On this patent utility (2024-101302), Canon discusses some distinctive telephoto lenses. A lot of the lenses in right here could be eye-watering priced, so maintain onto your bank cards. Simply in case.

The first goal of this patent utility is to discover designs which might be gotten smaller and weight for the given giant aperture.

In response to the current invention, it’s attainable to supply a zoom lens that’s small in measurement and has a big aperture, but has excessive optical efficiency.

It ought to be observed that regardless that the again focus distance is pretty relaxed, that is almost definitely in order that these lenses can assist teleconverters.

Canon RF 400-600mm F2.8-4.0

That is an internal zoom design exhibiting a variable aperture from F2.8 to F4.0, which in fact permits it to be a smaller measurement and weight than a relentless aperture F2.8 could be, whereas nonetheless providing you with 600mm of telephoto functionality. I might see this lens coming to Canon if it wasn’t for the following 300-600mm F2.8-4L embodiment.

Canon RF 300-600mm F2.8-4.5L

I might definitely see Canon making this focal size and aperture as a pleasant continuation from the Canon RF 100-300mm f/2.8L IS USM. Nevertheless, there’s one other embodiment that I feel is slightly higher close to the underside of this text.

Canon RF 70-300mm F4L

That is an fascinating lens, that expands on the everyday 70-200 F4L vary and provides it an additional 100mm in focal size. If this was an affordable worth, given the scale of solely 250mm in your equipment bag, and teleconverter functionality – Canon would have a really tough time making sufficient of those. Take into account that this lens is barely round 100mm longer than the legendary Canon EF 70-200mm f/4L IS USM. There may be nonetheless a number of “area” at 70mm within the optical design, so it is totally attainable that mechanically, Canon might shrink this lens down even additional for storage, and have a twist “unlock” to 70mm.

Canon RF 300-600mm F2.8-4.5L

Of the 2 300-600mm designs I like this one a bit extra as a result of the again focus distance is slightly longer. That permits for extra space for a teleconverter meeting.

Canon RF 100-300mm F4L

If the Canon RF 100-300mm f/2.8L is just too huge, heavy, or costly this may very well be a compelling possibility.

Whereas we’re by no means certain which patent purposes will make it into manufacturing there may be some variability between once we see it and if a product goes to seem. Nevertheless, most instances, until there are critical delays we have a tendency to not see lens purposes earlier than the lens comes out.

So whereas I’d like to say one or all of those are coming, that is merely a glance into Canon designs that they’re researching right now.
