Re: AF speed D700 slower than D3? how come ?

good suggestion,

unforturnely, I only has limited lens, I do not have 2 x 28-70 afs, if I use difference lens, it will not be sicentify...

will try out once I willing to spend on 24-70 G lens. As AF speed matter, nikkor 28-70 afs ED & 24-70 G N should be same....

Do you have both cameras? Could you do a test.
Put a lens cap on and switch the AF to CAF.
Also, please turn off the AF assist illumination for the 700.

See if the lens searches from near to infinity and back faster on the D3. I suspect it might because the D3 is operating on a higher voltage.

Please let us know. I suspect there might be a difference but imperceptible for most photogs.

I owned/used D3 since April 2008, now just brought D700 as lightweight version as for travel....

I read a lot about D3/D700 spec & comparsion review, so pitty much conclude they are same in 99%.

Start using D700 at indoor, normal / low lighting...

I use 28-70 afs lens, the same lens I have been using it with D3 for yr and half.

1st feeling;
woo...... this D700 body AF system seems slower response than D3.
I use AF 51 points dynamic mode on both body.

BUT the spec said same ; ? really ?

• 51 focus points (15 cross-type sensors)
• Multi-CAM 3500FX
• AF working range: -1 to +19 EV (ISO 100, normal temperature)
• Contrast Detect in Live View (Tripod) mode

1 more diss-like about D700;

My Capture NX 1.3.5 come from D3 box package does not read D700 raw, dam....

does that mean I have to spend extra $$ for Capture NX 2 ? but the spec said, they are the same image senior of 12 MP FX, why need difference software to read RAW .........

Does anyone has same feeling when you switching D3/D700 in use ?

OR am I over sensertive ?

many thanks
