Guide to Sony Alpha Full-frame Mirrorless Cameras

Sony's full-frame mirrorless cameras have something for every type of photographer and video shooter. Choosing the right one can feel a little intimidating, so we're going to break down the Alpha full-frame series to help you find the best fit.

What are Sony full-frame cameras?

A full-frame camera uses a sensor that's the same size as 35mm film, with improved low-light performance, greater dynamic range and a shallower depth of field compared to APS-C cameras. Because Sony's full-frame cameras are mirrorless, they're generally lighter and more compact than traditional DSLRs.

One of the best things about Sony's full-frame mirrorless cameras is the huge choice of Sony FE lenses. You can pick up a Sony lens or opt for one from a third-party brand like Sigma, Tamron or Samyang, and it'll work across the whole full-frame Alpha range. That means if you decide to upgrade to another Sony full-frame camera in a few years, your lenses can come with you.

About this guide

Choosing between 22 Sony full-frame cameras isn't easy. In this guide, MPB camera expert Amy Moore shares her experience of shooting with Sony cameras for more than a decade, including taking over 15,000 images on the Sony A7 III alone.

Amy looks at every Sony full-frame camera released to date, with additional insight from MPB Videographer Jakub Golis, whose experience spans Canon DSLRs, Sony Alpha cameras, Sony cinema cameras and RED systems. The guide was edited by Laura Milner.

Understanding Sony's full-frame lineup

Sony's full-frame camera range started small, with the original Sony A7 in 2013, then expanded into specialised lines for different types of photographers. I've organised Sony's full-frame cameras by series, making it easier to compare similar models and find the right one for whatever you need it for. Not sure where to start? Here's the short version.

A1 series (2021–)

If you want the very best from Sony, the A1 series is where you'll find it. These flagship cameras are all about speed, resolution and video. 

Since the original Sony A1's launch, the series has continued to blossom. Sure, there are only two cameras in the lineup, but one is faster and smarter than the other.

Sony A1 (2021)

Typical used price: £1,300–£3,200

The original Sony A1 is at home in almost any genre, but it thrives in sports and wildlife photography, landscapes, portraits and commercial work. 

Pros

• Speed, resolution and video in one camera

• Excellent autofocus and subject tracking

• Lots of detail for cropping and large prints

Cons

• Costly if you’re on a tight budget

• Files demand a lot of storage

Its autofocus is still good, and the 50 megapixel sensor means you have the flexibility to crop into images without making your images look rubbish. Take a look at Marc Read’s in-depth Sony A1 review, where he tested it photographing wildlife and aircraft.

Sony A1 II (2024)

Typical used price: £3,000–£4,900

If you had a Sony A1 II in one hand and a Sony A1 in the other, it’d be very difficult to tell them apart. Rather than starting from scratch here, Sony added some improvements to autofocus, image stabilisation (IBIS) and handling. 

Pros

• Strong all-round performance

• Good for both photo and video

• Sony's latest autofocus system

Cons

• Premium price tag

• A modest upgrade from the A1

The A1 II is even more costly than the Sony A1, so if you're a hobbyist, it's not the camera for you. But if you want the all-singing, all-dancing A1 model and you’re a professional, knock yourself out. To see how the two compare and explore the kind of images you can produce with the A1 II, check out our Sony A1 II review. 

A7C series (2020–)

If you love good image quality but don't want to carry a heavy kit, there’s a Sony A7C series for that. The "C" stands for compact, and you’ll find full-frame performance in these three smaller, lighter bodies. The A7C series is the series for those who travel and shoot or take photos every day.

The biggest differences from the standard A7 series are the compact design and the snazzy, rangefinder-inspired body. There really isn’t much to separate them in terms of image quality. 

Sony A7C (2020)

Typical used price: £500–£820

The Sony A7C is evidence that full-frame cameras don’t have to be big and bulky. Yes, the newer and shinier A7C II and A7CR have even better autofocus, image stabilisation and resolution, but the original is still a great camera. It’s also a more affordable way into Sony’s compact full-frame range.

