Build A Prime Lens Kit

Lenses with a wide aperture of ƒ/1.4 like the Nikon 50mm ƒ/1.4 have a razor-thin depth of field and can require some practice to get the focusing technique down.

If money is no object, the best option is to look into the ultrafast ƒ/1.4 primes. Most ultrafast prime lenses are built by the camera manufacturers, although Sigma has made an impressive foray into this field with some lenses that are bringing professional quality at affordable prices. These ƒ/1.4 lenses all come in at over $1,000 (except for the Sigma options), so this is probably something you would want to build toward.

Ultrafast primes are designed to be used wide open and are sharper at their maximum aperture than a typical ƒ/2.8 lens—and when stopped down a couple of stops, they’re extremely sharp. They also typically have a much more robust build quality than their slower counterparts. One drawback is that these fast ƒ/1.4 lenses can be more difficult to focus accurately due to the extremely shallow depth of field when shooting at the maximum aperture.

Sharpness. Prime lenses have simpler designs, requiring fewer glass elements and moving parts, therefore, the optical performance is typically higher. I say typically because there are some zooms just as sharp as a prime (the Nikon 14-24mm ƒ/2.8G being one example).

Speed. Again, due to simpler designs and smaller size, a prime lens can be made with a wider aperture. This gives photographers a few different advantages. It allows the use of lower ISO sensitivity settings, a shallower depth of field and faster shutter speeds in low light.

Size. Prime lens simplicity allows them to be much more compact than just about any fast zoom. While the current trend of ultrafast ƒ/1.4 wide-angle lenses are getting to be almost as big as a pro zoom, most primes in the ƒ/1.8 to ƒ/2.8 range are tiny in comparison to a fast zoom.

For those on a tighter budget, there are a lot of great options for building a prime lens collection that won’t break the bank. The best way to go is for the newer ƒ/1.8 lenses. These lenses are only about two-thirds of a stop slower than the high-end ƒ/1.4 lenses, but they’re more compact and lighter than their faster counterparts—and much less expensive. For about $1,400, you can outfit yourself with a 28mm ƒ/1.8, a 35mm or 50mm ƒ/1.8 and a 85mm ƒ/1.8. This may look pricey, but when you consider that a 24mm ƒ/1.4 is about $2,000 alone, you can see what kind of savings can be had.

Another option to consider is older prime lenses. These lenses aren’t designed with digital sensors in mind, but you can get fast lenses for a fraction of the price of the newer lenses. I do, however, recommend trying to stick with the newest lenses that are designed for digital when building a prime kit, especially if you’re using a very high-resolution camera body.

If you’re not sure you want to invest a lot of money in primes and you want to build a kit just to try out, there are plenty of options, especially in the used market. You can put together a nice kit of older ƒ/2.8 autofocus primes for well under the price of a new ƒ/2.8 zoom. You can also opt to go with manual-focus lenses, which are sometimes less expensive than autofocus lenses, but can be optically better.

Building a great set of prime lenses isn’t necessarily accomplished overnight. It’s important to assess your needs and spend your money where it will best be used. For example, I found that 35mm and 85mm are my most used focal lengths, therefore, I spent more money on those two lenses than I did on my 50mm, which is one of my least used focal lengths. And although I really wanted to buy the 24mm ƒ/1.4, I found that 24mm isn’t a focal length I use often, so instead I kept my old 24mm ƒ/2.8. The point is that you don’t have to have the abso
lute best lenses across the board. Pick and choose your primes wisely.
