You want to follow the herd, you need – with some excellent reasons – a mirrorless. Well, actually there are so many options, I felt it was important to over simplify the landscape just to explain it with simple words. I don’t claim having right, I am just giving my basic opinion about main mirrorless cameras. So let’s start the show:
Olympus OM-D E-M5: an ugly name for a great body and a very mature system. If you don’t understand anything to the mirrorless’s mess, just buy this one. It is great.
Sony NEX-7: the best body. Best quality image, best controls, great look. Too bad, the lens systems sucks. Forget it until Sony will propose lenses good enough for such a jewel.
Sony NEX-5N: a great body too, but the lens systems still sucks, like for the NEX-7, that’s the same system.
Nikon V1 or J1: like a point and shoot, but bigger and more expensive. Great Autofocus, great video. Perfect for your kids, what most photographers like to shoot at. Controls sucks if you want something else than a fully auto mode.
Canon G1-X: that’s a compact masquerading the quality image of a mirrorless. Canon sucks trying to avoid cannibalization of its DSLR sales.
Fuji X-Pro1: a great body, my preferred one actually with Sony NEX-7. Great lenses but my preferred focals are missing (35 mm equivalent FX and ultra-wide angle). Too soon unless you like a 50 mm (equivalent FX) and are pleased with a non ultra wide-angle. The 3rd lens (90 mm equivalent FX macro) is great however. If you don’t like fixed focal, this is not a body for you, not just right now.
Leica M9: the price sucks, And not only the price. The body is really outmoded in many ways by newcomers. Leica still believes that “with great strengths come great weaknesses”. They should buy a DVD of Spiderman, they misundertood the quote.
Samsung 3 bodies NX1000, 210, 20: they are OK. Like Raymond Poulidor, they are never the best but always close to the best. Which makes me believe they suck too because there is always a better choice. Only their publishing services really rock.
Panasonic with bodies DMC-GF5, GX1, G3, GH2: failed to have the best bodies, but all are good (GH2 outmoded and to be replaced by a likely to be great body GH3). The lenses system is the best, but expensive. Buy a Panasonic body if you need several great lenses. High end bodies and lenses threatened by Fuji X-Pro1 system.
Pentax Q: the smallest sensor. Like a point and shoot but much more expensive. Funny if you have an unlimited budget or if you work as a secret service agent with the need of a tiny versatile camera. Not convinced yet, the lens system must improve to justify the costs and to explain why not buy rather a Canon S100 or a bigger mirrorless.
Pentax K-01: too bad its main strength seems to be its look. Not a bad body though, but not the best. A good choice if you like nice cameras, not my choice however. I like to take picture, not to attract attention. Cameras are not sun glasses.
There are a few other bodies (Other Olympus bodies but OM-D E-M5 have outmoded sensors but are still good cameras, Sony NEX-C3 is a good entry level mirrorless, but too big for a beginner omho), not my best choices.
My advice: read more in details reviews of these cameras, and if like many people you don’t have so much time, focus at your preferred choice.
