You make me wonder whether I need to change my G11 at all. Especially after Canon serviced it and checked focussing and replaced the faulty back. Maybe I just need to be more careful how I use scenes ie not at night and with macros to remember that autofocus seems to refuse to work on telefoto only on wide angle.
I hope it's because of my pictures.
Kidding aside, G11 is a great camera. Small enough to bring anywhere but good enough to take great photos. Oh and I love the swivel screen. I came to appreciate it better when I'm doing these macros. I know there are better cameras out there, but I can't see any reason to upgrade especially that I have my 500D as my main camera for all those times G11 is inadequate. As for 500D, yes it's quite old also but I don't really mind. Of course, if somebody gives me a 5D2 or 5D3 for my 500D, I'll switch in an instant.
I'll say, cameras are just tools. It's still us photographers that takes great pictures.
