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 will 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. So this new Tamron SP 100-400mm f/4.5-6.3 VC Lens is expected to be a smaller and cheaper competitor to the Canon EF 100-400mm f/4.5-5.6L IS II USM lens.
