The British Journal of Photography (BJP) has published a test report by Edmond Terakopian, award winning photojournalist of the Olympus E-P2 with several lenses. The report is in the current issue of BJP.
The lenses tested on assignment with the E-P2 body are: Leica 35mm Summicron, Olympus 17mm pancake, Olympus 14-42mm, Leica designed Panasonic 45mm F2.8 Macro at ISO500. The pictures look stunning at the sizes printed.
The E-P2 earned his high praise and his only real gripe was that RAW processing in some 3rd party converters struggle with both these and RAW files from the Panasonic G series due to the embedded lens correction data in the exif data.
He used Exif software "facefullof bees" to strip out this data so that he could use his favourite unspecifed converter. He did mention though that the JPEG's from this camera are also superb.
He particularly liked the EVF viewfinder attachment, anti-dust system and in camera stabilisation so that any lens fitted is also stabilised.
