Use a soft lens brush or a can of compressed air to remove loose dust. For smudges, use a microfiber cloth lightly dampened with lens cleaning solution. Never spray solution directly onto the lens.
Storage: Store lenses in their protective cases in a cool, dry environment. Avoid extreme temperatures and humidity.
Handling: Always handle lenses by the body, avoiding direct contact with the glass elements. Use lens caps when not in use to protect the front and rear elements.
