The D700 has got 14-bit RAW NEF which is supposed to have better dynamic range. I think you should check out the D700 test photo thread for more. I posted some amateur HDRi there.
Hi, I was actually trying to ask how is the Dynamic range as compared to S5pro.

14-bit per se does not imply higher dynamic range, just smoother gradations for better processing headroom.
I wonder why people worry about so much dynamic range. A modern DSLR has more than enough DR for most applications, if you need more DR, just take another shot with a diff exposure and do HDR.

I dunno man, but that's what the manual says "14 bit bla bla bla better dynamic range" :dunno:
dynamic range (DR) should be a factor of the signal to noise ratio, fill factor of the sensor, and signal processing, rather than the bit depth...
as I explained somewhere else in the forum, imagine you have a S$1 and US$1... the US$1 will have more monetary value than the S$1 even though the numerical value is the same (i.e. both are 1)... now imagine the S$1 is divided into 10S¢ coins... you would have 10x10S¢ coins... but if you divided into 1S¢ coins you would have 100x1S¢ coins... if you do the same for US$1, you would have 10x10US¢ and 100x1US¢ coins...
now to tie it all together... DR is like how wide a range of brightness values you can record... a wider dynamic range would be able to record a greater range of values from dark to bright, and vice versa... signal to noise ratio of the sensor affects DR by determining what is the darkest value that may be recorded, past which the sensor cannot determine if what is captured is noise or part of the image... light fill factor of the sensor determines what's the brightest values that may be recorded, past which only perfect whiteness will be recorded ... and signal processing determines at what values the camera will actually stop the processing for recording brightest or darkest values, as well as what values to assign what levels of brightness... as can be seen here, cannot really tell the DR of a camera by looking at any one value, and certainly not from the specs given by manufacturers... only real way for the consumer is to try the camera out, or believe what the manufacturers' marketing and PR materials tell you...
taking the $1 analogy, the DR can be said to be like the $1, where there are $1 with more value (US$1) and $1 with less value (S$1)... bit depth (i.e. how many bits, whether 8bit, 12bit, 14bit, etc.) on the other hand is like how finely you divide the $1... so you can divide your $1 into 10¢ or 1¢... whether its US$1 or S$1, in the first form of division, you would still get 10 coins, and in the second form of division you would still get 100 coins, just that each of the coins in their respective currency will still have different values as well... so high bit depth is like dividing the $1 into coins of smaller value, where you would get a larger number of coins and the value of $1 is divided more finely, whereas a low bit depth is like dividing the $1 value with larger coins and the $1 is divided less finely... but the absolute value of the $1, for the case of currency, or the DR, in the case of an image, is still the same whether its divided finely or not...
these explanations are of course gross simplifications...
sorry for this massive OT... ;p

I found something minor, but important to me.. .. Unlike D300, D700 cannot set to 'mass storage'. Any uploading, e.g. firmware would mean that I've to remove the CF, save the file onto the CF and put it back. With D300, I can simply plug the cam to my computer and do everything
anybody here has used the d700 with 85mm f1.4 in a wedding? We covered a wedding last week and there were times that the d700 is not focusing properly. Does anyone here had experience the same case?
to TS.
sorry to put my question here. i dun know if i should create a new topic.

when I plug it in, it detects as camera but iirc I can copy and move files :dunno: let me confirm again. But I think this issue can be corrected by the next firmware upgrades

It is blooming according to the Nikon engineers and not banding.
If you are shooting @ high ISO and the subject is almost pitch dark, but on the other hand you got some very bright illuminating object (like street lamps), it will cause blooming effect.
As long as you keep this point in mind, the blooming can be avoided just like lens flare once you know how to avoid it.

I've got no problem with focusing on the 85 F1.4. Even in extreme low light the lens can still focus.
What is the details of the problem you faced? AF hunting or lens not delivering the sharpness?
If it is the later, you may want to configure the type of AF and the duration of the AF. The 85 F1.4 have issue with AF duration.
AF hunting... I was using a single point focus. The wedding was in the morning and there are time that it doesn't focus so I have to do half press around 3-4 times until I got the focus. Even though I encounter this issue I was still able to take nice photos from the wedding.

hey. i encountered the same problem as u when i tried the camera last weekend. it was one of the main factors that will deter me from changing to nikon.
For 2+k more, get D3 lah..

haha. see can get any discount or not first. :sweat:
Bro, are you using PC? I have no problems downloading directly to my Mac.
