Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2.8 IS
« on: January 21, 2014, 10:27:10 PM »

Patents with three popular telephoto lenses with the addition of image stabilization have shown up. It’s long been expected to see IS added to Canons highly regarded 135 f/2.0, I don’t know where a 2.8 will fit into the lineup, and adding stabilization to the 85 and 100 would follow with Canons current practice of sticking IS on all their mid-range glass.


Patent Publication No. 2014-10283

Publication date 2014.1.20

Filing date 2012.6.29


Example 1

Focal length f = 85.56mm

Fno. 1.86

Angle of view 2ω = 28.4 °

Image height Y = 21.635mm


Example 2

Focal length f = 102.06mm

Fno. 2.00

Angle of view 2ω = 23.9 °

Image height Y = 21.635mm


Example 3

Focal length f = 131.00mm

Fno. 2.80

Angle of view 2ω = 18.8 °

Image height Y = 21.635mm


Canon patents

Positive and negative positive

Inner Focus (group 2)

(Part of the third group) antivibration

Update: I accidentally read the135 f/2.8 as f/2.0, apologies for any potential false hope we brought.

Sigh. Patents, patents and more patents.

Very alluring, but they don't mean anything!

How long has it been since we saw the first patents on the 14-24L and the 35L II?  :P

I hope that's not the lens they actually release, although it would save me a ton of money.  Very sad indeed if it turns out to be a f/2.8 lens :'(

That's probably radius of the image circle.

Yup. I have the 135L, alongside my 70-200 IS II. Even though I love the 135, it does feel very unnecessary some times.  :P

A 135 2.8 would feel even more unnecessary!

But a 135 f/1.8 (and with IS).. Please give me.

That would make a rather pointless addition to the line up when the 70-200LII covers both of those criteria very well (f/2.8 and IS). And assuming it will cost in excess of $1000 there would be very few who would opt for it.

Just a patent mind, and it was filed 18 months ago. The 70-200LII had been selling well in that time. Could affect their final decision on the 135 IS.

5D II | 17-40L | 24-105L | 70-200 f4L IS | 135L | SY 14mm f/2.8 | Sigma 50 f/1.4

EOS M | 22 f/2 | 11-22 IS

I think I'll grab the 135 without IS once the new one is out...

Is 135 f2 going to be the only L lens among these three?

Focal length f = 131.00mm<
Fno. 2.80

lmao, Canon would release a 135mm 2.8 IS. A great addition to any kit with the 24-70 f4 IS.
My photography equipment goes here, apparently.

Looking at the linked website, I am very suspicious: all the block diagrams seem essentially the same, with different elements made smaller or bigger and shifted a bit. The 85 1.8, 100 2 and 135 2 don't look a bit like each other.
Now I am not very knowledgeable about block diagrams, maybe someone can give an expert opinion?
Someone's idea of a joke?
