Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2.8 IS

Patents: Canon 85mm f/1.8 IS, 100mm f/2 IS, 135 f/2.8 IS

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.

EF 135 f/1.8L IS [CR1]

From Anon
I’ve been sent info about an updated EF 135 f/2L. The source says we can expect it to get IS. It’ll either be f/2 or f/1.8. Both prototypes exist.

CR1 for now.

This is the first I’ve heard of such an update.

60D Image
There’s a 60D image making its way around the web. I haven’t posted it because it looks exactly like 50D pictures that are out there.

It’s extremely rare to see Canon promotional photos before a camera is released.
