d, i was thinking the same thing.i only have a crop sensor(d7000)LOL. my plan actually is to get an 18-200(as a walkaround),and get an 85mm(0r 105mm macro), f1.8 for portraits. that is all will just be in my bag.am having a hard time switching lenses most of the time, and usually i'm using the 70-200 as my walkaround(so big and heavy to carry)

we'll see,i'm still weighing things.too hard for me to let go of the f2.8 sigma70-200, i've got a good copy, it's sharp.
thanks for the input d. : )
