Been looking at the above three lenses and am wondering if it is worth getting the 20-35mm f2.8 over the 35mm f2 and 24mm f2.8; the price difference is $100+. I have been quite keen in the three lenses as I like to shoot rather wide and would prefer to move closer to my subject (where possible) than to zoom in. What I understand is that the 20-35mm f2.8 is a brilliant lens but is rather heavy. The 35mm f2 is a pretty good lens too but if buying a used copy, will have to avoid the older copies due to the oil issue. The 24mm f2.8 seems to have people rather divided as some swear by it while others hate it. I would love to get the 17-35mm f2.8, but that is out of my budget. I am not really considering DX lenses too because I would prefer to buy a lens that I can use on my D70s and F3HP. Would really appreciate if anyone can give me some advice on the above lenses; especially those who had used them before. Thanks!
