10. Autofocus

The autofocus of the lens, joined with the Sony A7R III, is noiseless but not especially quick. Running through the whole distance range and confirming the focus takes a bit longer than 1 second. During our test we didn't notice either wavering of the mechanism or any focus pumping.

The speed improves a bit after switching on the focus limiter but still the lens never becomes a speed demon – the time needed after pressing the shutter release to take a photo amounts to 0.8-0.9 of a second.

When it comes to accuracy it was good. It's true the lens had more misses than the Sony FE 135 mm f/1.8 GM but their amount wasn't worrisome, especially for a product from a third-party manufacturer. During our test over 95% of shots were properly sharp and the focus was set where we wanted it to be – not bad at all.

We also didn't notice any distinct front or back focus tendencies.
