  1. Yes
I was visiting a Photography Forum elsewhere and I read a comment a user posted about not liking Pre-Capture because they do not like AI.

Isn't pre-capture just a better version of 'Spray and Pray' or pulling an image from a video...am I missing something here?
 
Yeah as I understand it, pre-capture has legit nothing to do with AI. It's just a constantly cycling buffer that allows you/the camera to retain the frames just prior to fully depressing the shutter button.

As described above, it constantly records and overwrites the images whilst half pressing the shutter button until you fully depress the shutter button and it then saves the last 0.5 of a second's worth of images. That's 15 images on the R52 at full high speed fps providing a high enough shutter speed is also set. It doesn't seem like a big advantage but in real terms it can capture something that you might otherwise miss. I had a garden project photographing sibling Foxes and they would suddenly leap in to a fight and the buffer would have been able to catch what my reactions missed . The spray and pray method just doesn't work in those scenarios as you would fill the buffer before the action started.
The downside is that it appears to eat battery power which is one reason they have produced a new one for the R52.
You can also use the feature for video and the time pre recorded can be seat at either 3 or 5 seconds. I bet that really chews battery power though.

You are absolutely right. I do not not see the AI anywhere in Pre-Capture. Pre-Capture adds few seconds of pictures before you hit the shutter button to the end.

Edit: For the record, I did not like the implementation of it in the R7 and never used. I think that now in the R5 Mk2 they changed a little bit and now it's not a huge file that you can review in your camera and select the picture that you like, but still, I do not like it:
1- Eats your battery
2- It creates more pictures for me to check.
3- I love the excitement of hunting for the moment and the frustration of not getting your picture because you were too slow. No using Pre-Capture keeps me sharp ;-)
 
I wouldn't put it past some craven marketer to couch pre-capture in AI terms though, even though it's not related in any way. Maybe the poster who prompted this thread was misled in the first place by some deceptive word salad. I can picture it now: "This new camera leverages the power of AI to intelligently improve the results of your shutter button reaction time by, amazingly enough, reconstructing the split second before your brain could tell your finger to trigger your camera shutter. The advanced machine learning outperforms your frail human body by up to one second, depending upon your camera's frame rate."

Marketing people will say anything is AI to increase sales! Eating your battery by constantly capturing pictures and keep them in the buffer to just saving them when you full press the shutter button is not AI in any form or shape! At least in my book. The only thing that I can say is that it was a good idea from whoever thought about it with some cons battery wise.
 
Fifteen additional frames (because I use pre-continuous shooting for wildlife): for me that is not a shock/horror scenario when culling unwanted photos.
