Smartphone Camera Sensor Size List vs DSLR and Mirrorless Camera Sensors, Updated Regularly

Earlier today - December 26, 2017, I posted a status update on my Facebook account talking about the camera sensor size of various flagship-level smartphones - through the years - that are known for their stellar imaging and video recording capabilities.

After reading my post, some of my techy friends messaged me and told me that they were shocked to find out that some high-end handsets released more than four years ago actually had far bigger imaging sensors compared to all top-level cameraphones released within the past two years.

Nokia 808 PureView vs Apple iPhone X vs Nokia Lumia 1020 vs Sony Xperia XZ Premium vs Samsung Galaxy Note8
From top left, clockwise: Nokia 808 PureView, Apple iPhone X, Sony Xperia XZ Premium, Nokia Lumia 1020, and Samsung Galaxy Note8

To be specific, Nokia 808 PureView released in May 2012 has a sensor that's more than three times larger than what's inside the rear camera of the Apple iPhone 7 from 2016! Believe it.

Why does Sensor Size matter?

Light is the reason why we see things and it's what makes photography possible. Without light, we won't be able to see anything and a camera - no matter how powerful - won't be able to snap any image.

A camera's imaging sensor is similar to our eyes (or the back of our eyes) and its processor is like our brain. The sensor is the one that gathers light and information about the objects upon which light bounces and sends the data to the processor, which then delivers a duplicate (and often heavily tweaked) image of what's in front of the lens.

Hence, the bigger an imaging sensor is, the more light and information it can capture for better and clearer image replication.

Smartphone Imaging Sensors Are, Generally, Very Small

Camera Sensor Sizes Comparison from DSLR to Smartphones

The graphic I made above is a creative and "hardly to-scale" comparison of the sensor sizes of popular DSLR, mirrorless cameras, point-and-shoot cams, and smartphones.

Here, we can clearly see how diminutive a handset's imaging sensor is, compared to what's inside a professional DSLR or mirrorless camera. This is exactly the reason why I think Youtube videos comparing the image quality of photos and videos taken using the iPhone X compared to that of Sony a7R Mark III - for example - couldn't be fair in any way, especially in low light conditions.

If you're interested, here are camera models that have the above-mentioned sensor formats (Note that there are other sensor sizes exist in between some of these standards):

Alright! I hope you found that list useful and informative. Now, let's jump to what this blog post is truly all about: I'll give you a list of popular smartphones starting with those that have the largest imaging sensors all the way to those with relatively smaller ones.

I'll be adding more models to this list regularly -- making sure that the image sensor size noted came either from the company that made these smartphones or from reliable sources that access to verified information about these products.

Sensor Size, however, isn't all that matters.

It takes more than a sensor to take a snapshot of a moment and to make a digital copy of it. Sure, the sensor captures the light, which is essential -- but a camera is made up for multiple parts for a reason; There's the lens that adjusts and manipulates the light and information that lands on the sensor. There's also the processor that makes sense of the data delivered by the sensor. The focus sensor, on the other hand, is responsible for speed of auto-focus and the accuracy of tracking focus, in some cases. And of course, there's the imaging software - unique to each brand - that greatly determines the dynamic range, temperature, and color science of resulting images.

So if you're wondering how a handset like the Apple iPhone 7 - with its small sensor - could rank higher than the legendary Nokia 808 PureView in current imaging quality tests such as those done by DxOMark, it's only because the other elements that power iPhone 7's shooter - sensor aside - are already superior to that of Nokia's imaging beast from the Finnish Giant's hey-days.
