Photography Blog posted their Canon RF 70-200mm f/2.8L IS review, and they seem to be pretty fond of this lens.
They gave the Canon RF 70-200mm f/2.8L IS 5/5 stars and an “Essential” rating. Have a look at the review conclusion:
[the RF 70-200mm f/2.8L IS] offers fantastic sharpness and image quality throughout the zoom range, great build quality, and an outstanding feature-set and performance.
Image quality is simply amazing. It’s outstanding at almost every focal length, with epic levels of sharpness virtually throughout the aperture range.
Chromatic aberrations are almost non-existent and flare is only ever an issue when shooting directly into the sun or if you choose not to use the large lens hood.
The only optical issue of note is a slight drop-off in sharpness when shooting wide-open at f/2.8 at the 200mm focal length – otherwise this lens is a stellar performer.
Auto-focusing proved to be very quick, accurate and reliable on the Canon EOS RP mirrorless camera that we tested the lens with, while manual focus over-ride is a great feature, as is the effective built-in optical image stabilisation system that’s worth up to 5 stops.Read the Canon RF 70-200mm f/2.8L IS review at Photography Blog
Guess the only drawback of this stellar performer is the price, $2,699.
