    Thank, You! It helps me choose my next lense !

    Thank you this is a great and very use­ful review. Even though its not head to head it answers a lot of ques­tions about the rel­a­tive per­for­mance of the lenses.

    In your tests, the EF 24-70 is stopped down. If you stop down the RF 24-105 to f/5.6, the dif­fer­ence con­tin­ues present?

      In the report, I only com­pared the lens­es stopped down at f/11 at 24mm focal length, and the EF 24-70 per­formed bet­ter. The dif­fer­ences decrease in the longer focal length ranges. With­out hav­ing done fur­ther sci­en­tif­ic tests, in my expe­ri­ence I do think that the EF 24-70 f/L II per­forms bet­ter in its range than the RF 24-105, which is also reflect­ed in the list price. Still, the RF 24-105 is not a bad lens, in its price range it is clear­ly a wor­thy buy. Both lens­es are per­fect­ly usable at max­i­mum aperture.

      In any case, I usu­al­ly pre­fer to use the EF 24-70 over the RF 24-105 when I’m trav­el­ing with large pho­to­graph­ic equip­ment. How­ev­er, I still keep the RF and use it when I’m trav­el­ing with lit­tle equip­ment (i.e. cam­era and only one lens), then the extend­ed tele­pho­to range up to 105mm is also helpful.

    So what’s your ver­dict about these two after anoth­er year?
    Did the com­pact­ness of the RF out­shine the size and image qual­i­ty of the EF?
    A used EF 24-70 is a lit­tle cheap­er than a new RF 24-105 and I’m on the brink of choos­ing one of them…

      So, after a good year, I can say that I will keep both lens­es. I take the RF24-105 when I only want to car­ry a small amount of equip­ment, i.e. only the cam­era and one lens. On larg­er shoots, like my recent trip to Kenya, I only pack the EF24-70, because I can use it on both my 5DSR and R5 bod­ies. On safari, my drop-in EF-RF mount adapter worked well. This stayed on the R5 for the entire trip, since I only had EF lens­es with me. Despite the very dusty envi­ron­ment, the clear glass insert did a very good job of pre­vent­ing dust buildup on the sen­sor. If I did­n’t have either of them, the EF 24-70 would prob­a­bly be my first choice because of the afford­able sec­ond-hand price.
