Spanning a versatile and long-reaching focal length range, the Canon EF-mount SP 150-600mm f/5-6.3 Di VC USD G2 from Tamron is a 4x zoom covering telephoto to super telephoto perspectives. Complementing the long reach is an optimized optical design that features three low dispersion (LD) glass elements to reduce chromatic aberrations and color fringing throughout the zoom range. eBAND and BBAR coatings have also been applied to reduce ghosting and flare when working in strong, backlit lighting conditions. Beyond its optical attributes, the G2 version of this lens also incorporates a FLEX ZOOM LOCK mechanism to permit locking the zoom position at any focal length position to prevent accidental zoom extension. Conventional zoom lock is also featured to prevent barrel extension during transport.
