I took some tests of SAS on the NX500. It looked like it worked pretty well. Here are some test shots (note: I'm definitely not athletic and yes, I definitely need more exercise :) )

Baseball shot mode:

Jump shot mode:

Trap shot mode (I put the vertical line a little bit ahead of the ball):

Overall, I think SAS worked better than I expected. I wish it had raw and could take a continuous burst, but it is still usable. Looking forward to my kid's soccer season :)

Here is a more detailed description of the tests I did: http://betterfamilyphotos.blogspot.com/2015/04/testing-nx500s-samsung-auto-shot-sas.html

Are you able to do a golf-swing test? I'm not sure how to be sure the ball triggers and not the clubhead on backswing.. but both would be cool too :-) thanks!

It's good to see that the other sports do what's expected.

OK, I'll give it a shot ;)
 
Very nice work. I've been wondering what application I might make of these capabilities. I love this line you wrote: "It's a feature that no one has asked for."
 
Help me understand the distinction between baseball and trap - they both snap when "a target reaches a line", don't they? Your write up and illustrations are superb.

No Raw?? Samsung is putting strange limitations into their cameras. I can see no good reasons to allow only jpg on these modes.
But maybe it will come with one of the next fw releases... in the next months... years... or whatever
 
Thanks! I think Trap Shot has many potential applications. Jump Shot can also be used for many things such as martial arts (e.g. flying kick).

Yes that's an accurate observation. They are both very similar. The functional difference is that the vertical line can be moved across a wider range -- anywhere from one edge of the screen to the middle of the screen. Baseball has a narrower range of movement for the vertical line. I think the reason for this is that a baseball moves much more quickly than most objects, therefore the camera needs adequate time to spot the baseball and calculate its location, that's why in Baseball mode, they don't allow you to move the vertical line more than about 1/4th of the frame from the edge (as opposed to up to half for Trap Shot).

Best regards,

Mic
 
I know, it's sad isn't it. My speculation is that the processor is being used almost entirely to monitor the scene and make the necessary calculations... ??

Does anyone have an NX1 they can test? Maybe that has a raw mode?

Best regards,
Mic
 
I already donated my golf clubs so I tried it with a baseball bat held like a golf club. The NX500's SAS could not detect it. Even a chip shot type of movement could not be detected. I think maybe SAS is designed for a more or less straight movement, not a curving one.
 
You may be right about the curving motion. I tried using the trap shot mode on my NX1 while chopping wood. I fiddled around with it for half an hour with no good results. Burst mode or 4K frame caps worked fine.
 
I have heard that Samsung might create a SAS mode for golf. But in the meantime, I agree, burst mode or 4k video frame grab would probably the best alternatives for golf shots.

The 2 second 30 shot burst @ 15fps is excellent for golf swings. Most decent golf swings take about 2 seconds; ~1 sec for a backswing - 1/3 sec for the downswing - 2/3 sec impact to the finish. I've used it a number of times with the NX300 and the NX500 looks to be the same. It's helpful if you can match the beginning of the swing to the shutter release and use a very fast shutter speed.

It's a great tool to use - try it both facing the golfer and looking down the target line.

Yes thanks from me also, sounds like a very good option. For working alone video would probably be best, so I can narrate good & poor shots to best pick apart swing issues. :-|
