Earlier quoted context omitted.
Your camera doesn't actually boot in 0.2 seconds, it just wakes up from sleep. My Sony runs Android and never hangs nor has an shutter lag. Instant response in everything. It can be done.
How did you measure the shutter lag? .05s is like a couple hummingbird wing flaps.

I looked at the camera specs online.
