Mirrorless Camera Comparison Guide 2012

Image Gallery (40 images)

Mirrorless camera systems finally feel like they have come of age. Yes they've been knocking around for a couple of years, but over the last 12 months we've seen models which can genuinely rival DSLRs in terms of image quality and performance. While this choice is great for the camera-buying public, it also makes it even more tricky when deciding which system to invest in ... which is why we decided to compile a guide to the top mirrorless camera releases of 2012.

There have been simply too many mirrorless cameras released this year for us to look at them all. So we narrowed our comparison down to the six which we consider to be the most notable:

  • Olympus OMD EM-5
  • Sony NEX-6
  • Fuji X-Pro1
  • Panasonic LUMIX GF5
  • Nikon 1 V2
  • Canon EOS M

Cameras which almost made it into our comparison, but were just edged out by those above, include the Fuji X-E1, the Panasonic LUMIX DMC-GH3, the Olympus PEN E-PL5 and the Samsung NX1000.

Size and Weight

Mirrorless cameras come in all shapes and sizes – just look at the Pentax K-01 – and there's quite a range, even within our pick of the six best from 2012.

The Fuji X-Pro1 and the Olympus OMD EM-5 are considerably bigger and heavier than most mirrorless options, mostly due to their viewfinders and beefy construction (more on that later), while the Panasonic GF5 and the Canon EOS M are battling it out for that spot in your jacket pocket with the smallest dimensions.

Sensor Size and Megapixel Count

More pixels mean a camera can produce more detailed images, but if they're crammed on a small sensor, the resulting images can be noisy. So getting the right balance between sensor size and megapixel count is important.

The Panasonic LUMIX GF5 has the smallest pixel-count of the bunch with 12 MP, but it uses a 4/3" sensor... which means its pixels are still bigger than those in the Nikon 1 V2 with its 14.2 MP and smaller 1-inch-type sensor.

Most of the mirrorless cameras here with APS-C sized sensors share a pixel-count around the 16 MP mark, while the Canon EOS M has the highest at 18.0 megapixels.


The Nikon 1 V2 features the most Autofocus points with 73 phase detection areas and 135 contract detect areas – helping it achieve ultra-fast focus which, it's claimed, rivals some professional DSLRs.

The Sony NEX-6 also combines phase-detection and contrast-detection to achieve speedy focus in most lighting situations, with a respective 99 and 25 AF points. At the other end of the scale the Panasonic LUMIX GF5 has just 23 AF areas.

FPS Burst Rate

Because mirrorless cameras don't require a mirror to flick up and down between taking images (like DSLRs) they're often capable of faster burst rates. That's certainly the case with the Nikon 1 V2, which can shoot 15 frames per second with autofocus, or a blistering 60 fps with focus position for the first frame fixed.

The Sony NEX-6 and Olympus OMD EM-5 aren't far behind with 10 fps and 9 fps respectively, but the Canon EOS M appears somewhat sluggish with just 4 fps, though this could be that with 18MP it is handling more data… or just because Canon doesn't want to canabalise DSLR sales.

ISO Range

While a large ISO range should theoretically mean good quality images in any lighting conditions, this category has to be taken with a pinch of salt. Not all ISO 1600 settings are created equal, while one could produce clean images, another could leave you with messy noisy shots.

Also, while most of these cameras have an ISO which is expandable to 25,600, you have to question when you would ever use this setting given the blotchy mess your resulting images would be.

Viewfinder and/or LCD

Only the Fuji X-Pro1 boasts a hybrid optical/electrical viewfinder which overlays electronic data over an optical viewfinder, while the Sony NEX-6 has the highest resolution EVF with 2,359k dots. This is followed by the the OMD and Nikon 1 V2 with 1,440K dot EVFs.

All of the cameras feature three inch monitors on the rear, but with 1,230K dots the one of the Fuji X-Pro1 has the highest resolution, though not far behind is the Canon EOS M with 1,040K dots and the added benefit of touchscreen abilities.

Though the Olympus OMD EM-5 features the lowest resolution with a rather dated feeling 610K dots, its tilting OLED screen can come in handy when shooting in awkward positions.

Storage Media and File Types

SD/SDHC/SDXC compatibility reigns supreme as the storage media of choice for mirrorless cameras, but the Sony NEX-6 adds the ability to use Memory Stick PRO Duo if you've still got any of those proprietary memory cards lying around.

All of the cameras in our comparison offer the ability to shoot RAW or JPEG images, but while 12 bit RAW is the most common, the Canon EOS M allows 14 bit RAW files, which some would argue gives you more options when editing files.

Construction and Weather Sealing

The most notable construction details amongst the mirrorless cameras are the die-cast aluminum alloy top and base of the Fuji X-Pro1 and the magnesium alloy body of the Olympus OMD EM-5, which gives both cameras a sturdy feeling, but with the obvious additional heft.

The Olympus OMD EM-5 is the only one of the cameras to be weather sealed in the same way as professional DSLRs, meaning that if you plan on shooting in extreme weather conditions, it's probably the obvious choice.

Video Modes

Full HD recording is offered across the board, but with a few caveats: The Sony NEX-6 is the only camera to feature 50p recording at 1080, the others peak at 30p, or in the case of the Fuji X-Pro1, 24p which gives a more movie-like appearance. By the time you reduce to 720 HD, 60p recording has become the standard.

Wired Connections

There's USB 2.0 and HDMI output on all of the cameras, via either micro or mini connectors. However, only the Nikon 1 V2 and Canon EOS M have a 3.5mm audio input for using an external microphone while recording video.

Wi-Fi Options

While the Olympus OMD EM-5 can have wireless capabilities with the use of an optional Bluetooth dongle, the Sony NEX-6 is really the stand-out performer when it comes to wireless prowess.

