the Eric Palmer 3.0? haha don't have a main body, just have 2 that I use. 1 is better for natural & lower light (D200 want to upgrade when the D800 comes out) & the other better for flash in bright light (D70). Like having a DH rig & a BMX, neither is main, one is just for street & the other for downhill.
nah man, it's a great lens. I use mine loads. Just watch out for getting your own feet in the shots & you've gotta get really close with it coz it's so wide, so learn to shoot without looking through the viewfinder & you're good
