The 10 Best Nikon Lenses

When digital cameras first made contact with consumers, the best among them boasted APS-C sized sensors, which are smaller than a traditional piece of 35mm film. Camera manufacturers were smart enough to keep the design of the lens mounts the same, so that shooters could jump to digital without having to buy new lenses, but the difference between an APS-C sized sensor and what we now call a full frame sensor caused a change in the lens' focal lengths.

On an APS-C sized sensor, a 50mm lens shoots roughly 75mm. A 20mm lens shoots roughly 30mm. That's because the crop factor between the two formats is about 1.5x. You can divide the focal length of any FX lens (FX is Nikon's full frame lens shorthand specification) and add that to the original focal length to get the crop factor figured out.

Over time, Nikon produced better and better lenses designed specifically for their APS-C sensors with DX as the specification, so that new photographers or shooters jumping to Nikon from other brands wouldn't have to do that extra little bit of math.

If you already own a Nikon body, or if you're shopping for Nikon glass to use with an adapter on another body, it's best for you to double-check that sensor size. There are simple charts across the internet that break down each sensor size and its corresponding crop factor for you to investigate. After that, the big question becomes whether you're a zoom person or a prime person.

Zoom lenses allow you to achieve different focal lengths with a single lens, so you can do more diverse shooting without running all around a space or changing lenses over and over again. They're great for sports and event photography, or anything that requires lightning-like reflexes from a photographer.

Primes are a little better suited for art photography, fashion photography, portraiture, and videography. They tend to be a little sharper because they require fewer elements and they don't need to balance sharpness across any more than their single focal length the way that zooms do.

Figure out what sensor size you're working with, and what kind of shooting you want to do, and you'll be well on your way to finding the perfect lens.

Early camera lenses–the ones that accompanied the earliest cameras in the early years of the 19th century–were a single piece of glass, coarsely ground and wildly inconsistent by today's standards. Photographers in those days had little control over focus, and their only options for focal length depended on the placement of camera and subject.

In 1839, Charles Chevalier introduced the first lens with combined glass elements–one convex lens fitted into another concave lens–that increased the image's sharpness and helped battle field curvature.

In the century and a half to follow, leading up to the digital revolution, lens makers and professional manufacturers added more and more lens elements to their better lenses, discovering more effective means of grinding, shaping, and polishing the glass along the way.

Even before digital photography came about, companies like Nikon incorporated computer precision into their assembly process, measuring their glass elements to incredible specificity and fitting them into equally well-designed housings.
