Shoot, shoot, shoot! That's the best you can do with a camera. And compare the ExIf from the shots you made with different settings to see what works best.
The thing is, with DSC H30, I loved its super zoom range and with XA10, I am limited to the kit lens.
People always look at how much a camera can zoom in. And although it's very useful in some cases it's always better to use the manual zoom (read: walk closer towards your subject).
I had a cool photography beginners training that covered both technical as composition subjects. I will look it up for you.
I love lunar photography and with DSC H300, it was possible to get an extremely close up look to it. So, now I need to get extra lens just for that hehe. I'd appreciate if you can find the beginners training and send it my way. Suddenly, this all becomes a new hobby to me once again.
