![]() ![]() All the lenses in this tier are of a constant aperture and all except the 7-14 have internal focus and internal zoom, which is restricted to 2x or 3x times magnification. With the exception of the 7-14mm and 14-35mm they all come with a removable tripod bracket. Of increased construction standard and better optical quality over their 'High Grade' counterparts, these lenses incorporate all that the lower tiers offer while adding 'Focus Limiter' switches and 'Focus Stop' buttons around the foremost focussing ring.
