10 best mirrorless cameras in 2016

Which is the best compact system camera? We rate the best CSCs by price, features and value

Best mirrorless compact system camera

Once upon a time, keen photographers bought a DSLR – it was the established order of things. But the mirror mechanism of a DSLR is complex and noisy and adds to the weight of the camera, and that's where the mirrorless camera, or compact system camera comes in. They keep the big sensors and interchangeable lenses of DSLR cameras but ditch the mirror to produce a smaller, lighter and simpler camera.

In fact, there are still pros and cons to both designs. If you want to find out more, read this: Mirrorless vs DSLR cameras: 10 key differences.

Some mirrorless cameras have a compact, rectangular body, some are styled like DSLRs with a 'pentaprism' on the top – though this houses an electronic viewfinder rather than the optical viewfinder you get with a DSLR.

Be aware, too, that cheaper mirrorless cameras don't come with viewfinders at all – instead, you compose the photo on the rear screen, just as you do with a compact camera or a smartphone. (If you're still not sure what kind of camera you need, read our easy to follow guide: What camera should I buy?)

No two photographers are exactly the same – we're all looking for slightly different things, so we've ranked the 10 best compact system cameras you can buy right now based not just on specs, handling and performance, but size, simplicity and value for money too.

Fuji X T10

1. Fuji X-T10

The X-T10 makes access to Fuji's terrific X-mount system affordable

Sensor size: APS-C | Resolution: 16.3MP | Viewfinder: EVF | Monitor: 3-inch, 920,800 dots |Maximum continuous shooting rate: 8fps | Maximum video resolution: 1080p

Excellent build and design
Value for money
High ISOs are JPEG only
Lacks X-T1's weatherproofing

At first sight the X-T10 just looks like a lower-cost alternative to Fuji's flagship DSLR-style X-T1, and you might be expecting a whole bunch of compromises as a result. In fact, though, the X-T10 uses the same sensor and Fuji's latest AF technology, which the X-T1 needs a firmware update to match. The X-T10 has a slightly smaller viewfinder image and simplified external controls which don't match the retro appeal of the X-T1's, but apart from that it's hard to see any major benefit to the X-T1 that could justify the big price difference. We love the compact DSLR-style body, the superb Fuji image quality and film simulation modes, and Fuji's growing range of premium lenses. This is top-quality mirrorless technology at a mid-range DSLR price point.

Olympus OM D E M10 II

2. Olympus OM-D E-M10 II

The brilliant E-M10 II ticks boxes you probably didn't even know about

Sensor size: Micro Four Thirds | Resolution: 16.1Mp | Viewfinder: EVF | Monitor: 3-inch tilting display, 1,037,000 dots | Maximum continuous shooting rate: 8.5fps | Maximum video resolution: 1080p

Compact size, lenses too
Excellent viewfinder
Smaller sensor than some
Pricier than original E-M10

It's a close-run thing between this and the X-T10 for the top spot in our list. We loved the original E-M10 for its size, versatility and value for money, but the E-M10 II adds features that take it to another level. The old camera's 3-axis image stabilization system has been uprated to the 5-axis system in Olympus's more advanced OM-D cameras, the viewfinder resolution has been practically doubled and the continuous shooting speed, already impressive at 8fps, creeps up to 8.5fps. Some will criticise the smaller Micro Four Thirds sensor format (roughly half the area of APS-C) but the effect on image quality is minor and it means that the lenses are as compact and lightweight as the camera itself. It's small, but it's no toy – the E-M10 II is a properly powerful camera.

Sony A7R II

3. Sony A7R II

Sony's highest resolution full-framer is going down a storm

Sensor size: Full-frame (35.9x24mm) | Resolution: 42.4Mp | Viewfinder: EVF | Monitor: 3-inch TFT LCD with 1,228,800 dots | Maximum continuous shooting rate: 5fps | Maximum video resolution: 4K

Huge, high quality images
Excellent quality viewfinder
Needs a faster AF point settings
Tilting rather than vari-angle screen

Although the first wave of Sony's Alpha 7 full-frame compact system cameras (CSCs) grabbed our attention, the second wave has really got photographers talking - especially the mighty Alpha 7R II. Some attribute the rise in popularity of CSCs in countries that had previously largely ignored them to the launch of the series. So why all the fuss? Well despite being small enough to fit in unnoticed amongst other CSCs, the Alpha 7 series of cameras have a full-frame sensor. That means the sensor is the same size as a piece of 35mm film, which is good news for image quality and depth of field control.

