    Canon Full-Frame PZ Lenses Could Be on the Horizon

    By 9 Comments3 Mins Read

    Last month Canon announced the EOS R50 V alongside a new type of lens in the RF-S 14-30mm f/4-6.3 IS STM PZ. The “PZ” meaning the lens has a bult-in Power Zoom function.

    Over the last year or two, Canon has also released a new line of “Z” lenses for full-frame cameras, but they require an external accessory to give the shooter Power Zoom capabilities.

    It now looks like Canon is working on bringing some internal Power Zoom lenses to full frame cameras. This wouldn’t be such a bad idea, as a lot of people simply don’t want to spend $4000 on an accessory equipped RF 24-105 f/2.8L IS USM or the RF 70-200 f/2.8L IS USM Z.

    Full Frame PZ Lenses

    A recent patent shows that Canon is working on full-frame PZ lenses with a constant f/4 aperture. It looks like these lens designs would be more affordable non-L options for creators that still want the larger sensor.

    With the coming EOS R6 Mark III and potentially a new style of full-frame camera, there is going to be a market for them.

    Of all the optical designs below, we think the RF 16-35 f/4 PZ would be the most likely design that could potentially make it to market, its simply a focal range that has been around for decades and people know what it is.

    There is also an optical design for an RF 24-50 f/4 PZ, which would give about the same 35mm equivalent of the brand-new RF-S 14-30mm f/4-6.3 IS STM PZ.

    Would new ideas be welcomed? Of course.

    Summary

    As with all published patent information, there’s no guarantee that any of these designs will become consumer products, but we do think it’s highly likely that we do see full-frame PZ lenses in the future.

    3. I can understand there's a real demand for such lenses.
      Yet, I hope Canon do not forget that there's also one for TSE, Astro UWA, Telezooms, 180 macro, luminous standard zooms.
      I'm suffering from object-less GAS. :cry:

      Don't forget long 1:1 macro lenses! I overlooked the 180 macro, oops!
    6. On the G1Xiii I do like using the power zoom in it pre set focal length mode, so I can just jump 24, 28, 35 (equiv) etc and see what I’m at in the viewfinder. Also I have one of the custom modes configured to set the zoom at 35, so as soon as I switch the camera on its immediately a 35mm one. Works well for me.
    8. I always lusted for a 15-60 f/4 for APS-C with premium IQ and good closeup range (1:3 or 1:4). If the 20-60 f/4 will come to live it would be a good substitute - 32-96mm equiv would be fine. Better: On an R6 ii it is a 20-60 & in crop mode a 32-96 giving a wide range of possible applications! If zooming would be available with the canon smartphone app, it is possible to do zooms without touching (and shaking) the camera!
    9. I think a full-frame 20-60 F/4 if priced right would end up in my kit eventually as a smaller walkaround zoom on vacation and for video uses - a 20-50 F/4, which gives a little bit of ultra-wide and stays a little longer, would also be nice.

      24-50 could be a candidate, but I do think 16-35 would just be a little bit too short on the long end for me to use as a general video lens. 16-35 would be great for small gimbal stuff, which I'd guess would be good for vlogging but I'd like to see something that could give more of a medium shot with a mild amount of zoom.
