This discussion crops up every so often: "Wouldn't it be nice if a camera had a full OS behind it". Personally, I'm very pleased that my camera (a Nikon D850) boots instantly (approx 0.2 seconds) and has a shutter lag of 0.05 seconds (when pre-focused). It essentially never unexpectedly hangs when I need to take a shot. For my preferred subjects (wildlife) a consistently instant response is far more important than arbitrary functionality. If I want to share pictures or do other things, I can use the built-in wi-fi or Bluetooth to shunt pictures to my SmartPhone.

Exactly! Consider how incredibly slow it is to take a photo on a phone. And how short the battery life is. And how few capabilities the phone photo editing has compared to desktop photo processing where CPU, RAM and battery life are not constraints. Why would I ever want any of that in a DSLR? A DSLR can go from sitting on the shelf to having taken a focused photo in less than a second. The battery life is measured in weeks (unless using built-in flash). No comparison how much better experience it is.

  The reason phones have those issues is because they have to compensate. I have a FF camera that runs android, and it lasts on standby for a month, takes a picture in 0.023 seconds, and so on. It's just that phone cameras are not optimized for latency and phones in general are not designed to be cameras.

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.

    Using test equipment, I'd imagine the way to do it would be to sync a microphone and a logic analyzer and then short the shutter button. For the Sony A7 Mark I it's around 0.023 seconds : https://www.imaging-resource.com/PRODS/sony-a7/sony-a7A6.HTM https://www.imaging-resource.com/PRODS/sony-a7/sony-a7A6.HTM Granted, it's not "no shutter lag", but 2.3ms might as well not exist.
