The Sony 50mm FE F1.8 Lens is definitely a lens you should own if you are a full-frame Sony user. The prime lens is not only a very compact and lightweight build but is also a very affordable one. The 50mm lens works with all the E-mount cameras. The lens can be easily used on both full-frame and cropped sensor cameras. If you are using the lens with an APS-C format camera it will provide you with a 75mm focal length. The lens has a very fast aperture at f/1.8 that will give you much more control in low lighting conditions and may provide a shallow depth of field in your results. The lens also has a DC actuator motor built in. That helps it to quickly and precisely focus on a subject both in photos and videos. There is a rounded seven-blade diaphragm that provides smooth highlights to the image, it also helps with providing a smooth bokeh in both videos and photos.