The A7R II has proved especially popular because it has a pixel count of 42.2 million, so it generates huge images that have bags of detail, and noise is controlled well. What's more, it can also shoot high quality 4K footage and there are lots of professional-level video features available. In addition, there's an excellent stabilisation system and Wi-Fi/NFC technology built-in so you get sharp images at lower than normal shutter speeds and you can share them quickly via a connected smartphone.

Fuji XPro2

4. Fuji X-Pro2

Classic styling houses a stack of features aimed at the enthusiast photographer

Sensor size: APS-C | Resolution: 24.3MP | Viewfinder: EVF & Optical | Monitor: 3-inch, 1.62m dots | Maximum continuous shooting rate: 8fps | Maximum video resolution: 1080p

Clever viewfinder
Very good detail and colour
Fixed rear display
EV dial easily knocked

If you're looking for a premium and stylish looking camera that can back this up with refined handling and stunning image quality, then the X-Pro2 should definitely be at or towards the top of your list. Building on the original X-Pro1, Fuji's first mirrorless camera, the X-Pro2 may look similar, but they're quite different beasts. Its the first Fuji X-Series camera to use the new 24.3MP APS-C sensor with the company's X-Trans filter array, delivering excellent colour and detail. There's also an new X Processor Pro image processing engine that sees burst shooting up to 8fps and a much improved and snappier AF system. Unique to mirrorless cameras is the X-Pro2's Advanced Hybrid Multi Viewfinder, that offers both the option of an EVF and optical viewfinder, as well an Electronic Rangefinder feature that overlays a small version of the electronic finder in the corner of the optical one. One of the more expensive options out there, but you'll be rewarded with a great shooting experience and pin-sharp images.

Sony A6300

5. Sony A6300

Forget any worries about slow focusing with this little beaut

Sensor size: APS-C | Resolution: 24.2Mp | Viewfinder: EVF | Monitor: 3-inch TFT LCD with 921,600 dots | Maximum continuous shooting rate: 11fps | Maximum video resolution: 4K

Very capable autofocusing system
Excellent electronic viewfinder
Screen not touch-sensitive
Tilting rather than vari-angle screen

You don't have to go full-frame to get the benefit of Sony's great camera technology and this APS-C format model makes a great choice for enthusiasts looking for an alternative to big, heavy SLR. One of the challenges for CSC manufacturers has been to make their autofocus systems as good as the ones in SLRs. The A6300's comes very close, especially in bright light; it's able to track moving subjects around the frame and as they move towards or away from the camera. There's also an excellent electronic viewfinder that makes it easy to see when the subject is sharp and correctly exposed. Image quality is very high and there's built-in Wi-Fi and NFC connectivity to allow to share images via a connected smartphone.

Pen

6. Olympus Pen-F

Sleek retro styling partnered with a host of creative features

Sensor size: Micro Four Thirds | Resolution: 20MP | Viewfinder: EVF | Monitor: 3-inch, 1,037,000m dots | Maximum continuous shooting rate: 10fps | Maximum video resolution: 1080p

High-quality electronic viewfinder
Build quality and controls
Expensive
Small buttons

While the design follows that of the original film Pen-F camera from the 1960s, that's pretty much where any similarities stop, with this modern-day Pen-F featuring Olympus's latest 20MP Micro Four Thirds sensor. Unlike previous Pen models we've seen which rely solely on the rear screen for composition unless you want to invest in an optional attachable electronic viewfinder, the Pen-F incorporates a high-quality OLED EVF integrated into the body with with a resolution of 2.36m dots. There's also an advanced 5-axis image stabilisation system built in to combat camera shake, while no Olympus CSC could be complete without a selection of Art Filters - the Pen-F has 28 to choose from. Offering plenty of customisation and a host of clever features, there's also built-in Wi-Fi connectivity to boot.