PlayMemories Camera Apps, which can be downloaded to the Sony NEX-6 via built-in Wi-Fi, allow for features like the direct uploading of files to the internet, and the ability to control the camera from a smartphone or tablet.

Kit Lens

Kit lenses can be a great starting point with a new camera. They offer great value, opposed to buying lenses separately, though there's little point buying a interchangeable-lens camera if you're only ever going to use one lens.

Most of the kit lenses are wide to medium focal-range zooms with average aperture ranges. However the 22mm f/2 prime, which is bundled with the Canon EOS M, is considerably faster (allowing for lower light photography and a shallower depth of field) and stands out as a lens which will still get used, even if you acquire a selection of glass.

Lens Mount

The Olympus OMD EM-5 and the Panasonic LUMIX GF5 share a Micro Four Thirds lens mount, meaning a wide range of compatible lenses, while the other cameras each use mounts designed specifically for their manufacturer's range or mirrorless cameras.

While the number of lenses available for some of these mounts is somewhat limited, it's worth remembering that adapters can give you an arsenal of lenses at your disposal on all of these cameras, though sometimes without metering or auto-focus.

The likes of the Nikon 1 V2 and Canon EOS M have adapters available allowing the use of their respective DSLR lenses... and Leica lenses look awfully nice on the front of the Fuji X-Pro1.


A quick look at the prices of the cameras in this comparison shows they are not all competing for the same market. The Panasonic LUMIX GF5 is the least expensive at US$500 with a kit lens while the Fuji X-Pro1 comes in at $1,400 for the body only.

Obviously, you could buy a DSLR for the same price as many of these mirrorless cameras, which at one point would have been an obvious choice, but these mirrorless cameras are able to produce images which are just as good, and often in a smaller and more portable form.

Summing Up...

There's never been a better time to be in the market for a mirrorless camera system, any of the cameras in this comparison are more than capable of shooting stunning images… and you have to wonder how much longer DSLRs have got outside of the professional market.

It's really just a matter of deciding what size, price and functions are important to you and, as is always the way with cameras, the best way to know which one is right for you is to feel them in your own hands. You might decide you couldn't be happy without a separate viewfinder, or that you want the smallest mirrorless camera you can, to make it more likely that you'll carry it around with you everywhere you go.

If I was currently in the market for a mirrorless camera, the Fuji X-Pro1 would be the one at the top of my shopping list. The sturdy construction, retro looks and manual dials all appeal, but the optical/electrical viewfinder really makes it stand out from the competition. Coming from using film cameras and DSLRs I struggle to enjoy the experience of using an LCD screen to compose shots, and even the best EVFs can suffer a slight lag. Also, while sluggish autofocus was once a reason to steer clear of the Fuji X-Pro1, a recent firmware update has made it positively zippy.

Why not include the Sony Nex 7?

Robert Mo

Frankly I'm amazed how long it took to give us cameras without a mirror. In the digital age it was redundant from day 1. I assume the camera makers did not think us consumers would pay for a high end non mirror DSLR. Finally digital cameras have come of age. Thank you Gizmag for comparing the latest offerings.


No gh3? How dare you.....

The Sony NEX 6 has a fantastic 2.3 million dot EVF which has a very high refresh rate. It also has auto switching from viewfinder to LCD. It also has a very compact 16-50mm kit lens with power zoom. That lens on that camera allows me to carry the camera in either a vest or jacket pocket, a very big plus since it means I always have a camera with me



I just got a FujiFilm X-Pro-1, I have been waiting for sometime for a camera like this and Im very happy with it. With an adapter it takes many of the lenses I have left over from my film cameras, even if there not digital lenses I still get great results and with a little savie photoshop work you would not know. 14,000 for an M9 leica is a little to much and from what I have used the image quality is not all its cracked up to be.

Allan Johnston

Great review.

Unfortunately each camera has at least one significant shortcoming when compared to its peers.

Hopefully by mid or end 2013 we will see cameras from all these makers that are equally excellent in all the areas mentioned, then we will be dumb struck with buyers choice paralysis. I can't wait!

Russell Vonthien

I was glad to see you updated the review to include the EVF on the NEX 6. It is a shame you did not delve deeper into using the cameras, since if you had your opinions would be much more valuable. Things like accidently changing exposure comp or hitting the movie button or doing anyone of a number of dumb things are important to report on.

My main problem with the NEX 6 is how often I accidently change exposure compensation. I carry the camera in a vest jacket pocket so it I can accidently change things. It just takes some geting use to check things out a bit more carefully before shooting if you like carrying a camera in a pocket rather than hanging it around a neck.


I'm surprised the flagship camera from Panasonic was left out. The GH3. To add insult you mentioned it was edge out by the list of cameras which included Panasonic LUMIX GF5. This model is an entry level version in comparison.

Scott Triffett

Many thanks Simon for this round up of mirrorless camera options.

James Wood

Thanks Simon for the fabulous review. Really helpful comparison is done. I'm trying to buy digital cameras. Now it's really easier me to decide which camera to buy. :)


Wait, Sony's adaptor is really cool! they add a Translucent mirror and an image stabilizing unit to the NEX series that can use A mount lenses and compatible Minolta lenses. (NEX sports Sony's 16.1 MP APS-C sensor).

Also, I find the EOS M late to the game and drastically slower with it's non-expansive lens line up. One of the most feeble attempts on the market as far as I can figure. Nice touch screen Q menu though!

An example of the Canon EOS M's drastic price drops: http://camelcamelcamel.com/Canon-Compact-Systems-3-0-Inch-EF-M18-55mm/product/B00A2BVCO0?context=browse
