Hey guys, After being on here a couple of months and doing research, I decided on a D40x (and ended up getting surprised with it as my engagement present from my fiancee!) I ended up going kitlensless since I knew I was going to upgrade to a fancy AF-S lens of some sort, but am sort of kicking myself in the ass now (well she actually decided to go without the kit lens since the body was only $580 shipped, woah prices have dropped!) I got a Nikon 55-200mm AF-S VR lens which has treated me well so far, but after a recent trip to upper Mass for a retreat with LOTS of landscape photos, I'm feeling the itch for a wide angle. And this is where, as a newbie, I feel restricted by budget since I can "only" get an AF-S lens compatible with the D40x I own - and don't even suggest manual, I'm having a difficult enough time getting my AF-S images focused right now! The options I seems to have are drop $900 for a Nikkor 12-24mm with AF-S OR try the Sigma 10-20mm lens with HSM. They say the sigma has "color fall off", what in god's name is that? I recognize that if I don't know what it is, I probably shouldn't worry since I"m a noob, BUT my learning curve was drastic this weekend and I figure in a couple's year time, I'll get peeved about draw backs since I'm already annoyed with some of the choices I have made. . .
