Panasonic GF5 vs Olympus E-PM1: Sensor
Though not identical, these two cameras have a near match on their effective pixel count. The Panasonic Lumix GF5 has 12.1 million effective pixels, while the Olympus PEN Mini E-PM1 has slightly more, with 12.3million.
Panasonic GF5 vs Olympus E-PM1: Autofocus
Again, the pair run a level-pegging race this time in the autofocus arena, since both the Panasonic GF5 and the Olympus E-PM1 use a contrast AF system which both manufacturers claim to be the fastest in the world. The Olympus E-PM1 pulls ahead, however, dwarfing the Panasonic GF5's 23 focus points with 35.
Panasonic GF5 vs Olympus E-PM1: Video
Again both cameras mirror each other, with a Full HD movie quality of 1920 x 1080.
On both cameras, digital or 'Art' filters may be used while shooting, which adds more interest and creativity to the video.
Panasonic GF5 vs Olympus E-PM1: Flash
There are large differences between the Olympus E-PM1 and the Panasonic GF5 where the flash is concerned.
The Olympus E-PM1, for example, doesn't have a built-in flash, but it comes with a detachable flash unit that attaches via the hotshoe - which can also accept other, more powerful flashguns should the need arise.The bundled flash can even be used to control other flashes wirelessly.
This enables the camera to use different levels of flash compensation for a number of lighting conditions.
The Panasonic GF5 has no hotshoe, but it houses a built-in pop-up flash and seven flash modes. This means it is less versatile, but of course there's less hassle.
Panasonic GF5 vs Olympus E-PM1: Photo styles
The Olympus prides itself on the E-PM1's wide variety of shooting modes, including 24 different scene modes, some of which are the same as the Panasonic GF5's.
For example, the Olympus E-PM1 can offer users Macro, Sports, Night Scene, Children, Digital Image Stabilisation, Nature Macro, Candle, Sunset, Documents, Panorama, Fireworks, Fisheye Converter, 3D and more.
The Panasonic GF5 offers only one fewer, with a total of 23 shooting modes.
While the Panasonic GF5 has six creative filters: Dynamic Monochrome, Impressive Art, Cross Process, Soft Focus, Star Filter and One Point Colour, the Olympus E-PM1 has Pop Art, Soft Focus, Grainy Film, Pin Hole, Diorama and Dramatic Tone. The advantage with the Olympus camera is taht the user retains full control over the exposure when these Art Filter modes are used.
Panasonic GF5 vs Olympus E-PM1: Ergonomics and lenses
After jostling over creative ability, the Panasonic GF5 fights back with its choice of two standard kit optics (you can choose between a standard 14-42mm lens, or the newer, more expensive 14-42mm power zoom lens).
The Panasonic GF5 adds even more user interaction however, with its 3-inch touchscreen LCD monitor, which should make menu navigation and shooting adjustments quicker and simpler to use.
To add salt to the wound, the Panasonic GF5's LCD screen has a resolution of 920,000 dots, dwarfing the Olympus E-PM1's 460,000 dots.
In terms of its physical handling, the Panasonic GF5 has a total weight of 362g with its standard kit lens included, while the Olympus E-PM1 stands at a featherweight total of 265g.
Panasonic GF5 vs Olympus E-PM1: Verdict
Both compact system cameras are close competitors for most of the way, branching off in certain areas such as ergonomics.
Overall both cameras are pretty evenly matched, with the Panasonic GF5 perhaps pulling ahead with its longer video recording time and higher resolution interactive touchscreen for a more creative handling.
We like Olympus's Art Filters though.
