D300 AF Fine Tune Feature examples

Simply stated, it works wonders, :biggrin:

Some of my lenses worked better or worse on some cameras for slight front or backfocus at wide open apertures, I tended to shoot some lenses on certain bodies because at 1.4 or wide open, the camera was spot on with this lens but on the other D200 or D2Xs it might have back focused or front focused a bit. Every camera is just a smidge different, and coupled with the lenses, I actually had a card set up for which lens with what camera for those 1.4 or critical focus situations.

Well those days are over. I just took all my Prime lenses and set up a focus test and I was able to dial in all of my prime lenses with the AF fine Tune. They are in the memory and the camera automatically remembers the lens etc. etc. so Cool!:biggrin:

I left the camera overall setting set to default, and I found my 105Vr was spot on, the 50 1.4 was spot on, my 85 1.4 needed an adjustment of +10, which means it was front focusing a tiny amount at super close range, and my 35 f2 needed +5.

At ranges of 2' feet or so I was able to adjust the AF fine focus to move the focus point nearly an inch forward and or backward with a setting of +20 or -20. Very very nice. This of course means that at long ranges the front/back focus range is even greater. With my 180 Prime I was able to move the focus area at least a foot front to back at 40 yds.

Thought I would let you all know the good news. Very easy to use and very very nice. for those of us who shoot indoors wide open this is great news!

Great post,

This is very useful, and the more control you can have over the performance of your lenses the better.

Thanks a lot.

Re: D300 AF Fine Tune Feature examples

Thanks for the info! Is the adjustment done by the camera or the user?

3rd party lenses?

Hi and thanks for the test. This is helpful info.

Do you have any 3rd party lenses that you can try. I am still unsure if this only works with Nikon branded lenses.

Cheers

Allan

Re: D300 AF Fine Tune Feature examples

user set and adjusted and once adjusted the camera will remember the settings with each lens.

Wow that is a killer feature

So simple...I bet it will be copied by other companies. I am a big nut on focus, i want good focussing.

Re: Wow that is a killer feature

I vaguely remember reading something about this in-body AF tuning, I believe this has been in the Canon 1D series bodies.

If that was the case, get your flame suit on!

A nice little perk. Thanks Nikon & Wade!

Patented?

Not if Nikon was smart and patented feature. For example, the reason that you have to press the pop-up button on the built-in flash on your Nikon is because another maker patented the feature of an auto-pop-up flash when the light is too low.

It it worked in auto based on the light level, I would have to patent a tape over the built in flash to keep it in place

I would really hate to have the flash working without my consent.

And it was Canon with the 1D III which get to the market with AF fine tuning for different lenses.

Canon had it first in the troubled 1D III

(the one with the focus issues or recall) However Nikon brought it into the mainstream with the D300. For those that are picky about focus...it's a great feature, it would appear.

I was impressed when I read that spec when that body came out. I'm even more impressed we can have it in our D300 without having to spend $4000+USD to get a body that has such a useful feature.

Re: Actually it is much better this way :-)

THANKS so much! That's fantastic to be able to fine tune lenses. As most of us know variations are subtle, but pretty common. I had a sample variations on Canon and Nikon glass, so this is great news!

Two more days!
