Canon announced a slew of new gear today including the EOS R5 and EOS R6full-frame mirrorless cameras. Along with the bodies, Canon has released new lenses for the RF mount. Among them are a new 85mm F2 Macro IS STM, a RF 100-500mm F4.5-7.1 L IS USM, a RF 600mm F11 IS STM, and a RF 800mm F11 IS STM as well as a 1.4x and 2x teleconverter

85mm


RF 85mm F2 Macro IS STM

Canon already offers two different 85mm for RF mount. The RF 85mm F1.2 L USM and RF 85mm F1.2 L USM DS priced above $2,500. The difference between the two is the "DS" feature which stands for defocus smoothing. The latest 85mm F2 Marco IS STM is a mid-telephoto lens ideal for still portraits or videography. 

It has a fast F2 aperture and 9 blade circular design, and with a minimum focusing distance of 1.14 feet (0.35m), it will be easy to get close to a subject. Optically, it's constructed from 12 elements in 11 groups with one UD (Ultra Low Dispersion) lens and a maximum magnification of 5x. 

The lens is equipped with Canon's optical image stabilization (IS) with up to 5 stops of shake correction. The hybrid IS compensates for angular and shift camera shake during macro shooting. When paired with the EOS R5 or EOS R5, which has in-body image stabilization, the combined IBIS and IS will provide up to 8 stops of correction. 

Similar to other RF lenses, the 85mm F2 also has a control ring that can be used to direct setting changes. It weighs approximately 1.10 lbs (500g). It's availability is scheduled for October 2020 for around $599.

Rf100-500mm

RF 100-500mm F4.5-7.1 L IS USM

The super-telephoto lens isn't simply a rehoused EF 100-400mm F4.5-5.6 IS II USM lens. Canon built the lens from the ground up while including the versatility and high performance L-series shooters are familiar with but in a RF lens. 

The long-reaching lens is designed from 20 elements in 14 groups with one Super UD and six UD elements. It has a minimum focusing distance of 2.95 ft at 100mm and its 9 blade aperture design will provide the familiar bokeh Canon shooters are used to. 

Canon also improved the dust and weather sealing of the external zoom lens, and it's equipped with two Nano USM motors for floating focus control that is quick to respond. Then lens is lighter too, about 200 grams lighter than the EF 100-400mm at 3.0 lbs (1,365g) without a tripod mount. 

The RF100-500mm F4.5-7.1 L IS USM is set to be available September 2020 with an estimated price of $2,699.

600mm

RF 600mm F11 IS STM

This is Canon's first compact and lightweight 600mm telephoto RF lens. It features a retracting locking lens barrel design, gapless double-layer diffractive optics to reduce chromatic abberation, and a fixed F11 aperture.

The lens also has Canon's optical image stabilization (IS) with up to 5 stops of shake correction. The lead screw-type STM enables for smooth autofocusing for video shooting and stills, while the control ring allows you to direct setting changes. 

Constructed from 10 elements in 7 groups it has a special DO (gapless double-layer diffractive optics) lens and does not have an aperture blade design. The lens has a front filter size of 82mm and weighs 2.05 lbs (930g). 

The RF600mm F11 IS STM is expected to arrive July 2020 with a price tag around $699 

800mm

RF 800mm F11 IS STM

Like it's 600mm sibling, the RG 800mm F11 IS STM, is another Canon RF lens first. It features the same retracting locking lens barrel design, fixed F11 aperture, and the gapless double-layer diffractive optics to reduce chromatic abberation. 

With extra 200mm distance, there isn't a loss in terms of image quality, but image stabilization is reduced to 4 stops instead of 5. The lens is also without an aperture blade design and is constructed out of 11 elements in 8 groups. The 800mm is very portable coming in around 14" in length while the 600mm is even less at about 10" in length. The 800mm F11 IS STM weighs approximately 2.77 lbs. (1260g). 

The price for this lens will be $899 and will arrive in July 2020. 

Rftele

RF 1.4x and 2.0x Teleconverters

Besides the lenses, two teleconverters are available for RF glass, a 1.4x and 2.0x. The 1.4x is made from 7 elements in 4 groups weighing 225g, while the 2.0 is comprised of 9 elements in 5 groups weighing 340g. Each teleconverter is compatible with the RF 100-500mm F4-7.1L IS USM, RF 600mm F11 IS STM, and the RF 800mm F11 IS STM.
