To the best of my knowledge, Canon doesn't make an adapter that will let you use M lenses on an EF mount camera.</P><P>Steve Thomas</P> Sun, 02 Jun 2024 02:33:08 GMT stevet1 2024-06-02T02:33:08Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Need-a-Lens-Adapter-for-T3i/m-p/480621#M116746 <P>I use a Canon T3i camera and recently purchased the 28mm Macro Lens only to discover the two are not comparable. Should I return the lens or is there some kind of adapter I can get to match the smaller lens connector to the larger camera?</P> Sun, 02 Jun 2024 02:01:32 GMT https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Need-a-Lens-Adapter-for-T3i/m-p/480621#M116746 GalacticDonuts 2024-06-02T02:01:32Z https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/Need-a-Lens-Adapter-for-T3i/m-p/480632#M116751 <P>GalaticDonuts,</P><P>If you got the 28mm Ef mount lens, you won't need an adapter, but if you got the EF-M lens, then yes, it won't work.
