Sony SEL20TC
Doubling the reach of compatible Sony telephoto lenses while preserving autofocus, metering, and optical stabilization, this 2.0x teleconverter adds just 209g to your kit. Its dust- and moisture-resistant construction matches the sealing of lenses like the FE 70-200mm f/2.8 GM OSS, maintaining full-frame coverage without sacrificing communication between body and glass. This is best for street and portrait shooters who occasionally need extra focal length but don't want to carry a second heavy telephoto prime.
