Revisiting my FZ35
There have been a number of occasions when I've looked at shots from a few years ago and concluded that the IQ of the camera of the time was just as good as my latest one ( I tend to have a dslr or bridge camera and a travel zoom at any given time)
On a couple of occasions I've even gone as far as buying a mint copy of the camera that I had several years before. I did it with an Olympus C765 and a Canon bridge camera. On both occasions I've concluded that the older cameras produced just as good IQ, but they did it at lower iso's, and they did everything more slowly from start up onwards. In the case of the Olympus 765, the LCD was minuscule by modern standards too!
Conclusion? Move on!
