I am a Canon user (not a fan, just a user) and won't be switching to Nikon but I think Canon just got served :-)
sj2: Lots of opinions and lots of people seem to think a camera should be everything to all people. No one camera will ever do that. It is a tool with specific application in mind.
To my mind, unless you are new in the market and have no lens/system, comparison with other brands makes little sense. I have been down the path of owing two systems and did not work.
Lenses are the real investment so to me, makes sense to build a good lens line-up that you enjoy working with. Then fit bodies around your lenses. And that what I like about this little fella.
I can pack it in my bag with the primary Canon dSLR body and lens and when I don't want to lug around the primary body, this little guy comes out and does the job.
Going to sell my m4/3 body and lens now. m4/3 vendors have simply wasted too much time with mediocre lens. If you are new buyer with no existing setup then Sony and Pentax seem like good alternatives except Sony's lack of lens. Nikon with a sub-APSC is a competition?
Overall, I don't get comparisons with other formats/systems unless you are a new buyer. I tried maintaining two systems and did not work for me. This is not to say that current M offering from Canon is perfect and yes, I would not buy it at list of $800 but it would be a welcome addition for me in terms of weight and size.
Regarding the viewfinder rant, I was in that crowd earlier. I have a VF2 for my E-PM1 that's mostly collecting dust now. One, I think an add-on EVF defeats the ergonomics of a small mirrorless camera unless it is built in. Two, I think Canon have done the right thing by providing touch focus/shoot while doing away with EVF. Having used the same touch/shoot on my iPhone, I found is surprisingly intuitive and would even say, it opens a different style of shooting. Sure, it can be disconcerting at first since you are used to the VF for decades but all I can say is, try it with an open mind. Like any other tool, some take time to grow on you.
@agray88 Yes, seriously :-) I agree m4/3 has few good primes. Not very fast but not bad either. That f1.8 aperture on APS-C isn't the same on the m4/3 so not apples to apples comparison. Consequently, f1.8 on m4/3 is slower than on APS-C (and APS-C is slower than 35mm and so forth).
On Canon, you not only have very nice prime lens line up but the L series of zooms are really good too. Can't say that about zooms on m4/3 which are slow and optically mediocre.
Don't get me wrong - I brought a E-PL1 to a trip to Hawaii, used it with a 135mm Pentax screw mount and thoroughly enjoyed it. I love the Olympus E-Px interface too and currently have a E-PM1 that I sincerely hoped would work for me. But every time I compare the pictures from the E-PM1 + prime with my Canon T2i + 35mm f1.4L, the m4/3 simply does not measure up. I am not really blaming Oly/Panny for all of it - some of it is physics - you simply cannot the same DoF on m43 as on APS-C and that totally changes an image's character.
Lots of opinions and lots of people seem to think a camera should be everything to all people. No one camera will ever do that. It is a tool with specific application in mind.
Nice camera and would jump on it if I wasn't invested in Canon L lens. I was looking at Fuji's announcement to add a light weight camera to my kit. With XPro1, I probably could live with the weight (200 gms more than my Oly E-PM1) and size (after adding a EVF, the Oly E-PM1 sizes up the same) *BUT* for the price tag on this camera plus lens, I can buy two more nice L lens - 135mm L and 400mm L to be specific :)
But I am glad to see some good, high quality competition to Canon/Nikon. Unlike Sony NEX, Fuji's putting out good/fast lens and unlike Oly/Panny, the XPro1 is a complete camera with a great sensor and built-in EVF. Kudos to the Fuji team. Please please price it lower, pretty please! :)
Nice but background is busy and distracting. Should have used bigger aperture / smaller DoF.
Very tempted by these Sonys. Very impressive line-up but I am going to say no. Sony is pure evil.
