Impressions Of NX5U After Two Weeks
 
I use the NX5U as a Stringer gathering local news events mostly (95%) at night. The NX5U replaces a DVX100B (now a back up rig) so this is what my impressions are based on.

The way I use this camera is generally in low light field night time ENG.

Pros

Great Low Light

Manual Controls

Simultaneous Dual Format Recording (w/external H/D)

External Stock Mic

LCD Touch Screen

Expanded Focus

SDI-Out


Cons

Low Light Auto Focus

AVCHD With FCP (short term problem)


Wish List

Being able to xfer files both ways between media types

Ability to stamp (place bug) on video files

Dear John,

What do you think about the autofocus speed and accuracy of NX5 at normal light ?

John Mulvihill April 7th, 2010 09:38 AM

Here I am sitting in a parking lot at 0430 hrs waiting for something tragic to happen (by the way it did, one more ATM theft). Almost all of my shooting is at night. Here is a post I did on you tube that if it weren't for the eye candy this would have never made it to edit. I was using the LCD while shooting and it looked sharp as can be but finished product was not.

The jury is still out on a final decision regarding the NX5U auto focus. One thing I will tell you is that I am glad that the expanded focus button is next to my index finger.

Regards,

John

I just don't like the Auto Focus option on any camera, and the button to get a quick focus isn't very quick on the NX5U (or most cameras I've used). Interesting footage.

John,

Thank you for the answer.

I warned you it wasn't very good. I think that was the second time I hit the record button in the field. The whole point of showing that video was the fact that is was very soft while the view finder/LCD did not show just how soft it was. I am embarrassed by the quality. Very well could have been operator error. I was focused on those two asian girls to bad the camera wasn't.

John,

It's tough to get focus in dark situations no matter what camera, though I'm sure the EX1 is slightly easier with its 1/2" sensors.

How is its low light performance compered to DVX100? Have you tried them side by side with open iris and zero gain?
Thanks.

Heath McKnight April 7th, 2010 05:09 PM

Stas,

I haven't, but back in late 2004, my friend/colleague Jon Fordham and I did a side-by-side with the DVX100a and the FX1, and if I'm not mistaken, the FX1 was wide open (0 dB gain) and the DVX100a was at around F 3.4 or something. Here's that review:

http://www.dvinfo.net/forum/sony-hvr...x1-review.html

This is because there are over a million small pixels on three 1/3" CCDs, whereas the DVX100a featured just a few hundred thousand larger pixels on three 1/3" CCDs, giving it an advantage as far as light is concerned.

Thanks Heath,
that sounds about right to me (a couple of F-stops difference DVX100 vs FX1).

I've always been sceptical about HD cameras low light performance, so I'm wondering if anyone did a real test of the two using DVX100 as some sort of a reference, just to give me an idea of what it is, preferably in F-stops.
Looking for an upgrade for a DVX100 too.

John:

One last question before we say that the autofocus is bad. May I ask you to look at these 2 videos, please ? They are not my videos. I would like to know that based on your experience with nx5, do you think that nx5 can make such videos with autofocus ?

Thank you.

I can tell you without a comparison. I shot a fatal motorcycle accident two nights ago under mercury vapor lights. IMO the worst of all video light. The performence of the NX5U is by far supeior over the DVX100B. With the panny I have to run 200 watts of on board (2 100w Frezzi mini fills) lighting. In a comparison what is important to me is not a side by side same settings but what the setting are to make usable footage and how good is it. I can tell you hands down the Sony is better. Remember I sometimes have to shoot not just in low light but almost no light.

If it's not to busy tonight I will do some comparisons using same setting and usable footage settings. I have to make a disclaimer that I know the panny like the back of my hand in low light while I'm still learning the ability of the Sony.

You can see some footage on my You Tube page. YouTube - SanDiegoMedia's Channel
I think I've only posted two vids so far using the sony.

Without a dought. My shooting is different then most because sometimes the question is action shot lower quality or good quality but no action. At times I have no set up or adjustment time when I arrive at a scene.

Heath, The panny did a good job. It seemed not to lock into a almost in focus mode where the Sony does. I have been proceeding with great caution until I get up to speed on the Sony. Besides that it's a 4 grand camera. can you really expect to shoot Ben Hur at night?

Thanks,

John

John,

Which Panasonic?
