The cameras are getting better because the image sensors and processors are getting better, which is a big part of why smartphones are so expensive.

A crop factor is the conversion rate of a smaller sensor to reach the same size as a full-frame sensor – let me give you an example.

Hasselblad, Pentax and PhaseOne also develop medium format cameras. A popular medium format camera from Hasselblad is the X1D II 50C with a 43.8mm × 32.9mm, 50MP sensor.

Technical information and application examples including theoretical explanations, equations, graphical illustrations, and much more.

Other common photography terms you’ll hear are CMOS sensors – Complementary Metal Oxide Semiconductor, and CCD sensors – Charge Coupled Device.

Finally, much like APS-C, Micro Four Thirds system cameras are generally lower in cost – although some of the pro-level video-centric MFT models are pricey.

Full-frame sensors have many photosites across a larger space and are best for low light performance and achieving a higher dynamic range.

The simple answer is never – provided you keep a lens or body cap on the camera when it’s not in use. The image sensor is incredibly sensitive, and the slight mark, smudge or speck of dust can ruin an image.

In this case, bigger is better as medium format image sensors capture an insane amount of light and detail to produce super-high-resolution image files.

Understanding CMOS imagesensor

Finally, you’ll need optimal system requirements and memory on your computer to manage and edit these whopping images – editing apps such as Lightroom and Photoshop can crawl to a halt unless you have a powerful computer.

There’s a lot of confusion surrounding the general upkeep of sensors, whether full-frame, micro four thirds or any other camera sensor sizes.

In a bid to offer alternatives to full-frame sensors, manufacturers developed the APS-C sensor size. APS-C stands for Advanced Photo System Type-C.

A bigger body, bigger sensor and bigger processor equate to a higher cost – sometimes 2-3 times the price of a full-frame mirrorless camera.

The camera sensor is damaged if there is no sign of spots or marks on the sensor, but you’re still getting images with defects on them.

APS-H stands for Advanced Photo System Type-H with the H for High Definition and is another form of a cropped CMOS sensor. There’s also an APS-P with the P standing for Panoramic.

This sensor format is exclusive to Olympus and Panasonic cameras – many companies make MFT lenses, including Leica, Sigma and Tamron.

While full-frame is considered the gold standard of image sensors, the next CMOS camera sensor size challenges that thinking.

The short answer is it depends. Sensor size mostly depends on your budget as well as the kinds of photography you do. For serious professional work, go with Full-frame. But if you are still pretty new and still learning the ropes, go with a Micro Four Thirds or even a 1-inch sensor.

There's a lot of confusion surrounding the humble camera sensor. Find out why image sensor size is so important for photography, and what size is best for you.

One of the most important considerations is the camera sensor size – followed by the megapixel count – when camera shopping.

These sensors are 27.9mm x 18.6mm and sit between the full-frame and APS-C camera sensor size. It’s an odd size developed by Canon for their early pro-level digital cameras – the Canon EOS 1D.

I’d recommend getting your camera sensor cleaned professionally once a year. As for how to clean your camera lens, read this article.

Fujifilm is a household name for digital and film cameras and has several medium format cameras available. One of Fuji’s latest medium format camera is the GFX100S with a 43.8mm x 32.9mm, 102MP image sensor – needless to say, the RAW image files are huge and detailed.

Some camera sensors can’t produce the image quality and resolution required to print large scale photos. However, if you need a camera for family images to share on social media, a smaller sensor is best.

Modern digital medium format cameras range from 43.8mm × 32.9mm up to 53.7mm × 40.2mm. What’s more, there’s only a handful of brands that offer medium format cameras.

Most compact cameras have smaller camera sensors to fit inside their pocketable bodies. However, with the ongoing development of smartphone cameras, a new generation of tiny sensors has risen.

It’s also important to remember that some cameras have low megapixels, but the individual photosites, or pixel size, are bigger.

