Olympus PEN Mini E-PM1 CSC Review: Olympus PEN Mini E-PM1

The Olympus PEN Mini E-PM1 is the smallest Olympus PEN released and introduces a whole new range of "Mini" PENs, assuming Olympus go on to release the E-PM2 and E-PM3 in coming years. To enable the smallest PEN yet, Olympus has developed a new smaller shutter system, shared with the Olympus PEN Lite E-PL3 and chopped off even more bits to make this camera teeny tiny.

The E-PM1, along with the E-PL3 share a new shutter system, high speed shooting at upto 5.5 fps, anti shake sensor, ultra fast focus, AF illuminator, Full HD video, stereo sound, completely new design, numerous colours and Art filters. The camera doesn't feature a built-in flash, instead a clip on / pop up flash is included. The kit lens is the same as the MK II, but the new R designation means that it has been redesigned cosmetically to match the updated PEN range. 

The Mini was announced along side the new E-PL3, and E-P3, which we have also reviewed. NB. Due to similarities between the E-PM1 and E-PL3, sections of this review are based on the E-PL3 review.

Olympus PEN Mini E-PM1 Handling

The Olympus PEN Mini E-PM1, with a name like "Mini" is the smallest Olympus PEN yet and is rather stylish and compact as you would expect. The compact camera lacks of any kind of front grip, and with a smooth finish it makes the camera feel quite slippery. Thankfully there is a rubber thumb grip on the back of the camera, and it's provided neck strap is definitely worth attaching to the camera for extra peace of mind. The memory / battery compartment is good and an improvement over the EPL1 / EPL2 with a locking mechanism much like the Panasonic Lumix G series of cameras.

The 16:9 aspect ratio of the screen means that a lot of it is wasted when taking and viewing 4:3 photos (the default aspect ratio). The customisable buttons: Record / Right (labelled flash) and Down (labelled Timer/Shooting mode) buttons can be set to various functions, however, the Record buttons can only be set to a limited set of functions (these are: AEL/AFL, Record, Preview, One touch WB, Home AF Position, MF, RAW, Test, Myset1, 2, 3, 4, Backlit LCD, Underwater, Live Guide, Digital Tele-Converter, Magnify, Off), then the Right / Down buttons can be set to ISO/WB/Lock scroll wheel, Exposure, Flash mode. Which I find a little awkward, personally, I would have liked to keep the flash and shooting mode / self-timer buttons where they are, and instead change the Record button to ISO. However, saying this, there is still an easy way to access all of these features by pressing the middle OK button, this brings up an overlay of controls on the screen.

Another minor gripe is that when you do press the OK button, and the options appear on screen (shown below right), they don't appear instantly, instead they "animate" / scroll onto the screen quite slowly, delaying you setting whatever it is you wanted to set. This wasn't the case on the E-P3 (firmware fix please, or add a menu option?) - when the camera is marketed as the World's Fasted Auto Focus it doesn't make sense to slow another area of the camera down with slow menus.

Mode selection Function controls

Menus: The menus are very similar to EP3, but with a different background colour and a simplified mode selection screen (shown above left). The PEN cameras have a refreshed menu system with easier to navigate controls, with a picture of the camera in the background. There is built in help and a built in camera manual. There is a live guide available in the iAUTO mode that lets you change saturation, colour warmth, brightness, blur the background, stop or blur motion, as well as access the built in guide. The more basic options are in the normal menus, then you can also switch on the Custom Menu and then there are literally hundreds of options! (70 options, each with sub options, over 10 colour coded screens)

Battery Life: Battery life is rated at 330 Shots (using 100% live view, under CIPA testing). We managed to take over 380 photos before the battery went flat, this is better than expected, although the number of shots achieved will depend on whether you shoot continuous, how often you switch the camera on / off and what features you use.

* 14-42mm Olympus M Zuiko 14-42mm II R lens used for both M43rds cameras, tested with the new Samsung Class 10 memory card.

As with the E-PL3 and E-P3, you can instantly tell that there have been massive improvements in the focusing speed, as focusing was very, very quick, and shutter response is practically instant. Continuous shooting is around 5 to 5.5 fps (with IS disabled) or 4 fps with IS enabled, which is excellent, and the fastest Micro Four Thirds camera yet, quicker even than the top of the range Panasonic Lumix GH2 (with 5fps shooting). After shooting 9 shots in continuous shooting mode at 5fps, the camera can then shoot at 2fps in JPEG mode.

Olympus PEN Mini E-PM1 Performance

Here are several sample photos taken in a variety of lighting conditions, click "Hi-Res" to view full size sample photos, there are more sample photos in the equipment database where you can also add your own photos:

Olympus PEN Mini E-PM1 Sample Photos

The photos shown here show excellent colour, detail, and the lens is capable of producing good background blur (bokeh) when used to focus on close subjects. The portrait shot with flash, shows very little red-eye, however the image is slightly underexposed.

