A full-frame camera is a digital camera with a sensor that measures 24mm × 36mm — exactly the same size as a single frame of traditional 35mm film. That's where the name comes from.
The alternative is an APS-C sensor, which is significantly smaller (roughly 25.1mm × 16.7mm). Because a full-frame sensor has more surface area, it captures more light and detail in every shot — producing better image quality, especially in low light, and delivering shallower depth of field when you want it.
In plain terms: full-frame sensors give you more to work with. That used to come at a steep price premium, but full-frame cameras are now available across a wide range of budgets — including compact mirrorless bodies that are far more portable than the DSLRs that once dominated this category.
No matter what your hobby is, there's probably a discussion about whether size matters when considering performance. For race car driving, it's the quality of the engine. For boxing, it's how hard you can hit. For photography, it's the size of the camera sensor that can really make the difference between your stock standard photo and a Pulitzer prize-winning image.
Previously restricted to professionals due to their cost, full-frame cameras offer more dynamic range than smaller APS-C crop sensors thanks to their increased size. Read on to learn more about full-frame vs crop sensors, including why sensor size matters and which cameras are suitable for your experience level.

The easiest way to understand how the two sensor sizes compare is to think of a fishing net — the bigger the net, the more fish you can catch. It's the same with camera sensors: the bigger the sensor, the more light and detail you can capture in a single image, which is exactly why the full-frame sensor's extra surface area (compared to APS-C) translates directly into better image quality.
It's not just the size of the sensor that matters — it's the size of the pixels. A 24MP photo features 24 million pixels per image. When captured on a full-frame sensor, those pixels can be much larger than on an APS-C sensor, which has a smaller surface area to spread them across.
This difference is most evident when shooting in low-light conditions. APS-C sensors can struggle to capture enough detail without introducing noise and distortion. Full-frame sensors, however, can capture more detail across both the darker and lighter areas of a scene for a more natural-looking image.
Although advancements in photography continue to push the limits of pixel density, the fact remains — size does matter.
Top tip: Shooting in RAW format will maximise the amount of detail you can capture, giving yourself more freedom during the editing and post-production stage.
Probably the most significant selling point for full-frame cameras is their shallow depth of field. An identical 50mm f/1.8 lens on a full-frame camera vs an APS-C camera will produce a different hyperfocal distance, resulting in more background blur (bokeh).
Because APS-C sensors are cropped, any focal length is increased by roughly 1.5x — turning a 50mm lens into an effective 75mm with an aperture of f/2.7, which also affects the field of view. On a full-frame camera, these numbers remain unchanged. Just point and shoot.
Yes and no. Because of the crop factor, APS-C lenses can only expose a small portion of the full-frame sensor, dramatically reducing image quality. In some cases, the APS-C lens may not function at all when combined with a full-frame camera. Our guide to understanding digital camera crop factor explains exactly how this works and how to get the most out of APS-C lenses.
Check out our blog post on crop factor to understand the intricacies of APS-C sensors and how to get the most out of them. For a broader comparison of all sensor formats, our guide to understanding camera sensor sizes — Full Frame vs APS-C vs Micro Four Thirds is a great place to start.
Thanks to the prevalence of smartphones, practically everyone now has a camera. However, full-frame cameras have traditionally been favoured by professionals — their extra functionality and image quality came at a price that put them out of reach for beginners and enthusiasts. Fortunately, the market is now packed with relatively affordable full-frame cameras across both DSLRs and the newer mirrorless category.
Here are some of our favourite full-frame cameras for every skill level.

One of the most common questions photographers ask when upgrading their gear is: are full-frame cameras actually better? The honest answer is — it depends on what you're shooting and what stage you're at in your photography journey.
Full-frame cameras genuinely excel in a number of real-world scenarios. Because of their larger sensor size (24mm × 36mm), they gather significantly more light than APS-C crop sensor cameras. This translates directly into cleaner images in low-light conditions, better dynamic range, and more natural background blur (bokeh) — all qualities that professionals and serious enthusiasts actively seek out.
That said, 'better' doesn't always mean 'better for you'. APS-C cameras are lighter, more compact, and more affordable. They're also excellent for wildlife and sports photography thanks to the 'crop factor' magnification effect, which effectively extends the reach of your telephoto lenses. A 300mm lens on an APS-C camera behaves like a 450mm lens, giving you more reach without the cost of longer glass.
For portrait photographers, landscape shooters, videographers, and anyone working in challenging lighting environments, full-frame cameras are genuinely superior. For travel photographers, beginners, or those shooting fast-moving subjects on a budget, APS-C cameras remain a compelling option. The key is matching the tool to your creative goals — not chasing specs for their own sake.
