Tamron has filed a new patent for SP 100-400mm f/4.5-6.3 VC lens. The size and weight of this new Tamron SP 100-400mm f/4.5-6.3 VC lens is expected to be between Panasonic Leica DG Vario-Elmar 100-400mm f/4-6.3 ASPH and Canon EF 100-400mm f/4.5-5.6L IS II. I believe this Tamron SP 100-400mm f/4.5-6.3 VC lens will be welcomed by most photographers.
