Hello, I'm new to the forum and am researching lenses for my D70. There is a huge price difference between the Nikkor 85mm F/1.4D and the 85mm F/1.8D. I'm just a weekend amateur, looking for nice shots, but not expecting to compete with the pros. Does anyone have an explanation on why the price difference is so high between the two? 1.4 vs 1.8 doesn't seem to warrant this, but admittedly I am a newbie. Thanks for any input.
