For my personal opinion, I am satisfied with E-P1. Actually, it is not slim, light, and small enough; but the photo quality is just the same as all 4/3 cameras. Because of the same Live-Mos, Micro 4/3 could offer the same photo quality. On the other hand, I personally think it get a well balance of the first Micro 4/3 product. Not perfect, but acceptable.
Here are some photos that I took for your reference. E-P1 with 17mm (F2.8 almost) Picture Mode: Nature, Contrast 0, Sharpness 0, Saturation 0, Gradation normal
Thanks a lot~~~ your samples are very nice.~ very impressed~~~i am waiting for next weekend since i will get my salary~~~~ then i can go to pruchase the 17mm kit set~~~~~
If you expect to get a abundant replies, suggestions, or answers to your concerns about E-P1 from an online forum ‘in English’, you'd be better go other prestigious websites, such as dpreview and dcresource, which are built mainly for English speakers. You are right that it's your choice to use English here in mobile01, but you won’t get as many responses as if you did it in standard Chinese.
Just like in dereview, photographers come from all over the world but everyone sticks to English; in digitalkamera.de, users stick to German; in spreamedia.it, users stick to Italian. The language rule is so simple and self-evident when you surf across countries and cultures.
I believe you understand and are able to write in Chinese. So if I were you, I would find a way to make my computer at home Chinese compatible. The work should not be hard or complex, and it is worthy and once-forever. Then you will have overwhelming helpful responses to your concerns.
