Plants look awesome, xcrispi!
There should be a "landscape focus mode" slide switch on the front of your camera. Make sure it's on the setting that looks like a little man icon, not the mountain icon.

Also according to the manual for your camera I'm reading online, the digital zoom is only available when you have the LCD on, so make sure it's on when you try to zoom in with it. Also you have to be set to 2560 x 1920 mode for digital zoom.

Not sure what else to tell you, here's the link: http://www.fixya.com/support/p218414...l-15206/page-1
