We will just have to agree to disagree then, none of your arguments make any sense to me. Nikon has famously long-lived compatibility, and they have always tried to maintain it, right up until it was hurting their business and they had to make a new mount. Even then they produce real adapters to make older lenses work on the new camera line, as much as possible. You have an incredibly jaded outlook, for no apparent reason. AF-D is a notoriously quirky specification, with a screw-mount for focusing, which would have been expensive and complicated to support, and possibly forced the new cameras to be larger. The "current" mount, a-la EF if you want to compare to Canon, is the AF-S line, which has since the 90s.
If you really want to point fingers, Canon is the company to look at. They have broken compatibility deliberately. The fact that you have chosen to buy ancient auto-focus lenses, which were then not supported in autofocus mode when the new bodies came out, is unfortunate, but you can still use them in manual mode, which is far better than what Canon did. You could have bought an entire FD Canon system, and the following day they were unsupported on new bodies. With Nikon you had to wait almost three decades to have a similar effect. There were a couple of lenses, like the defocus lenses, which were still AF-D until recently, but the vast majority of Nikon's huge catalogue has been AF-S for over twenty years, and they are all still supported.
Btw, Sony bought Minolta when they started with DSLRs. I think they kept that mount initially, but I have no idea what support they give to older Sony and Minolta lenses with their E-Mount....Show more →
Here's a chart from Sony, if you're interested, but, basically LAEA1 and 2 are APSC versions of 3 and 4 respectively, which are for FF. 1 and 3 use the camera's AF system and work with SSM/SAM for single and continuous modes and eye AF is available, aperture control, and EXIF. The 2 and 4 use an AF system built into the adapter that was borrowed from the a99 (SLT included) and will AF all SSM/SAM/screw-driven lenses, but only as well as the a99 did and eye AF is not available. Aperture control and EXIF are available. The 5 is the 3 with a built-in AF motor to drive the screw lenses with some cameras. With the A1, a9III, a7rIV, a7IV, a6600, and FX3 or later, it will use the camera's AF system to drive SSM/SAM/screw-driven lenses in all AF modes and can utilize eye-AF. If I remember correctly, older cameras lose AF on the screw-driven lenses and SAM lenses are limited to single-shot, contrast detect only.