FujiXT1

7. Fuji X-T1

Classic handling, beautiful images – the X-T1 doesn't put a foot wrong

Sensor size: APS-C | Resolution: 16.3MP | Viewfinder: EVF | Monitor: 3-inch tilting display, 1,040,000 dots | Maximum continuous shooting rate: 8fps | Maximum video resolution: 1080p

Classic controls
Rugged build
Advanced filters JPEG only
Expensive compared to X-T10

Not so long back the X-T1 was our favourite compact system camera, but things change quickly in the world of cameras, and it's been pushed out of the top spot. Price has proved the X-T1's main enemy – it's a great camera, but it's held its price almost too well, so that the newer Fuji X-T10 is almost as great and much cheaper. The Olympus E-M10 II has come along too, with its brilliant blend of size, features and value, and competitive pricing means the Sony A7 II is now very good value for those who value performance above all else. The X-T1's external manual controls for shutter speed, lens aperture and ISO setting are still a joy to use and we love the results from its X-Trans sensor, but its rivals are getting ever stronger. That's not forgetting the recently announced X-T2.

GX80

8. Panasonic GX80/GX85

A stripped-down GX8, but its all the better for it

Sensor size: Micro Four Thirds | Resolution: 16MP | Viewfinder: EVF | Monitor: 3-inch tilting screen, 1,040,000 dots | Maximum continuous shooting rate: 8fps | Maximum video resolution: 4K

Great features for the price
Consistent AF performance
Ergonomics could be better
Doesn't use the latest 20MP sensor

With the GX80 (known at the GX85 in the US), Panasonic's taken the well-liked GX8 and streamlined some of the features to end-up with an appealing alternative that's more competitively priced. Despite sacrificing the clever tilting EVF, resolution is actually improved on the fixed EVF on the GX80, and while it also forgoes the 20.3MP Micro Four Thirds sensor and replaced by the older 16MP chip, the AA filter has been removed for sharper images. The GX80 also comes with 4K video capture, with the ability to capture 8MP stills from recorded footage - it's like a ultra-fast 30fps burst mode). Handling could be a bit more polished, but AF is fast and accurate, compact body and lens combination, very effective in-body anti-shake control and 4K video make this a very well-rounded camera.

Sony A7

9. Sony A7

A more affordable way to go full-frame with a mirrorless system camera

Sensor size: Full-frame (35.9x24mm) Resolution: 24.3Mp Viewfinder: EVF Monitor: 3-inch TFT LCD with 921,600 dots Maximum continuous shooting rate: 5fps Maximum video resolution: Full HD

High quality images
Full-frame sensor, affordable price
Needs a faster AF point setting
You'll need a second battery

With 24 million pixels the A7 may not be able to able to capture quite the same amount of detail as its high resolution sibling, the A7R II, but as it has the same sized sensor you get the same level of control over depth of field. That means you can make your sharp subject stand out from a blurred background. As it's from the first generation of Sony's full-frame compact system cameras it lacks the handling refinements and stabilisation that come with the second. But you get a lot of camera for your money, so it's too much of a bargain to exclude from this list. And rest assured, the image quality is excellent.

Panasonic GH4

10. Panasonic GH4

Is it a stills camera or a 4K video camera? The GH4 is brilliant but conflicted

Sensor size: Micro Four Thirds | Resolution: 16.1MP | Viewfinder: EVF | Monitor: 3-inch tilting screen, 1,036,000 dots | Maximum continuous shooting rate: 12fps | Maximum video resolution: 4K

4K video and 14fps continuous shooting
Metal chassis
Some fiddly and complex controls
Starting to show its age

The GH4 was a terrific, ground-breaking camera and its 4K video capabilities became legendary amongst professional film-makers. It's also a very good stills camera capable of shooting top-quality 16MP images at up to 12 frames per second. You can even extract really good 8MP stills from 4K video shot at 30fps. But all this processing power has made the GH4 expensive, so unless shooting high-speed action stills and video is your speciality, you could be paying for power you won't use. It's a firm favourite amongst 4K film-makers and early adopters, however, and while prices have fallen since its launch in 2014, its reputation just seems to keep on growing. It's been standing still just a little too long, though, and 4K video capability is becoming relatively commonplace.