If you're considering the switch to full-frame, the good news is that prices have come down significantly in recent years. Entry-level full-frame mirrorless cameras from Sony, Canon, and Nikon now sit at price points that were once reserved for APS-C mid-range bodies, making full-frame more accessible than ever before.
Understanding the advantages of a full-frame camera helps you make an informed buying decision rather than simply following the hype. Here are the key benefits that set full-frame sensors apart from their smaller counterparts.
The most significant advantage of a full-frame camera is its ability to perform in low-light situations. Because the individual pixels (photosites) on a full-frame sensor are physically larger, each one captures more light per shot. This results in lower image noise (grain) at higher ISO settings, meaning you can shoot confidently in dimly lit venues, at dusk, or indoors without flash — and still come away with clean, sharp images.
Dynamic range refers to a camera's ability to capture detail simultaneously in the brightest highlights and the darkest shadows of a scene. Full-frame sensors typically offer a wider dynamic range than APS-C sensors, giving you more latitude when editing in post-processing. This is particularly valuable for landscape photography, where skies can be much brighter than foreground subjects.
Full-frame cameras produce a more pronounced background blur (bokeh) at equivalent aperture settings compared to crop sensor cameras. If you're new to controlling background separation, our beginner's guide to depth of field is a great place to build that skill. This makes them ideal for portrait photography, where separating a subject from a busy background is a key creative technique.
Because a full-frame sensor captures the full image circle projected by a lens — without any crop factor — you get the true focal length the lens was designed for. This is especially beneficial for wide-angle and architectural photography, where the APS-C crop factor can make it difficult to achieve a genuinely wide perspective.
Full-frame sensors tend to support higher megapixel counts without compromising per-pixel image quality. If you want to push resolution even further, medium format cameras offer an even larger sensor than full-frame for the ultimate in image detail. This means larger prints, more flexibility to crop in post, and greater detail for commercial or fine art applications.
Together, these advantages explain why full-frame cameras remain the preferred choice for professional photographers across portraiture, weddings, landscapes, and studio work.
Video capability has become one of the most important factors when choosing a full-frame camera, and the demand for 4K full-frame cameras has surged as hybrid photo-video shooting becomes the norm. Whether you're a content creator, filmmaker, or photographer who occasionally shoots video, understanding what to look for in a 4K full-frame camera will help you get the most out of your investment.
Not all 4K is created equal. When evaluating a 4K full-frame camera, pay attention to the following:
The Sony Alpha A7 IV is one of the most popular 4K full-frame cameras available today, offering 4K 60fps oversampled from a 33MP sensor, 10-bit 4:2:2 recording, and Sony's best-in-class autofocus system. The Canon EOS R6 Mark II delivers uncropped 4K 60fps video with exceptional in-body image stabilisation (IBIS), making it a favourite among hybrid shooters. For those wanting maximum resolution alongside stunning 4K video, the Sony Alpha A7R V and Nikon Z8 offer flagship-level performance with internal RAW video recording capabilities.
Whether you're shooting short films, YouTube content, weddings, or documentaries, a 4K full-frame camera gives you the image quality, dynamic range, and creative flexibility to produce truly professional results. Explore the full range of 4K full-frame cameras at Novatech Direct in-store or online.
Yes — many mirrorless cameras are full-frame, and today's full-frame mirrorless bodies represent the mainstream choice for serious photographers. Brands including Sony (Alpha 7 series), Canon (EOS R series) and Nikon (Z series) all offer full-frame mirrorless systems with broad lens ecosystems.
Mirrorless cameras ditch the optical mirror mechanism found in DSLRs, making them lighter and more compact while retaining the same large 24×36mm sensor. The result is full-frame image quality in a smaller, quieter body.
It's worth noting that not all mirrorless cameras are full-frame — many use APS-C or Micro Four Thirds sensors. If sensor size matters to you, always check the specs before buying. Look for '35mm full-frame' or '24×36mm' in the product description to be certain you're getting a full-frame sensor.
'Full-frame' and 'mirrorless' describe two different things — sensor size and camera body type respectively — so comparing them directly is a little like asking whether a car is fast or blue. You can have a full-frame mirrorless camera, a full-frame DSLR, or an APS-C mirrorless camera.
That said, if you're weighing up a full-frame DSLR against a full-frame mirrorless body, the core image quality from the sensor will be comparable. Where mirrorless wins is size, weight, silent shooting, and advanced autofocus systems (particularly for subject tracking). DSLRs still offer longer battery life and an extensive second-hand lens market.
For most photographers buying new today, full-frame mirrorless is the practical choice — the lens ranges have matured, bodies have come down in price, and the technology continues to move forward in the mirrorless camp. For a deeper look at how the technology works, our complete guide to mirrorless cameras covers everything from sensor mechanics to DSLR comparisons.
