Patent: Canon EF 1000mm f/5.6 IS DO

[Canon Rumors]

<p>Howabout a 1000mm replacement for the EF 800mm f/5.6L IS? A patent showing the optical formula for an <a href="http://egami.blog.so-net.ne.jp/2016-06-06">EF 1000mm f/5.6 IS DO</a> has appeared.</p>
<p>We’ve seen the prototype for a future <a href="http://www.canonrumors.com/more-images-of-the-canon-ef-600mm-f4-do-br-lens/">EF 600mm f/4 IS DO BR </a>already, and the likelihood of seeing more DO lenses I think is pretty high. A 1000mm lens would be a great replacement for the current 800mm lens.</p>

if this lens becomes a reality, then its going to be one droool worthy piece of glass and metal.

 

[romanr74]

meh, this is so not innovative... : i'll have to jump ship...

Such a release would be quite smart. 800/5.6 is not attractive enough when there's a fantastic 600/4 around (and probably a DO version soon) that pairs well with the 1.4× teleconverter. And a 1000mm Canon lens with cutting-edge tech is certainly droolworthy.

 

[kirbyzhou]

Wonderful news, I hope the old 800/5.6 will be cheaper.

 

[hendrik-sg]

This is not a 1000/5.6, but a 950/5.8. it's about the same size as a 925/5.6 would be

But still, if affordable in relations of the big whites this would be great. But this pont i doubt if i look at the price of the 400/4 do

 

[dolina]

It will sell for $16,300 or more.

A bargain!

Considering Nikon launched their latest 800mm close to that price (I think it started with an MSRP around $18,000), and the use of a 178mm front element for something intended to cost less than a house, and the use of DO, if they can get it on the streets for less than $20K that would be fantastic.

Lets hope they shoot for a matching 500f2.8DO and 250f1.4DO to up the ante across the board.

Now I'm just curious, what F number would a 178mm element on a 125mm lens have?

 

[GMCPhotographics]

Wow...an ef 1000mm f5.6 L with IS, half the bulk and size and a lot less than $100K....sounds like it'll be a winner.

3 working examples.

1: 780 mm f/5.8, 389.21 mm lens length, for 135-format
2: 950 mm f/5.8, 485.94 mm lens length, for 135-format
3: 585 mm f/5.8, 292.50 mm lens length, for 135-format

Aberration graphs look very nice.

For comparison, EF 400 f/4 DO ii is 233 mm long, EF 600 mm f/4 L is 456 mm long, EF 800 mm f/5.6 L is 461 mm long, and the EF 1200 mm f/5.6 L is 836 mm long.

What kind of a job do I need to be able to afford this? It will be out of financial reach for 99%+ of mere mortals. Sadly.

Does anyone know what Shibomake is? Apparently this lens has both positive and negative of it. :A little googling just returns this general rumor.

 

[j-nord]

a 1000 DO makes more sense than a 800 replacement. Definitely an attractive offer for wildlife shooters who have a 2x glued to their 500 or 600.

1% of the population of mortals of the world is 70 million, which should keep the Canon production line going for some time.

f = 0.7.

 

[WRS]

Wow. I really hope this becomes a reality. I definitely think it makes sense to put a little more space between the 600 f4 and the 800 f5.6 replacement, particularly given how well the 600 works with teleconverters. Build it Canon!

Since these patents are likely the result of actually making something, who takes them for a "test drive"?

Or do the patents just reflect a working set of objective lenses without any electronics?

Generally, there is a proof of concept model or set of models for patents to show that the product can be built and works. They are hand machined or scavenge parts from existing lenses, or are just totally manual. Since the patent is for a optical formula, there is no need to have AF, IS, or a electronic aperture.

Some of these will appear at trade shows for PR purposes, like the huge MP sensors or 8K video cameras.

Since Canon has been trying to outdo Nikon by making a Wider Zoom, why not a longer telephoto. Certainly, there are potential buyers. I suspect that the cost of making such a lens would be a huge factor. The cost goes up exponentially for super long lenses, so trying to build one that would sell for under $40K might be a challenge.

I believe the OP'er was referring to only the current Canon user group - significantly less than 7 billion. Say around 10-15 million (this is a purely hypothetical WAG on my part), so maybe around 100,000 or so (1% of 10M)...
