Product Information

Full details

This SIRUI Sniper Series F1.2 APS-C Autofocus Lens Set is ideal for photographers and videographers seeking fast, versatile prime lenses for Sony E-mount APS-C cameras. Its key benefit is the ultra-fast F1.2 aperture, enabling excellent low-light performance and shallow depth of field for subject isolation, all while offering smooth, quiet autofocus. A potential caveat is that it's designed specifically for APS-C sensors, so full-frame users will experience a crop factor.

FAQs

Are these lenses compatible with full-frame Sony cameras?

No, the SIRUI Sniper Series lenses are designed for APS-C format cameras. When used on a full-frame camera, they will result in a significant crop, effectively acting as longer focal lengths than indicated.

What is the main advantage of the F1.2 aperture?

The F1.2 aperture allows for a very shallow depth of field, creating a strong bokeh effect and isolating the subject from the background. It also enables shooting in much lower light conditions without resorting to high ISO settings.

How quiet is the autofocus?

The lenses utilize an STM motor, which is designed for quiet and smooth autofocus operations, making them well-suited for video recording where minimal operational noise is desired.

Can I use a 58mm filter with these lenses?

Yes, all lenses in the set feature a 58mm filter thread, allowing you to use standard 58mm filters for protection or creative purposes.

What focal lengths are included in this set?

The set typically includes prime lenses with focal lengths of 23mm, 33mm, and 56mm, offering versatile options for various shooting scenarios.

How do I update the lens firmware?

Firmware updates are supported via a Type-C port on the lens. You will need to connect the lens (usually via your camera) to a computer and use SIRUI's update software.

Do the lenses have manual focus capabilities?

Yes, the lenses support both autofocus and manual focus adjustments. You can switch between modes via your camera's settings or potentially a switch on the lens itself, depending on camera compatibility.

Troubleshooting

Autofocus is slow or inaccurate.

Ensure Eye-AF or subject tracking is enabled in your camera settings if needed. Check that the camera's autofocus mode is set appropriately for the scene. Update the lens firmware if available. Clean the lens contacts on both the lens and camera body.

Lens won't mount or detach.

Verify that you are using the correct mount (Sony E). Ensure there are no obstructions on the mounting surfaces. Press the lens release button fully when attempting to detach.

Image appears soft or blurry.

Confirm the correct focal length is selected if using a zoom (these are primes). Ensure the lens is securely mounted and the correct aperture is set. Clean the lens elements. Check if the focus mode is set to AF and if the camera is focusing on the intended subject.

Vignetting or light fall-off at the edges.

This is normal at the widest aperture (F1.2). Use the provided lens hood and consider stopping down the aperture slightly (e.g., to F2.0 or F2.8) for reduced vignetting. Most software allows for easy correction of lens-specific vignetting.

Camera does not recognize the lens.

Ensure the lens contacts are clean and free of debris. Try updating the lens firmware. If the issue persists, the lens may need service.

Pros and Cons

Pros

  • Ultra-fast F1.2 aperture for superior low-light and bokeh.
  • Quiet and accurate STM autofocus for video and stills.
  • Excellent subject isolation with shallow depth of field.
  • Consistent physical design for easy switching and gimbal use.
  • Good optical performance with ED and HRI glass.
  • Supports Eye-AF for precise focusing on subjects.

Cons

  • Designed for APS-C sensors, resulting in a crop factor on full-frame cameras.
  • Manual focus might not be as refined as some premium cine lenses.
  • While optically good, might not match the performance of much more expensive prime lenses.
  • The set includes three focal lengths; individual lens purchase might be required for specific needs not covered.

Setup, Compatibility & Care

Compatibility:

This lens set is designed for Sony E-mount mirrorless cameras with APS-C image sensors. Ensure your camera body has the appropriate E-mount.

Setup:

  1. Remove the rear lens cap and your camera's body cap.
  2. Align the mounting index on the lens with the corresponding index on the camera body.
  3. Insert the lens into the mount and rotate it clockwise until it clicks securely into place.
  4. To remove the lens, press and hold the lens release button on the camera body while rotating the lens counter-clockwise.

Care:

  • Cleaning: Use a soft, lint-free microfiber cloth to clean the lens elements. For stubborn smudges, use a lens cleaning solution sparingly on the cloth, not directly on the lens. Avoid abrasive materials or solvents.
  • Storage: Store lenses in their protective cases or a padded camera bag. Use the included lens hoods when not in use to protect the front element. Keep them away from extreme temperatures and humidity.
  • Filter: The lenses feature a 58mm filter thread. Use compatible filters for protection or creative effects. Ensure the filter does not interfere with lens hood placement or autofocus mechanisms.
  • Firmware Updates: Periodically check the SIRUI website for firmware updates. Connect the lens to your camera, then connect the camera to a computer via USB to perform updates using the provided software. Follow the instructions carefully.
