Sony 35mm F1.4 G

The Sony 35mm F1.4 G is a fast medium wide-angle prime lens for Sony's full-frame and APS-C format SLT cameras. Sony reserves the 'G' designation for its highest-performance lenses and as well as being built extremely solidly, this lens gives excellent image quality. On APS-C cameras it offers an effective focal length of roughly 50mm, making it a useful 'standard' for everyday photography. About the only downside to this lens is that - like a lot of Sony DSLR lenses - it lacks a built-in AF motor, meaning that autofocus is driven from the camera body. As such, although focus is fast, it isn't silent, and full-time manual focus override is not possible.
