The Contenders: I've narrowed my search to two cameras, the Panasonic Lumix DMC-GF2 and the Sony NEX 5.
I want to move to a Micro Four Thirds (4/3) camera system. The size of the camera is small enough I can keep it and a couple of lenses right in my purse without having to carry an additional camera bag. Size is why I decided to let my hubby have my Canon T1i DSLR body I just purchased last year. More than it is heavy, I don't care for how its size feels too obtrusive at many of the events I attend, especially when other professional photographers are the official documentarians at said events. Smaller (less obtrusive and lighter) than the T1i and more powerful than my current point and shoot, with the option of using interchangeable lenses? I think a 4/3's camera is exactly what I need.
But which one should I purchase? Currently I'm leaning strongly towards the Lumix. But...
The Sony is faster and, most importantly, has a significantly larger sensor and higher resolution. I feel like nothing should matter more than the sensor size.
So why the confusion?
The Lumix has a superior touch menu navigation system. The menu is important, because I often reset my white balance and exposure settings room by room when shooting an event and even as the lighting conditions change in a single room. The Lumix also has 4 image ratio settings compared to the NEX 5's 2 settings. My current camera has three and I adjust the image ratio constantly, almost shot by shot. For convenience the Lumix has a built in flash (the NEX 5 doesn't).
The Panasonic Lumix DMC-GF2
The Lumix also has far more lens options (19 instead of 3) including a 45mm / F2.8 ASPH. / MEGA O.I.S. Macro lens, and you know how I love my close up food shots and close ups in general.
What to do, what to do...
Perhaps the most important aspect is that I'm looking at this in terms of once I buy the Panasonic or the Sony I'm buying into a system. Are the odds better that Sony will come out with more lenses down the road, or will Panasonic develop a camera body (with a bigger and better sensor) that the lenses I purchase now will be compatible with later?
Lumix Micro Four Thirds Lens Options
So I'd like to ask: For the type of pictures I take for my blog, any opinions which would be the better camera for me? Or do you think either would work equally well?
