I use a fuji Film S5. Original lens would probably be considered to be Nikon lol. But i only have 3rd party lenses. Sold off all my nikon lenses. Have a tokina, tamron, voigtlander. Now left to get a sigma
I only have one Nikon len which is the 50mm f1.8 cos it is cheap and is one of the good ones in Nikon range. The rest of my collection are Tamrons & Tokina which are those that have received good reviews and worth getting.
Main reason: Go for good lens with reasonable pricing.
14-24mm f/2.8 AF-S would be a better comparison for different grade of lens. This nikon lens is way better than the tokina. But yeah i can't spend the high $$$ for this lens, so i'd spend less for a tokina instead of 12-24mm f/4 DX. It's about 300ish more expensive, but apparently doesn't perform as well as the tokina.
This is just my noobish opinion. Do share if you feel anything wrong with it.!~
