In addition to adding the fast normal prime lens to your camera bag, the Sony Sonnar T* FE 55mm f/1.8 ZA Lens with Circular Polarizer Kit from B &H also includes a versatile 49mm circular polarizer.
A perfect pairing for full-frame Sony E-mount cameras, the Sonnar T* FE 55mm f/1.8 ZA Lens offers excellent resolution and a fast f/1.8 aperture for photographers looking for a high-performing normal-length prime. By using three aspherical elements and Zeiss's legendary T* anti-reflective coating, this lens exhibits an absolute minimum of aberrations and flare. It also has a linear autofocus motor and internal focus design for fast, responsive AF and achieving a minimum focus distance of 1.6'. Additionally, the lens is dust and moisture resistant and uses a nine-blade circular diaphragm for smooth, rounded bokeh.
The Hoya 49mm alpha Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.
This filter is non-coated and has approximately 96% average light transmission. It is constructed from optical glass and precision milled aluminum frames.
