Performance
Verdict
Specification



All of these cameras fit into the mirrorless compact system camera category and feature Digital SLR sized sensors, but by removing the mirror from the camera, they offer much more compact sizes, and also new lens mounts to match the sensor.

Panasonic and Olympus both use Micro Four Thirds sensors (size 17.3 x 13mm - the same size as used in Four Thirds DSLRs) and Micro Four Thirds lens mounts, meaning you have a choice of Olympus and Panasonic lenses. Samsung and Sony use APS-C sized sensors (size 23.4x15.6mm - the same size as most DSLRs), and Samsung use the NX lens mount with 9 lenses available, and Sony use the E-Mount with 4 lenses available.

Panasonic Lumix GF3	Sony NEX-5

Features

Apart from the visual differences between the models, with the Samsung NX11 featuring a DSLR style body and built in electronic viewfinder, these cameras all feature large sensors, and interchangeable lenses. Olympus and Panasonic share the Micro Four Thirds lens mount, meaning you can swap lenses between the cameras, whereas Samsung use the NX mount, and Sony use the E-Mount.

The sensor is exposed when you remove the lens, and you need to be careful not to get any dirt near the sensor:

The GF3 is the smallest with built in flash, the Sony NEX-5 is the smallest if you ignore the lens, and the NX11 the most Digital SLR like in design. The Olympus PEN E-P3 is the next biggest, out of the cameras, after the NX11.

Handling

All four cameras feature metal bodies apart from the NX11. However, the Olympus PEN E-P3 feels the most solid with a stylish chrome plate on the top of the camera, it also gives you a choice of grips, from no grip, the small grip shown, or a larger more SLR styled grip. The GF3 has the thinnest strap loops, with the E-P3 featuring the most solid looking - although they do require additional metal loops. The GF3 doesn't feature a rubber grip at the front, instead opting for a large raised metal grip.

The Sony NEX-5 features a large rubberised grip, and the minimal buttons fall neatly under your fingers and thumb, although the lack of buttons also caused some issues as it meant setting some options relied on entering the menu system.

Shutter sound: The quietest is the NX11, followed by the EP3, and the GF3, then the NEX-5 is the loudest.

Panasonic Lumix GF3	Sony NEX-5

The PEN and NX11 give numerous external controls, buttons, wheels, mode dials and quick access to numerous settings, whereas the NEX-5 and GF3, with their ultra compact bodies, feature an almost minimalistic approach to button layout. The Sony relies on a scroll wheel and two "soft" buttons - this means the use changes depending where you are in the camera's menus, for example to enter the menus you press the top button, but once in there it acts as a back button. The GF3 instead uses a touch screen so that you can still set a lot of the options through the "Quick menu".

Menus: The Sony NEX menus seem the most strangely arranged - the menu system seems unlike any other Sony camera, with the Sony Cybershot range giving quick access to photo options on the preview / live screen, and Sony's Alpha DSLR range giving familiar DSLR styled menus.

Olympus menus are well laid out, but to access the full controls, you have to switch on the "Advanced menus" then it becomes daunting having page after page of options. The Samsung NX11 has clearly laid out menus, but colour coding would help further distinguish the menus.

Panasonic's menus are well laid out and clear to read and easy to use. Both the GF3 and NEX-5 have a virtual mode dial. Press the middle button on both, and then the scroll wheel becomes the mode dial, letting you scroll through the modes.

Battery Life - CIPA rating vs actual battery life in use:

Sony NEX-5	PEN E-P3	Panasonic GF3	Samsung NX11
330 (CIPA)	330 (CIPA)	340 (CIPA, 14mm lens)	400 (CIPA)
330	320	310	400+

The battery life of the Samsung NX11 impressed us the most, with it providing the most shots, although this was expected as it has the largest capacity of the batteries. The GF3 was lower than the CIPA rating, and along with the PEN, and NEX-5, they all gave around 310-330 shots. Although the use of different lenses, shooting modes, and the amount of times you switch the camera off and on may alter your battery life.

Speed - we tested the four camera's performance at focusing, shutter response, and shot to shot time with and without flash, and continuous shooting using JPEG, RAW and Flash when available. You can also compare the results to the new Panasonic Lumix G3 as well.

* 14-42mm Olympus M Zuiko 14-42mm II R lens used for both m43rds cameras, tested with the new Samsung Class 10 memory card.

The Sony NEX-5 clearly has the quickest continuous shooting mode at 7fps, with the GF3 shooting at 4fps, and the EP-3 and NX11 both shooting at 3fps. The GF3 doesn't offer the option to shoot with flash when using the continuous shooting mode, and the EP3 shoots quite slowly with 1.6 seconds between shots with flash on. The NX11, and NEX-5 both shoot at 2fps with flash. Shot to shot time is good with all cameras performing well, although the E-P3 slows to a shot ever 2 seconds with flash on.

The switch on time of all cameras is good, with the NX11 the slowest, although at 1.3 seconds from off to on and taking a photo, it's not exactly slow compared to many other cameras. The Olympus PEN E-P3 is the quickest at switching on and taking a photo, managing this in just 0.7 seconds.

