I have a GF-1 and it served me well. I use it only with 20mm 1.7. Don't have any other lens. I do family photos, specially on trips etc. Other than that, I do photos of my modding projects Now G5 has a nice promotion - they add 45-150 lens for free. I was going to buy this lens, but now i may just sell mine GF1 and get new body. It has few new stuff in it, so thought it would be nice to upgrade. What do you guys think? Anyone tried this G5? Is it worth over GF1?
