I was just thinking, especially for Steve, maybe he knows already, but I just got a new mirrorless panasonic recently. I had always used larger dslrs in the past.
The mirrorless has an electronic shutter option and it is awesome. I was shooting birds that were coming very close to me on our patio here, and noticed the focus beep would scare them off. I went into silent mode, which auto triggers the electronic shutter. It makes no noise when i shoot a photo, which is just awesome.
I just thought this would be a great benefit for a pool shoot. My gx85 is a micro 4/3 camera, so not ideal for low light poolroom work, but i bet most new mirrorless like the sony a7 series will have this option... if you can afford them :heh
