>>3690020I'm not super familiar with how the electric shutter works but at the top of my head, I think the biggest advantage would be that it eliminate vibrations.
As for the shutter / mirror wear, like
>>3690027 says, I think it would be minimal. At least when you're doing tracked shots, 1 shot every 30sec
which can go as high as 5min, it's pretty minimal.
I'm sure I average more shots per minute walking around during the day and taking pictures. And this completely goes out the window as soon as you start doing anykind of fast photography like sports or birds in flight.
with this one, I was out for probably an hour, and I took probably 50 shots max.
