SAAB wait until you get enough lenses that are whatever Nikon's pro level is, then you can remove half of those other plasticy toy lenses. In all seriousness, you have a good little starter collection for a pilot. Have you started a little side business yet to your flying (portraits, weddings, stock, commercial etc?)
I seriously almost posted a pic with stacks of all my lenses... but then I felt a little silly considering it, and then I found this pic which I thought would be much funnier.
My weapon of choice!!
