This is the Perfect lens to walk around with. It is great for all types of Photography.

Delivering a "normal-length" 52.5mm equivalent on APS-C-format E-mount cameras, the E 35mm f/1.8 OSS Lens from Sony is a versatile and lightweight option that will fit a variety of shooting scenarios. It offers a fast f/1.8 maximum aperture for working in low-light and creating images with shallow depth of field. Equipped with one extra-low dispersion element and two aspherical elements, images will have an absolute minimum of aberrations. Also, it has built-in Optical SteadyShot image stabilization for reducing camera shake and creating sharper images and uses an internal focus mechanism that enables fast, responsive focusing as close as 11.8". Additionally, it has a seven-blade circular diaphragm for smooth bokeh.

Designed for APS-C-format cameras, this compact 35mm lens will provide a "normal" 52.5mm equivalent focal length.
A maximum aperture of f/1.8 offers excellent low-light imaging capabilities along with the ability to create images with a shallow depth of field.
One extra-low dispersion glass element is featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.
Two aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
Optical SteadyShot image stabilization helps to minimize the appearance of camera shake for sharper imagery when shooting handheld with slower shutter speeds. This stabilization system can be combined with select camera's sensor-shift type image stabilization for more effective control of camera blur.
An internal focus mechanism contributes to faster, more responsive autofocus, the minimum focus distance of 11.8", and easier handling as the lens does not change in length during use.
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
