Samyang has released a 24-70mm f/2.8 lens for Sony E-Mount that not only features autofocus but is also parfocal. This means that as you zoom the lens from one extreme to the other, the focus distance does not change. This is typically more in line with lenses geared towards video rather than photography and is normally quite pricey.
The lens appeared for sale in Thailand — and only Thailand at the time of publication. It is likely the lens will eventually become available in other countries and given it promises autofocus, is parfocal, and is listed for an equivalent of about $900, it is likely to be quite popular if the image quality is even close to what is expected out of third party optics.
The Samyang AF 24-70mm f/2.8 FE features 17 elements in 14 groups and includes two aspherical elements and three extra-low dispersion elements along with one HB and three HR elements. The front element has a special UMC coating as well. It has a close focusing distance of 35 centimeters and promises round bokeh thanks to a nine-bladed aperture. The autofocus is powered by what is described as a linear STM focusing system.
The lens also features a built-in custom switch that switches the ring between focus and aperture control.
The lens description says that not only should it perform well with regards to its autofocus capabilities for stills shooters, but the parfocal nature also makes it ideal for video work, therefore making the lens an excellent hybrid shooter workhorse optic.

The Samyang AF 24-70mm f/2.8 FE also features some measure of weather resistance and is protected against dust and rain. The lens is compatible with all Sony E-Mount full-frame cameras and can resolve high-resolution images as well as 4K and beyond. The lens is also covered under a two-year warranty. There’s no word at the moment on if or when this lens might be coming to the rest of the world, or whether it’ll keep the same sort of pricing.
