Funny you mentioned this lens. I just sold my nikon 1.8D, and i was about to place the order for the new nikon 1.8G. But i started running across many reviews about the Rokinon. Many say that it is VERY DIFICULT to use, so i was very very scared about getting it, but because i have been wanting a 1.4 for a long time, for i could never afford the nikon 1.4D or the CHEAPER BUILT Sigma 1.4 even USED!! That is why i decided to give Rokinon a try. I have the D7000 and this lens has BLOWN ME AWAY!! The lens construction is just as good as the Nikon, better than the Sigma. The BOKEH is INCREDIBLE!! and already SARP at 1.4. The lens works PERFECTLY on my D7000 because the lens FOCUS RING does not rotate TOO FAST, the camera catches the FOCUS POINT RIGHT ON. To me this lens is very easy to use, with some practice. I hear that Nikons comparable MANUAL FOCUS lenses cost about 1k??
Personally i think this lens OVER ALL, blows away the new 1.8G, It just does not have Auto Focus, to me this does not really matter because 85mm lenses are PORTRAIT lenses anyway. The new G lens is very very good, the GLASS has been updated from the older 1.8D, but people have to understand that Nikon made this NEW G lens a CONSUMMER GRADE CONSTRUCTION QUALITY, while the older 1.8D IS A PROFESSIONAL GRADE QUALITY lens. With this tough economical times Nikon decided to put better glass in it, surrounded by cheaper and LIGHTER material. Personally, i dont like light weight lenses on my D7000, I do not like the cheap feel and GRIP. For the ones that will be getting the G lens make sure you PROTECT IT at all times, if you bang it against something, GOOD LUCK! I want to thank all the forums and people that have recomended the Samyang/Rokinon, if it wasn't for them i would not have this JEWEL on my hands right now. The Nikon is an awesome lens, but to me the Rokinon is BETTER.