Pros

• Small, lightweight and easy to travel with

• Great image quality

• Excellent value bought used

Cons

• Older autofocus than the newer A7C models

• Only 8-bit video

• Single memory card slot

The Canon EOS R6 and the A7C are two popular choices for photographers looking for a compact, versatile full-frame camera. Gess Puglielli compares them in our Canon EOS R6 vs Sony A7C comparison for low-light photography.

Sony A7C II (2023)

Typical used price: £700–£1,300

The Sony A7C II took the idea of the A7C and A7CR, then ran with it, throwing in a higher-resolution sensor, faster autofocus and even better image stabilisation. If you shoot both stills and video, you’re always on the move, or you like to travel light, take a punt with the A7C II. It’s a solid addition to your packing list alongside your passport.

Pros

• Small, light to travel with

• Fast autofocus

• Balance of photo and video features

Cons

• Single memory card slot

• Smaller grip

• Cropped 4K, 60p

It shares much of Sony A7 IV’s performance thanks to the same 33-megapixel sensor, but the body is (obviously) much easier to carry around. To prove it’s a good travel buddy, here’s our Sony A7C II travel camera review.

Sony A7CR (2023)

Typical used price: £1,100–£1,900

The Sony A7CR is what you want if you’re fond of the A7C's compact size but need more resolution. It takes the renowned 61 megapixel sensor from the A7R series and somehow manages to make it work in a travel-friendly body. This makes it the choice for those of you who want to pack light while packing detail into your images.

Pros

• Huge 61 megapixel resolution in a compact body

• Outstanding autofocus and image stabilisation

• Great for travel and landscape photography

Cons

• Single memory card slot

• Smaller viewfinder than the A7R V

The A7CR has a much higher-resolution sensor, improved AI-powered autofocus and better image stabilisation. It's for landscape, travel, and street photographers, or anyone who prefers to crop their photos later. We took it to Mexico to test it out on street scenes and landscapes. Read Ian Howorth’s full Sony A7CR review to see how it deals with hot, low-light conditions in faraway places.

Sony A9 series (2017–)

If you need speed, the Sony A9 series is the place to start. Built with sports, wildlife and news photographers in mind, these cameras can lock onto fast-moving subjects.

The series introduced Sony's stacked sensor technology, allowing faster burst shooting and a blackout-free viewfinder, so you can keep your subject in sight. The Sony A9 III went a step further with a global shutter sensor, but more on that in a minute.

Sony A9 (2017)

Typical used price: £430–£1,000

The Sony A9 might be the oldest camera in the series, but don't write it off. It was revolutionary when it launched, and it's still incredibly quick today. Better yet, it won't stretch your budget too far, and you'll still get to experience the stacked sensor technology that made the A9 such a landmark camera. 

Pros

• Fast, reliable autofocus

• Blackout-free burst shooting

• Excellent value bought used

Cons 

• Older handling and connectivity than the A9 II

• No global shutter like the A9 III

Our Sony A9 model overview covers a few more details.

Sony A9 II (2019)

Typical used price: £590–£1,400

The original A9 was such a hit with sports photographers that Sony decided to build on that with the Sony A9 II. They gave it a tougher body, improved connectivity and refined its shape, meaning another camera for fast action joined the line-up. 

Pros

• Built for fast-moving subjects

• Dependable autofocus and burst shooting

• Excellent value on the used market

Cons

• Minimal upgrade on the A9

• No global shutter technology

Unsurprisingly, the A9 II is great for wildlife and news photography, too. It doesn’t have the Sony A9 III's global shutter (or its price tag), but it's a brilliant used buy if you’re not bothered about the latest model and still a camera that can keep up. Sports photographer Daniela Porcelli took the Sony A9 II as a plus one to the UEFA Women's Euros, and covered its perks in our Sony A9 II review.

Sony A9 III (2024)

Typical used price: £2,200–£3,600

The Sony A9 III lives life in the fast lane. It was the first-ever full-frame camera with a global shutter sensor, eliminating rolling shutter distortion completely and making split-second moments easier to capture.

