Anything new to Canon's macro glass quiver will be a welcome addition.
Hm, i have the 100mm 2,8L - I use it mostly for some portraits and occasionaly Macros for product shots. I must say that I actualy enjoy the lense. Is there something particular wrong with it, that I miss?
However, of course its very important for canon to include a good macro lense in the R lineup.
In my opinion 90% of the average photographers work can be done with a 24-70 F2,8 IS. However, I think for a truely unique lense lineup, Canon has to release this selection for the R mount, before it truely holds up to a professionals needs:
8mm Fisheye
11-24mm Ultra wide
16-35mm f4 Wide angle for travel
16-35mm f2,8 Wide angle
24-70 f2,8 general lense
24-105 f4 general lense for travel
70-200m f2,8 light tele
70-200mm f4 light tele for travel
100-400mm f 5,6 tele
200-600mm f5,6 sports and wildlife tele
800mm high end sports tele
24mm f1,4
35mm f1,4
50mm f1,2
85mm f1,4
135mm f1,8
50mm f2 Macro
100mm f2 Macro
60mm TSE
90mm TSE
In my opinion this is a perfect lineup to truely support pretty much any kind of professional work
