I would add that the +10 setting does not make either the lens or the camera bad. Every part has tolerances. Without going into this in depth suffice it to say that sometimes tolerances stack up in a bad way. In this case AF Fine Tune helps. Before when this happened either the lens (or camera) got returned as a "bad sample" or the combination was shipped to Nikon where they did the Fine Tune adjustment (they could do this long before we got a menu item so we can do it ourselves - and they didn't add it to the menu so we could use it to create OOF shots - they added it because sometimes it's needed, and it works when properly set).With respect guys(Colin and Randy) it is a fact that some lens body combinations do absolutely need af fine tune adjustment depending on the actual examples owned,
they all vary to a lesser or greater degree.
Also some of us are suitably experienced to know when it is needed, your general
suggestion that it is not needed can be misleading.
Absolutely agree that anyone with a new camera lens should try it at factory default
settings extensively if necessary before attempting calibration.
For example my 300 afs 2.8vrII &D7100 requires a +10 adjustment, fact.
Surely April FoolsFor what it's worth, after a week of using the D7100 here are my casual impressions.
General handling, ease of use. I much prefer the D7100, shutter seems quieter, viewfinder brighter and the information display easier to see. Controls are pretty much the same, although I really don't like were they assigned the AF/A-S-C, but this is something easily overcome by use. The camera "feels" boxier and small in my hands, with the D90 I never felt I needed the battery grip I will definitely by adding one to the D7100. Using the AE-L lock button for AF is comfortable, no issues with other controls for me. Lens focusing is fast with less hunting using a long telephoto then with the D90 - a big plus.
Image Quality. Once AF fine tune is locked in, nice clear and sharp resolution. Colors seem well controlled , image almost has a "film like" quality (I don't mean grainy!) but all my testing so far has been with a 300mm f4 AFS, so a lot of this also is a quality if the lens. The biggest issue I have so far is there is more then expected color noise in shadow areas, compared to the D90, however this was easily and well controlled by turning off noise reduction in Capture NX2 and using Noise ninja (only a touch needed - dialing back from the profile value of 10 to 7) and judicious careful sharpening. Combating noise from this sensor somewhat negates the extra sharpness gained, but not enough to be a deal breaker, just be aware that you will be doing more file processing to achieve excellent results. Noise in shadows was evident in ISO settings greater then 800, thus I am dialing back auto ISO settings from 1200 to 800 on this camera, which is where I was at with the D90.
Below is an image taken with a 300mm +TC 1.4 shot in the 1.3 crop mode and then further cropped by appx. 40% still yielding an image of around 26 Mpx at 300 dpi. ISO 1100 F6.3 1/800s. For my needs the D90 could have come close to this image quality but the resulting file size would have been around 8-10 mgpx, much too small to up-size to use for stock photography, so the D7100 is a big help in creating more keepers because of resulting image size, not necessarily image quality.
I don't get it. I have had very few fast lenses(1.4 and 1.8) that have not benefited from at least a little lens fine tuning, not as much from the f/2.8 and smaller apertures. Maybe it's just those 1.4 lenses that are making us all nutty. Come to think of it I don't think I have seen you post a lot of stuff at 1.4. I think that may be the secret to enjoying photography, staying away from those lenses...
Well I too am in the never had to once do a fine tune. I did try it though once and found it to actually screw things up focus wise. I find that using the sharpening in camera works well for my jpegs.:smile::smile::smile::smile: bout time someone feels the same as me.
My latest camera is the D7000 and my previous "new" camera was the D300.
+1That completely baffles me that you have never had to do that ever? Either you are the luckiest son of a gun or you are a post processing wizard... Or all of us fine tuners could be crazy. :biggrin: I need to get a hold of some of your nefs to see if they are really in focus... LOL
i do as well (find the af adjustment business curious), why some need it and some don't, not sure we will ever really know why...I find these fine-tune comments curious! But no time to think about it, I'm off to the race track to meet my mechanic where we will be trying out a different set of tires and and readjusting the timing belt. I know all this tinkering will only get me a few more horse power and a bit more speed, but given it's a Porsche and the money I spent on it, it's certainly worth the effort to make the most of the engineering and it's capabilities. My wife thinks I'm crazy and drives it at no more then 60MPH and she says "what's the problem - it get's me to the supermarket!"
ok - I'm kidding, I'm not married.
Brand new camera out of the box shouldn't need any AF fine tuning.The AF fine tune is a disaster waiting to happen. Brand new camera out of the box shouldn't need any AF fine tuning.
I've used plenty of non Nikon bodies to know how good other makers can be for AF accuracy. Nikon's not one of them..not even close
I think most people just stop down a bit to get into their lens' sweetspot when they discover softness in images. The added DoF fixes any autofocus finetuning that may have been needed. Wide open apertures would be a different story naturally.
I've always started at f/8 with my 70-300 since it offered the best IQ and worked from there. Perhaps it was a DoF issue with incorrect focusing in the first place and not so as much a flaw of the optics of the lens as I thought...
Doubt it. That lens is known to be best at f/8... why is another matter... but I know I was never truly happy with it until I used started using it at f8 exclusively. :smile:I've always started at f/8 with my 70-300 since it offered the best IQ and worked from there.

Im with you Randy. Never had to adjust AF and I would probably return the camera if I thought it needed it.