Pros

• Global shutter eliminates distortion

• Impressive speed

• Outstanding autofocus

Cons

• Premium price

• Resolution won't suit everyone

The A9 III doesn't come cheap, but if sport, wildlife or breaking news is what you do, I’d say this fast action camera is worth every penny. Wildlife photographer Jordi Woerts proves that with his beautiful photos of birds in this Sony A9 III review.  

Sony A7S series (2014–)

The A7S series is made for people who spend more time filming than taking photos. The "S" stands for sensitivity, and the series is known for excellent low-light performance and video features. 

Sony A7S (2014)

Typical used price: £200–£480

"The Sony A7S only has 12 megapixels?!" you ask. Yes, 12 megapixels may seem low, but Sony knew exactly what it was doing here. By keeping the resolution low, it created a camera that could practically see in the dark, quickly turning it into a favourite with filmmakers and low-light shooters. 

Pros

• Budget entry to Sony's video lineup

• Fantastic low-light image quality

• Compact full-frame body

Cons

• Older autofocus system

• 12 megapixel resolution won't suit everyone

• 4K video quality only achieved with an external recorder

If you’re a professional filmmaker, perhaps think again, as you’ll need an external recorder if you want to achieve the sharpest possible video (4K). Additionally, if huge prints and heavy cropping are part of your workflow, this probably isn't the camera for you. 

But if you regularly film YouTube content or concerts? Go for the A7S. It's a cheaper way into Sony's video-focused lineup. Read our Sony A7S model overview to explore its full specifications.

Sony A7S II (2015)

Typical used price: £290–£700

Since the Sony A7S II ended up filming parts of Planet Earth II, Sony was probably doing something right here. The Sony A7S II helped capture some of the series' night-time sequences, giving you a good idea of what it's capable of in low light. Internal 4K recording and 5-axis image stabilisation were added, making it an even stronger choice for filmmakers than the original A7S.

Pros

• Excellent low-light performance

• Strong video features for its age

• Great value bought used

Cons

• Older autofocus system

• Only 8-bit video recording

• Short battery life

The A7S II is ideal for weddings, documentaries and filmmakers on a budget. Its price isn't too scary these days, either.

Sony A7S III (2020)

Typical used price: £1,300–£2,100

Sony clearly wanted the Sony A7S III to be one of its best flagship video-focused full-frame cameras. It packed it with features like 4K recording at up to 120fps, 10-bit colour and excellent autofocus, alongside the low-light performance the A7S series is known for.

Pros

• Strong video performance

• Excellent low-light image quality

• Great autofocus for video

Cons

• Lower resolution for still photography

• Premium price, even when bought used

If video is your priority, this is the A7 body to buy. We challenged filmmaker Teja Lisjak to spend 24 hours photographing London with the A7S III, and she proved that it's just as good for photography as it is with the record button. Here’s her Sony A7S III review.

Sony A7R series (2013–)

Some photos deserve every bit of detail you can capture. Enter the Sony A7R series. The "R" stands for resolution, with these cameras designed for photographers who regularly shoot landscapes, studio work, commercial projects or anything destined for a large print.

The extra megapixels in this series free you up to crop and pull out the finer details. The trade-off is larger file sizes, so get your memory cards at the ready.

Sony A7R (2013)

Typical used price: £210–£500

The original Sony A7R came onto the scene in 2013 with a 36.4 megapixel full-frame sensor and no optical low-pass filter. It caught the attention of landscape and studio photographers who wanted as much detail as they could squeeze from a compact mirrorless camera.

Pros

• Excellent image quality

• Compact for a full-frame camera

• Great value bought used

Cons

• Slower autofocus than later models

• Older battery and handling

The Sony A7R is still best suited to slower, more considered photography, like landscapes, architecture, still life or portraits. The autofocus and battery life feel dated compared to newer Sony cameras, but if you're buying your first full-frame body, you may not even notice. It's an affordable entry point to Sony's high-resolution lineup, and it’ll give you lots of room to grow.

Sony A7R II (2015)

Typical used price: £320–£620

Don’t be fooled by the Sony A7R II's age. 2015 may feel like a distant memory, but photographers were very happy with its beautifully detailed images when it launched. This was a huge step forward for the A7R series, introducing a new 42 megapixel sensor, much faster autofocus and the type of low-light performance that gave A7R owners reasons to upgrade.

