Lightdow 85mm F1.8 Portrait Lens - Canon EF/EF-S Mount

No, the Lightdow 85mm F1.8 is a fully manual focus lens. You will need to adjust focus using the manual focus ring on the lens.

The f/1.8 aperture is very wide, allowing you to shoot in low light and create a shallow depth of field, which results in a blurred background (bokeh) that makes your subject stand out.

This lens is designed for Canon EF/EF-S DSLR mounts. To use it on an EOS R series camera, you will need an appropriate EF-EOS R mount adapter. Performance may vary.

This is expected behavior for manual lenses without electronic contacts. The camera cannot read the aperture settings. You will need to set your exposure manually using your camera's light meter or in Manual (M) mode.

Yes, the smooth manual focus ring can be beneficial for video recording, allowing for precise focus pulls. The bokeh also adds a cinematic quality to footage.

EF lenses can be used on both full-frame (EF) and APS-C (EF-S) Canon DSLRs. EF-S lenses are designed only for APS-C Canon DSLRs. This 85mm lens is compatible with both types of Canon DSLRs.

Use a soft lens brush to remove dust, followed by a lens cleaning solution applied to a microfiber lens cloth. Gently wipe the lens in a circular motion from the center outwards.

Ensure your camera is set to Manual (M) shooting mode. You may also need to enable "Release shutter without lens" in your camera's custom settings.

This is normal for manual lenses without electronic communication. Focus and exposure will need to be managed manually or with your camera's meter in Manual mode.

Practice using the manual focus ring. Use your camera's live view zoomed in or focus peaking (if available) to aid in precise focusing, especially at wider apertures.

Remove the lens and reattach it, ensuring it clicks securely into place. Check for any debris on the mounting surfaces.
