UPDATE
The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being. I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure. ------------------------------------------------------------
Re: Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2 IS
Okay, so now it is starting to get interesting...
Unless Canon has learned the lesson from the latest release of the non L lenses with IS.
But a optically really good 85 f1.8 would be one on my wish list as I am not so happy with the actual lens.
A 100 f2.0 is also very nice but too close to the former and i prefer the 85 mm reach.
Now let's wait (further on) and see and save up some money...

I fear, you will have to add up another 100 to 200 $.Lee Jay said:

That is really disappointing, if this is the patent coming to release. :'(bchernicoff said:

Re: Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2 IS
I don't see the point of a 135 f/2.8.
At the time of superlative sharp f/2.8 zoom lenses (24-70 II and 70-200 II), why would you buy a 135 that doesn't add anything "big" to your pics ? Maybe a tiny little bit sharpening ? Is it really worth it…? For me, it definitely ain't.
Maybe a quite long prime lens for the 16-35 ; 24-70 owners.
But i feel it would be a real "downgrade" if it actually is 2.8. Why get less if you pay more ? The 135 f/2 is a beloved glass and is already super compact.

Ok, I'll try this again.
I think this is a FAKE post.
Just look at the block diagrams before you get too excited!

Re: Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2 IS
As someone mentioned before, the 135 is *NOT* f/2 and is *NOT* a replacement for the 135L.
The 135 shown here is f/2.8, and is a replacement for the now discontinued 135mm f/2.8 Soft Focus.
The 135L will have its own replacement that is f/2 (and hopefully IS, too, given the focal length).

Re: Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2 IS
Furthermore, as these lenses are very similar in focal length, their block diagrams are naturally going to look very similar. The difference between an 85mm and 100mm lens is tiny; thus why their current iterations are very similar in optical quality. Below are the current 85mm and 100mm lenses. Obviously IS shifts things a bit, but notice that their diagrams, at least in the front groups, are basically the exact same.
PS: Red scare text in capitals isnt really going to make anyone read your point
The reason you are getting no traction is because this is always the source of patents for canon lenses. If this is a fake post, so are about 1,000 others on Canon patents.sagittariansrock said:

Of course, I also think a 135mm f/2.8 IS would be dead in the water as well. Who would buy it? It'd have to be priced under the 135L, and less than an 85 and 100 IS lens to even gain traction. More likely its just to protect the design

Actually, the 135mm f/2.8 is discontinued. I don't think Canon officially discontinued it, but, try and find it from a reputable dealer anymore...it's dead. The price of the 135mm f/2 coming down a lot basically killed it.Ellen Schmidtee said:

Re: Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2 IS
Sorry if it was too crude, although clearly it made someone more knowledgeable (you) read them
Wasn't trying to scare anyone or seek attention, but I was just trying to get some clarification (I'll change the color). Like many, I am also an interested party and would like to know if this is genuine.
As I clearly mentioned, I am not an expert on block diagrams, but-
The IS elements are at the very back. Is that common?
As you mentioned, 85 1.8 and 100 2.0 are similar. However, 135 2.8 is wildly different.
Finally, while this might be a reliable source otherwise, that doesn't mean it can have false information.
Anyway, thanks for listening.

Re: Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2 IS
It's interesting to see that the 135 f/2.8 Soft Focus isn't available at any of the major retailer's sites or from Canon's shop, but it's still listed in their line-up. I realize it's quite out-dated, but it's been available pretty recently, from what I can remember. Maybe one or all of these lenses are coming soon?
Also, with regards to the lens diagrams, take a look at the Mk II super telephotos - they are all nearly identical to each other - so it's not hard to imaging that these lenses could be as well given their similar focal lengths and Canon's desire to streamline design and manufacturing.

Re: Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2 IS
This is an easy one
Personally, I think the 135L f/2 will also be discontinued, and replaced with a 135L f/2 IS for double the price; 135mm is long enough where you really see some large benefits w/ IS.
As a result of that, this 135 f/2.8 IS lens will then be the only 135mm prime choice in the $500-$1000 range.

For me a good reason to keep my 135 f/2
It is a very good lens
