I have an NX300 which I like very much and my question is simply whether the NX500 is enough of an advance to justify changing. Ideally I'd like an NX1 but financially it's out of the question. Apart from the lack of an EVF, a non-issue for anyone who uses the NX300, the main criticisms of the NX500 seem to relate to its video capabilities. Since I'm a photographer and not a videographer that doesn't bother me at all. Otherwise it looks as if the NX500 gives you most of what the NX1 offers for about half the money. Any thoughts or comments?
