I am trying to decide between these two lenses for my D7000. The 1.8 is lighter (by 100g), cheaper (by 120GBP) and, according to MTF and initial tests, sharper. I also hear that, due to the manual focus ring being less sensitive/precise than the 1.4, the focus is a bit faster? Anyway, I may be splitting hairs with the last one but, all in all, the 1.8 seems more appealing on many fronts. However, the 1.4 has 9 aperture blades. Does this have a significant advantage over the 1.8 or are they pretty much indistinguishable? Has anyone purchased the 1.4 just for this reason? I have seen images from the two taken wide open of lights against a dark background to record the exact shapes of the aperture opening but is it an issue? If the two lenses both shot a portrait against neutral tones of foilage without any highlights would the bokeh tell one from the other? I also heard somewhere that, stopped down to the same aperture, the 1.4 bokeh would be more detailed. Can any one explain why? Many thanks for your time. Oh... come on Nikon, release a new AF-S 85mm 1.8G (or even better, an AF-S 100mm f2G) this August pleeeeeeease!!!
