I have a brand new Nikkor AF-S 24mm F1.4 lens for sale. It is unopened and was purchased a few months ago, literally just sitting there collecting dust. I've made the controversial switch over to Canon, so all the Nikon gear had to go, this is the last piece left (I originally had two).

I see it listed on fleabay for over 2k.

I am offering mine for:

$1,900 + shipping

It's an awesome lens, great bokeh, unparalleled performance in poor lighting, lightweight (relative to other zoom lenses like 24-70, 12-24). Warranty is still valid, and I will include the original sales receipt.
