Patent: EF-S 30mm f/1.8 & EF 50mm f/1.8

[Canon Rumors]

A Canon patent was found over at <a href="http://www.northlight-images.co.uk/canon-ef-lenses-rumours-and-news/">Northlight Images</a> for a 50mm/1.8, which was replaced relatively recently, and a APS-C 30mm/1.8 lens has appeared at the Japanese patent office (No. 2017-102352 )</p>
<p><strong>Full frame lens specifications:</strong></p>
<ul>
<li>Focal length 51.60mm</li>
<li>F number 1.85</li>
<li>Field angle 22.75</li>
<li>Image Height 21.64mm</li>
<li>Lens total length 84.19mm</li>
<li>BF 39.08mm</li>
</ul>
<p><strong>APS-C lens specifications:</strong></p>
<ul>
<li>Focal length 30.90mm</li>
<li>F number 1.85</li>
<li>Field angle 23.85mm</li>
<li>Image height 13.66mm</li>
<li>Lens total length 84.50mm</li>
<li>BF 35.50mm</li>
</ul>
<p>There has always been rumbings about a “good” EF-S prime coming and 30mm has been passed around over the years, however nothing has every come of it.</p>
<p>The EF-S 35mm f/2.8 IS STM Macro hasn’t started shipping yet, while a very neat looking lens, it’s not exactly the “fast” prime people have been looking for from Canon for APS-C shooters.</p>
<p><a href="http://www.northlight-images.co.uk/canon-ef-lenses-rumours-and-news/">Northlight Images</a> does say that they’ve been told to expect a “good” EF-S prime in the future.</p>

I'm sure they're just adding it to the patent portfolio as a "just in case", but I can't help wondering if the world really need another 50/1.8 formula.

OH MY GOD IT MIGHT FINALLY HAPPEN

 

[Woody]

An EF-S 30mm f/1.8 will convince me to finally settle down to a 77D.

We shall see...

Why EF-S? WHY?!
??? :-\ :-[ :'(

Is the availability of fast EF primes not to your liking? You wouldn't just be happy with the 35/2 IS or the 28/1.8 or the 28/2.8 IS or any of the third-party options? Crop shooters, on the other hand, have very few crop-specific prime options, and no fast ones other than the apparently-mediocre 30Art.

I use the 28/1.8, it's not bad, I like it, the bokeh is very nice (unusual for a wide lens), but wide open it feels very outdated and it doesn't work that well (rather poorly) for landscapes. The 35/2IS is not it and the 28/2.8IS is a joke.
Finally, if you really love fast primes, then you better go FF in the first place. This EF-S 30/1.8 will only get you close to 50/2.8 on FF and not even a good one. I think that 50/1.8STM on FF at F2.8 will put it to shame for around half or 1/3 of the price.
On the other hand, if it was an EF 30/1.8, then maybe I could replace my old 28/1.8 with it. Which is why I'm 'facepalming'.
What makes you think that it will be better than the 30/1.4Art? It's not F1.4, so it already lost in aperture department. Sigma comes with a lens hood, one more point to Sigma. And it's a nice sturdy hood, unlike the rattling trembling Canon fashion. We'll see ...

You guys could be on to something in that the new 50 could be a macro lens or new redesign,notice its longer than the EF 100mm F2

What it calls the "total length of the lens" actually includes the entire path traveled by the light until it reaches the image sensor inside the camera. Thus, the lens itself, would be about 4.5 cm long.

[Don Haines]

DOOMED! DOOMED! Canon is doomed!

Since the vast bulk of their sales are crop cameras, offering a pair of primes specifically for those crop cameras is obviously an act of desperation..... and when they sell well, that will be further proof that they are doomed!

Seriously though, I bet if they make the 30F1.8, that it will be a good seller....

I have no idea if it will be better than the Sigma. I actually rarely use my cropper, and when I do it's usually for the flexibility of the 18-135STM. My question was about why you seemed so hurt that the new lens would be EF-S, because that focal length (especially give or take a few mm) seems very well-covered by existing offerings.

And I just bought the 24-70/2.8ii and 70-200/2.8ISii, so I'm not getting ANY new lenses for a while...

 

[msatter]

Indeed good is not good enough. They have to be excellent if not perfect for the big money they are asking for it.

I'm not hurt . Just saying (a bit sarcastically) that it would make much more sense (and profit) if it was an EF lens. All that Canon's self-competing phobia is silly. I think that crop shooters, who wanted their "fast" 50(ish) equivalent, already got the EF35/2IS or one of Sigma's offerings (30/1.4, 35/1.4, 18-35/1.8 ).

And the 28/2.8IS is a joke because... ?

Isn't the price doubling of an old and slow prime after adding IS, a joke? Thank god the 35 IS is not F2.8 . Same thing with 24/2.8IS.
I don't know ... maybe I'm wrong. What are you shooting with your 28/2.8IS? What's the best use for it? Shooting video on EOS-1D C?

28mm2.8IS has a new lens formula with an aspheric element and USM as well as IS. Greatly improved resolution over previous 28 is well documented. Not the same lens as the one it replaced. I use a 28 where others might use a 35, with a bit more width. You use the 28 1.8. I use the 2.8 IS. No joke.

The point of an EF-S 30mm is to take advantage of the smaller image circle resulting in a smaller cheaper lens. But I agree that the venerable 28mm/1.8 could use a replacement.

I think that to have a chance of success, any EF-S 30mm F1.8 would need to be smaller, lighter and cheaper than the 35 f2.0. Canon does seem to be competing pretty aggressively in the APS-C space these days. Is there any chance the 30mm patent could be applied to an EF-M lens design?

In addition to having a smaller image circle, an EF-S lens may not have enough clearance for the swing of a FF mirror. That is likely why a FF Canon camera will not accept an EF-S lens.

Yes, good point. A 30mm has to be retrofocal in both EF and EF-S but the shorter clearance of EF-S probably helps with the lens design anyway.

The EF-S 35mm f/2.8 IS STM Macro hasn’t started shipping yet, (...)

Not true. My local dealer (Düsseldorf, Germany) lists it as immediately available.

By "old and slow prime" I meant that it's not very popular in 21st century . The 24/2.8 is a much more desirable lens. Too bad it's not F2 . It is weird that a full stop aperture difference means nothing to you. I shoot people with my 28/1.8, so the blurry corners at wide open are not terribly problematic. But I cannot imagine using the 28/2.8 IS instead. It would produce absolutely different results and the IS wouldn't help a bit. Even for landscapes, the distortion would make stitching tricky or even questionable and 28mm is not wide enough to one-shot everything. Stitching 40/2.8 STM is a breeze - so sharp and well corrected. Canon need to make a new 20mm prime , IS or not, but F1.8 would be nice (like the Nikon one). However, I'm not going to buy a bunch of slow stabilized primes ($500-$600 each) in steps of just a few millimeters. That's madness. I'd just get a decent UWA zoom instead. Perhaps the Tamron 15-30/2.8 VC, or the EF 16-35/4L IS.
