6. Tamron 15-30mm f/2.8. One of my favorite wide angle lenses I’ve used is the Tamron 15-30mm f/2.8. It’s a heavy lens, but it matches or even exceeds the Nikon 14-24mm f/2.8 in image quality overall – plus adds some modern features like vibration reduction and a water-repellant front element.
However, Tamron’s 16-300mm has a slightly wider angle of view, is smaller and lighter in weight, and better value for money. Tamron 18-400mm: Specifications.
