As usally I test new lenses on my testing wall. It is very helpful to find quality issues like with my Sony Distagon T* FE 35 mm F1,4 ZA (check out my test HERE). It also help me to find strength and weak points of my lenses. I always test three zones.
- A - Center
- B - Edge
- C - Corner
The focus distance for the Sony FE85mm F1.4 GM is 2.69m (8.82 ft).
It is always helpful if there is a compentitor to compare and rank the results. I used my Sony G OSS 90mm F2.8 to compare the lenes. The focus distance of the G 90 was 2.99m (9.8ft) to compensate the different focal lenght. The macro lens is the sharpest native lens in the Sony E-Mount, so it is a strong compentitor in this kind of testing.
Zone A - the Center
The results are really good. The G-Master is razor sharp even at F1.4. The lens is sightly better than the Sony G OSS 90mm F2.8 over the full range.
Zone B - the Edge
The good results are shown in the edge again. Even at F1.4 is the edge crisp an clear. The macro lens loses over the full F-Stop range.
Zone C - the Corner
As I have seen the corner I was a bit flashed. This lens is at F1.4 razor sharp even in the Corner. That are really amazing results. Sony did a very good job!
The lens is sharper over the full frame than the Sony G OSS 90mm F2.8

Shooting charts worth nothing at the end of the day if you can't confirm them in real live shots. My cat is a very good victim to check the lens sharpness in studio.
Both lenses are tak sharp and I'm sure you won't see a different even at large prints. But you can see the Sony G-Master FE85mm F1.4 is sightly sharper than the macro lens.

As usual I get asked for focus at infinity shots. So I made a landscape comparision shot. I need to say it was a bit windy at this day but I think this shot is good enough to show the performance.
I see more details in the shot from the Sony FE85mm F1.4 GM. It has also more punshy colors.
