Capture photographs with your SP 150-600 mm DI VC USD G2 Canon EF mount lens in an extended focal length by using the Tamron 2x Teleconverter. It sports a BBAR (Broad-Band Anti-Reflection) coating that reduces flare and ghosting. The teleconverter features an ergonomic barrel design, which makes it easy for every photographer to handle. This teleconverter is constructed with high-quality die-cast aluminium, which not only makes it sturdy, but also resistant to dust and moisture. For safe storage, this teleconverter comes with a carry case and lens caps.
The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs.
