Hello and happy new year Wink

A contact ( thanks simbon4o ) on flickr advice me to use both electronic and mechanical curtains with a speed faster than 1/1000.
I test with both curtain and with only electronic curtain and the bokey changed.

her some pictures ( all the parameters are the same, i only active first electronic shutter on my A7)

Etonnant!
I shall try that.
With high speeds and tele , you can have an uneven exposure . I don't remember in which case , with two or one shutter.

Looks like, in both cases, the mechanical shutter leads to a visibly brighter exposure. That changes the bokeh as highlights show a stronger glow and dark regions are brightened.

But just to clarfiy - it doesn't matter for bokeh whether you use an electronic or a mechanical shutter. The pictures would look the same if the exposure was identical!
