Ch LAST DAY to win a Canon EOS R: http://freesdp.comCanon 24-105mm f/4R ($1,099): http://sdp.io/C105RCanon EOS R ($2,300): http://sdp.io/RWe've now taken over 1 The Canon RF 24-50mm f/4.5-6.3 lens is priced at £379. It seems to be unique in the Canon range, the nearest lenses being not the same specification or very expensive L series optics. Overall Enter the equivalent lenses in each of their respective mirrorless systems, the Canon RF 24-240mm F4-6.3 IS USM and Nikon Z 24-200mm f/4-6.3 VR. But which one does a better job of balancing composition flexibility, portability and image quality. I bought two R5 bodies, one for a 24-105 f/4 and the other for a 70-200 f/2.8 or 100-500 f/4.5-7.1 so I wouldn't have to change lenses all the time and risk dropping one, and slowing everything down and taking the fun out of it. Now, except for the most hard core pixel peeping sessions, I'm wondering if that was worth it. The Canon RF 24- 105mm F4 L IS USM is by far the most beefy kit lens canon has ever made. The tech that has gone into it definitly justifies it cost. It is a CDcH.
