Conclusion from CameraLabs:
The Canon RF 24-105 f4-7.1 STM is the budget kit zoom the EOS R system has been waiting for. Sure, it may lack the glamour of the brighter aperture and more exotic models, but every system needs a low-cost general-purpose zoom to bundle with the entry-level bodies as a starting point.
Thankfully modern lens design coupled with in-camera corrections actually makes it a lot better than you’d think, especially for the size, weight and money. In my tests it delivered respectable sharpness across the frame, throughout the range and even with the aperture wide-open. By employing a variable aperture that dims to f7.1 at the long-end, Canon’s been able to keep size, weight and cost down, making it a very practical and attainable option, while the reasonably close focusing increases its flexibility further.
If you’re looking for one lens that does it all, you should compare it closely to the RF 24-240 super-zoom and I have a full review of that model too, but as a compact and lightweight starter model, it’s hard to find anything better for the money. Couple either with a fast 35, 50 or 85 for shallow depth-of-field effects and you could be very satisfied.
Canon RF 24-105mm f/4-7.1 IS STM Overview
Sleek and versatile, the Canon RF 24-105mm f/4-7.1 IS STM is a well-rounded zoom covering wide-angle to short telephoto focal lengths to benefit working in a wide variety of conditions. A variable maximum aperture also helps to maintain an impressively compact profile to suit everyday shooting needs. Complementing the flexible design is a unique Center Macro Focus position, which enables working with close-up subjects at a 1:2 maximum magnification ratio, and an Optical Image Stabilizer also helps to achieve sharp imagery by minimizing the appearance of camera shake. Also, an STM motor affords impressively quiet and smooth autofocus performance and full-time manual focus override. Additionally, a configurable Control Ring lets you adjust exposure settings, including ISO, aperture, and exposure compensation, from the lens itself.
