However, the "800mm" is only 776mm, but the 700mm is a true 700mm (699.99mm).
The 200-1000mm would have to have an even larger front element, considering that the 800 (776mm) and the 1000mm (980mm) has the same f/9.18 aperture number.
The medium focal length f-numbrr is smaller than wide focal length.
If it is a L lens and near ef400 f4.0 do lens size.
I really want one.
But the size would be larger than 100-500mm f/4.5-7.1L x 2x.
Very strange.
I am curious about the entire focal range.
We can't assume anything.
If they really make it, it can be a video lens.
Canon had 50-1000mm but for super 35.
