    Canon Patent Application: Canon Standard Zooms

    By Updated:10 Comments Canon Patents 3 Mins Read

    One thing that Canon has done well with the RF mount is its normal zoom range with the likes of the RF 28-70mm f/2.0L, RF 24-70mm F2.8L, RF 28-70mm f/2.8 STM, RF 24-105mm f/4L, RF 24-105mm F2.8L, and finally the RF 24-105mm F4-7.1 STM. Whew.

    In this patent application (2024-160458) Canon is exploring the designs of some constant aperture fast normal zooms. A point to ponder is that it takes quite a bit of time to take a design from conception to production, and both the RF 24-70mm f/2.8L and the RF 24-105mm F/4L are getting “old” at over 5 and 6 years respectively.

    So it’s entirely possible that Canon is starting to think of the Mark II versions of the existing lenses.

    Canon RF 24-130mm F4 IS

    As previously mentioned, a new version of the Canon RF 24-105 f/4L and expanded to 24-130mm f/4L would be a welcomed addition. This lens does require image stretching on the wide-angle end and seems to be a little tight in terms of back-focus distance. The design seems rather straightforward and around the same elements/groups as the existing 24-105 f/4L, leading me to believe that it wouldn’t necessarily be the most expensive of lenses for Canon to develop. The Canon RF 24-105 f/4L is over 6 years old, so it’s due to be replaced sooner than later.

    Canon RF 24-85mm F2.8 IS

    This lens would have been intriguing if we didn’t already have a bazillion in the 28-70mm range for Canon RF. A slight expansion on the 24-75 zoom range, would be welcomed by some. The RF 24-70mm f/2.8L is now over 5 years old, so Canon will be starting to work on its eventual replacement soon. As with most RF standard zoom lenses

    As with all patent applications, this is a look into Canon’s research and we may not see products like this in the future.

    2. Nah, I would rather see a RF 24-70 F2.8L IS USM Mark II and a RF 24-105mm F4L IS USM II.

      It has been suggested that the 24-70 f/2.8 will be the first to get a v2. I wouldn't be surprised if they did actually change the range on the long end.

      I was talking to Bryan at The-Digital-Picture about the new 70-200 optical performance. Which is astonishing for a zoom. We think Canon has taken a leap with lens design software, optical engineering and manufacturing. The RF mount itself could be playing a roll.

      All of the popular zooms are probably going to get updates with whatever it is they have come up with.
    3. In the article there's a mistake, where you said "104", when what you meant--I'm sure--is "105". I would love to see a slightly longer 24-?. Nikon has long had the 24-120, so Canon should be able to match that in the very least. With today's noise reduction software, IMHO, maximum f/stops less than f/4 have become somewhat irrelevant unless you're a working pro. I understand the need for "speed" in both the lens and in production, but I'm not in that boat, not being a working pro. For me, there is also the weight issue, and lighter (weight) is always better.
    4. Both lenses look interesting. I'd love to see a 20-80 f4 but my heart wants an 18-50 f2.8. Still, the extension from 70mm to 85mm for the 24-85 is exciting if they can keep the lens the same size (or smaller!). I hope it becomes real.

      F stops also effect Depth of Feild for subject isolation as well as light gathering capability. I say light gathering rather than shutter speed as sometime people need to collect enough photos in the dark, IE astro, concert
    7. To me it really seems Canon started really good and specifically designed for RF mount glass somewhere in the year 2020. The 70-200mm F2.8 (announced Dec. 2019, hit the stores in 2020) was a beginning with the collapsable design (yet I´d be interested to if Canon would place the control ring differently now). The RF 100-500mm was really the lens that told me that great lenses are about to come.

      The first announced lenses all need a mkii version.

      1. 28-70mm F2 --> drop weight... like a lot! Sonys lens will probably put pressure on Canon.
      2. Redo the 24-105mm F4 --> make it sharper, sharper and if possible give it even more zoom range (or make it smaller instead).
      3. 15-35mm F2.8 --> lighter please, maybe make it 14mm as well
      4. 35mm F1.8 --> gear type STM!
    9. If they could improve IQ and size/weight for the 24 - 105 f/4 IS in a MK II, that would be my preference, vs. extending the range. If we're talking range extension, I'd like a new super zoom, 10x or better (i.e. 24 - 240).
    10. I also like the idea of a MK II for the ultrawide f/2.8 zoom. That, the 24 - 105, and the 100 - 500 are pretty much my go-to lenses....though I'm interested to see how the new 70 - 200 f/.28 performs with the 2x TC, i.e. how it compares with the 100 - 500 at 400mm wide open.