A Canon EOS 90D is a DSLR with a 22.3mm x 14.9mm, 32.5MP APS-C sensor – it’s a brilliant camera that’s often mistaken for one with a larger image sensor size.

Smartphone technology incorporates a variety of 1-inch sensors, and while these sensors are not ideal for low-light conditions, they produce a suitable resolution for use on social media platforms.

The sensor is cropped or cut down 1.6 times from the size of a full-frame sensor. As a result, the crop factor of the Canon EOS 90D sensor is 1.6x.

Commonly found in compacts, action cams and smartphones, the smaller sensors can still deliver great image quality and resolution.

The 1/1.7″ sensor was predominantly 12MP and far more popular – it appeared in several compact cameras from Leica, Panasonic, Nikon, Canon and Samsung.

The crop factor of APS-C is a great advantage when using telephoto lenses. A 400mm lens on a full-frame body has a 400mm focal range. But a 400mm lens on an APS-C camera with a 1.5x crop factor becomes a 600mm equivalent lens.

However, Sony is not the only one to use this sensor size. The Ricoh Theta 360 action cam and the Canon PowerShot G5 X also feature a 20.2Mp 1″ sensor.

The most popular smartphones use a variant of the 1-inch sensor range to keep size and weight to a minimum. Here’s a list of the most popular handsets available and their sensor sizes:

Given the large camera sensor size and powerful processor, the cost to produce a medium format camera is far above a typical DLSR or mirrorless camera.

APS-C dimensions are not as clear cut as seen with the 35mm full-frame sensor. Different brands have different APS-C sensor dimensions.

An MFT sensor allows a shallow depth of field with cinematic qualities, such as with the Panasonic Lumix GH5 with its 20.3MP Micro Four Thirds CMOS sensor.

An example of a full-frame DSLR is the Canon EOS 5D Mark IV that features a 30MP sensor – another is the Nikon D850 with a 45.7MP sensor.

The Micro Four Thirds system sensor is much smaller than APS-C at just 17.3mm x 13mm – the name ‘Micro Four Thirds’ comes from the sensor’s aspect ratio of 4:3.

Jan 8, 2024 — Focal length measures the distance between the optical center of a lens – the focal point where the light rays converge – and the image sensor.

You’ll know that your camera sensor needs cleaning if you can see dust or smudges on the sensor. Also, if you notice marks and soft spots on your photos, it’s a sign there’s dust on the sensor, and it needs a clean.

Medium format sensor cameras are best suited to photographers at the top of their game for fashion, portrait and commercial photography – the kind of people who have clients with high demands!

As you can see from the sensor size chart above, there are many different camera sensor sizes. Use it as a guide for sensor size comparison.

A camera image sensor is the equivalent of the human eye. It reads the available light, detail, contrast, and colour and sends the information to the processor – the human brain’s equivalent.

One thing to remember – the latest smartphones make use of computational photography (see guide) to make the most of their diminished sensor sizes. It’ll be some years before cameras can do this.

Don’t let the diminutive size of an MFT sensor put you off – highly acclaimed Panasonic mirrorless cameras feature this sensor as they’re ideal for video recording.

Another example is the Fujifilm X-T4 – a digital mirrorless camera with a 23.8mm × 15.6mm, 26.1MP APS-C sensor. The dimensions of the Fuji sensor are bigger than the Canon 90D. The crop factor on the X-T4 sensor is 1.5x.

The sensor allows a camera to turn all of that information into stunning images and precious memories, so clearly it requires some serious thought before making a decision on your next camera purchase!

To know your camera sensor’s size, check the manufacturer’s website and look for the specification for your digital camera model. It should give you the sensor size, type, dimensions and megapixel count.

Different camera sensor sizes (including APS-C) are compared to the 35mm full-frame to determine their crop factor to make things more complicated.

When capturing images with a film camera, a small shutter opens, allowing light in for a fraction of a second. The light hits the film inside the camera, and it records light, colour, contrast and detail.

