Canon has filed a patent utility for 3 lenses, together with this 200-800mm telephoto zoom lens.
Whereas patents are usually not assured to lead to precise merchandise for patrons to purchase, some new Canon lens patents are nonetheless certain to excite photographers, particularly wildlife and sports activities photographers.
As AsobiNet studies, Canon has filed patents in Japan for 3 new zoom lens designs, two of that are full-frame lenses.
Maybe probably the most thrilling of the bunch is a patent for a 200-800mm f/5.8-9.2, presumably equating nominally to f/5.6-9. The patent utility showcases an optical design that contains about 20 parts, together with a picture stabilization (IS) group. The applying additionally describes a “compact and light-weight zoom lens,” which sounds ultimate for handholding.
A 200-800mm telephoto zoom lens can be the primary of its variety. It could even be the second 4x telephoto zoom in Canon’s RF lens lineup, becoming a member of the favored Canon RF 100-400mm f/5.6-8 IS USM lens, which at simply $649 is a wonderful worth possibility for enthusiastic wildlife and sports activities photographers on a tighter finances.
Canon’s present longest RF lens is the RF 1200mm f/8L IS USM, however its eye-watering $19,999 price ticket places it out of attain for almost each photographer. Canon’s RF 800mm f/11 IS STM lens is rather more accessible, due to its $999 value, however it’s restricted by its fastened focal size and sluggish f/11 aperture.
The 200-800mm focal size can be paying homage to an outdated SLR lens, the Sigma 300-800mm f/5.6 EX DG APO IF HSM. In fact, a major distinction between the Sigma zoom and the patented Canon lens comes all the way down to the aperture.
The patented 200-800mm zoom lens might break up the distinction between the 2 extremes of a sluggish and reasonably priced telephoto lens and a quick, hefty, and costly skilled lens.
Alongside the 200-800mm full-frame zoom lens, Canon has additionally filed a patent utility for a 100-600mm f/5.8-9.2 telephoto zoom lens. With a bit much less attain than a 200-800mm lens, the 6x zoom optic also needs to function a compact, lighter design.
Just like the 200-800mm patent utility, the included determine for the 100-600mm lens exhibits an IS group. Just like the 200-800mm focal size, a 100-600mm lens would even be new. Though comparable, the Sigma 150-600mm f/5-6.3 DG OS HSM Sport lens and Canon RF 100-500mm f/4.5-7.1 L IS USM are barely totally different and don’t ship as a lot focal size versatility as Canon’s proposed new zoom.

Rounding out the possible lenses is an APS-C zoom with a 20-150mm focal and f/4.1-8.1 aperture vary. An APS-C lens like this could provide an equal focal size of about 32-240mm, which might be a helpful all-in-one journey zoom lens.
Canon Rumors notes that this APS-C lens “wouldn’t be used on the RF mount and even the EOS-M mount,” so it stays unclear what the lens can be for. Canon Rumors speculates that it could possibly be for a PowerShot digicam, though the PowerShot line has not obtained a lot consideration from Canon in recent times.
To reiterate, whereas these patented optics are attention-grabbing and probably very thrilling to Canon photographers, there are numerous examples of patented lenses remaining within the annals of patent filings ceaselessly. Simply because Canon has filed patent functions doesn’t imply that the corporate intends to provide and promote any of the proposed lenses.
With that mentioned, it’s also value contemplating how mirrorless cameras and advances in optical applied sciences have enabled lens designers to develop never-before-seen focal size ranges. Canon itself has already demonstrated this with the RF 100-500mm lens, which is new to Canon’s EOS R mirrorless platform.
Likewise, Nikon has proven that the Z mount allows innovation via its new Z 180-600mm f/5.6-6.3 VR lens and its outstanding Nikkor Z 58mm f/0.95 S Noct prime.
