I continue to be impressed with both the resolution and clarity obtained using Canon's RF 24-105 F4L attached to an R6 body. This portrait made recently during a gathering of Audubon members celebrating ongoing efforts to save the Wood Storks at Silver Bluff's Kathwood Stork ponds, where the wood storks continue to thrive and multiply. 105mm 1/200 @ F6.3 ISO 500 . The R6's eye controlled focus works great and the F4L 24-105 is a very capable lens, much sharper than the EF version, IMO.
