SHAH ALAM, 28 February 2022 - Canon has announced the launch of two new L-series super telephoto prime lenses: the RF800mm f/5.6L IS USM and the RF1200mm f/8L IS USM. Canon is a rare manufacturer of 1200mm lenses, of which very few are in existence. Supporting autofocusing and image stabilisation even with extenders, both lenses achieve their impressive reach while weighing just over 3kg. While, the RF800mm f/5.6L IS USM and RF1200mm f/8L IS USM are significantly smaller and lighter than their EF lens counterparts, they maintain the signature superior image quality of L series lenses. With these new lenses, Canon’s RF lens lineup now provides the most comprehensive focal range for users, from an ultra-wide-angle 14mm up to an unparalleled super telephoto 2400mm.

“The launch of these two lenses is aligned with our commitment to enhance the EOS R ecosystem, and to meet the different needs of photographers across various skill levels and requirements. Both the RF800mm f/5.6L IS USM and RF1200mm f/8L IS USM lenses utilise the RF mount, which allows photographers to take advantage of its portability. We look forward to seeing these lenses help photographers discover new realms of photography and produce better results, even in advanced applications such as wildlife, astrophotography, sports photography, and surveillance,” said Hunter Zhang, Director of Imaging Communications Business Division at Canon Marketing Malaysia.

Behemoths Downscaled: Size and Weight Reductions Up To 80%

The RF1200mm f/8L IS USM cuts 13kg in weight (approx. 80%) and 299mm (approx. 35%) in length from its 16.5kg predecessor, the EF1200mm f/5.6L USM, even with the inclusion of an in-lens Optical Image Stabilizer (Optical IS). Meanwhile, the RF800mm f/5.6L IS USM achieves a 1.36kg (approx. 30%) weight reduction over its predecessor, the EF800mm f/5.6L IS USM.

The significant downscaling was achieved by adding magnification optics towards the back of the optical designs of the EF400mm f/2.8L IS III USM and EF600mm f/4L IS III USM, two lenses which had also achieved significant size and weight reduction while maintaining high optical performance. 

Both lenses feature a highly durable vibration and shock-proof structure, with dust- and drip-resistant weather sealing to prevent moisture from entering. 

Reach Further with Extenders, Bolstered by AF Support 

Both the RF800mm f/5.6L IS USM and the RF1200mm f/8L IS USM are compatible with the Extender RF 1.4x and the Extender RF 2x. The focal lengths with the extenders are as follows:

It is hard to find other camera systems which offer the ability to reach focal lengths of more than 1600mm on an autofocus-capable super telephoto lens and extender.

When the lenses and extenders are combined with the EOS R system’s Dual Pixel CMOS AF, AF is possible over a wide coverage area even beyond maximum aperture f/8—up to 100% coverage on the EOS R3, EOS R5, and EOS R6. With this, user can enjoy the benefits of AF, such as Animal Detection AF, in more situations than possible on a DSLR camera. The lenses also support continuous shooting of up to 30 fps (electronic shutter) when paired with a high-performance camera like the EOS R3.

Incorporating Canon’s Proprietary Technology for Superior Image Quality

Leveraging on the flexibility of the RF mount, the RF800mm f/5.6L IS USM and the RF1200mm f/8L IS USM lens configurations are optimised to achieve the signature outstanding 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 to combat the chromatic aberration that super telephoto lenses are particularly susceptible to, achieving crisp, clear images all the way to the edges of the frame. 

Enhanced Image Stabilisation for Super Telephoto Shooting

Both lenses are equipped with the in-lens Optical IS image stabilisation system, which significantly corrects the camera shake that becomes particularly visible at ultra-long focal lengths. On the RF800mm f/5.6L IS USM, the equivalent of up to 4.5 shutter speed stops of image stabilisation is achieved (Predecessor: 4 stops); on the RF1200mm f/8L IS USM, the image stabilisation effect is up to 4 shutter speed stops equivalent 3 (Predecessor: no IS). 

Unprecedented Portability Expands Application Usage 

Professional super telephoto lenses are traditionally associated with bulky heft. The unprecedented portability achieved by the RF800mm f/5.6L IS USM and the RF1200mm f/8L IS USM will make them more appealing to new markets and new applications, especially when combined with the ever-increasing capabilities of the EOS R mirrorless camera system.
