I am Looking for AF Option for the Komodo. The question is: shall i purchase Can EF-lenses such as the 14 mm2.8 or the 11-24 mm OR the new RF lenses such the 15-35 mm. At the moment Autofucus , I think only works propery with the recommended EF lenses. But the RF -lenses are low weigth and very compact. So what to do?
