Patent: Canon RF 19mm f/2.8 IS

[Canon Rumors]

Canon News has uncovered an interesting optical formula patent for a small prime lens with image stabilization. The patent talks in-depth about making small prime lenses with IS.
There are two different embodiments for a Canon RF 19mm f/2.8 IS.
Canon RF 19mm F2.8 IS

​Focal length 19.50mm
F-number 2.88
Half angle (degree) 47.99°
Image height 21.65mm
Lens total length 96.33mm
BF 18.34mm

Canon RF 19mm F2.8 IS

Focal distance 19.29mm
F-number 2.86
Half angle (degree) 48.30°
Image height 21.65mm
Lens total length 96.59mm
BF 18.43mm

This patent also includes an optical formula for an RF 85mm f/1.8, but I think it’s safe to assume that this won’t become a consumer product since we have the Canon RF 85mm f/2 IS STM.

Canon RF 19mm F2.8 IS?

Canon thinks it could double as a general purpose ultra wide prime?

Good to hear about non-L glass in the pipeline, and with IS. While L lenses remain crème de la crème professional tools with record-setting wide apertures, high standards for robustness, weather-seal, etc.. the non-L products are delivering on the whole excellent image quality and offer benefits for e.g. travelers such as compactness, lesser weight and more discrete appearance. Oh, and affordability!

Back in my film days I bought a used Canon 19mm lens. I was amazed at its image quality and lack of distortion. Maybe I'd be less amazed now, but I recall that it took good pictures. Before I got it, my widest lens was 28mm.

I would love a lens like this...great option for UWA photography in a compact lightweight package. If it's optically excellent, could be a wonderful option for grabbing with the 35/1.8 and 85/2 for a good quality compact carry.

Yes, just add a 135mm f:2.5 IS and/ or 200 mm f:4 IS

In film days I often traveled with just my 28mm, 85mm, and 200mm lenses. I rarely missed having anything else along.

My FD bag had the 24mm, 35mm and 100mm lenses, which covered most needs. I would eventually add the 17mm and/or the 200mm f:4. The 50mm macro and 300mm f:5.6 were for special occasions only.

Please Canon, an astrophotography capable RF lens to compete with the Sigma 14mm f/1.8. This lens is neither wide enough or fast enough for optimal nightscape shooting IMHO. I have the money sitting in my bank account ready to be spent if they cover that market segment with an RF mount lens.

19mm is an interesting focal length, but no reason why they couldn't make this and advertise it as slightly wider than a 20mm prime.

On another hand, could this be a cheaper lens? If it was cheap enough to have a bit of distortion, some auto correction could make this into effectively a cheap 20mm. Just throwing out ideas, though, not sure if they'd do that.

Interesting idea, and quite possible IMO – I do suspect this lens would end up as an RF 20/2.8 if it makes it into a product. Canon has done this with EF-M lenses already (wider than stated FL, camera crops the RAW image to the stated FoV).

Not just EF-M. With RF glass as well. See the RF 24-240mm, which in truth is much wider but has dark corners without the digital crop applied.

I believe the RF 24-105 STM is also employing this technique, although less intense.

I would love to see a 24-200mm F4L IS for a one lens solution for landscapes and even videography during the day. It would be a great travel lens.

 

[dlee13]

This is the travel lens I need! I really hope Canon makes it!

Manufacturers don't seem to care with slower short telephoto primes anymore, since the RF 70-200/4 IS is actually smaller when retracted and the minimum focusing distance can be much shorter as well.

But the 135/2 and 200/2.8 II adapted EF lenses both do the job just fine (in fact, better than they ever did with the IBIS + full area AF tracking) if one is looking at cheaper options.

 

[AJ]

Hopefully it's better than the old EF 20/2.8. I used to have one and it was a mediocre lens, and that's being generous.

 

[aboo]

Just get on with it please, Canon!

Been waiting now for wide primes... anything from 18 to 24 will be an insta-buy for me.

Over two years in to the system now - and the only RF wider than 24 is a big and heavy $2500 monster.

I bought that lens recently and adapted to my R6. It really is quite lovely. The FL 19mm right?

I assume so (without digging it out of the closet to check). I think all my lenses were FL.
