This was my problem another member mentions some time ago.

I have a Nikon D800 and with using A 24-70mm lens when trying to video all I got was a lot of refocusing noise from the lens area. This is because the inbuilt mic. is right along side the offending lens.

the 3 holes are for intrnl mic.

So ok I thought try an extrn mic mounted on the hotshoe. So I mounted my Sennheiser MK400 mic and tried again



No good still too close to the lens, so head scratching starts. I have an idea , get one of those small extn mounts but still too close see below picture.



Now for some serious head scratching and started searching the web for a long extn bar that I could use, but they are all twin mounts which i didn't want so there has to be another solution. What did i have already so i didn't have to spend any money? Ah this came to mind. My pistol grip might just work so I put all three together




Needed 3 washers to tighten up the grip to mic as packing

and got as far as this





Yes I know it looks silly but has not cost me anything I already had every thing. Cost wise around £10 in total for the grip and extender as i said already had. At least I have got the mic away from the lens noise hopefully
.
. AS it is now dark I will have to try it out tomorrow, but it may just work. What do members think about it?

It's a great idea , if it works. Hope so.(y)
 
Surely some of the noise is going to transfer simply because it's physically connected.

If that would still be the case, I'm thinking that perhaps a rubber tap washer instead of metal washers might solve that.
 
The mic is on rubber supports already



So vibration is not the problem it is sheer noise (sound) it is picking up. Those washers are dead tight anyway. Good thought though thank you.

I have asked Nikon about this and awaiting a reply

My camcorder is designed for videos and a far better option

No focus zoom noise at all.

Seems to me Nikon have concentrated too much on tweaking how a camera performs with photos and totally forgotten about the sound side and thrown it in as an after thought.

If Panasonic can make a camera/lens with smooth focus I can't see why Nikon can't

I'm no expert, but as I started trying to take decent pictures I realised controlling the light was crucial and needed seperating from the camera

And as soon as I wanted to shoot video, i felt the same about sound.

An iPhone using its own headset mic is a better 'sound recorder' than my camera.

Nah Nikon just know that people who are shooting decent video with an SLR are going to be using manual focus. Also, there's a good chance they will have their microphones off camera.

USM lenses are pretty quiet anyway, should be fine if you had a half decent shotgun mic on camera and wanted to use AF for some reason.

About the light that is why I got a light meter to see what difference it made against the camera doing it. With the sound issue it i got really over it by using an extn mic lead which worked but not ideal as the mic had to be that much further from the camera,so really it needed someone to hold the mic
 
DSLRs arent really made for video AF as already said, mirrorless cameras AF system reads directly off the sensor so the video AF is way better (Panny, Sony, Oly etc etc). Until they put phase detect AF on all DSLR sensors you wont get decent video AF or the lenses to go with that. I think its only the Canon 70D that has that technology currently, they also have video specific lenses.

Thanks

I was doing just a tryout to see how bad the noise was. I shall stick to my camcorder and just have to carry around two cameras as usual
 
Had reply from Nikon


Thank you for your email.
I understand your point and I have to agree that the sound of the AF motor (in case of many, but not all lenses) is recorded in the video, even if a hotshoe-mounted microphone is being used. A "hotshoe extension" would indeed be an effective and very simple solution to this.
I have forwarded your suggestion to the appropriate department for consideration. Unfortunately due the number of similar communications we receive, we cannot offer a response to each suggestion individually.

The Sennheiser MK400 mic at around the £150 mark I would call a half decent mic if not excellent. You did not listen to my second video of the train then, you would be very hard pushed to get a better sound reproduction and the distance it picks up sound from. That was with this mic on my camcorder.

You again say about people using manual focus but you miss the point of focusing hand held NOT on a tripod which obviously will be a lot easier.

I defy anyone to manually focus handheld and not have camera shake especially if panning
If you look at videos most are shot with the subject coming/going to or from the camera. Very few are panning and if they are they are using a tripod

Almost all professional or serious amateur film is shot with manual focus. A lot of it is shot handheld. Higher level stuff will have a focus puller of course, but there's plenty out there with a single camera op doing it all themselves, especially the kind of stuff that's shot with a DSLR. Practice, and either a simple shoulder stock, or eye piece is the way to go if doing it yourself.
