Design and Features
A member of Sony's G Master professional series of lenses designed with emphasis on high resolution and high quality bokeh.
The lens barrel is heavy, dust-proof and water-resistant, made of metal. The lens mount is metallic.
The lens is equipped with aperture ring which allows manual aperture control with precision of 1/3 stop. There is a CLICK switch which allows user to choose between clickless and click-stop manual aperture control.
The lens features AF/MF focus mode switch.
|MF||Manual focus mode.|
During autofocus operation, you can press the AF Stop button of the lens to temporarily pause autofocus. This lets you stop autofocus whenever any unwanted obstacle comes closer to the camera than the moving subject you are tracking. If the shutter button is still pressed halfway when the AF Stop button is released, autofocusing will continue as before. The AF Stop function also works in continuous autofocus mode. You can change the functions of the AF Stop button using the camera's custom functions menu.
The lens uses front filters with standard size of 77 mm which are easy to find. However, filters of such size are more expensive and mainly used with professional lenses.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
