<p>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.</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 :'(
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.

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?

There's no assurance this patent will result in a lens sold on the shelves, but if 10 years of digital photography didn't kill the 135mm f/2.8 w/ softfocus, it must sell well enough to justify it's continue production, and even upgrade.

I like the 100f2IS the most out of the bunch, but if the 135f2.8IS were extremely sharp wide open, it would be hard not to consider it.

But yeah, taking f2 away kind of kills the appeal. I assume most people are looking for a low light action lens or long portrait lens in the 135f2, IS does not replace a stop worth of aperture in either case.
The 35f2.8IS makes sense, this, not so much.
