If you're not racking up the shots on the D3S is the upgrade worth the money, £2300 is alot to throw about on upgraditis! Think of the lenses you could get!
D4 claims better A/F and useable A/F from f8 rather than f5.6, so opens up greater use of converters (though some would say that Nikon's quoted f5.6 max for existing cameras is over-cautious).
I haven't seen a lot of other claims of improvements so balanced against the above you have a D3s which has a greater battery capacity than the D4, superb low-light capability, controls that you are already used to, is probably Nikon's best DSLR to date - and around £2400 in your pocket (I haven't seen any new D4's under £4999).

Have a one year old D3s with few actuations and was thinking of upgrading to the D4. However, trade in value only around £2600 leaving a big leap up to £4900. Is the change in camera worth it? merv:bang:
The D4 is pants for video unless used in CX crop...I saw some footage of it and I wouldn't want to use it...

Its superior to the D3s in every way but that still might not be enough to justify buying it as the D3s is still superb. For me it was a d700 upgrade so it was a huge leap.
Please upgrade and sell me the D3S. As your a friend of Tony's and only up the road I am sure you can offer me a good deal on it.![]()

merv said:Hi Phil I love shooting planes, bikes and cars. If I wanted to shoot video would use a camcorder, not a D4. Mind you I suppose it is a useful add-on for the as and when situations.

I would have to ask what you are used to shooting (video)?
From what I saw it was not broadcast quality and doesn't even compare to the D7000.
It was comparable to taking a still shot wide open on something like a sigma 18-250mm, just lacking detail...
TonyNI said:how on earth mate can you say that the D4 wouldn't shoot better video than a D7K. it has a FULL FRAME 35MM sensor in it of course the video will look better!!!!! cinematic DOF etc. plus better low light ISO etc. Some people on this crack me up.
