The NT-4 will definitely be quieter, and also more sensitive. That's how it gains an extra 8db of signal to noise ratio, by winning in both those categories. 6db is a doubling, so this is a significant advantage of the Rode.
It's true that the high frequency response of the Rode appears to roll off more significantly than the AT, but if this high frequency content is lost in the hiss with the AT or if your camera can't effectively record that high anyway, I'd go with the Rode.
The main complaint with the Rode would be the weight and shockmounting it to a camera. I have used an NT-3 in an AT8415 mount on a static boom. It's not super secure and I'd be very careful about active booming, but for horizontal mounting on a camera it should be fine.
Neither mic is that easy to wind protect unless you buy something specifically made for that mic. It can be done with off the shelf materials, but it takes some experimentation due to their larger wider heads.

I've used the Rode NT4 mounted on my camera. In quality terms it's probably a good match for the audio spec of your camera. I use an AT8415 Shockmount, with a flash shoe adaptor. It does make the camera very top heavy, but it is usable. Rycote make a windgag that fits the NT4.
I chose the Rode, instead of the AT825 or AT835, because there were favourable reviews by musicians using it to record music. (Look at the Rode site).

I got the Rode because I wanted it for quiet
situations, where high sensitivity would be required.
It is *very* sensitive to wind noise. The foam windscreen
that it comes with is nowhere near effective in the wind.
Patrick, have you used that Rycote? Any help in
locating which windgag, such as model name/number?
Anyone had any luck making a homemade furry, or
is special acoustic material required?

Dave,
The Rycote windgag is called the "Mini windjammer for the Rode NT4". It cost me 35 UK pounds.
I have found it reasonable for ordinary outdoor use, ie. light wind. It is not effective if it is really windy.

Don't drive yourself nots over specs and other peoples opinions. Listen to the mics yourself.

Many people will cavalierly throw out a mic that cost 2 or 3 times the mics we started discussing.

I really don't think the term HiFi belongs in this discussion. HiFi is more reflective of the whole audio chain than just a microphone.

I for one know that Dave listens to mics with his ears rather than his budget or the microphone specification.

And what peaves me, Beas, is half the time people
throw out their opinions, they haven't even worked
with the mic they're talking about.
They've read somewhere on RAMPS, or
wherever, so it must be true.
Best off to listen to those who've actually
used a mic in question.
Ralf, specs really don't tell you how a mic *sounds*.
You need to listen for yourself before making a
final decision. More important in a mic choice than
specs is *character*. They all have their own.
And just like a leopard doesn't change its spots,
a mic brings its character everywhere it goes.

At least now I know a little bit better what to listen to when trying mics (self noise and recording of quiet sounds, freq. response, spatial impact, sensitivity i.e. sensitivity to wind and handling, intelligibility of speech, overall feel...) so there is a better chance of a succesfull and informative comparison now.

When starting this thread I hardly knew about frequency response and believed that shotguns were allways the best choise (no comments on that, please - I've read a lot of those discussions).

I have learned that a stereo 2x cardioid mic might be better for my specific purposes (including stereo ambience for some effects...) and that in addition to the frequency and polar responses I also have to consider the signal to noise ratio and the overall "feel" of the sound... I really did not pay attention to S/N ratio before I read about it here.

I also know now that both the AT825 and Rode NT4 are much better mics that the Sony default and that NT4 is more sensitive and quiet and thus more capable of recording quiet sounds cleanly. The AT825, on the other hand, records high freq. at a higher relative volume, which could be usefull (with my poor camcorder) if it sounds good too and if those freqs. can be heard above the mic noise. Sensitivity might be bad, too, when mounted on a camera...

Some people like the stereo image that the NT4 gives. It has at least been used to record concerts in stereo. That does not tell anything about how natural stereo image it gives in a forest, though, where "ambient sounds" is a something completely different than in a concert hall. Isn't that true?

There seems to be no quick path to follow. I must test them all...

This is a good starting point for a mic listening tour. I have some assumptions that I can test and try to verify...

Without the good advice here I would probably have ordered a mic from a web shop without listening to it first. Now I think it is best to head for the shops next week and to try a few myself...

vp88

If You are not looking for a shotgun mic and You'll not put it on Your pdx10 but just on a stand near the camera... then Shure vp88 is also a very very good stereo mic. I'm using it myself for audio recordings. Tested already in very different situations. Early and liturgical music recordings, meetings and conferences and so on. It's working with phantom and also with batteries.

Is there any particular reason for not mounting the Shure on a camera (besides the fact that a camcorder is a relly poor place for a mic generally)?

Is it too big or too heavy for camera-mount use? Hard to find a shock mount that works? Or maybe just too sensitive? Money wasted?

- I hope to test all three in a week or two... If I manage to do that then I'll post my experiences -

So, Ralf, did you ever test them?

I haven't had a chance to test them yet. Working 5 days a week, shop open 5 days a week... But I'll definitely test when I have time to. I'll let you know then.

There is no hurry, as you can see. I still have two months time before a major event where I would need stereo...

Meanwhile, I have been thinking about the alternative of getting a separate 8-mic... That would be a quite flexible setup, but I'm a bit uncertain as to how well such setups would work on a camera. The figure eight mic might pick up too much camera noise (I don't know yet)... Maybe that can be fixed in M-S stereo matrixing in post, though.

Dual mic M-S stereo would be nice because for me:

- it might become cheaper, afterall (keeping the side mic and changing the mid mics)

- a dual mic M-S stereo setup would improve the mono quality too (getting a new mono mic...) I have to get a better shotgun and a cardioid or stereo anyway.

- it would also enable stereo recording with at least some kind of control over the width of the stereo image (better than with fixed X/Y stereo). Note: speaking of stereo image width to avoid the bad Z-word ;)

- it would be automatically mono-compatible.

- it would be possible to add a controlled amount of stereo ambience to situations where a shotgun is needed - or keep it strictly directional and mono - and a better stereo localization would be achieved with a cardioid mic.

This would be a three mic setup. A shotgun, a cardioid and 8-mic... A bit expensive, but cheaper than buying an X/Y mic that might not quite do the job...

Oh, It'll be a long listening session, when I have time for it...

Unfortunately separate figure of 8 microphones, e.g Ambient Emesser, Sennheiser MK30, Schoeps MK8, are expensive.
But then you never need to upgrade a top quality mic.

The Schoeps range is modular so you could buy 2 power modules, and 3 capsules (figure of 8, cardioid and hypercardioid).

Alternatively, you might be able to compromise with just the MK8 and MK41 (hypercardioid). Instead of a shotgun use the MK41, Instead of a cardioid use the MK41 combined with the MK8. This will given you a wider polar pattern than a mono cardioid.

The Schoeps microphones are very light. I have used them in a stereo pair mounted my DVX100 in an Audio Technica AT8415 shockmount.

I've been thinking of getting another Schoeps preamp and the figure8 capsule. manfred Klemme at K Tek makes a piggyback mic mount so the MK4 or 41 can be mounted with the fig8 in the same standard rycote windshield.

Bryan,
Definitely don't use the Rycote MS mounting clips in a mono Rycote windshield. You have to use very short rubber bands and the whole suspension becomes too stiff.

I very clearly posted that I won't be using rycote shock mounts. K-tek have a piggy back arrangement much the same as the Emesser by Ambient . I have 2 K-Tek mounts and they're great. Have a look at the standard mounts. Any of them can be adapted for any blimp system.http://www.mklemme.com/pole/home.html

On the Schoeps i'm using the very soft mounts that were developed for the Sanken CS-1. Even with the Baby Ball Gag it works great
