A very good price (cheapest I have seen) for a very competent bridge camera (that handles like a DSLR). Even though it's a 3 yr old model, I still think it's very competent due to its full range F2.8 constant aperture. I have this camera and has served me well. It's weather sealed so it's good to bring it out for your upcoming summer vacation! I have owned so many cameras and DSLRs, this is the one I always bring along for great shots, due to the F2.8 lens.
It's not in the big league with full frame mirrorless cam, but you don't need to invest in great optics (which is always the most costly factor) for this cam, and at this price, it's pretty much a straight forward decision. Many places like Harvey is selling at $698, Ted at $749.9, Digital Camera Warehourse at $639. I'm thinking of buying a second one though as there doesn't seem to have a successor to this like a FZ400 or something (I could be wrong if someone can point this out).
Many reviews showing the excellent features
