    ef1124 1536x518 - Canon RF 10-20mm f/4L IS STM announcement tonight

    *Updated* We updated the post to include image stabilisation and an STM motor, not USM. The lens has officially been announced.

    Well, if the report from The Camera Insider is true, we can knock one lens off the recent roadmap update.

    Canon will announce the Canon RF 10-20mm f/4L USM tonight at midnight EDT.

    Pricing is rumoured to be somewhere around $2300 USD.

    It appears as if the press announcement and a few images have leaked out already (thanks frankchn!)

    Canon RF10-20MM F4 L IS STM 

    Pioneering a realm of full-frame visual possibilities, the RF10-20MM F4 L IS STM lens further confirms Canon's excellence closely associated with its L-series lenses. This new addition introduces enhanced optical performance through a contemporary mirrorless lens design with a comprehensive set of features, including:

    • New Image Stabilization (IS) Technology: Reducing wide-angle distortion at the outer edges of the frame, ensuring precision and clarity in your shots.
    • Impressively Compact Size and Lightweight Design: Weighing almost 1.25 pounds (570 grams), this lens is roughly half the weight of the EF series 11-24mm f/4 L lens, making it a portable choice for photographers on the move.
    • Super Quiet Canon STM Focus Drive Motor: A highlight of the camera, especially for videographers, as it makes the lens ideal for video capture. This is the first appearance of this technology in a Canon L-series lens.

    Designed for professional videographers and stills visual storytellers, the RF10-20MM F4 L IS STM boasts a built-in lens hood and a convenient lens function button on the barrel. These features allow for a high degree of customization, including adjusting AF settings, Pre-Recording, Zebras, and more. Whether you're capturing landscapes, cityscapes, architecture, or even weddings, this lens is an asset that empowers professionals in different scenarios.

    Canon RF10-20MM F4 L IS STM lens is set to hit the market in October with an estimated retail price of $2,299.00. For more, please visit usa.canon.com.

    2. We’ll, that’s a really unexpected / oddball focal range. I can understand the 10mm range (there are a number of 10mm rectilinear primes currently available) to give this lens a slight benefit over the stunning EF 11-24mm f4 L. However, the long end is a bit short of the expected 24mm. Even 21mm would have been more useful.
    3. What's eye-opening is the rumored price of $2300, given that the EF 11-24/4 lists for $3000.

      Personally, I don't (yet) see anything to tempt me to swap out my EF 11-24/4 for this new lens. I suppose if the RF mount enables them to make a 10-20/4 lens that takes front filters and is substantially smaller/lighter than the 11-24 (e.g., about the size/weight of the RF 15-35/2.8), I might buy one. For me, the ability to drop filters in at the back is a big advantage of the EF 11-24/4 that I'm sure this lens will lack.

      For some announcements, I'd at least be sure to stay up until midnight ET to place a preorder...not for this one, I think.
    4. Rf10-20/4 without filters at a mid price (smaller/lighter?) vs ef11-24/4 with filters at a higher price.
      Given the rf14-35/4 has corrections allowing 77mm front thread then it will be interesting what the rf10-20/4 will have

      The real question is how long will canon still sell the ef lenses (not just stock left in retailers)

      If I understand the tradeoffs involved correctly, the benefits of mirrorless mounts with a short flange distance is most apparent at the widest end, so I am not surprised that they can increase the FOV at the same time while decreasing the cost, compared to the 11-24mm.
    7. If the price is too good, will be very software corrected......

      Don't think it is an unreasonably cheap price for that focal length on mirrorless. Laowa has a 10-18 f/4.5-5.6 for $700 for L, Z, and E full-frame.
    9. I had hoped for 10 but losing the reach to 24 is a big disappointment - it leaves a gap in coverage if I get rid of my 16-35 and carry only my 24-105.
      That 4mm gap means ~2 steps forward or a slight crop in post.
    10. If the price is too good, will be very software corrected......
      No doubt. That’s not a bad thing. The RF 14-35/4 is ‘very software corrected’ and the resulting corners at 14mm are as sharp as the EF 11-24/4 that has essentially zero distortion at 13-14mm (and the 14-35 frames at ~13.5mm after correction with DxO).
    11. Someone posted a press release early: https://www.redsharknews.com/canon-introduces-rf10-20mm-f4-l-is-stm-lens

      They say that like it’s a good thing. :oops:
    13. First time STM in an L lens? Strange choice but must be good if they put it there.

      They developed the pretty amazing nano-USM, hyped it how small it is, and then barely added it into any lens...strange
    17. Personally, I don't (yet) see anything to tempt me to swap out my EF 11-24/4 for this new lens. ...

      ...unless the minimum focus distance is in the almost-macro realm; then I'm interested. Laowa's 15mm is my favorite macro lens.
