New mounts may have new licensing restrictions. So far, just to ragtag outfits like Viltrox are making a few.

I don't believe that has stopped 3rd party manufacturers before. Maybe they just haven't figured out the reverse engineering yet. Tamron making lenses for there Sony E Mount is a definite plus as Sony lenses are pretty pricy.

That's my understanding as well, that Canon and Nikon mounts are reverse engineered. I wouldn't have that RF and Z mount protocols would be all that different, but maybe they are?

I believe Sony actually provides 3rd party manufacturers with protocol information for E-mount.

I am not sure about Sony’s arrangement. If true, Sony is betting that 3rd party lenses can increase their platform popularity. Canon and Nikon are trying to protect their lens sales. I predict Sony will increase their MILC popularity at the expense of their competition.

The Tamron EF mount lenses of late have been getting very good optical reviews. This includes the 17-28, 28-75, 28-200 and 70-300. The first 2 are f/2.8 lenses.

I believe you're thinking of the RXD line, which are mirrorless lenses (for Sony E-Mount)?

There are Tamron EF-mount (Canon) versions of 28-75/2.8, 28-200, 70-300 but they are all really old. There is a more recent EF-Mount 17-35/2.8-4.
Yes, the full frame Sony E mount lenses. They aren't quite as good as some of the more expensive Sony G or GM lenses but are very good for the money and in most cases the better choice based upon cost.

They are also smaller and lighter! I really like the 28-200mm as a versatile lens, even on the 61MP A7R IV, it does a good job, and it is smaller and significantly lighter than Sony's 24-240mm.
