I very much doubt you would find a fake lens, even in HK, its just too complex a device to be able to fake. I Dont have anything for sale, but can offer a little advice. I have the 50mm f1.4D lens and this is a rather good lens for low light shooting, a little soft at f1.4, but above f2.0 its very good. but i realise this is out of your budget, but may be more in budget if you buy once in HK. if you are buying an older lens from a film nikon, it will still fit but the crop factor fo a digital nikon will make a 50mm lens about 80mm, so go for a 28- 35mm manual focus lens to bring the crop factor to around 50mm on digital. use the 'green dot' inside the view finder to help make sure the lens is focused properly as such high F stops like f1.4, theres very little movement of the ring needed to take a shot out of focus.
