Patent: Canon EF 28-560mm f/2.8-5.6L USM

[Canon Rumors Guy]

<p>A patent showing another crazy superzoom has appeared, this time the optical  formula is for an EF  28-560mm f/2.8-5.6L USM. We’d  assume such a lens would also have IS if it ever came to market. We expected to see a non-L superzoom sometime in 2016, but that has apparently been put off until late 2017 at the earliest.</p>
<p>Patent Publication No. 2016-142795</p>
<ul>
<li>Published 2016.8.8</li>
<li>Filing date 2015.1.30</li>
<li>Zoom ratio 18.86</li>
<li>Focal length 28.80 119.57 543.20</li>
<li>F-number 2.88 4.56 5.88</li>
<li>Half angle of view (degrees) 36.91 10.26 2.28</li>
<li>Image height 21.64 21.64 21.64</li>
<li>The total lens length 281.07 331.07 385.01</li>
<li>BF 53.05 61.31 40.00</li>
<li>The effective diameter of the front lens 120.00</li>
</ul>
<p>I’m not sure this is a superzoom we’re likely to see, but all indications point to Canon definitely developing a replacement for the EF 28-300mm f/3.5-5.6L IS.</p>

For broadcasting or the cine line may apply. For photo I'd stick to a Powershot 25x (25-625mm). ;D

Odds are high that such a lens would include a 1.4X built in teleconverter, like the 200-400. Still, what a huge range. And a huge lens! About the diameter of the 400 f/4 DO, but longer and heavier even if DO optics are potentially employed.

 

[Chaitanya]

That's going to real pain in back to carry around.

I guess the rumored super zoom might be a 200-560 or a 300-560 instead of going to 600. It looks like they can do a 560 f/5.6.

 

[SUNDOG04]

An affordable 200-560 or 300-560 would be ideal. I use a 6D with lenses that cover 17 to 200mm. Currently if I were to do a once in a lifetime trip to Yellowstone and/or get into bird photography, I believe I would keep my Canon gear, but buy a Nikon crop camera and their new affordable zoom.

Get with the program Canon.

560mm at F5.6?

Even in a fixed lens you are looking at a large and expensive lens..... make it a zoom and even more so!

My bet is that this is not for stills cameras.......

Think of all the room and weight you'd save!

FWIW, the final picture in the patent is of a DSLR with lens attached.

could you copy the picture and post it? Thx!

The present invention relates to the imaging device which has a zoom lens and it, for example, is suitable as an imaging optical system of imaging devices, such as a digital camera, a video camera, a camera for broadcast, a camera for monitoring, and a camera for film photos.


[Effect of the Invention]
[0011]
According to the present invention, the zoom lens with which high optical performance is easily obtained covering all the zoom ranges and whole object distance by a high zooming ratio is obtained.


Fig.10 is an essential part schematic view of a digital camera (imaging device) provided with the zoom lens of the present invention.
[0018]
The zoom lens of each working example is a zoom lens used for imaging devices, such as a digital camera, a video camera, a camera for broadcast, a camera for monitoring, and a camera for film photos. The zoom lens of an working example can also be used as a projection optical system for projection devices (projector)

Would be nice to have this lens if optics are acceptable

Assuming that optics are OK, I'd still wonder about hauling a huge lens around. Usually, you need wide angles when there is little space, but the lens might take up a good bit of available space, not to mention its weight.

I've had the 35-350mm L and 28-300mm L and optics were fine, not great, but more than adequate. But packing one around not only grabs unwanted attention, but they are cumbersome too.

If optics were decent, not bad, especially for sports. I could see this as a lens for people shooting football, athletes, etc, who may be throwing a 2x on a 70-200, and with decent optics, could cover the 24-70, 70-200, 70-200 + 2X and still have almost 30% more reach, not to mention faster AF without the 2x.

I would much prefer this beast going out to 560 and drawing me in for that 200 - 560, than a 28-300.

Not for the weight-weenies, but LOVE big glass

Dear Canon delevopers,
when reading this :

Please consider also walk around photographers!
Many plp want so see new patents for light 300mm or 400mm L lenses
with reason able pricing. (update of 300mm 4L IS and 400mm 5.6L)

Cheers

I don't think that anyone has made a 20X zoom lens with sharp optics..... As to decent? depends on how you define it..... I have the 18-200F5.6 and although quite convenient, the optics are terrible!

Now a FIXED 560mm F5.6???? I'd jump on that one.... or an "L" 400F5.6 with newer materials......

a prime in the 500-560mm range f5.6 IS L would definitely get my attention, especially if they can keep it under $2500

500 f/5.6 or 400 f/4(non DO) are two lenses I would be interested in getting for occasional birding or mammal shoots. Lets hope Sigma decides to release a lens with those specs and below 2500$.

If I spend that much on a lens it better have 1st party AF speed, accuracy, and consistency especially when talking about birding.

 

[kanehi]

I wonder how much this lens is going to be and it looks massive and heavy. Will see this lens on sporting events on TV.

 

[neonlight]

I agree that this is likely to be a cine lens (without IS). But guesses have been proved wrong before.
