There’ll clearly be extra RF-S lenses coming coming this 12 months in addition to subsequent 12 months. At present we see a patent for a few RF-S optical formulation. Certainly one of these optical formulation will doubtless be near a future product by the appears of the designs.
The idea right here appears to be a mixture of the EF-S 17-55 f/2.8 USM and the EF-S 15-85 f/3.5-5.6 IS USM. We might see the RF-S 15-85mm f/2.8-4 IS USM being the likeliest product to return from these optical formulation.
