Surely the latest bodies are arguably the 'best' while also the most expensive. However, seems the 1-year-old bodies are very good, relatively inexpensive, which leaves more money for lenses. I've always been a fan of having and working with two bodies. Last week I purchased a GX1 and two lenses. Since the beginning I've considered purchasing either a second body or a add-on viewfinder for the GX1, which brought me to consider the G3 for $300. My arguments/rationale in favor of buying a G3: -Viewfinder: for $100 more than a GX1 viewfinder alone, I can have an extra body, viewfinder, articulating screen!... seems very worth it. -Battery. Appears the GX1 & G3 use the same battery, very practical and useful for a two body kit to use the same batteries. [My Canon 5D and 5D2 use different.] -Price. $300 is inexpensive (with a lens I might sell), and I'm trying to spend less on bodies than lenses. All these bodies might be junk/discarded in a few or several years, as the newer stuff comes out, then is discounted 1-2 years later, just like the current G3. -Small. I like the small size, my main reason to try m4/3 was to get small again. Bigger than the GX1, but maybe not too much? -User interface: Similar to the GX1 that I'm already getting accustomed to. Negatives: -It's not the latest body with the most features? What else am I missing here? Any other glaring differences compared to my GX1 other than it has an electronic viewfinder and an articulating screen?
