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