This adapter creates the bridge between the old Sony / Minolta world and eMount world. All A-mount lenses with autofocus can be adapted without any restrictions and the AF is also very fast. The first objective was the Minolta AF 50mm 1.4 - very fast and the AF sits at 100%. Meanwhile, I can also try a Sigma 28-300 and 70-300, both also very satisfactory. If it takes any longer, until more full-frame lenses come eMount, I will certainly buy me another A-mount lenses. The only limitation is due to the basic principle of Alpha cameras where the image stabilization in the camera, just a few Sigma lenses have an image stabilizer (for example: the tested Sigma 70-300mm OS lens F4,0-5,6 DG) The also available Canon adapter is in contrast AF very slowly, because he goes once through the entire focal range, before it achieves focus. Rein of the optics, the adapter disfigured by the square box to the elegant look of the A7 unfortunately very. That alone is a reason to buy the sauteuren Zeiss lenses, but that's the only downside.
