Samyang 75mm f/1.8 FE lens is in Stock at Amazon, BHphoto and Adorama.
Marc Alhadeff from SonyAlphaBlog concluded:
The Samyang 75mm F1.8 AF (440 euros) is an excellent lens for Sony A7 system. It is an unusual focal length but very practical on day to day. The lens is designed to get a maximum of performances in the smallest form factor possible
Everything is not perfect but the lens scores very well on all the main points : very good to excellent sharpness, very good color rendition, beautiful blurry background , good bokeh balls wide open & at F2.8 , efficient AF, small/light/cheap on a full frame mirrorless
It is also a very innovative lens for Sony E mout with a button that allow to either use the focusing ring to focs or as an Aperture ring without going to crazy price. An excellent idea and almost a reason for me to buy this lens
The lens will be perfect up to 42 Mpix , on the 61 Mpix although results are not top notch wide open (only very good) you need to close down to F2.5 to get excellent results. But this is similar to the Sony FE85mm F1.4 GM that cost 4 times more !
Shooting with this lens is a pleasure and overall it is an excellent value for moneyPros
