I have a canon rebel t7 right now with a Canon EF lens 50mm 1:1.8 STM and I'm thinking about upgrading to the r7. Would this 50mm EF lens work on the r7 without any added adaptations?</P> Sat, 06 Aug 2022 16:57:24 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/EF-50mm-f-1-8-STM-Compatibility-with-Canon-rebel-t7-R7/m-p/381398#M23343 klhunter33 2022-08-06T16:57:24Z https://community.usa.canon.com/t5/EF-RF-Lenses/EF-50mm-f-1-8-STM-Compatibility-with-Canon-rebel-t7-R7/m-p/381404#M23345 <P>No, you'll need to use an EF to RF adapter for using any EF or EF-S lens with any camera that uses RF-mount lenses such as the EOS R7.</P> Sat, 06 Aug 2022 17:12:57 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/EF-50mm-f-1-8-STM-Compatibility-with-Canon-rebel-t7-R7/m-p/381404#M23345 rs-eos 2022-08-06T17:12:57Z https://community.usa.canon.com/t5/EF-RF-Lenses/EF-50mm-f-1-8-STM-Compatibility-with-Canon-rebel-t7-R7/m-p/381439#M23351 <P>Ricky is correct. &nbsp;You would need to use a mount adapter to use any EF/EF-S lens on an RF mount camera body. &nbsp;No adapter is needed with the Rebel T7 because it uses the EF mount directly.</P> Sat, 06 Aug 2022 23:56:29 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/EF-50mm-f-1-8-STM-Compatibility-with-Canon-rebel-t7-R7/m-p/381439#M23351 Waddizzle 2022-08-06T23:56:29Z
