I suppose that all your test have been done with the same kind of lights. Try to Fine Tune your lens on a sunny day. It might make a difference.Using all those methods is very dangerous. As they...

You might see that because:- AF Fine Tune depends upon color temperature- Your method for fine tuning is not precise enoughI use a slanted ruler tool with controlled light conditions. It is very...

What happened to your camera ? I have no idea.But if you shoot 260 pictures in a row without a single focus issue, I suggest you should try to walk on water. If your shots are wide open with fast...

I have a tool such as LensAlign. It is extremely accurate to measure the optimal AF Fine Tune for the different AF sensors and the different lights. The results are posted just above. The optimal...

You guys should stop smoking. I think I have one of the best database for AF Fine Tune for my lenses and my D800. I have measured the optimal fine tune back and forth for different kind of lights...

Hi Gethin,It is always difficult to assess the quality of a lens like that. From what I see, it is true that it is sharper on the right side than on the left side. My experience with lens testing...

Don't think so.Buy a LensAlign and fine tune your lens for center, left and right AF sensors. Then pick a number in between and go out and shoot real subjects wide open.If you still have problem,...

Very interesting. I had exactly the same problem: my D800 has been sent for a fix for the left AF issue and came back with a good front focus that is even more important in incandescent light....

For the same reason Canon can't make an imaging sensor that has the dynamics of the ones used by Sony. They just don't know how to do it yet.I think Marianne Oelund has a lot of experience and she...

You seem to have everything to work that out easily.Could you please let us know which lens you are using and which amount of Fine Tune you need to get the left, center and right focus points to...

My experience with that is that the amount of shift depends on how the body is calibrated. I had a D800 which gad a slight left AF problem and send it to nikon for adjustment. It came back with an...

I have tested a lot of D800, and my experience is that:- If you want it to be fine with fast primes wihout fine tuning, you are going to go through a lot of them. I have tested 5 so far, and my...

That's up to you.I do have a license of Focal, but I've almost never used it. One of the reason it that as every new software, it comes with bugs. It might be better now. Moreover, people are...

Also, set the sharpness to the maximum in your D800 and use ViewNX to convert your files. It will be easier to check the depth of field.

Hi TOF,Here is a curve like the one given by focal. It is an AFS 24-70mm at 24mm and f2.8. The blue and the red dots are shots done at a given AF Fine Tune value.First thing you will notice is that...

Thanks for the pictures. It seems that you have a little bit of back focusing with the left AF sensor.Could you please set your AF Fine Tune to -5 and then, try again? It would be nice if your...

Look at those pictures. This is my D800 with an AFS 85mm f/1.8. I have focused on the black and white stripes for every single picture.First, without AF Fine Tune. Look at the stripes. They are all...

Would you mind sending crops of your pictures with the slanted ruler for the left, center and right AF points ? It would be nice to see the target in the crops too.It would help us to know if it is...

My advice would be to Fine Tune your lens. The only thing we know from these pictures is that the left and right sensors are off without AF Fine Tune. What about the central AF sensor ?My only...

My claim is a little bit different. A difference of 3 AF Fine tune units is the lowest difference one could measure. Such a body would be perfect. I would require also a perfect lens. I've never...
