Lets meet today in photo area with compact mirror-less photo-camera Olympus PEN E-PM1 with Micro Four Thirds mount for interchangeable lenses. 4/3″ MOS sensor with 12.3 MP effective resolution is built into it, image stabilization is performed via this sensor shifting, image is processed by TruePic VI graphical processor. Camera makes photos with 4032 x 3024 pixels maximal resolution and saves them in JPEG, RAW ( with 12 bits per channel precision and lossless compression ), RAW + JPEG and MPO; it records video in Full HD 1920 x 1080 60i, HD 1280 x 720 60i and VGA 640 x 480 30 modes, saving it in AVCHD and AVI Motion JPEG formats with Dolby Digital and stereo РСМ 16 bits and 48 kHz sound formats, accordingly. Microphone records stereo sound and there is ability to attach external one via special Olympus SEMA-1 adapter ( however in this case it is better to buy separate sound recording device with higher-quality microphones and lossless audio formats ). ISO sensitivity levels are in 200 – 12800 range, color space is only sRGB. There is ability to attach external flash to camera ( it is bundled in package ), it has no built-in internal one, has no built-in viewfinder and has 3″ LCD screen with 460 K dots resolution.

Olympus PEN E-PM1 supports automatic and manual focus, exposition and diaphragm settings, it can be used for astronomical photos making. It saves photos and videos on SD, SDHC and SDXC ( UHS-I ) flash memory cards; has no Wi-Fi connections support for remote data transfers and control, but has Eye-Fi and Bluetooth connections for this purpose. From connectors there are USB 2.0 for data transferring and Li-ion battery charging, HDMI Micro Type D, AV output, Hot Shoe and Accessory Port 2; 1 charge of its battery is enough for 330 photos making.

Camera sizes are 109.5 ( width ) x 63.7 ( height ) x 34 ( depth ) mm and mass is 265 g ( without lens and with memory card and battery ); its body is made from metal. It can work in 0 – 40 degrees on Celsius temperatures range and relative air humidity levels 30 – 90 %. Package contains : Olympus PEN E-PM1 camera itself, external flash, USB cable, audio-video cable, Li-ion battery, recharger, optical disk with software ( Olympus Viewer 2 ), shoulder strap, warranty card and user’s guide; there are also kits with bundled lenses. Camera gives great photos and videos, lenses are interchangeable and it records stereo sound ( basing on my experience of use of other Olympus camera, I can say, that sound is good with basses, which are not present in sound of many large mirrored cameras, and with good stereo channels separation; the most likely, this model has similar microphones ). Its minuses are : small amount of specialized controls, very small sizes, lack of protruding parts for hands grip and high slipperiness of surface, but this is mainly a consequence of its compact sizes.

This is a great compact mirror-less photo-camera with very good photos quality and good video quality and large amount of specialized controls. Its weak side is only sometimes wrong light temperature determination under artificial lighting; this can be solved by its manual setting in such situations.

Lets meet today with compact mirror-less camera Panasonic Lumix DMC-GF2 with Live MOS sensor Micro Four Thirds ( with 12.1 MP effective resolution ) and the same mount for interchangeable lenses. It can save photos in JPEG ( in this format it has higher amount of compression artifacts, than competitors have ) and RAW formats; it can record videos in Full HD 1920 × 1080 60i/50i and HD 1280 x 720 60p/50p modes and save them in AVCHD format with MPEG-4/H.264 image encoding and stereo sound recording. Image is processed by Venus Engine FHD; camera supports optical image stabilization with lenses, which can perform it. Its ISO sensitivity levels range is 100 – 6400; during videos recording camera does not let to control optical parameters manually and controls them in automatic mode. It has built-in flash, has no viewfinder and its 3″ touch LCD screen has 460 K dots resolution.

During photos making camera lets to control focus, diaphragm and exposure automatically and manually and it can be used for astronomical photos making. It saves photo and video on SD, SDHC and SDXC flash memory cards; and does not support Wi-Fi connections for remote data transfers and control of camera. It has following connectors : USB 2.0 for data transfers and Li-ion battery charging, HDMI C Mini, AV output and Hot Shoe interface. One charge of its Li-ion battery is enough for 300 photos making; its sizes are 113 ( width ) x 68 ( height ) x 33 ( depth ) mm and mass is 265 g ( only camera body without lens, battery and memory card ).

All in all, this is a very good compact mirror-less camera with interchangeable lenses, its weak sides are relatively big amount of compression artifacts during JPEG photos saving and only automatic optical parameters control during videos recording; in all other aspects this camera is very good. So, when camera of such type is being chosen, there is need to look on its price and on the fact, whether its characteristics and weaknesses are acceptable.

Lets meet today with compact mirror-less photo-camera Sony Alpha NEX-3N with APS-C sensor with 16.1 MP effective resolution and Sony E mount for interchangeable lenses.

It is very functional compact mirror-less camera : it has APS-C sensor ( larger sensors are usually built into heavy mirror cameras ) and it can record Full HD video; so, if there are enough money for purchasing of this camera, then it is the best choice. But if APS-C sensors of Sony are too pricey ( this company never set low prices on its products, but usually have very good quality ), then there is ability to look on Olympus and Panasonic cameras of such type with Micro Four Thirds sensors.

Lets review compact mirror-less camera Olympus PEN E-PL3 with interchangeable lenses for Micro Four Thirds mount. It has High speed Live MOS Sensor with 4/3″ size and 12.3 MP effective resolution; it can make photos with 4032 x 3024 pixels maximal resolution ( with ISO 200 – 12800 sensitivity levels ) and save them in JPEG, RAW ( with 12 bits per channel precision and lossless compression ), RAW+JPEG and MPO formats in sRGB and Adobe RGB color spaces.

Camera has no built-in viewfinder and flash, they can be attached via Hot Shoe interface. Its tilting 3″ LCD display has 460 K dots resolution; sensor-shifting image stabilization is built into it.

Camera supports automatic and manual focusing, exposure control and diaphragm settings, it has remote control support via special cable; it can be used for astronomical photos making. It saves photos and video on SD, SDHC, SDXC ( UHS-I compatible ) and Eye-Fi flash memory cards and does not support Wi-Fi connections for data transmitting and remote control. Following connectors are built into it : USB 2.0 for data transferring and Li-ion battery charging, Mini HDMI type-C, VIDEO-OUT, Accessory Port ( AP2 ) and Hot Shoe.

There also are kits with bundled photo-lenses. This camera is one of the cheapest cameras with interchangeable lenses, wherein it has relatively big sensor ( of the same size as top-level Olympus cameras have ) and can record Full HD video; it has no mirrors, its body is made from metal and it has compact sizes and small mass, so, it is useful in travels and shooting from hands ( especially with optical image stabilization ). Weak side of camera is small amount of dedicated controls, but this is a consequence of its compact size and design for novice photographers. So, this camera can be surely recommended for purchase, when there is need in camera with big sensor and interchangeable lenses and there is no wish to pay for Sony NEX and Canon EOS M cameras with their APS-C sensors.
