What is the standard GoPro sensor size? Since at least 2014, GoPro has been using a standard 1/2.3″ image sensor size in all their cameras. And they have a standard f stop (aperture) of f/2.8 in every model.

In this post, we’ll cover what this all means. And share the GoPro crop factor and equivalent mm measurement.

GoPro Sensor Size and Aperture Comparison

Because GoPro regularly releases new models, we’ve built this comparison chart to show the sensor size and f-stop of each model. We include the current Hero9 and Max and back to the classic Hero4.

Because GoPro cameras are tiny, they are limited in the possible sensor size that can easily fit in the body. As you’ll notice in the chart, every GoPro uses the smallest, standard-sized, image sensor.

GoPro Crop Factor

Based on the standard GoPro sensor size of 1/2.3″, use a crop factor of 5.62.

What is crop factor? Crop factor is used to calculate the “equivalent” focal length of a lens when compared to a 35mm (full-frame) camera.

Crop factor is also known as focal length multiplier.

How many mm is GoPro? (Equivalent)

When compared to a full frame camera, a GoPro has a focal length of 16.4 mm. And an f-stop of f15.7.

Here’s the math:

  • GoPro focal length: 2.92 mm
  • GoPro aperture: f2.8
  • Crop factor: 5.62

These specs give us the following equivalent measurements for GoPro cameras.

  • Equivalent focal length: 16.4 mm (actual focal length X crop factor)
  • Equivalent aperture: f15.7 (actual aperture X crop factor)

Note: aperture is also known as f stop.

A 16 mm lens is very wide and will capture almost everything in front of it. For detail, you’ll want your subject to be quite close. Probably not much further than the length of a standard selfie stick.

The beauty of an f stop of f15.7 is that almost everything will be in focus. This is important in a GoPro – because there isn’t any real way to adjust focus. This is especially true when used in actual action photography – like mountain biking or surfing.

From what I can tell, these specs should be true for every model since 2014. This includes Hero4 to the current Hero8 and Max cameras. Of course, depending on your math – and how you take the measurement – your focal length and aperture might vary slightly. But only by a fraction – not enough to change anything meaningful.

Sensor Size Basics

What is an image sensor? This is an electronic sensor device that detects, collects, and conveys light information used to make an image.

Types of Image Sensors: CMOS and CCD are the two primary types of digital image sensors.

What type of image sensor does GoPro use? GoPro cameras use CMOS image sensors.

Here are some common image sensor sizes:

  1. 1/2.3″ This is the standard image sensor size in GoPro cameras.
  2. 1/1.7″
  3. 2/3″
  4. CX (Nikon)
  5. APS-C 
  6. 35 mm (Full frame) This is the standard sensor size that all others are compared against. The crop factor (see above) is used to compare other sensors against this size.

Does sensor size matter? It depends.

“Think of a sensor like the sail on a boat. The larger the sail, the greater the surface area, the more wind it will catch.” ~ Dave Morrow

So according to Dave, “the larger the sensor, the greater the surface area, the more light ( photons ) it will catch.”

The best sensor size really is a balance of image quality, cost, and function. For action cameras, manufacturers generally choose the smallest image sensor to allow for a compact and durable camera.

Using a small image sensor allows GoPro to keep their cameras lightweight and portable.

very good analysis ive learnt alot. kindly update with hero 9. i wanted to know about its sensor size since its got a different megapixel. and how it stack up to these. and i heard bigger megapixel is not always good. kindly eloborate.

I'm looking to buy an full spectrum lens (allows IR light through) for a gopro hero 7. How would I know what dimensions for a new lens to buy? I get the sensor is 1/2.3 and f/2.8 but are all ccd lenses the same physical diameter?

It’s worth noting that that crop factor when applied to focal length only changes the angle of view. The lens focal length and aperture are physical characteristics of a lens. Consequently the GoPro has an equivalent angle of view to a 16mm wide angle lens on a full frame sensor, it’s actually due to its focal length of 2.92mm and physics that everything is in acceptable focus. Hope this helps.

I think that HERO Session a HERO 5 Session have a 1/3.2'' sensor, not the 1/2.3''.

Session has smaller sensor, 1/3"
