It looks like Sigma has 3 lens announcements coming later this month or in June. We’re going to see one full-frame lens, and that’ll be the 200mm f/2. Sadly, we won’t be getting that for the RF mount.

What could we see from SIGMA?Summary

What the RF mount is likely to get from Sigma is two new APS-C lenses. Sigma currently makes 4 prime and 3 zoom lenses for APS-C RF mount cameras. All of which are quite good.

Maybe we shouldn’t assume that the APS-C offerings coming from Sigma will get RF mounts.

What could we see from SIGMA?

We don’t think we’ll be getting another superzoom, as Sigma recently launched the Sigma 16-300mm f/3.5-6.7 DC OS Contemporary. Sigma never did a “DC” lens longer than 300mm for the EF mount that we can remember, and we don’t think that’ll happen for RF.

  • 24-450mm (35mm Equivalent)
  • HLA-Driven High-Speed AF Motor
  • Optical Stabilization & OS2 Algorithm
  • 1:2 Max. Magnification at 70mm Position
  • Dust- and Splash-Resistant Design

We could possibly see a fast prime lens wider than the Sigma 16mm f/1.4 DC DN Contemporary. Something like a 10mm f/1.4 DC DN would be nice.

There could also be a possibility of Sigma doing an 85mm f/1.4 DC DN, which would be a 135mm full frame equivalent.

On the zoom side of things, I have no idea what Sigma would come up with for crop cameras. They always did things a little different in the EF days and that could continue.

Summary

The Canonverse is very quiet now, and it looks like Sigma and Sony want all the attention this month.

More RF-S options would be great. It’ll be interesting to see if Canon lets the third-party makers get in on the PowerZoom functionality that was recently featured in the new RF-S 14-30mm f/4-6.3 IS STM PZ. I don’t think it’ll happen and maybe that’s where Canon will put their focus when it comes to APS-C lenses.

We have been using the Sigma 16mm f/1.4 DC DN Contemporary with the EOS R50 V and it has been a terrific combo.

  1. Please please, 18-35mm f/1.8 successor Sigma! The original is still great even on dense sensors like the R7, but with 12 years of technological advancements I'm sure you can make it smaller, lighter, quieter, and maybe even expand it's focal range! They made the full frame equivalent 28-45mm f/1.8 recently so it's beyond time to update the legend.

    For the second lens, I'd like to see a stabilized general purpose bright zoom, like that RFS 15-60mm f/2.8 that was patented but nowhere to be seen. Since Tamron's in no rush to port their 17-70mm f/2.8 to RF for some reason, I'd love to see Sigma take a stab at a competitor.
  4. I know I’ve said this a hundred times, but I’m still hoping for an RF-S version of the Sigma DSLR 17-70 f/2.8-4|C. I know it’s a pipe dream since they have the 18-50 f/2.8, but for me it’s a much more versatile range, and I don’t mind the variable aperture.

  6. Wild Idea: But what about a 16-50mm f2 and a 50-130mm f2?

    Though a 50-150mm f2.8 is very likely to complete the holy trinity of fast APS-C lenses from Sigma.

    I really like the 18-35mm and 50-100mm f/1.8 EF-S lenses. Oustanding IQ. However, big and heavy. 16-50mm fF2 & 50-130mm F2 would be awesome if they can be kept to small size and lightish weight. I have really come to appreciate the compact size and great quality of the Sigma RF-S lenses and use them mostly with the R50 for portability.

    For portability, even a 50-100mm f/2.8 could be a great companion to the current 10-18mm f/2.8 and 18-50mm f/2.8 lenses. Longer than 100mm would great, but not at the expense of portability.
  8. I don’t really look to sigma for crop fast zooms. They are fine (briefly had the 50-100 1.8) or I trust fine. I love my 56 1.4 EF-M. But the fast zooms are so heavy I didn’t / wouldn’t use them. Compare 700 grams for the 18-35 1.8 with, say, 495 g for the 28-70 2.8 on a RF, lighter than an r7-hypothetical sigma combo, same speed, wider range, and I’m guessing similar or close image quality.

    I tried put the Sigma EF 17-70 with speedbooster onto R7/R50. If you are willing to sacrifice the corners(32>27~28MP for R7, 24>20MP for R50/100/10/50V) or shoot in 1:1 ratio instead. It's feasible.

    The 18-50 f/2.8 weighs 300 g while the 10-18 f/2,8 weighs 270 g. I own both and they are both excellent. Update: perhaps you should be comparing the 18-35 Sigma with the 28-70 f/2 Canon.

    Correct me if I'm wrong, but aren't speed boosters used to keep the same effective FOV and f/ratio when adapting FF lenses to crop bodies? The Sigma 17-70 is already a crop lens. Maybe that's what's killing your corners.

    Why use the speedbooster and not the normal RF to EF adapter? the 17-70 is already a crop lens and works perfectly corner to corner on RF aps cameras...
  15. With all this talk about exotic lenses with F2 etc, we still don't have a proper 15-70ish F4 zoom, first thing first, that's what I want.

    But I doubt that Canon would let Sigma do that. If the 7rII is upmarket I think a proper wide angle zoom is something Canon will launch with the 7RII. That's what I'm hoping for.

    It's not limited to FF lenses, I want the lens "faster" and wider

    Just experimenting. I have 18-50 now for the standard zoom purposes, 17-70 becomes redundant so I tried to make use of it.

    I completely forgot about the sigma 18-50. I try not to talk about lenses I haven’t owned or at least handled, but that doesn’t mean I should forget to mention them. The 18-50 is light and goes great with aps-c, but it’s FF comparison isn’t a 28-70 f2 or 2.8, but I guess in EF the 24-70 f4, which is much heavier, still faster (f 4.5 is the FF equivalent) much wider on the low end and a little less telephoto on the long end. Or the 24-100 4/7.1, wider and faster on the low end, longer and much slower on the long end, 95g more. I’d think the 18-50 wins on size and matchups enough that I’d much prefer it to any other standard zoom on rf-s. I use three formats a lot, and I feel like even I forget that the lenses are slower on APS-C, and also forget that I can get good or great subject isolation with an f3.5 or f4 lens on full frame, just need more intentional planning and sometimes the full frame solution is lighter. I much prefer the Sigma 56 f1.4 to the RF 85/2, even if the RF is a little faster, because the combination is so much more compact. The Sigma was even better than the of EF 85 1.8, a small and light lens, because that lens benefitted from being stopped down. I am willing to bet that if Canon does release a 70-150 2.8, it will be much lighter than the sigma 50-100 was/is, for the same speed and probably IQ.

    That's fine if that helps your creative process. But you can't blame the Sigma lens for degradation in the corners because the booster is compressing an image circle that doesn't go all the way there.

    50-200 2.8 and we have a deal.
    even 50-250/300 f/4, i accept anything with constant aperture.
