The image on top (Source: Quesabesde) shows the reason why I still prefer the m43 system over the new Nikon CX mirrorless cameras. While the [shoplink 23565]Olympus E-Pm1[/shoplink] you see on the right is using a larger sensor it is still less high and less thick than the Nikon 1 V1! Beside that I find the Olympus E-PM1 design far more sexy :)
Before you start bashing on me saying I am a fanboy, well I am NOT! I use cameras from different manufacturers and there are many things I like from the Nikon camera world ([shoplink 25651 ebay]D700[/shoplink] and many of their lenses). But I simply cannot fell in love with the today announced Nikon cameras. The image quality of the V1 is good, but not as good as the one delivered by the m43 cameras. Check the ISO comparison at Focus Numerique. One more thing. The Nikon 1 V1 costs $899 on Amazon (Click here)! That’s $400 more than the price of the Olympus E-PM1!
Anyway, I am glad Nikon entered the market. More competition we have better it is for all of us (P.S.: Panasonic, can you please lower the price of your lenses and make them available earlier?)
Note: This is my very personal opinion. Other may have other needs and reason to like or NOT to like the new Nikon.
P.S.: E-PM1 shop links at [shopcountry 23565].
UPDATE: Here is a size comparison with the GF3 made by Colorfoto.