What are your thoughts on the types of camera sensors available? Do you have a preference for the sensor size you prefer when shooting with a new camera?

Like any tech device, digital camera sensors will eventually wear out as the individual photosites age and cease to function. Depending on the sensor’s quality, it can last between 10,000 actions (shots) up to 300,000 and more.

You wouldn’t use these for printing anything more significant than a 6×4″ standard photo that fits into a family photo album. Although in the case of action cameras, they capture high-quality video footage with outstanding resolution.

There's a lot of confusion surrounding the humble camera sensor. Find out why image sensor size is so important for photography, and what size is best for you.

Images taken with full frame sensor cameras have a lot of image detail that can be printed or displayed on a large scale without image resolution loss.

As mentioned, many DSLRs feature these – they’re considered pro-level as they have high megapixel counts and capture exceptional image resolution. They achieve an extraordinary depth of field compared to smaller sensors, even in low light.

If you want to print a photo for a billboard, you should shoot with a 102MP medium format camera – there’s almost no limit on the image size.

A sensor houses millions of tiny light-sensitive receptors called photosites – counted as megapixels or millions of pixels.

The Sony RX100 VII is a popular compact camera with a 24-200mm built-in zoom lens. The Sony features a 1.o” sensor (13.2mm x 8.8mm) packing 20.1MP into its tiny size. The RX100 series is popular for travel as it produces excellent image quality and shoots 4K video.

A camera processor converts data from the photosites into an image and saves it to a memory card. The number of photosites on a sensor depends on several factors but can range from 16MP up to 102MP.

Due to the larger sensor format, full-frame cameras have a greater depth of field to achieve stunning bokeh and subject separation.

Let’s take a look at what a camera sensor is and how it works to record pixels – but first, a history lesson about film cameras.

When taking a photo with a smartphone, mirrorless or DSLR camera, a shutter opens to expose the sensor to the incoming light from the lens.

Also, you may notice that your images have what’s referred to as ‘dead pixels’. These are photosites that have stopped working and usually leave a random white pixel on your image.

The APS-H sensor only appeared in the five generations of the 1D, with the Canon EOS 1D Mark IV being the last model. It features a 27.9 x 18.6mm sensor with 16.1MP – not huge by today’s standards, but it’s a decade old.

Full-frame refers to a standardized 35mm sensor that replicates the size of 35mm film. That is why a lot of photographers consider this as the best camera sensor.

The smaller size of the APS-C CMOS sensors means the camera body is also smaller than a full-frame option. It also results in lower cost while still delivering superb image and video quality.

The most significant downsides of a MicroFour Thirds sensor is the poor performance in low light conditions. The size of the sensor means fewer photosites – resulting in less light captured by the sensor.

Knowing the camera sensor sizes is essential as it’ll help you understand which lenses match your camera. A full-frame camera, for example, should be paired with full-frame lenses to achieve the best optical outcomes.

Many of the best mirrorless cameras feature a full-frame sensor – the Sony a7R IV has a whopping 60.2MP full-frame sensor – a lot of pros use this camera for commercial photography and weddings.

With digital cameras, the sensor is a device that sits inside the camera and works in much the same way – it replaced the film photography process.

It matches the Advanced Photo System C (Classic) film format’s approximate size – there’s a trend of film sizes converting to sensor sizes.

One of the biggest challenges facing photographers today is agreeing on which sensor is best. Of course, there’s no one sensor to rule them all – this is not Lord of the Rings!

However, APS-C sensors are smaller with fewer megapixels, meaning they’re not as good as full-frame when shooting in low light (where you’d typically need to use higher ISO values) – for the best cameras for dark conditions, see this guide.

Photosites on the camera sensor capture the light like tiny buckets catching rain. The amount and size of the photosites determine the image quality and accurate recording of light, contrast, and colour.

Now let’s move on to something smaller – much smaller. (Even the smaller APS-C cropped sensor is large compared to these sensors.)
