SonyAlphaBlog tested the new Samyang/Rokinon zoom lens and concluded:

The Samyang 24-70mm F2.8 (900 euros) is globally a very good lens at a reasonable price but the competition is very tough and offer excellent options that are all better in one or several areas compared to the Samyang 24-70 F2.8

Area where the Samyang is below its peer are sharpness , build quality/ergonomics , size and weight, AF , bokeh balls shapes,
Areas where it is similar or among the best are : color rendition , background blur
Area where it is above the others : Distortion , Vignetting , ergonomics for video, focus breathing , par focal (when starting at 70mm)

If you need a 24-70 my recommendation stay the Sigma 24-70mm F2.8 DG DN Art (1200 euros) better in all areas (except video) for a price tag +33%
if you want the best option at similar price and are ready to sacrifice the 24mm , then the Sigma 28-70 F2.8 DG DN Contemporary is the best option at 50% of the weight
For pure video work and for 24/33Mpix where you really need the 24mm, the Samyang is a recommended choice

Recommended for video work
