Overall

Sony E mount 85mm G master Block lens gives great sharpness and Bokeh & capture great details. So it’s a great lens.

 

Advantage of Sony E mount lens

-          Native AF system.

-          Benefits from all of Sony’s features including Eye AF

-          Works perfect with Sony A7s II, Sony A7R II, A7R, A7s etc.

 

AF / MF switch

-          AF/MF switches

-          Programmable Fn button (defaults to Focus Hold).

One can set the button to activate Eye AF for natural and easy access to the setting during use.

 

Operations

-          Rubberized focus ring helps you operate the lens smoothly

-          Improved focus-by-wire system helps these lenses to have a more natural feel does not seem to ramp up or down in speed depending on how fast you turn it.

 

Aperture ring

-          The integration of a physical aperture ring, allows to be clicked or de-clicked with a switch which makes it a great option for video shooters, as well as photographers.

 

Physical details

-          The small ridge on the bottom of the lens ensures that the lens’s aperture and focus rings are not lying directly on any surface when the camera is laid down.

 

Some Cons

The lens is slower than other native options due to the use of an older, and louder, Linear SSM system to move the large elements precisely, which could be changed by using the Direct Drive SSM available in many current models.

 

Chromatic Aberration at F1.4

There is a noticeable amount of chromatic aberration on high-contrast edges at f/1.4 which could of course be easily corrected in post

 

Tips : It gets better as you stop down, peaking at about f/4-5.6, where it will optimize the performance. Vignetting is also very well controlled and flare is nonexistent.

 

Focus Ring

There are still no witness markings on the lens and no hard end stops which makes them less appealing for use with follow and remote focus units.

They would work well with smaller handheld gimbals rather than larger Steadicams and gimbals
