Photography Blog posted a comprehensive review of the new Canon RF 24-105mm f/4L IS lens for EOS R system.
The Canon RF 24-105mm f/4L IS appears to be another optical masterpiece by Canon.
From the conclusion:
The Canon RF 24-105mm f/4L IS is an excellent standard zoom lens that optically is a step above the equivalent DSLR variant, the Canon EF 24-105mm f/4L IS II, which incidentally is one of Canon’s most popular lenses.
The RF 24-105mm offers a very versatile focal range whilst being tack-sharp from 24mm to 85mm, both in the centre and at the edges of the frame. Sharpness at the far end of the telephoto range isn’t quite as good when shooting wide-open at f/4, but you only have to stop down to f/5.6 to get more than acceptable results. Overall the Canon RF 24-105mm f/4L IS delivers excellent sharpness across the frame at most apertures. Vignetting at wide-open apertures and some barrel distortion at 24mm are the only other real optical issues of note.
Build quality is excellent, certainly up to the usual L-lens standard, with the built-in weather-proofing offering peace of mind in more inclement conditions.