Olympus PEN Mini E-PM1 Lens test images

The lens performs well with detail right to the corners, although there is some purple fringing in extreme contrast areas (the corners especially) although this was generally low in other photos. The kit lens is capable of decent macro performance when used at the telephoto end.

Olympus PEN Mini E-PM1 ISO test images

ISO Noise performance: (Noise Filter Standard, default: Standard). The E-PM1 produces low noise at ISO200, through to ISO800, even when the noise filter is set to low. At ISO1600 and ISO3200 coloured noise becomes apparent, and it's at this point that I'd want to switch the noise filter to standard. Similarly at ISO6400 noise becomes more noticeable and this setting would be best used with the noise filter set to standard. ISO12800 is best used resized, however, the camera does a good job at maintaining colour even at this high ISO setting.

The noise filter options are worth looking at if you want to increase sharpness, as the Low setting gives a nice grain with good detail, Standard (Default) does a very good job of removing most of the noise if you're not a fan of noise, whereas High seems as though the noise reduction is a little too strong, although your personal preferences may differ.

Olympus PEN Mini E-PM1 White-balance test images

Auto white balance: AWB performed well under tungsten and fluorescent lighting, often producing better results than using the respective presets. Interestingly the camera has an option to "Keep warm colour" when using auto white balance - this is useful for indoor situations where you want to capture the "mood" of the environment rather than have a technically correct colour rendition.

Olympus PEN Mini E-PM1 Digital filters

Art Filters - On the E-PM1, there are 6 Art Filters: Pin Hole, Pop Art, Diorama (Miniature), Dramatic Tone, Grainy Film and Soft Focus.

Lenses available: The E-PM1 comes with a collapsible zoom kit lens: the Olympus M. Zuiko 14-42mm II R - equivalent to 28 - 84mm, this is an updated version of the 14-42mm Mk II lens and is updated cosmetically only so that the style matches the new range of Olympus PEN cameras. As it's part of the Micro Four thirds system, there is an abundance of lenses to choose from, from both Olympus and Panasonic and others (such as Leica, Voigtlander, Samyang etc)! There is also a number of adapters available to allow you to use DSLR lenses, as well as a lot of third party "toy" lenses like the Pinhole PenWide, Holga, Toy Lens and others.

Video: Video on the E-PM1 is recorded as full HD video, with full manual controls (P, A, S, M, Art filters), although using the Art Filters greatly reduces the frame rate on videos. With Full HD, there is also further compression / size options including AVCHD Full HD Fine / Normal, HD Fine / Normal, MJPEG HD / SD, as well as a digital teleconverter that allows digital zoom.


Value for Money: Built in body stabilisation is a bonus of the PEN system, as it enables you to have image stabilisation with any lens, new or old, and is of particular interest if you're planning on using adapters to use third party lenses. The E-PM1 is currently priced at around £430 with kit lens, putting it in direct competition with the cheapest new models including the Sony NEX-C3 (around £399), and Panasonic Lumix GF3 (around £449).

Olympus PEN Mini E-PM1 Verdict

The Olympus PEN Mini E-PM1 features extremely fast focusing, which was originally one of the downsides of choosing the Olympus PEN camera over the Panasonic Lumix G cameras, however, now you can have you cake and eat it, with fast focusing, and built in image stabilisation. They've also produced a compact, stylish camera with fast continuous shooting at 5.5 fps. The AF illuminator and ultra compact size is also a welcome addition.

Olympus has expanded the appeal of the PEN series with new 12mm and 45mm lenses with an entirely metal construction, and a variety of lens converters are available. Image quality of the Olympus PEN Mini E-PM1 is excellent with excellent detail from the 12 megapixel sensor, with low noise and great colour. The PEN Mini E-PM1 is the most compact of the Olympus Micro Four Thirds cameras yet still gives you fairly quick access to controls through on screen functions, and three of the rear buttons can be customised.

Olympus PEN Mini E-PM1 CSC Review:
The Olympus PEN Mini E-PM1 is an ultra compact micro four thirds camera with image stabilisation, excellent image quality, and excellent value for money.

A point to remember if you do a lot of move shooting is that the Panasonics have a stereo mic with manual input level settings.

I shoot movies of bands I go to see and in my usual club the Olympus is unusable because the sound overloads. On the Panasonic I can turn the level down and get an incredibly good recording.

Some examples are at my youtube channel here

Olympus recordings under the same circumstances are so distorted by the sound levels as to be unlistenable.
