51 point 3D tracking on the D3 is superb - and I'm pretty sure it's the same as on the D300. Pick up the subject in the centre point and it sticks with it flawlessly - if it doesn't - you don't have the camera set up properly. I use it 99% of the time!
Same here. I've used it on the D3 and D300. Worked ok, but I must admit I don't use it much. Haven't even tried it on the D3s yet.
Kev.
Chaps (or anyone else), would you care to explain a few of the settings you use. It'd be good to establish if the folk not getting along with this system, just haven't managed to get it set up in a way that would be good for them.
I'm mainly thinking about which Dynamic AF Area you use (maybe you change from time to time), and what you have ' Focus tracking with lock-on' set to, considering that switching it to 'off', increases the responsiveness of Dynamic AF, but may then cause problems if it's likely that something may briefly block your view.
Also, what situations are you 100% confident in using the system, and when would you turn it off?
I think with some extra info, we could make sure the TP D300 users fully understand how to use this system, and the world will be a much better place.
I've not yet used the system in anger, and I'm dying to use it for my Mountain Bike photography, as previously I've always pre-focused on the spot where I want to capture the rider, and then switched to manual.
But I have now set up my camera to use the AF-ON button, switched servo mode to continuos, and enabled 3D-Tracking, set 'Focus tracking with lock-on' to OFF, and with a bit of luck, that's how I'll be leaving it. (Although D300 digitutor does recommend the 9point AF Area for the mountain biking stuff - we'll see...)
I hope users can take the time to explain the points I've raised.
Cheers
