Hi Ian - I wish I had thought about this sooner and I wouldn't have traded my Lumix G1 in because I only got a pittance for it. The G1 served me well for over 10 years (I bought it when I retired in 2009). I've just traded in my 100 - 300 zoom lens which I rarely used for a 35 - 100 which seems a better range.
Good to hear from you.
