Well thank you for the honesty and all that good stuff guys. Sorry to keep peppering more questions onto you all, but I am going to be making this purchase using my Best Buy credit card (pay it off in 12 months=no interest) and looking at their website, the GH-2 is not available there anymore.
A GH-3 package @ $890.00 is available, though, and I could get a Panasonic 12-35 f/2.8 for about a grand from them, roughly putting me at about the same price as if I were to buy the GH-4. Could that be a good starting point?
The one thing that I am conscious of, though, is that if I do decide to go full frame in the future, would the money spent on that lens be a wasted invest?
