Hi Jasem, i see your replay in gphoto gitub. Thanks so much for your excellent support
.

Yesterday i made a lot of tests with sony a7s. Here some info if can help you:

1) My old configuration where sony works and new configurations where doesn't work return me the same info about list shutterspeed with gphoto2 command:


/main/capturesettings/shutterspeed
Label: Velocità otturatore
Readonly: 0
Type: RADIO
Current: Bulb
END

the only (apparently) difference is the kstar version (2.9.7 new and 2.9.5 old) and gphoto2-libgphoto as report in forum topic. But downgrade gphoto/libgphoto as my old configuration doesn't fix the problem. So the only difference appear the kstar version….maybe some changes about bulb/shutterspeed?

2) anyway i can change shutterspeed with gphoto2 command.( gphoto2 --set-config shutterspeed=xx).

For example i can set in camera 1 second using 10/10 or 1 values.. for 30" can use 30 or 30000/1000.. ecc. to set bulb mode i can use a lot of value: 31000/1000, 40000/1000, 32, 35 ecc,...

3) Important: in my old configuration where sony works i can set the exposure in ekos pannel but in camera the setting seems to be ALWAYS bulb also for wesposure < 30 sec. Sees to change only the time of bulb exposition not the shutterspeed…..

4) in my old configuration i can take photos from sony using "Gphotoccd" or "sonydslr" in ekos setup. sometimes i have Crash warning but works anyway. in new configurations sony doesn't work (sonydslr or gphotoccd)


5) i test gphoto command for bulb mode and this works:


gphoto2 --set-config bulb=1 --wait-event=40s --set-config bulb=0 --wait-event-and-download=2s