Pros

• 42 megapixel image quality

• Better autofocus than the original A7R

• Great value bought used

Cons

• Older battery and single card slot

• Slower than newer A7R models

Landscape photographer Kilian Schönberger, who has a colour vision deficiency, uses the Sony A7R II to photograph the forest floors of his native Germany. He shows off some of his frankly outrageous shots in Forest Photography: Top 10 Photo Locations in Germany.

If you're buying it used today, the A7R II is another handy entry point to Sony's high-resolution lineup. You won’t have to worry about stretching your budget to Sony A7R V heights, either.

Sony A7R III (2017)

Typical used price: £480–£920

It was 2017 when Sony's high-resolution cameras hit their stride. The release of Sony A7R III saw no change to the A7R II’s 42 megapixel sensor (remember: you’ll need to look later in the A7R range if you want those 60 megapixels), but it still meant fast autofocus that can steady fast-moving subjects, handy dual card slots, quicker continuous shooting and reliable battery life.

Pros

• Excellent 42 megapixel image quality

• Big improvements to battery life and autofocus

• Great value

Cons

• Lower resolution than newer A7R models

• Older menu system

Wildlife conservation biologist and underwater photographer Kaushiik Subramaniam uses the Sony A7R III to photograph marine life. In his 10 Tips for Underwater Wildlife Photography guide, you’ll find out how he squeezes the most out of it (and why he prefers shooting with it over a GoPro). 

The A7R III is also well-suited to landscapes, portraits and commercial work. Thinking it could be your next camera? Our Sony A7R III model overview will help you decide.

Sony A7R IV (2019)

Typical used price: £800–£1,500

The Sony A7R IV was a big brand moment for Sony because this is where the 61 megapixel sensor was introduced. It continues to underpin the latest A7R models, making it a strong choice if you regularly crop your images. 

Pros

• Superb 61 megapixel image quality

• Great autofocus and dynamic range

• Flexibility for cropping

Cons

• Large file sizes

• Newer autofocus systems are more capable

Wildlife photographer Sasan Amir uses the Sony A7R IV to take incredible images of animals around the world. You can see more of his work in our MPB Meets: Wildlife Photographer Sasan Amir interview, where he shares his creative process and tips for getting started in wildlife photography.

If landscapes, studio photography or large prints are your thing, the A7R IV is a great shout. Building on the autofocus perks of previous A7R models, it’s an all-rounder that’s perfectly paired with fast-moving subjects. If you want to dive into the specs, our Sony A7R IV model overview covers everything you need to know.

Sony A7R IVA (2021)

Typical used price: £830–£1,400

Next up: the Sony A7R IVA, which is a barely noticeable revision of the Sony A7R IV. It does have a higher-resolution rear screen (1.6x more dots) and improved Eye AF, so if you want to take excellent high-resolution images and this one’s in your budget, don’t let the fact that it’s not much of an improvement stop you.

Pros

• Superb 61 megapixel image quality

• Improved screen and autofocus over the A7R IV

• Good for studio and commercial work, landscapes

Cons

• Only modest updates over the A7R IV

• Large file sizes

Animal photographer Yana Wernicke used the Sony A7R IVA while photographing at an animal sanctuary. You can see more of her work in our MPB Meets: Yana Wernicke interview, where she also shares her top tips for getting started in animal photography.

Sony A7R V (2022)

Typical used price: £1,000–£2,000

So you want detail? Here’s the Sony A7R V. The 61 megapixel sensor stayed put, but autofocus, image stabilisation and handling were ramped up.

Pros

• Incredible image detail

• Excellent image stabilisation

• Plenty of flexibility for cropping

Cons

• Large file sizes

• More resolution than many photographers need

It’s a good companion when photographing landscapes, portraits or commercial work. Landscape Photographer Jude Allen took it to Banff National Park to test it on sweeping mountain landscapes and handheld shots in low light. Read his full Sony A7R V review and see how it got on.

