On walkies this morning, I carried the Sony A7Sii with an adapted Olympus Zuiko 85mm f/2 that I am testing. I will make a more complete review later (already have the test shots done), but thought that this sunflower with an out-of-focus bee was fun. The shot was captured at f/2 or f/2.8. I did a little post-processing in Iridient Developer (a recommended program, especially for Fuji X cameras) that included increasing the color saturation and vibrance a bit, adjusting the contrast to better cover the scene (and look my filmic), and bit of sharpening.
The lens is soft wide open. This is not unusual for vintage class and especially fast glass, like the 85mm f/2. It sharpens up nicely stopped down a stop or two. I like it.
