The Canon RF 24-105mm F2.8L IS USM Z seems like a logical introduction from Canon but I’m yet to be convinced by the implementation of the power zoom functionality. Keeping it separate from the lens in the form of an adapter likely reduces the price, size and weight of this and future lenses in the RF Hybrid line, but it would be slicker to And in achieving this size, Canon did not increase the diameter of the RF version. Just like the EF version, this newer mirrorless version also has the same 3.29” (or 83.5mm) exterior diameter, sporting the same 77mm filter thread. To some, a fraction of an inch may not seem like much of a reason to consider the RF 24-105. Canon RF 24-105 F4L IS USM FREE SHIPPING FOR PURCHASES OVER $200 WITHIN SINGAPORE ONLY.
