Actually I just did the math... f/7.1 @ 500mm and f/5.6 @ 400mm is about the same size. So perhaps this lens is just extending the capabilities of the EF 100-400mm with an extra 100mm in reach? If that’s also the case, it will probably clock in at similar to slightly heavier weight than the EF.

it's not that simple, I imagine with the converters, the 100-500 might be unusable..... yeah, f7.1 is really slipping.  but it's good if you only live in that range and it's a damn good range.