The focus and shutter response speeds of all cameras is good, with the slowest focusing in 0.4 seconds - this is similar to a decent compact camera, with the quicker models shooting at around 0.3 seconds. The Samsung NX11 focuses quickly at 0.3 seconds. However, the Panasonic and Olympus cameras both focus very quickly at 0.2 seconds to focus and take a photo - this is extremely quick and we wish all cameras were this quick.

Lens Test Images: The wide shots show purple fringing in the trees, and how the camera deals with detail in both highlight areas, as well as in shadows. The EP3 has the edge over the GF3 with slightly more detail in the shadow areas. The NX11 has the most detail of the four cameras, and also the lowest purple fringing or chromatic aberration - with the EP3 and GF3 both showing purple fringing in the trees. The NEX-5 shows red and blue chromatic aberrations, as well as low detail towards the sides of the frame. The telephoto shots show good detail from the GF3 and EP3, when using the same lens, the NX11 shows excellent detail, and is sharp right across the frame, and the NEX-5 shows the least detail, with chromatic aberrations, and soft detail along the sides of the frame.

Vignetting was not noticed on the lenses. Some barrel and pincushion distortion was noticed with the Samsung NX11 and Sony NEX-5, although this didn't cause issues in real world shots, but can be seen in the ISO test shots.

The Panasonic Lumix GF3 with the 14mm f/2.5 kit lens is at a disadvantage as it lacks the ability to zoom compared to the others (so we have used the Olympus kit lens for these zoom shots), and it also is at a disadvantage for macro shots compared to the other lenses that allow macro shots to be taken at full telephoto zoom.

Samsung and Sony allow both vertical and horizontal panoramic shots. The Panasonic is missing panoramic modes, and although the Olympus does have the feature built in, this is just to aid you for stitching them together later on the computer.

Scene modes: The Olympus features High Key / Low Key scene modes (while other cameras call them "creative filters" or "art modes" when Olympus DSLRs and PEN cameras have had these scene modes or gradation options for years). The Sony features a "Handheld Twilight" mode that will take a number of shots and combine them for a noise free image. Samsung Backlighting mode (switches on flash).

Noise: ISO3200 from the Samsung shows similar levels of noise as the Olympus PEN E-P3* and the Panasonic Lumix GF3, although the GF3 has stronger noise reduction applied, and shows more image artefacts. The Sony NEX-5 shows the lowest noise levels at this high ISO setting.

* The E-P3 was set to low noise reduction, the standard noise reduction option reduces noise more, but also reduces detail. The E-P3 provides usable ISO6400 with ISO12800 best avoided.

Samsung doesn't give the option to go above ISO3200. The NEX-5 gives very usable ISO6400, with ISO12800 possibly being useful if resized.

The Sony provides the lowest noise details, followed by the E-P3, which is very closely matched / followed by the GF3, with the Samsung NX11 producing the least options and strangely the most noise filled images although this would explain the high levels of detail.

Sample photos image quality: The landscape shot gave the cameras a challenge, with a bright sky and dark foreground. Most of the cameras performed well without overexposing the bright sky, apart from the Panasonic Lumix GF3, which has blown highlights in the sky. All of the cameras manage to produce pleasing bokeh when using the full zoom of the telephoto lenses (The GF3 shot was taken with the Olympus 14-42mm MK2 lens), although the NX11 and NEX-5 with larger sensors produce more out of focus area. The Olympus gives the warmest results, even with "Warm AWB" switched off, and appears to enhance browns, and the Samsung and Panasonic cameras give the coolest results. Portrait shot - the cameras all produced flash shots without red-eye however, the exposure and colour produced varied quite noticeably on each camera. The NX11 slightly underexposed the shot and shows more noise even at ISO400. The Olympus again gave the warmest results, the Panasonic quite cool results, and the Sony gave a slightly warm version, but the most pleasing image overall.

All of the models give some option to increase dynamic range, the Olympus E-P3 option is called shadow adjustment, the Panasonic Lumix GF3 has 3 levels of iContrast, the Samsung NX11's version is called Smart Range and the Sony NEX-5 has the most advanced with D-Range Optimiser and true HDR that takes 3 shots and combines them.

The EP3 gives sharper JPEG output than the GF3  - probably as much sharpness / detail as you can get from the 12 megapixel sensor. The NX11 has excellent detail throughout the frame and excellent sharpness when used as ISO100. The Sony NEX-5 gives the softest results, with noticeable softness towards the sides of the image.

Video Quality
Full HD is beginning to be an expected feature on Digital SLRs and Mirrorless cameras and unsurprisingly these cameras all feature Full HD, excluding the Samsung NX11, with just 720p video. The Olympus PEN E-P3 features full manual controls.

