BM Premium 420mm Lens 420-1600mm
Its extreme 420-1600mm zoom range, extendable to 1600mm with the included 2X teleconverter, provides reach unmatched by standard telephotos for Sony A-mount DSLRs. The constant f/8.3 aperture and multi-coated optics aim for clarity at extreme distances in a relatively lightweight 980g body. This lens is best for budget-conscious Sony A-mount users experimenting with very distant wildlife or static celestial subjects, where manual focus and a tripod are practical.
