Leaked lens details - The F/11's look really cool

Some details are emerging and our first looks at the F11 super telephotos.  It does appear as if they are collapsable making these quite possibly ultra-compact for travelers.

Some leaked details on the extenders as well;

The 1.4x extenders 7 elements in 4 groups with a size of 71.2x20.3 mm with a 20mm lens ingress, meaning it will not work with RF lenses that have the element at the rear of the lens. It also weighes 225g.

The 2.0x extender is 9 elements in 5 groups, with a size of 71.2x39.3 mm, with 20mm lens ingress and a weight of 340g.

In both cases, the compatible lenses are RF100-500mmL, RF600mm, and RF800mm.  It appears as if the RF 70-200 for obvious reasons (the rear element position) is not supported.

I was sort of hoping that Canon got lazy with their earlier images and that the extenders shown were not the RF teleconverters, but it appears as if they were.
