You don't always need hulking $15,000 f4 long-telephotos to do a job. Most cases, whatever is being shot using focal lengths like that will be cropped so even if the likely inexpensive f11 lenses are not fantastic on the edges, it won't matter.

Why are you posting in the m4/3 forum?

Perhaps because those Canon lenses are in principle very similar to what we already have been having for years in Four Thirds and Micro Four Thirds, and what he say may be true for some of them, too?

They are 2 shutter speeds slower in poor light than a F5.6 lens. 3 shutter speeds slower than the Olympus 300mm f4 with equivalent 600mm FOV.

No, they aren't. Because the camera is already 2 shutter speeds faster than Olympus, as it can and will be used with 2 steps more ISO, if necessary, without getting into a disadvantage.

The disadvantage is that you've given up any DR advantage you otherwise would have had at equal ISO settings [...]

Yes, but that's not a disadvantage of the Canon compared to the Olympus. It's a tie.

Only if you disregard (i.e., delete) the rest of my post. It can't be a tie because the distribution of the DR relative to middle gray is now basically different between the two systems. Which one ends up better will depend on the scene and the photographer's priorities for protecting highlights vs. improved shadow detail.
