Canon should consider an EF125mm f2.8 (crop 200mm) and a EF150 f2.8 (crop 240mm) possibly making the EF150 marco along the lines of the EF100 f2.8L lens. Currently excluding the EF180mm Macro lens Canon goes from 135mm to 200mm in fixed focal lenght in standard form.
If they can make both to the optical performance of the EF100 f2.8L or higher then I think they will sell reasonably well.
