I despised 4/3.
I waited nearly 2 Years for Nikon to release a fast, small Af-prime for my D40, nothing. Instead ever bigger and more expensive cams and lenses. The new 50mm/1,4 is too long to be useful as a walkaround.
I re-tried Pentax with the K200 and a Pancake, but too heavy, and the lens too long again. Now the K-m looks interesting, but hey, 200 gramms heavier (it's a lot) than the e-420, and the 40/2,8 remains to be a 60 which made me sell everything, not to talk about the slow menues.
So I bought the E-420 with the pancake 1 months ago.
Wow.
Love it. Small, light, fun.
Were it not for my own prejudice, I'd bought the E-400/410 way earlier, love the design and the idea.
With the release of the Pancake, I gave it a try.
Now I'm bought, I'm a convert. Gave my Nikon stuff away.
Maybe APS is doomed once FF gets cheaper!?
All is getting big, and if you guys want to carry all the fat lenses and DSRLs, go for it. I don't. (m)4/3 seems to be the right thing for me.
And you don't get anything like the Pancake, like an 14-54 from any other manufacteur. I'm sure more small stuff is to come.
