Image stabilisation	Lens dependant	Yes	No	No	Yes and extremely effective
Viewfinder	Excellent 100%	Novel hybrid, very good	No viewfinder	No viewfinder	Rubbish
Metering accuracy	About 0.3eV over	Spot on	About 0.3eV under	About 0.3eV over	About 0.3 eV over
Battery life	Fantastic	Rubbish	Appalling	Excellent	OK
Sharpness of RAW files	Mushy! But respond amazingly well to LR4 sharpening	Average, LR4 sharpening drastically increases noise	Unbelievably sharp, no need to sharpen further	Good	OK but come good with LR4 sharpening
Colour of RAW files	Rich and accurate	Slightly washed out but accurate	Stunning but not nessesarily accurate	Washed out	Fantastic, rich and accurate
Issues	Big and heavy	Lack of resolution is an issue but only if making large prints	Noisy over ISO 400 ( apparently)	Quality of files OK for tiny sensor but cannot compare to the others here	No macro
	Encumbered with worthless bloatware	Ergonomics not great, particularly fiddly 'enter' button	Some weird Foveon artifacts on high contrast edges and colour blotchiness on skies		Hesitant AF
	Complex autofocus system	Messy GUI but OK	Needs special software ( Sigma SPP)		Pathetic OVF
Likes	Unbeatable general purpose image making device	Full of character, discrete, charming, I have taken some of my best photographs with this little beauty	Stunning, jaw dropping resolution and 'pop'. Images have a definate character, scream 'Foveon'	Minisule, pocketable	Fantastic image quality
Conclusion	Respect for this camera, I doubt I'll ever buy another DSLR, for telephoto and macro indispensable, fast and easy to use.	As indicated above, it has some minor issues but these don't really detract from it's charm. Enables me to take wonderful pictures which is what it's all about, end of the day.	A 'one trick pony' but OMG, what a trick! Images have a magical quality that defies description. Astonishing and bewitching.	A solid and tiny little camera for those occasions when there is not room for anything else, amazing macro capabilities, fast lens is good for low light and files look nice in monochrome	As a small general purpose camera that makes superb quality images its fine, not as bad as many people make out as it is saved by the extraodinarily high quality of the files it produces.
