I think you misread.


also, it does NOT affect only Sun shots, it also affects any strong light in a tight angle, while outside the frame.

Adding to your "tight angle"; The light source seems to need to be a point source like the sun and it has to be real close to the edge of the lens without being in the frame. In other words, almost a very precise set of circumstances.
Since most users will not be shooting under those conditions and the ones that do will make it a rare occurrence, the "problem" is not of major proportions. Kudos to Nikon for taking steps to correct it though. And before someone else brings it up, it appears that they learned from their past mistake (D600)

As you may or may not be aware, we all come equipped with our own 18% "grey card". the palm of your hand is pretty much neutral grey.


and it's much easier to carry along with you than a "gray" card which gets weird if it gets rained on. I have thought for a long time that the card should have been named an "18% reflectance" card. Its intended purpose was all about the quantity of light not the color.

Design tolerances can vary between lenses, even of the exact same model. While these variances are minimal, the lens to sensor distance is so critical that if a lens is at one end or the other or the acceptable tolerance window, you may not be totally happy with the sharpness of the resulting image. Better quality camera bodies all allow for the end user to "Tune" the AF point of that camera to the particular lens in use.
Its actually a very simple operation once you learn how to do it, and each photographer whose camera has that capability definitely should take the time to at least TEST each lenses AF accuracy so he or she KNOWS what that lens is focusing on. Adjustments can be, and usually are, quite minimal, but can make a very noticeable difference in image sharpness and overall quality.

In addition as you use your camera and swap lenses sooner or later the wear on the mount can affect focus settings, as can silly things like temperature changes. Not to any great magnitude but over time the various things that can alter the original setting can add up and may require you to re-tune your focus settings.

There was a minor problem that might have shown up in unique situations. Yes I'm having a bit of fun there. The 750 if used in a situation where you were attempting to introduce flare into a photograph by shooting towards the sun, or other point source of light, at a particular combination of angle, light source and luck, a narrow band caused by an internal reflection would show up in the 'flare'. I'm guessing that Nikon rather than face a PR nightmare like the D600 problem decided to recall the camera and address the issue. (that 99% of users would never encounter.)

When I fine tuned my lenses I checked the zooms to see what adjustments would be needed for both ends of their lengths. Fortunately in my cases the adjustments were not extreme. I opted then to make the adjustments on the long or max end of the zoom reasoning that at the short end (in your case, 24) the increased depth of field would help to compensate.

IF; If there has been a damp winter and spring there can be an incredible poppy explosion at the higher elevations east of Tucson. From say the Cochise county line all the way to Wilcox, Safford and Morenci. The usually fallow fields and hills will literally be covered with orange/yellow flowers. I hope you are fortunate enough to witness this.

I've been lurking here at UHH for a while but this subject spurred me to respond. I think I understand what you are looking for and did a quick "creation" to try and illustrate what I think meets the criteria.
