A very mixed experience with the RF 70-200 f2.8

I wonder if Canon forced themselves to put a longer throw into the zoom ring because of the telescoping design. The seals and support structure for zooming that large chunk of glass and barrel probably need a lot more torque to zoom than the more traditional single barrel 70-200 lenses. Thus, the zoom ring seems geared to sacrifice throw distance for mechanical advantage.

I would assume, if the new RF 70-200 is up to the same build quality standards needed in other 70-200 lenses, the extending barrel had to be overbuilt like crazy to gain the same strength and coaxial alignment found on the single barrel lenses. Then they likely tossed in some thick and tight dust and moisture seals to keep the lens from gunking up.

It wouldn't surprise me if Canon came out with another 70-200 f2.8 RF lens using a single barrel design if there are enough customers who want ultimate usability and don't care if it doesn't collapse smaller.

Of course they did. It was obviously a trade off for the design. Canonrumors already went over the patent for a non telescoping RF 70-200 f2.8; if the market demands it, it will come.

actually we did

But yes, as we suggested, it makes sense for Canon to have multiple choices.  Let's face it .. on the EF mount they ultimately had 4 different 70-200's.

For the VAST majority of people, even professionals, I think the weight/size savings outweigh the costs of the design; Canon wouldn't of released the lens if they didn't believe this to be true.
