Whether you travel near or far, the EOS RP helps you capture your world with the quality, control and ease you crave.- 26.2 MP CMOS Sensor- Full-Frame Mirrorless Format- 5 fps Continuous Shooting- 100-40,000 ISO Sensitivity- 4K UHD 3840 x 2160 at 23.98fps Video- Vari-Angle TouchscreenÂż- Kit includes Canon EOS RP camera & 24-105 STM lens.The RF 24-105 is a USM type lens. There are two different RF 24-105 lenses. I think you are talking about the RF 24-105 F4L IS, which is USM. The OP was asking about the RF 24-105 F4-7.1 IS STM. Maybe some other posters were also confused, and were talking about the L version, instead of the STM version? It also supports the faster ES frame rates.
In re: the RF 24-105 f4.0-7.1 STM, yes there is distortion and vignetting at 24mm. Vignetting is gone at 28mm. Both vignetting and distortion are corrected by the camera and can be adjusted further in either Lightroom or Canon DPP. Post processed, the images are fine. Here is one I shot with the RF 24-105 f4.0-7.1 STM @ 24mm at a local airport.
Canon EF 24-105mm f/3.5-5.6 IS STM review – Resolution. Our lab test demonstrates that the EF 24-105mm f/3.5-5.6 IS STM is sharpest when used at the wide end of the focal range, but conversely this is also the point at which there is the greatest fall-off from edge to centre – until f/11, where the best overall sharpness occurs.
Here is a Canon RF 24-105mm f/4-7.1 IS STM review, a more budget-oriented lens option for the EOS R full frame mirrorless camera system. Christopher Frost Photography posted a 12min video where he discusses the features and performance of the Canon RF 24-105mm f/4-7.1 IS STM:
