Q: 9. Will this work with Canon RP?

A: Not directly, no. The Canon EF-S 17-85mm f/4-5.6 IS USM Lens is designed for use on Canon DSLR cameras that use the EF-S lens mount. The Canon EOS RP Mirrorless Digital Camera uses the Canon RF lens mount. As such, you would need a lens mount adapter such as the Canon Mount Adapter EF-EOS R, B&H # CAMAEFRF, or the Vello Auto Lens Adapter for Canon EF/EF-S Lens to Canon RF-Mount Camera, B&H # VELAECRCEF, to use the above lens on the EOS RP. Do note that the Canon EF-S 17-85mm f/4-5.6 IS USM Lens is designed for cameras that use the smaller APS-C sensor, while the Canon EOS RP Mirrorless Digital Camera uses a full-frame sensor. As such, you would have to use the [Cropping/Aspect Ratio] under the Shooting Menu in the camera's menu ​set to the 1.6x crop mode to use the lens on your camera. If you use the full-frame setting, you will get a large, dark vignette around the edge of the frame where the lens' smaller imaging circle blocks light from illuminating the pixels on the outer edge of the larger full-frame sensor.

Q: 10. How is this lens compared to the Canon EF 16-35mm f/4L IS USM Lens? Also considering that it is cheaper?
