Canon RF 100-300mm F2.8L IS USM Lens is coming. According to the digicame-info, this new lens will cost $9,499! The lens hood is ET-124 for $650 and the lens cap is E-112 for just $25.
It seems that Canon will soon release a large-aperture telephoto zoom through F2.8. There are 120-300mm F2.8 lenses for SLRs from Sigma and Nikon, but this kind of zoom is the first for Canon.
We are a little curious as to whether Canon RF 300mm F2.8L, which was previously rumored to appear, was about this lens, or whether it will appear separately from this lens.