Value

The Samsung NX11 offers the best value for money out of the four mirrorless cameras tested here, priced at £389 with 18-55mm kits lens, although there are other mirrorless cameras available that are cheaper, such as the Samsung NX100, Panasonic Lumix GF2, and the original Olympus E-PL1. Next the Sony NEX-5 with 16mm lens is priced at £430 offering good value for money. The Panasonic Lumix GF3 is around £449 with 14mm kit lens also offering good value for money. The Olympus PEN E-P3 is the most expensive at £799 with 14-42mm kit lens, this gives it a higher price than the Panasonic Lumix GH2, and even some Digital SLRs, such as the Nikon D5100 and Canon EOS 600D. Other alternatives worth looking at include the Panasonic Lumix G3 (with built in viewfinder) and the Olympus PEN E-PL2.

Verdict

The Olympus PEN E-P3 with extremely fast auto focus and impressive 3 inch touch screen is a great camera to use and provides a massive wealth of options and creative features. The art filters are boosted by the addition of effects that can be applied to the filters. The build quality is by far the best, with a reassuringly solid build, and the ability to remove and change the grip is such a brilliant idea, it makes us wonder why nobody thought of it before. The image quality is excellent and the camera will either give you smooth noise free images left on default settings, or alternatively turn the filter down to low, and you have excellent detail, and slight grain (this was my preference). Built in anti-shake is another excellent feature, especially if you plan on using other lenses. The Olympus PEN 14-42mm collapsible kit lens is clever, helping keep the camera pocket-able, without limiting you to a fixed focus pancake lens. The price however makes it the most expensive option here, and I wonder whether the soon to be available EPL3 (at £550 with faster continuous shooting) will give purchasers of the EP3 second thoughts.

The Panasonic Lumix GF3 is the smallest with built in flash, and has similar image quality to the EP3, although the EP3 seems able to draw out slightly more detail in images, and the 14mm kit lens (with slightly soft corners) gives the GF3 a disadvantage, one that it makes up for in size. The GF3 lacks the flash hot shoe of the GF2, and in some ways seems like a point and shoot version of a micro four thirds camera. It's also had some features cut from it, most likely in order to minimise the cameras size, and lacks an orientation sensor, and stereo microphones. An excellent camera with a few drawbacks, particularly compared to it's predecessor the GF2. Although if size and the micro four thirds format is of paramount importance to you then the GF3 makes a great choice.

The Samsung NX11 has the most SLR like body with a built in electronic viewfinder, rubber grips front and back, and numerous controls on the camera's body. Image quality at the lower ISO settings is excellent with great colour and excellent detail straight from the camera. Unfortunately at higher ISO settings, even at just ISO800 there is noticeable noise, and sticking to the lowest ISO settings will give the best results. The NX11 is also the best value for money, undercutting the other cameras, and providing an 18-55mm kit lens with optical image stabilisation. The NX series has a number of lenses available (9 at last count), with more expected, although the lack of third party adapters is disappointing. The panoramic shooting and 30fps (at reduced size) continuous shooting are neat features to have though.

The Sony NEX-5 has the smallest body of all the cameras here, thanks to using an external flash, however, it also has the largest lenses of all the mirrorless cameras, with the 18-55mm kit lens making the camera noticeably larger than the pocket friendly alternatives. The NEX series also features the smallest number of lenses - with just 3 currently available in shops, which is ironic considering there are also 3 camera bodies available in shops. Sony has announced a 30mm Macro lens and three more lenses are expected to be announced this year, and hopefully they will be in shops soon! The NEX-5 produces the most DSLR like images, with low noise right up to ISO3200/6400, although images are slightly soft straight from the camera. The price is reasonable at £430 with 16mm lens, or £490 with the 18-55mm lens, although the menu system of the camera made the camera awkward to use at times.

All of these cameras offer Digital SLR-like image quality and the NX11 offers Digital SLR-like handling. However, the cameras all offer much more compact bodies than an equivalent DSLR and the speed in use, focusing in particular, is especially quick. The Micro Four Thirds cameras offer the most lenses, and the support by third parties in the form of adapters makes them an easy choice for anyone with DSLR lenses from any other camera. Unfortunately the NEX-5 and NX11 are supported much less by third parties, with adapters more difficult to find, and lenses particularly short on the NEX mount (currently) with the larger lenses not making the most of the compact body.

Each camera has strengths, and each camera has weaknesses. The NX11 suffers from noise, the E-P3 from the price, the NEX-5 from the lenses (or lack thereof) and confusing menus, and the GF3 from the size restricting its functionality. Which one you choose, therefore will be very much down to your personal preferences and needs, and hopefully this review will help you decide which camera is for you.

The most complete camera, offering both functionality, compact size, image quality, good handling with an abundance of features, and with the fewest number of weaknesses is...

The Olympus PEN E-P3 wins the Editor's Choice award as the most complete mirrorless camera available.

The Olympus PEN E-P3, with ultra fast focusing, the quickest switch on time, a great high resolution touch screen, excellent image quality, built in anti-shake that will work with ANY lens, (isn't this the whole point in having an interchangeable lens camera?) and interchangeable grips, is an obvious choice, as the best PEN series camera yet. In fact, it's one of the best mirrorless cameras this year! Therefore it is to be Highly Recommended, and is our Editor's Choice.
