A very artistic set and you obviously understand the PX already and what it can do well. I thinks its strengths are portability, toughness and great colour rendering. It seems happiest optically at the wide end and 'graphic' subject work really well. I guess they were giving them away in Sydney?
Welcome to the PX club, Marcus, and have fun with it!
Here's an initiation rite for you :
You put the self-timer on 2 seconds, press the shutter, and throw it up in the air as high as you dare, the objective being a self-portrait. Best to try it while you're standing on sand at the beach at first...
I did it with mine, but no way I'll be showing the photo here, eh?
