Sony 135mm F1.8 ZA Carl Zeiss Sonnar T*

The Sony 135mm F1.8 ZA Carl Zeiss Sonnar T* is a fast medium telephoto prime for Sony's full-frame and APS-C format SLT cameras. This is an expensive lens, but you get what you pay for. The 135mm is beautifully engineered, and capable of excellent results. Traditionally a favorite of photojournalists and portrait photographers, 135mm is a useful focal length for landscape and candid photography, too. On APS-C format SLTs, this lens is equivalent to a 200mm lens, which makes it very handy for shooting concerts and indoor sports, as well.
