Purpose and Audience

The lightdow KD-8518C is an 85mm f1.8 manual-focus prime lens built for Canon EF and EF-S DSLR bodies. It suits portrait photographers who want precise focus control and a wide maximum aperture for shallow depth of field.

Installation and Common Issues

Mount the lens, then immediately switch the camera to full manual (M) mode because the lens has no electronic contacts. If a "no lens" error appears, enable the "Release shutter without lens" option in the camera menu to allow shooting.

Compatibility Check

Verify that your Canon DSLR uses the EF or EF-S mount; the long list of supported models includes Rebel, xxD, 5D, 6D, 7D and 1D series bodies. No electronic communication means autofocus and aperture control from the camera are unavailable.

Questions about this item

How can I confirm the lens is working after mounting it on my Canon EOS 90D?

Set the camera to Manual (M) mode and enable "Release shutter without lens" in the menu. Turn the 85 mm focus ring; the viewfinder image should sharpen smoothly at the f1.8 aperture.

What comes in the box and what must I buy separately?

The box contains the EF-mount 85mm f1.8 lens with front and rear caps. You will need to purchase 72 mm filters, a lens hood and a cleaning cloth separately.

Which version of this lens should I choose for portrait work on a Canon 5D Mark IV?

The KD-8518C is a single 85 mm f1.8 manual-focus prime with 6 elements in 6 groups and 6 rounded aperture blades, designed for EF-mount full-frame and APS-C bodies.
