Prime lenses are awesome. If you don’t know what makes prime lenses so great, you will after this post.<\/p>\n

A Primer on Primes<\/h2>\n

A prime<\/em> is a lens with a single focal length<\/strong>. Unlike a zoom<\/em> lens, the only way you get closer to or farther from your subject when using a prime lens is by moving the camera itself<\/strong>.<\/p>\n

Prime lenses are referred to simply by their focal length. For example, 25mm, 35mm, 50mm, and 85mm are all common focal lengths for prime lenses and is how they are generally referred to as well.<\/p>\n

You may have heard of lenses referred to as a “nifty-fifty”<\/em>, a “thrifty-fifty”<\/em>, or perhaps simply as a “normal lens”<\/em>. These all refer to a 50mm prime lens<\/strong>, one of the most popular prime lenses because its field of view closely matches what our eyes see.<\/p>\n

Note:<\/strong> A 25mm prime lens would be a “normal” lens on the Panasonic GH4 with Micro Four Thirds’ 2x crop factor. “Nifty-Twenty-Five”<\/em> doesn’t quite have the same ring to it though.<\/p>\n<\/div>\n

Now that you know what a prime lens is, let’s talk about the top 5 reasons why<\/em> you should be using primes on the Panasonic GH4.<\/p>\n

1. Primes are Simple<\/h2>\n

Relatively speaking, primes have a simpler construction since the internal lenses do not need to move to adjust focal length. Fewer components and moving parts means prime lenses are lighter and less prone to image quality issues such as chromatic aberrations, fringing, and flare.<\/p>\n

\"Moving<\/a>

However, using<\/em> prime lenses is where their simplicity really shines.<\/p>\n

A prime lens is not a catch-all lens. Instead of the wide range of focal lengths you have with zoom lenses, the single focal length of a prime lens gives you one option<\/strong> when composing a shot. This is one less decision you have to deal with when shooting, allowing you to focus more on getting great shots that tell a compelling story.<\/p>\n

Furthermore, different focal lengths and apertures will be better suited to different types of shots. A lot of the fun of using primes is discovering which focal length and aperture work best for the energy and emotion you want to infuse into a shot. Once you learn what works best for a specific type of shot, shooting gets even simpler.<\/p>\n

\n

Bottom line:<\/strong> Prime lenses don’t burden you with a mountain of options when deciding how to compose a shot. With only one focal length, the choice is simple.<\/p>\n<\/div>\n

2. Primes are Small<\/h2>\n

Fewer components in prime lenses means that they are smaller and lighter than zoom lenses.<\/p>\n

\"Prime<\/a><\/p>\n

Which lens would rather heft around all day? Smaller lenses also mean you can fit more primes in your camera bag– so you have the right lens for each shot– without being weighed down.<\/p>\n

\n

Bottom line:<\/strong> When you want to be light and mobile, use primes.<\/p>\n<\/div>\n

3. Primes are Fast<\/h2>\n

Thanks to their simpler construction, prime lenses are often faster than zoom lenses– a lot faster<\/strong>.<\/p>\n

\n

Note:<\/strong> A lens’ speed refers to the size of its aperture. A “fast” lens has a large aperture.<\/p>\n<\/div>\n

\"Aperture<\/a>

Prime lenses with large apertures from f\/1.4 to f\/2.0 are quite common for prime lenses.<\/p>\n

\"Fast<\/a><\/p>\n

Even faster primes with apertures from f\/0.95 to f\/1.2 are not unheard of.<\/p>\n
