Well here's a fun optical formula from Canon discovered by Canon News, a Canon RF 135mm f/1.4L USM.  The Canon EF 135mm f/2L USM is an all-time classic, and this would certainly be an amazing offering worth of the new lens mount.

I think there is a higher than normal probability that such a lens design will make it into a consumer product.

Canon RF  135mm f/1.4L USM:

  • Focal length: 131.00mm
  • F-Number: 1.41
  • Half angle of view: 9.38°
  • Image height: 21.64mm
  • Total lens length:  182.28mm
  • BF: 13.87mm

  1. Be still my beating heart! If this comes to fruition I will be one very happy guy! Please Canon. Please! A native f/2 would be fine, f/1.4 would be sublime. Wondering what the front filter thread size would be. 105mm+?

    That would peak the chatter high. With eye focus on the EOS-R lineup, I would shoot 135 at 1.4 more often than needed. The image will be one of a kind. RF lenses seem to be smaller than the EF anyway.

    I don't know which RF lenses you are talking about being smaller (70-200?), but every RF lens I have is a monster compared to EF. However, I like that. ;)
  4. Wow, a classic lens where the new version could also be an instant classic.

    " consumer product " but business landing price. Would LOVE to see images taken by this presently hypothetical lens.
  5. The difference between this lens and a 1.8 or 2.0 will be $5,000 and triple the weight. Assuming we only get 1 L lens at this focal length, I would be happy to see this lens never get made, because I would really like a compact and fast 135 L lens
  6. Lens length: 2km Lens hood: 1km Total length: 3km Weight: an elephant!.. Price: 4500$... lol ... Even with this specs it will be an instant buy! (after 10 years of savings haha...) I hope this dream lens will come true! :love:
  7. Hmmn, I expect this would be an amazing lens - and probably render some amazing shots.

    However..... what I like about the existing (EF)135/2 is that it is also a pretty unobtrusive little tool, which gives great results but doesn't draw any attention at all. I can't help feeling that at 135/1.4, it will be a different kettle of fish - "great", but you won't be going around subtly with it.

    I disagree, a 135mm f1.4 need only have a 95mm front element, it’s not crazy like the larger than 100mm front elements on all the big whites. A 135mm f1.8 need only have a 75mm front element, or a 77mm filter thread.

    Indeed the RF 28-70mm f2 has a 95mm front thread and is $3,000, I’d expect a 135mm f1.4 to be mechanically simpler, a similar size, lighter, and less costly. I’d guesstimate the $2,499 prince point. A 135mm f1.8 should be considerably cheaper than that, probably sub $2,000.
  9. This plus a sports worthy R-series body would likely be enough to bring me back to Canon. I would fully expect this lens to be in the $6-8K range though.
    Why? That doesn’t make any sense or correlate with similar sized glass Canon already make.

    You only make my heart pump harder. ;) People seem to forget the Sigma 105mm f/1.4 and the price isn't out of line at $1,599. For a Canon? Anywhere from $2,699 - $4,000 would be fine with me. Can't take it with me. ;)