Sony A7 series (2013–)

The A7 series is the class favourite, and the best place for most photographers to start. These cameras have it all: image quality, autofocus, video features, reasonable used prices and, really, they’re the foundation of Sony's Alpha lineup.

Since the original A7 launched in 2013, each generation has improved on the last. The A7 II introduced in-body image stabilisation, the A7 III brought a huge leap in battery life and autofocus, while the A7 IV and A7 V are meant for today’s photographers who like to shoot video, too.

Sony A7 (2013)

Typical used price: £140–£330

Before the A7R, A7S, A9, A7C and A1, there was simply... the Sony A7. It's the camera that started Sony's full-frame mirrorless story and laid the foundations for everything that followed.

Pros

• Affordable entry into Sony full-frame

• Lovely image quality

• Compact and lightweight

Cons

• Older autofocus system

• No in-body image stabilisation

• Short battery life compared to newer A7 models

The Sony A7 is the camera for you if you take photography at a slower pace. Ideal for travel photos or portraits, it can still produce lovely images, but remember: autofocus and battery life have come a long way since 2013. I still think the Sony A7 is a great starting point. Think of it as a budget-friendly way into Sony's full-frame system, leaving you with more money to spend on the lenses you can use for years.

Sony A7 II (2014)

Typical used price: £260–£490

The Sony A7 II introduced 5-axis in-body image stabilisation to the A7 series, so handheld shooting was suddenly a breeze. A more comfortable grip and noticeably improved handling also helped the series feel far more polished.

Pros

• Budget-friendly entry into Sony full-frame

• 5-axis in-body image stabilisation

• Comfortable handling

Cons

• Older autofocus system

• Short battery life compared to newer A7 models

The A7 II is a wallet-friendly way into Sony's full-frame system. Just bear in mind that autofocus and battery life are much better these days, so you probably won't be photographing cheetahs with the A7 II, and you'll want to pack a few spare batteries. Find out more in our Sony A7 II model overview.

Sony A7 III (2018)

Typical used price: £480–£910

The Sony A7 III cemented the A7 series as Sony's all-rounder range. It brought the larger NP-FZ100 battery from the Sony A9 series, significantly improved autofocus and added dual card slots. It's particularly well-suited to weddings, events and travel photography.

Pros

• Good value 

• Great battery life

• Reliable autofocus

Cons

• Older video features than the A7 IV and A7 V

• No fully articulating screen

The A7 III is one of the best-value full-frame cameras you can buy used. I can vouch for that because mine has stayed in my camera bag for years. If you want to see why I keep coming back to it, take a look at my Sony A7 III review, where I fight its corner.

Sony A7 IV (2021)

Typical used price: £940–£1,500

With stronger video features and a more refined design than the Sony A7 III, the Sony A7 IV was built for photographers and filmmakers who like to switch between stills and video.

Pros

• Excellent all-round performance

• Great autofocus for photo and video

Cons

• More expensive than the A7 III

• 1.5x crop in 4K 60p video mode

Whether you're travelling, shooting weddings or creating content for clients, it's a versatile full-frame camera that won’t waver, whatever you throw at it. It is a little more expensive than the Sony A7 III, though, so I'd only recommend upgrading if video is a big part of what you do, or you want Sony's newer autofocus system. 

Commercial photographer Jacob Murray visited the Dolomites in Italy to compare the A7 IV to the Canon EOS R5. Read his full Sony A7 IV review to see why he thinks Sony’s FE mirrorless system comes out on top. 

Sony A7 V (2025)

Typical used price: £1,400–£2,300

The Sony A7 V is essentially a smarter version of the Sony A7 IV, with AI-powered autofocus, improved video features and a faster processor. It's another all-rounder for photographers and filmmakers, making it ideal for weddings, travel, family life and content creation.

Pros

• Sony's latest autofocus technology

• Excellent all-round performance

Cons

• Premium price

• A modest upgrade over the A7 IV

The A7 V is for you if you're buying your first Sony full-frame camera and want the latest technology. It’s the premium option in the A7 family, so if you already own an A7 IV and you're on a tight budget, I wouldn’t bother rushing to upgrade.
