Behemoths Downscaled: Up to 80% reduction in size and weight
The RF1200mm F8L IS USM has been reduced to 13 kg in length from its previous version (16.5 kg) EF1200mm F5.6L USM. It has been reduced by 299mm (about 35 percent). This is also done when an in-lens is included and also an optical image stabilizer (optical IS). Meanwhile, the RF800mm F5.6L IS USM weighs in at 1.36kg compared to its older EF800mm F5.6L IS USM.
Magnification optics have been added to the back of the optical designs of the EF400mm F2.8L IS III USM and EF600mm F4L IS III USM. These two lenses that have reduced size and weight while still maintaining high optical performance. Both the lenses are equipped with a highly durable vibration and shock-proof structure that is dust and drip resistant to prevent moisture loss.
The RF800mm F5.6L IS USM and the RF1200mm F8L IS USM are both compatible with the Extender RF 1.4x and Extender RF 2x. The focal length with extenders is as follows:
Extender RF 1.4x
Extender RF 2x
RF800mm F5.6L IS USM
RF1200mm F8L IS USM
It’s hard to find other camera systems that offer autofocus-enabled super telephoto lenses and extenders up to focal lengths of over 1600mm.
When the lens and extender are combined with the EOS R system’s Dual Pixel CMOS AF, the AF extends over a wide coverage area. Users can take advantage of the benefits of AF. This includes Animal Detection AF etc.
Incorporating Canon’s proprietary technology for superior image quality
Taking advantage of the flexibility of the RF mount, the RF800mm F5.6L IS USM and RF1200mm F8L IS USM lens configurations are optimized to achieve excellent L-lens image quality within a smaller, lighter lens body. This includes the use of fluorite, Super UD (Ultra Low Dispersion) and UD lens elements that Super Telephoto lenses are particularly susceptible to, achieving crisp, clear images all the way to the edges of the frame.
