How about "no"? 70-135 f/2 is part of the f/2 trinity. Why would you want a 70-135 f/2.8 when the compact/light RF 70-200 f/2.8 already exists? Have you ever used it? The size/weight is perfect. If you like the idea of range-limited zooms with small maximum apertures, buy a GFX.I am very attracted by the 70-135L f:2 that is already announced, but the price and weight are going to be punishing. How about a 70-135 f:2.5 or 2.8 IS that one can hand-carry for more than 5 minutes, that is of a more mangeable form factor and that does not require one to mortgage the house to purchase it? I see gaps in the RF offering where we are seeing either good, reasonably-priced and quite OK lenses (35mm 1.8, etc..) or $2,500+ super-extraordinary L glass. The EF range has a number of very interesting L lenses in the $800-$1600 price range that appeal to non-professional photographers, will they ever be catered for (the 24-105L was a good start but I see no follow-up)?
