The Canon RF 24-240mm F4-6.3 IS USM covers a bigger zoom range than any other lens for the system, but it makes some sacrifices to get there. See It Read Our Canon RF 24-105mm F4-7.1 IS STM At the time of writing, Canon has only made two native lenses for the EOS R10 and its EOS R7 sibling: the RF-S 18-45mm f/4.5-6.3 IS STM and RF-S 18-150mm f/3.5-6.3 IS STM zoom. Matching the diminutive dimensions of Canon crop sensor bodies such as the new R100, the new Canon RF-S 55-210mm f/5-7.1 IS STM lens is also incredibly light and compact. The Canon RF-S 55-210mm f/5-7.1 IS STM offers APS-C photographers an equivalent zoom from 88-336mm, while the RF 24-50mm f/4.5-6.3 IS STM is a compact standard zoom lens for full-frame mirrorless R7 + RF-S 18-150mm f/3.5-6.3 kit; R7, and use half of the saved $ to pick up a used RF 24-105mm f/4-7.1; I do not own any RF lenses or good EF lenses, and just need an entry-level all-round lens to start with (probably getting RF 100-400 and RF 600 in the future). item 6 Canon RF 24-105mm F/4-7.1 IS STM Lens For Canon R Type Cameras Canon RF 24-105mm F/4-7.1 IS STM Lens For Canon R Type Cameras. $267.99 Read full review.
