Adapting full-frame lens to APS-frame or M4/3 frame camera， it will magnify the focal length by 1.6 on Canon, 1.5 on Nikon and Sony，2.0 on M4/3 camera

Canon STM series lenses don't work with our Canon EOS (EF / EF-S) D/SLR Lens adapters.
STM lens (such as EF 50mm f/1.8 STM, EF 18-135 IS STM) requires to be powered to drive the motor to focus, so cannot achieve focus with manual adapters.
Manual adapters have no electronic contacts, which therefore don't support auto-focus or aperture control. K&F Concept lens mount adapters are all manual ones.
Please figure out the mount of your camera and lens in case of buying the wrong adapter.
