If you believe there is little place for a 28mm prime and that 24 and 35 do enough for us, you are probably hoping this patent never materializes, and, say a non-L 50mm with IS materializes instead.

If you are an astro person -- fully recognizing 28 + 1.4 is far from perfect astro-wise -- you may still get a little excited that Canon might deliver the coma-free / fast / wide lens you've been waiting for.

If you love the 28mm focal length, enjoy your 28mm f/2.8 IS, or own the old 28mm f/1.8 USM and spoon with it at night like people did with their Amiga computers when they were discontinued, etc. you might be breathing into a paper bag right now.

Thoughts?

Patents are for a optical formula, so the formula can be expressed in different focal lengths and apertures. There are working examples (Physical models) crafted to demonstrate the patent.

Working Example 1 in the patent is 35mm

Working Example 2 is 35mm

Working Example 3 is 35mm

Working Example 4 is 28mm.

So why does Egami refer to it as a 28mm? It seems very unlikely and added as a after thought

I've seen this before, where one working example out of multiples ended up being a product. It was around the time of the slower IS primes from a few years ago. I'll see if I can find the patents.

Here's hoping. I love my 28mm f/2.8 IS. But this seems almost like a luxury FL with such solid primes immediately on either side of it.

[Marketing skeptic in me -->] How on earth would this crack even a top 5 list of most wanted L primes? In the next few years, should we not just expect a massive L standard prime refresh with the BR gunk? I'd think the 50L, 85L, and 135L would be locks for a 'BR refresh' before too long. The 24mm prime is more modern and might be at the end of that list.

But who is screaming for a 28L at any decibel level comparable to 24 / 35 / 50 / 85 / 135? I know they are out there, but there simply can't be that many of them.

28 1.8 needs updating but going from that lens to a 28 1.4L is a big jump that will incur a very big price increase. They can update first their 24mm 1.4L II to make a version III that is coma free. The version II has probably the worst coma in the world !

I'm sure that is the case, I just wonder why they picked the 4th example when their were three 35mm ones to choose from.

If Canon were going to make a 28mm f/1.4L, why not use the same formula as the 35L II. I suppose they could make a consumer version. Somehow, it seems unlikely, and so do the three 35mm versions for that matter.

Canon has long shown that it only loves astro photographers 2/3 as much as it could:

Of Wide / Fast / Coma-Free, you only get a choice of two. :'(

It is probably pretty hard to correct for coma without sacrificing corrections for more fundamental aberrations such as CA or distortion. The fast, wide and coma-free lens that is also sharp wide open is probably going to be Otus-like in price, size and weight.

Even then, the Otus 28 has problems controlling flare when you are taking photos with the sun in frame along the edges.

I personally just see astro aficionados as being too unreasonable. Some also tack 'inexpensive' to the end of that triumvirate and I giggle. Their dream leans appears to be a 16mm f/1.4 that's coma free for $999. :P

I wish them luck in getting what they want, I do, but each and every fast/wide lens gets them so excited and then the coma results sink it. It's happened a few times in the last 12 months alone. So they are stuck with a fairly coma free f/2.8 lens, which is like having a Ferrari you can only leave in first gear.

Corners are not fantastic on the 24L-II at wider apertures. I'd gladly trade in mine for a 18mm f/2 or 20mm f/1.8 with low vignette and low astigmatism.

p.s. I got a ride in a Ferrari a while back and it could exceed the speed limit in first gear.... and boy does it sing at high revs. :'( #tearsofjoy

If Canon makes a coma free 16-35 2.8 L III I will get it. I sold my 16-35 2.8 L (version 1) and got a 16-35 f/4L IS which I use for landscapes. It is coma free but it is f/4. Also 24-70 2.8 L II is coma free. So I believe Canon can make coma free lenses.Whether they will make and which lenses they make is a totally different matter...

More and more I hear comments about how the 28mm perspective is favored by a lot of shooters. And why not? To each their own. All FL's are awesome in particular situations and framing scenarios. I think this would make a fantastic addition to the L lineup if it's anything like the 35 1.4 mk2. Personally, I am liking having my 24, 28 and 35 all in one fat pickle jar.

Because Egami cherry-picks patent results in their titles and is a terrible resource to quote without question?

I currently have 8 lenses for sale, the one that has had least interest shown in it is the EF 28mm f2.8 IS. Which I am a little surprised about............

;D ;D ;D ;D ;D ;D Get the crap out of here!!! ;D ;D ;D ;D ;D ;D
I've been asking about this lens and would KILL to have it http://www.canonrumors.com/forum/index.php?topic=28604.0

Funny because I finally ended up getting the 35mm 1.4 BR because I didn't think something like this was going to happen. PLEASE CANON do it!!!! ;D

I love my 28mm's! https://www.youtube.com/watch?v=3c3nMO_Lxfk

After Tamron 24-70/2.8 VC those EF 24,28/2.8 IS seem like a bad joke even more than before :(. I think that instead of adding USM, IS and doubling the price, Canon should have made them STM and leave it at $300-$350.
The 28/1.8USM is teasing me for a long time :). Those closeup wide-open environmental portraits are very nice, but its dated optical performance is a bit disappointing. New fast 28mm USM under $800 would be great. Not sure about the twice as expensive 1.4L (for astro shooters), it could just lose it to 24mm and 35mm.
