Feb 12, 2021. First light with the Olympus 150-400/F4.5 (with built-in 1.25x which yields an equivalent 1000mm when set to 400mm). The E-M1X body was set to CR+TR and bird-detection for all flying birds and some perched birds. All 100% crop images were taken hand-held. Surprisingly, the bokeh is similar to my Sony 600/F4 when the background is far away.

Small finch-like birds, flycatcher?.
