Sony offers several lenses for its mirrorless interchangeable lens camera (MILC) series, otherwise known as NEX. The New E-mount Experience (NEX) consists of several popular cameras including the Sony NEX-3, NEX-5 and NEX-7. Third party lens manufacturers are starting to hop on the E-mount bandwagon, and Tamron is the latest entry into the NEX lens market.
Tamron is known for its compact high ratio zoom lenses, and produces high-quality lenses for several different lens mounts in the digital camera industry. When it comes to the NEX 18-200mm lens model just announced this week, Tamron is competing directly with the Sony E 18-200mm lens.
