Your camera sensor’s is basically a photo-sensitive site that captures light and color. This sensor has millions of these light-capturing cavities called "photosites." The camera transforms these photosites into pixels which make up your image.

If you have a 24-megapixel camera, it means you have 24 million photosites on your sensor. So, where does a camera sensor size come into play? Keep in mind, a high megapixel doesn’t necessarily mean better image quality. Why?

Definition. Depth of field refers to the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.

A camera sensor is a piece of hardware inside the camera that captures light and converts it into signals which result in an image. Sensors consist of millions of photosites, or light-sensitive spots that record what is being seen through the lens. The size of the camera’s sensor determines how much of this light is used to create the image.

In these instances, light waves that have the electric field vectors parallel to the surface are reflected to a greater degree than those with different ...

Now that we've covered the basic considerations between large and small camera sensor size, let's get into more specific detail, including technical specs.

Considering sensor size is another way to assess the quality of your equipment. The next time you go camera shopping, remember that the sensor size is a major feature. Make sure you understand the different types of cameras and types of lenses and how those factors combine with your camera's sensor size.

Camera sensortypes

A camera’s resolution is measured in megapixels. The bigger the camera’s sensor, the bigger the photosites are to hold more megapixels, creating a clearer image.

Also extremely popular, especially amongst major brands. Not all APS-C sensors measure equally. A Canon APS-C sensor is about 22.2mm by 14.8mm while the Sony is about 23.5mm to 15.6mm.

Before we get into a camera sensor size comparison, and the difference between smaller vs larger sensor sizes, we need to answer a fundamental question: what is a camera sensor? We should know its main function before we determine anything else.

Below is a brief guide to a few of the common camera sensor sizes. Also, Benjamin Jarwoskyj shows us the resulting images from some of these different sized sensors.

Hopefully, you understand the interplay of megapixels and sensor size, so now we can jump into how size affects the quality of each shot. Don't forget that to maximize the efficacy of your sensor, you'll need to know how to clean your camera sensor properly.

2023920 — Anti-reflection coatings work by manipulating the behaviour of light as it transitions from one medium (such as air) to another (such as glass).

A larger sensor requires a larger lens to cast an image over it. Not to mention, your camera itself might have to be larger to house a large sensor. Both of these considerations can be cumbersome and just down right expensive, especially if you’re traveling or if your filmmaking style doesn’t demand it.

This article mentioned how larger sensors with wide apertures could create shallow depth of field to help your subjects stand out. But a camera's sensor is just one contributing factor when considering depth of field. We'll not only define depth of field, we'll explain what other camera settings can be manipulated to achieve amazing images.

Because a sensor stores such valuable information, if there is a large camera sensor size, more information can fit, producing better quality images than smaller sensors. The size determines what you see through your camera’s viewfinder.

As mentioned above, while megapixels measure the resolution of your image, a higher count doesn’t necessarily mean they take care of everything. A larger sensor allows larger photosites and an ability to capture low light situations compared to a smaller sensor.

About a quarter of the size of a full frame sensor. It has a 2x crop factor. The four thirds system is used solely by Panasonic and Olympus. It’s about 30-40% smaller than APS-C sensors. MFT or M 4/3 is the Micro Four Thirds System for mirrorless interchangeable lens cameras.

Inside your digital camera is a very important element: the sensor. Camera sensor size is definitely something to consider when renting or purchasing a camera. The image quality and the flexibility of what kinds of images you can capture is directly related to your camera’s sensor. So how exactly does camera sensor size matter? Let’s take a closer look.

Alyssa Maio is a screenwriter from New Jersey, now living in Los Angeles. She works as a copywriter here at StudioBinder.

Well, if you have a high megapixel count, on a small sensor, all that means is the photosites are now smaller. In good light, this works just fine. But if there is low light, the tiny photosites on a smaller sensor don’t work as well.

Camerasensors

Jarwoskyj reminds us that larger sensors are great for capturing more background around your subject. The downside is that larger sensors don't perform as well in low-light conditions. In other words, camera sensor size does matter but larger is not better in every circumstance.

Smaller sensors apply cropping to lenses while larger sensors can capture much more of the scene. This full-frame from larger sensors is your traditional 35mm film. A camera sensor and its size determines image size, depth of field, resolution, low-light performance, a camera’s physical size, and more.

A pixel is the smallest unit of a digital image that can be represented in a display device. A million pixels is the equivalent to one megapixel. So your megapixel count refers to how many of these photo-sensitive sites your sensor contains.

If you’re interested in a how to capture a shallow depth of field, or blurring the background to make your subject pop, a larger sensor is the way to go. Smaller sensors require more distance from the subject to execute this. Or, they’ll need a very wide angle lens.

How else does a camera’s sensor size affect your images? This video gets into some of the nitty gritty science behind camera sensor size.

While megapixels do matter to some degree, they’re not the end all be all of what creates a crystal clear image. The sensor size plays quite a role. Let’s quickly break it down.

This is the largest sensor size. As mentioned above, it’s the same as a 35mm film frame. There is no crop factor, so whatever you see in the viewfinder is what you’ll shoot. Images of this size often require larger-bodied cameras, and even larger camera lenses.

APS stands for active pixel sensor and it’s super popular for interchangeable lens cameras. It combines a large sensor with a moderate pixel count boosting ISO performance with a 1.3x crop factor.

We’re in a golden age of TV writing and development. More and more people are flocking to the small screen to find daily entertainment. So how can you break put from the pack and get your idea onto the small screen? We’re here to help.

Angle of view refers to how much of the frame we’ll be able to see once we take the picture. Smaller sensors have a crop factor. Take a look below. You’ll notice how the full frame (larger sensor) accommodates for much more of the image.
