Re: Teleconverters RF vs EF

There's already a decent amount of air between lens groups in a longer lens like the 100-500mm (or especially the 600mm), so I honestly don't think the optical impact of the amount of air between the rear element and the teleconverter is enough that even the highest resolution sensor available today could measure it.

yes, and typically there is even more air between the front element an the subject, particularly at 600mm. Not to mention between the left and right ear of most photographers
