Interested in getting a Panasonic G5 or G6 due to SLR body type in a small package. I think the image quality is pretty much the same. Used G5s are going for $250 or less. Used G6 are hard to find but normally go for double the price of G5. So the question is, does the G6 offer enough upgrades over G5 to cover the price? I need: EX Image quality Fast AF specially indoors and low light Good Screen resolution Good EVF Easy to use dials / Menu system. Please let me know what your experience is, if you upgraded to G6 from G5.
