Recently though, they have been putting a ton of work into it, especially the FF. They released 9 lenses this year alone. And some of them are absolutely extraordinary. The SEL70200GM is an absolute monster. There were even more third party lenses released.
Still, there is a lack of budget options, especially for crop e-mount. There isn't very much good long lenses either. There is only one G lens(Canon L equivalent) that goes up to 300mm. Nothing longer.
The main advantage for Sony is that they release their autofocus specs to pretty much everyone. Autofocus adapters exist for pretty much every major mount, and they actually work. Full native autofocus speeds(on modern bodies that is), not reverse engineered janky messes. And the techart pro adapter will adapt anything else, even stuff that doesn't natively autofocus.
