Patent: Canon EF-S 20mm f/2.8 STM

[Canon Rumors]

Another lens patent from Canon, this time for an EF-S 20mm f/2.8. Are we going to see a series of inexpensive EF-S primes in the future? This is pretty close to the 24mm f/2.8 STM pancake though.</p>

If you are not selling enough cameras, upsell cheap and nice lenses (10-18, 55-250, 20, 24, 40, 50 STM) to those who have already bought your cameras in the past... Canon sells something to current owners of Canon cameras (most of those people would never buy a >$300 lens anyway) and in addition, they get the users invested in the ecosystem!

Looks like a great strategy to me!

I would prefer to see a nice new 20mm 2.8L & not an ef-s lens.

I would prefer to see a nice new 20mm 2.8L & not an ef-s lens.

Generally, primes within the range of a zoom need to offer something more than smaller size (faster aperture, macro, tilt/shift). Given the 16-35/2.8, I doubt we'll see a 20/2.8L. Now...a 20mm f/2L, that would be interesting.

It seems like a pancake. Maybe I would buy it, but I really just buy a EF-S 20mm F2 or F1.8.
I'm not a big fan of pancakes, but I prefer lenses the same size as Sigma 30mm F1.4 Art.

 

[Pixel]

Hallelujah! I'll be all over it. Perfect compliment to my EF 11-24 f4.

Or maybe an EF 20mm f/2.8 IS USM

There must be some accurate logic there, but I'm not surprised that we're seeing Canon finally put out some EF-s prime lenses: they are small, light, high quality, relatively cheap - enough to acquire a few over time without feeling it - and the APS cameras are becoming so good and offer such good value over FF, with the exception of ultra low dof system when they actually become as expensive, I can see why Canon has a growing commitment to the crop camera system.

The 'crop is dead' brigade are as deluded as the 'Exmor is King' brigade.

 

[Loswr]

The 'crop is dead' brigade are as deluded as the 'Exmor is King' brigade.

The two brigades need to form a united front: Exmor crop sensors cameras will kill Canon FF cameras (in fact, DxO says they already have).

 

[wsmith96]

I'm surprised they put one so close in focal length to the 24. I would have put one more in the 15/16mm range for a crop camera.

Yup. I'd love to have this...

f/2.8 is a bit slow for a prime. While I personally would welcome some wider, ef-s primes, I'd prefer to see them in the f/2 range (or faster). Otherwise, the only advantage over the many normal zooms out there (from Canon and 3rd party) is size/weight. Possibly IQ as well, however the IQ of the normal zooms are probably "good enough" for that not to be a real factor.

If the 24mm pancake did not already exist, this would be a lot more exciting.

 

[mrzero]

I would have bought this lens when I started in with a crop DSLR. I think the 24mm EF-S pancake is still too long on crop. 20mm works out to 32mm equivalent. However, a fast 14-16 EF-S prime would be spectacular.

Perhaps even 20/1.8L to match or better exceed Nikon counterpart Also while we're at it, I'd love 35/1.2L instead of mk II variant

There is no thing as "fast enough prime"

 

[gunnar997]

I own the 20mm 2.8... I shoot 5D3.. 20mm is kind of an awkward focal length on crop cameras.. Just make an IS version for both please! I'd love an IS upgrade on my 20mm.. even better I'd love what everyone else is saying of a 20mm f/2 and even better a 20mm f/2 IS.

 

[ashmadux]

Who would buy this? Probably one of the most boring lens patents in recent memory.

I would LOVE to have the 22/f2 in an EF-s version. That would be spectacular, love that little guy.

Cmon canon..

Where is the EF-S 30 mm f/1.4???

 

[Khalai]

Where is the EF-S 30 mm f/1.4???

Umm, IIRC Sigma has 30/1.4 Art

It's a shame that Sigma 30mm F1.4 Art does not have the same quality optics of 24, 35, 50 Art.

The 30mm art is pretty good consider its size (not counting the huge hood came with it). I used it for more than a year but just recently upgraded to the 18-35 f1.8. Lovely lens despite the size.
