Our value packed optional lens upgrade will allow you to use one of our fast, wide angle prime lenses by Nikon and other manufactures. Our lens upgrades provide you with a lens that is one full stop faster than our standard option which allows you to use faster shutter speeds and create slightly sharper images of the auroras. While we are 100 % confident that you will be satisfied with our standard lens option, this upgrade will surely be a good choice for all of our clients that are advanced photographers or for anyone who prefers a slightly better optical resolution.
