cgbachSony A9
Anyone have or play with a Sony A9? It appears that this camera has a maximum shutter speed of 1/32,000 sec., which is pretty amazing. For me it would only be usable if the shutter could be triggered electronically so that it could be used to capture images of fast moving objects, i.e. bullets etc. Are there any other cameras out there that are faster that don't cost north of 50k$?

The camera only takes the photo, and it has noting to do with the having an electronic or mechanical shutter. Take a look at this:

cgbachThat is one way to do it but it takes a very controlled environment. It would be nice to be able to this kind of work with natural light outdoors.

It can be done outside, too. But you would need to have the sensors and the computer that trigger the camera. For example, it does not matter how fast the camera's shutter speed is, because there is no way for one to press the shutter button fractions of a second before the bullet reaches the front of the camera where the lens is facing. The whole thing is similar to where the two sensors in a chronograph do.
The front sensor and computer trigger the camera milliseconds ahead of the bullet. So by the time the bullet is less than half-way from the first to the second sensor, the camera is already taking a photo.

SaeedOr you can spend several hundred thousand dollars and get a real high speed camera.
One that can shoot several thousands frames a second
