Reading mode: Light Dark

D3 and D300 AF modues ARE the same

Go to last post
I think most people here are forgetting that autofocus speed and accuracy is not only defined by hardware. A lot of the autofocus processing is done by software.

Nikon has been stating regularly that the firmwares in the D3 and the D300's are not yet final. Perhaps the firmware in the D3 is already more like the final firmware and therefor better tuned. That might explain the difference in speed.

As far as i am concerned any speed difference measured now is irrelevant. Test it when the camera's are released with there final firmware to get a fair comparison.
Just be patient!

I've thought about that many many times... So many speculative, opinionated, false, childish and ignorant discussions and threads that it makes me wonder how beginners can decipher anything of any kind of value.

Still, as long as I'm intrigued by all the speculations and try to read only those messages that I know come from good sources I will continue to come back here almost every day. : )

Also on the D300 Minisite. For the AF system and module, Expeed image processor and Scene recognition system they say it's a feature shared with the D3

To be precise they say "common feature with the D3". But that's not saying it is identical to D3.
 
I'm just imagining the Nikon engineers back in Japan reading these threads and having a hardy laugh as to all the guesses vs. what the actual AF systems consists of.

If you go http://www.youtube.com/watch?v=9DKi4FAl2Ds here you can
hear it from the mouth of Lindsay Silverman, Nikon's Senior Technical
Manager, is that good enough for you? He describes it as identical.

At ca. 8:20 min into the interview he says about the D300 "... it's got an identical ahm... 51-area autofocus ..." - yes, I hear it, but still I don't believe it. Yes, nasty me, but as he says "... an identical ... 51-area autofocus ..." and not "... the ... identical 51-area autofocus ..." I'm still not convinced, more so as he's not able to pronounce the name of his employer correctly.

Yes, I give it a rest in this thread, you have your interpretation, but I have mine...
 
Guess I took your statement, "That you could have the camera for more than 3 whole hours with 9
different lenses and come to such a conclusion? Next thing is you
will tell me that no, the Sky ISN'T Falling :-) :-). Yes, that is
sarcasm, pure and simple.
Thanks for chiming in Philip. For some strange reason it is the
experience of folks like yourself, who have actually had the
opportunity for real world use, that I put more stock in."

A bit insulting but it's ok, sometimes things come out different when you read type and cant really understand someones intentions.....Like I said, I hope more than anyone Im dead wrong about the issue and have asked Phill to please include the AF testing in his review. Otherwise young man, we have a fort to build and some drinks to tip back! : )))))))))))))

You have your opinion, I don't know you from Adam, but I do know,
personally as well as via the Net, at least 4 people who have had
experiences different than yours.

So, I guess that, by your logic, if Phil (Askey this time) not
Philipp has the D300/D3 for more than 3 hours and comes to a
differenct conclusion than you do, you will reject that as well? I
guess we all have our "heroes" don't we? :-) :-) :-) :) Yes, that is
a JOKE son, just a silly joike.

I also don't know the other people who saw the same thing you did.
Can you please post there Bona-Fides for us all, so we can compare to
those of others who have had different experiences?

I'll ignore the rest of the "personal" comments, such as my being
dense, just in case your comment later in the thread is directed to
me. And should we meet in Fort BillDave (just being Alphabetical
about the naming), I'll buy the first round ...

What is very encouraging to me as well, but not surprising after the
D200 situation, is that Nikon kept things correct for the Sigma
lenses.

While the couple of days I had both cameras I couldn't see any
difference in focus speed with AFS/AFI/HSM lenses the HSM lens was
particularly important for me as I use the sigma f5.6 800 prime a lot
the d300 seemed both faster and more accurate than my d2x d200 D1x
and a few other Nikon digital bodies I have.

Phillip.

Ps from what I was told both be focusing modules are exactly the same
the only difference is the housing that they are fitted into one
housing for the 35mm sensor one housing for the cropped sensor.

The only reason I am so confident is that I was at the NPS Roadshow At Nikon UK in Kingston Wednesday and I did ask the question and they said it's the same system. But maybe it's a big conspiracy. I handled both (not for anywhere near 3 hours) and couldn't see any difference in AF performance but didn't have any really challenging subjects to try them on so only time will tell.
 
another useless comment...

WHY CAN'T PEOPLE LIKE GO AWAY?

We are discussing it for fun and speculation. Especially since many of us are deciding between the two bodies, and want to get a preorder as soon as possible to avoid delays. Since many have shot with both cameras, it may help us decide.

No go find some other people to be a prick to.

Every day I look at ads for tech products and see so much missing. Why run a 2 page color ad about a printer and have no descriptive info - like what is the maximum width paper?

Marketing people don't seem to be good at figuring out who their customer base is and presenting them with the best info they can. There would still be ad room for the color pizazze.

I guess we would all faint to see Nikon have a complete comparison chart on new camera releases with lots of detailed specs. Maybe like Dpreview runs or better since Nikon does know the numbers.
