So am I. Its size is somewhat of a damper for my excitement, but I can always use it with F100 and leave 24/2 for F3HP. That is, if I manage to convince myself that I need another fast 24, which won't be a simple task.
By the way, how do you know it will start selling in February? I haven't heard anything which, to be honest with myself, doesn't mean much.
My favorite wide (that I own) is my 18mm f/4 AI. It's not exactly rare, but it is hard to find. Even so, it's extremely affordable and optically sufficient. Barrel distortion can be noticable (depending on subject matter and focus distance), and it takes giant series IX or 86mm filters. Also, the screw-in front cap and the screw-in hood can't both be attached at the same time! I don't mind the slow aperture; I can usually get acceptably sharp images hand-held at 1/8 at this focal length. I have to admit I like using it because it's a beautiful lens that you don't see very often, but I really do like the pictures I take with it.
My first wide was the 24mm f/2.8 AI, and it is optically superior in every way compared to the 18, but it mostly served to help me realize I wanted something even wider.
My absolute non-favorite wide, which I use too often is the Rokinon 14/2.8. Every time I mount it on F100 and look through VF I go whaaaaa?! and then run to my mommy crying (well, sorta).
I haven't made a single good picture with it, I just don't know how. I'll keep trying though, freak accidents happen every day.
My 35/2.8 'K' and 35/2 O are both very sharp. The 35/2.8 PC doesn't get used as much but is also very sharp. I find the 28/3.5 AI very sharp and have two of them. The non-Nikkor wide angles I like include a 24/2.5 Soligor, 28/2.5 Vivitar Fixed Mount, 35/1.9 Vivitar Fixed Mount and if I need something wider I can use a 21/3.8 Vivitar T4, which is surprisingly sharp.
