Guide to external microphone for camera

Videographers and vloggers quickly realize that a built-in camera microphone falls short in both audio quality and directionality. To better control the sound your audience hears while minimizing ambient and background noise, an external microphone for camera is essential. In today’s article, we offer a complete guide to this audio gear, exploring:

• Why do you need an external camera microphone?
• What are the types of camera microphones?
• How to choose the best one?
• What is the best external microphone for camera?

Why do you need an external camera microphone?

An external microphone for camera is essential because the built-in one is not ideal for capturing good sound. The built-in mic picks up a wide range of noises, which often leads to poor audio quality. Additionally, it is usually located near the lens, so it can capture sounds like the autofocus motor or other camera noises.

External microphones can be placed closer to the subject, providing clearer sound, and they are not affected by camera noise, making them perfect for capturing high-quality audio.

What are the types of camera microphones?

Before we explore the best microphones for cameras, it’s important to understand the three main types of external mics. There is no single best option, as the right choice depends on your specific needs and preferences.

Lavalier microphones: Small mic clipped on the lapel of talents, available in wired and wireless versions

A lavalier microphone for camera is a small condenser mic that attaches to the lapel, keeping it close to the speaker’s mouth. It’s also known as a tie-clip mic. They are the common choice for TV hosts and interviewees because they are discreet and offer excellent audio quality.

Lav type is highly portable and convenient, with both wired and wireless options available. Wireless lavalier microphones are favored by creators for their hands-free use. However, they can become expensive if you’re recording with multiple people, as you’ll need enough mics for everyone.

Shotgun mic: Highly directional option to capture clear and block background noises

Shotgun microphones can be mounted on a DSLR or attached to a boom pole if needed. They are very versatile and simple to use, making them a popular choice. These mics are known for being “highly directional” because their long, tube-like design allows them to capture sound from a distance.

Handheld microphone for camera: Classic mic held by hand, additional devices needed for camera recording

A handheld microphone is the classic type most people picture. It is ideal for creators who like to hold a mic while speaking. However, using it with a DSLR requires extra recording equipment, which may not be the best choice for those with a limited budget.

How to choose the one: 6 factors to consider

Choosing the right external microphone for video camera depends on several key factors. To find the best fit for your needs, consider these six important aspects.

Budget: Decide how much to cost on the external microphone for camera to narrow down options

First, you should decide how much you want to spend on audio gear for your camera. This can help you focus on choices that offer the best value within your budget.

Type & mounting style: Decide the type based on recording contents and ensure compatibility

Next, you need to decide on the type of microphone that best suits your filming setup and recording style. For example, if you frequently shoot interviews, a lavalier mic is likely the best choice for you.

If you prefer using an on-camera microphone, make sure it’s compatible with your DSLR. Check the type of connector or microphone input your camera supports. Most microphones connect via a 1/8” (3.5mm) jack, so ensure your camera is compatible with this type of connection.

Polar Pattern: Consider what directions of sounds to capture

Thirdly, think about which directions you want to capture sound from and choose the right polar pattern. A microphone’s polar pattern indicates the main directions from which it captures sound. There are three common polar patterns: Cardioid, Bidirectional, and Omnidirectional.

A cardioid pattern captures sound primarily from the front, reducing noise from the sides and back of the mic. This is ideal when recording a single, focused sound source.

A bidirectional pattern picks up sound from both the front and back while minimizing noise from the sides.

An omnidirectional microphone for camera captures sound from all directions.

Additionally, there are hyper and super-cardioid patterns, which are variations of the cardioid pattern, offering a more focused pickup from the front of the mic.

Condenser vs Dynamic: Condenser microphone for camera good at capturing high frequency sounds while dynamic one ideal for loud sounds

The main difference between condenser and dynamic microphones lies in their sensitivity and power needs.

Condenser microphones are ideal for capturing fine, high-frequency sounds, making them great for studio use. However, they tend to be less durable and require an external power source to function.

Dynamic microphones, on the other hand, are designed to capture loud sounds and perform well in noisy environments. They do not need an external power source to operate.

Frequency response: It depends on what range of audio you want the mic to capture and reproduce

When choosing a microphone for DSLR camera or mirrorless camera, the frequency response is also a key factor and defines the range of sounds it can pick up and reproduce. This range directly impacts the quality and character of the sound your mic produces. While most options cover a frequency range from 20Hz to 20kHz, some are designed to filter out very low or high frequencies to enhance the overall audio quality of your recording.

Size & weight: Consider portability if you use microphone for camera recording on the go

Finally, you should check the size and weight to ensure the portability of the external mic. If you’re shooting on location or filming vlogs while on the move, you’ll want an audio gear that’s lightweight and compact, without adding extra bulk to your setup. Also, consider the mic’s build quality and durability. If you’re frequently on the go, you don’t want a fragile mic that could easily break.

FAQs

Here are some frequently asked questions about external microphones for cameras to help you better understand their use and selection.

How can I record audio with my camera?

You can record audio with your camera if it has a built-in microphone. If not, you’ll need to connect an external microphone and switch it on. Once that’s done, just start filming. The camera will capture both video and audio simultaneously and save them to your SD card.

Can I Connect a Wireless Microphone to My Camera?

Yes, you can do this by using a dedicated wireless system designed for cameras. These systems include a small, battery-powered receiver that can be attached to the camera’s hot shoe. The receiver doesn’t use the hot shoe’s contact points but connects directly to the camera’s mini-jack input. You can choose from wireless systems with either a handheld mic or a clip-on lavalier mic, depending on your preference.

How to connect microphone to camera?

Most microphones attach to the camera’s hot-shoe port on top, either directly or with an adapter. They also connect via the camera’s headphone jack.
However, some microphones don’t need to be mounted on the camera. You or your subject can hold them, or they can be positioned on a pole outside the shot. Additionally, wireless microphone systems don’t require a wired connection to the camera. The setup depends on your preferences and the features you need, but be sure to check that the microphone is compatible with your camera model.
