Tamron 11-20mm f/2.8 Di III-A RXD Lens - Sony E-Mount

This lens is exclusively designed for Sony E-mount APS-C mirrorless cameras, such as the Sony a6000 series, a5000 series, and ZV-E10.

Yes, you can physically mount this lens on a full-frame Sony E-mount camera (e.g., Sony a7 or a9 series). However, it will automatically operate in APS-C crop mode, which means your images will be cropped, and the resolution will be reduced to match the APS-C sensor area.

The f/2.8 constant aperture allows for excellent low-light performance, enabling you to shoot in dimmer conditions without excessively high ISO. It also provides a shallower depth of field and beautiful bokeh, which is unique for an ultra-wide-angle lens, offering more creative control over your images.

Absolutely. Its compact and lightweight design makes it ideal for use on gimbals and for handheld video. The RXD stepping motor ensures fast, precise, and notably quiet autofocus, which is crucial for capturing video without distracting motor noise.

The Tamron 11-20mm f/2.8 Di III-A RXD uses a 67mm filter thread. This common size allows for easy sharing of filters (e.g., UV, CPL, ND) with other Tamron lenses that also feature this filter diameter.

Yes, this lens offers remarkable close-up capabilities with a Minimum Object Distance (MOD) of just 0.15 meters (5.9 inches) at the 11mm wide end. This allows for unique wide-angle macro shots, emphasizing foreground subjects while still showing the expansive background.

While designed for APS-C, this lens offers an equivalent focal range of approximately 16.5-30mm on a full-frame camera. Its primary advantage over full-frame counterparts is its significantly smaller size, lighter weight, and often lower cost, making it an excellent portable option for APS-C users without sacrificing a fast aperture.

1. Ensure your camera's autofocus mode is set appropriately (e.g., AF-C for continuous, AF-S for single shot).
2. Clean the lens and camera contacts with a clean, dry microfiber cloth. Dirty contacts can interfere with communication.
3. Ensure there is adequate light on your subject; autofocus systems perform best in good lighting conditions.
4. Check your camera's firmware. Ensure both the camera and lens (if applicable via camera body) have the latest firmware installed.

1. Verify your focus point. Make sure the lens is focusing on your intended subject.
2. Check your camera's shutter speed. A slow shutter speed can lead to motion blur, especially with wide-angle lenses if not held steady.
3. Ensure the lens elements are clean from dust, smudges, or moisture.
4. If using a tripod, ensure it's stable and there's no vibration. If shooting handheld, consider increasing shutter speed or using a higher ISO if necessary.

1. Turn off your camera before attaching or detaching the lens. Ensure the lens is securely mounted with an audible click.
2. Remove the lens and reattach it, ensuring good contact between the lens and camera mounting points.
3. Clean the electrical contacts on both the lens and the camera body carefully.
4. Check your camera's settings to ensure it's not set to 'Shoot without lens' if it has such an option, although this is usually for manual lenses.
5. If the issue persists, update your camera's firmware to the latest version. This sometimes resolves compatibility issues.
