This is an RF lens, although it's listed under the EF category because there isn't an RF lens category. It's a beautiful lens, purchased as part of an R6 kit and only used for a test run where about 20 photos were taken. I've been using EF lenses I already owned with an adapter, so I only used this lens once for the test run and then stored it in a dehumidified storage box. Shipping will be done using the original Canon premium maintenance box and packing materials. I'm not considering price reductions at this time. Thank you!
