Mechanical shutter ? I mean zero shutter roll, so I’d assume….

No, ES on both. Zero shutter roll for two reasons: no verticals in the background, and the birds were basically hovering. You get rolling shutter on a fast pan with a busy background. Quality fast pans with a hummer in full speed flight are few and far between.

No shutter roll because the wings are at their limits of travel. At the point when the wings are reversing direction, they are essentially not moving, or moving at relatively low speed. At any other position in their travel, electronic shutter can show extreme distortion of the wings.

That explanation doesn’t make much sense to me given the long read time of the sensor - the wings should have moved to a different position between start and end of the read cycle.

Hummingbird hovering wing flap rate is 10 to 80 per second and so even at the low end of that range the wings would have gone through 30% of a cycle during the 1/30 sec sensor readout.
