3. Aperture control in movie mode- I know there is no way to overcome this other than a firmware update (that too subjected to hardware design). Is there any hope on Firmware side?

The only hope is for an automatic mirror flap cycle to set a new aperture. You will not get live camera control of the aperture without some blackout time during the mirror flap.

However, the good news is that you can use any of a wide variety of very excellent Nikon and 3rd party lenses with a manual aperture control ring. You may even want to get a lens where the aperture ring is stepless to allow for a smooth transition between aperture settings.

How exactly did you come with such a false analyse ?

I think his analysis is very probably right. There is a difference in the way the stop down mechanism works between the top end and lower end cameras. The D800 has a separate motor for the stop down mechanism. The D7000 dual purposes the mirror motor, so that motor closes the diaphragm then flips the mirror (the preview function stops the motor before the mirror flips). Therefore the diaphragm can't be adjusted from the camera with the mirror up. If the D600 is built like the D7000 it physically can't operate the diaphragm in LV or video. It's one of the prices you pay for the cheaper camera.

This has been said earlier but nothing proves it, especially knowing that the aperture function does actually work in live view in still photo mode. Moreover Nikon sent us an email announcing that they will actually fix this by providing a D600 firmware update. This also has nothing to do with pricing but with marketing strategy. Nikon D600 dont sell actually as well as they should (I talked to 3 different sellers about the matter) and by unlocking those functions, they probably will sell more cameras. Also, regarding pricing, all canon and Sony cameras offer this function in low end cameras.

No, nothing does prove it, it is based on the assumption that the D600 mech is like the D7000 mech, so far as aperture actuation goes. While likely, it may not be the case. Still, you call his analysis 'false', which is going too far, what you mean is 'not necessarily right'.

I first called it not necessarily right (months ago) but by using simple logic (live aperture works fully in still mode) and knowing that it is fixable by firmware, I call it false.

I'm not sure what you mean by "live aperture works fully in still mode." Yes, the aperture setting can be changed while in photo mode, but the new aperture setting does not physically take effect until after a mirror flap actuation (as, for instance, right before shutter release).

You can see this behavior in the following video at 11m40s: http://www.youtube.com/watch?v=qk5qOrqcbIQ&feature=youtu.be&t=11m40s

Notice how the aperture setting does not affect the depth of field in live view until after the photo is taken.

You and Bob2n are right on this one, I just double checked on my D600, now if Nikon claims they are able to fix it with a firmware update it means 2 things : 1) they are lying and will never be able to fix this issue. 2) they can do it but purposely brick their cameras. (the D800 live view aperture works with live update).

There is another possibility, which is that the D600 mech includes the extra motor, but that the relevant parts of the firmware were just lifted from the D7000, without the programmers realising that they had the ability to make an instant change.

BTW, nice to see we have some people on this forum big enough to admit that they got it wrong.

While it may be possible that the motor is hidden somewhere, I can't find any third motor in any of the images from the iFixit teardown: http://www.ifixit.com/Teardown/Nikon+D600+Teardown/10708/3

You can see the mirror and autofocus motors at the 2 o'clock and 7 o'clock positions around the lens mount in this image http://guide-images.ifixit.net/igi/FMEdN2ZVNYAmEOye.huge

For comparison, the third motor of the D800 can be seen (the smaller of the two metal barrel objects) in the picture under the heading "High-precision sequential control mechanism": http://imaging.nikon.com/lineup/dslr/d800/features03.htm
