mirrorlesscomparison.com hat einen ausführlichen Vergleich der EF- und RF-Ausgabe der beliebten 24-105er Klasse veröffentlicht:


The differences aren’t as significant as we had anticipated however, and let’s not forget that many other aspects are almost identical, such as the stabilisation and autofocus performance and perhaps most importantly, the price.

For these reasons, we feel that if, as a former or current Canon user, you already own the EF version of the 24-105mm, it makes sense to purchase the EF-EOS R adapter (which costs around $99 at the time of writing) and continue using it on the EOS R, especially if you plan to keep your Canon DSLR.
