You're right, the next picture makes the 100-500 indeed look narrower: https://www.dpreview.com/articles/3...rf-100-500mm-lens-under-glass-at-wppi?slide=8
I am curious about the weight(given how much Canon shaved off from 70-200) and how well its close focusing abilities are compared to EF 100-400mm as it will pair nicely with the rumoured APS-C RF based camera for both butterflies(larger cannopy fliers) and skinks which tend to be shy and even 180mm lens is useless for these critters.

I currently use the RF 24-105 f4L and have been looking at the RF70-200mm but the price is eye watering. I've never used a teleconverter and wondered if the 2x converter would work with my current lens? Seems a better option than paying nearly £2700 for the 70-200mm. Anyone familiar with using teleconverters? I Know I might lose a stop or two and hopefully the new announced converters will be compatible.

Have a look at https://www.canon.co.uk/lenses/canon-rf-24-105mm-f-4l-is-usm-lens/specifications/ and scroll down to "Extender Compatiblity". It looks there are no RF lenses available from Canon that will support extenders. The RF100-500mm could be the first.

I believe "traditionally", extenders were compatible with most white lenses, but I don't recall a black EF lens that could use them. Now that we're in the RF zone, I suppose all bets are off.

The EF 135mm f/2L takes the extenders. I believe the EF 180mm f/3.5L Macro also works with them.
