They test it with the Sony a1 for sharpness, autofocus accuracy, bokeh, contrast, and stabilization. They test it with 2.0X teleconverter and it performs great, too. For comparison, the cloest Sony lens is the 70-200 f/2.8 GM II with the 1.4X teleconverter, so they use that to gauge sharpness and bokeh. 0:00 Introduction 0:58 Autofocus Accuracy 2:03 Autofocus Accuracy with 2X teleconverter 2:49 Sharpness vs Sony 70-200 f/2.8 GM II with 1.4X TC 4:18 Bokeh and Contrast 5:22 Macro / closeup capability 6:10 Stabilization Test 7:04 Summary
