Never heard of any camera being able to switch focal lengths within 1/60 of a second, which is what you would be asking.
If you are looking to do it with only one camera here are the tricks I have used when found myself with a one camera shoot and someone talking.
1. Zoom so slow the audience doesn’t notice it.
2. Wait for a moment when the speaker is pausing for a drink of water, turn of page, or dramatic pause, then change your zoom fast and edit that few seconds out.
3. Find a place where the speaker is repeating himself. Some do it a lot. Then zoom there. During editing, cut out the sentence or two. He won’t notice and the audience will be glad.john

You do that kind of stuff in the editor.
Before shooting, sync the cameras.
While shooting you zoom in reframe, and keep shooting.
Use an editor that allows multicam, bring in the two camera angles, sync up, choose which camera to avoid the zoom.
I recommend Sony Vegas Pro as an editor.

What is it you are trying to accomplish that you are looking at those external recording units for?

You will be happier with the fmu128 and probably use it as primary, and if you want backups, use the sd cards as backups
What I would do is to download the update for the nx5u firmware and then read the instructions, and go through the steps of trying to update it. The software will compare tell you the current firmware and then tell you the new firmware and if they are the same, will tell you.

Thanks for your thanks.
Congratulations.
John
PS. The other settings I gave you, ie the white balance, are so you could get the colors consistent if you do a highlight of a team in different rinks. The shutter speed is to make slow motion, or to grab a picture off the video better.

It might be. If you can repeat the experiment, you may have found the ghost.
However, If you format the sd cards on your camera and only use a part of it, you should be able to keep using it on the same camera later without reformatting it again.
I just know I have had problems with SD cards in general, such as working in one type of camera and not another type of camera at the same speed. Whatever you do, test the heck out of them under different situations, before your next shoot. This includes simulating a battery failure while recording so you can feel confident what can hurt you and what doesn’t matter.

Nigel,
My recommendation is to buy the 128 gig memory unit. I have 4 nx5us for over a year and have never had a problem with the memory units.
The alternative is for you to try various brands of sd cards until you find one that works reliably. For instance, a sony brand sd card.
The only other question I can ask is did you format the sd cards in the camera itself?

Hi Jerry,
Here is what I have discovered about shooting hockey.
1. The puck is fast and small.
2. The lights are terrible, usually high pressure sodium arc.
3. The most coveted clip is full body shot of the player slapping the stick against the puck and the camera follows the puck into the net, bulging against the back of the net, then dropping, all played back in slow motion.There are conflicting camera requirements, and I have experimented a lot. In order to see the puck while it moves, you want to have a high shutter speed, like say 1/400 of a second.
In order to work in the dimly lit rink, you want to have a slow shutter speed. In order to get a close shot, you want to zoom in. In order to make sure your player with the puck is in focus, you want a narrow apperture for larger depth of field.
What I do is the following:
Set the shutter speed to a manual 1/180 of a second. The lights actually turn on and off 60 times a second, and if you are not on a muliple of that, you will see the lights go bright, then dim on the video over a 4 second cycle.Then I make aperature, focus automatic. Make sure the nd filters are off.
Then I tighten in on a “white” section of ice before the zamboni clears it from the previous game. I press the button to memorize that setting as white in the white balance. Since the overhead lights range from yellow to green, this makes them look fairly the same whiteness.
Next I set the AE or AS, that is automatic exposure adjustment, to be plus 2. This is because the camera light sensor sees all the white relections from the ice and the boards, and actually makes the tries to optimize on them, making the players and puck too dark. Alternatively, sometimes I will actually watch the settings in the camera following a player tightly during warm up, and just put the aperature into manual at that setting. This again is because the interest is the player and puck, not the white boards or ice.
If you need more information on what I do, let me know.

Steve,
The zoom on these various from about 10 to 100%. You will have to guess based on me standing next to a soccer field midfield line.
Someone on this forum earlier did a study of outdoor shots with the nx5U and determined that the chromatic aberation was best if the lens aperature was opened more than 5.6 and worse as it got toward f11.

Stephen,
Here are some frame grabs from soccer games.
I chose ones that are shot against the sun, and have some sky in them.They were shot in 1920x 1080 x 60i. ND1 filter on. Approximately 1/180th of a second. Aprox 5.6 f stop, -3db gain.
I hope this is helpful to you.
