Yep zoooooooooom is the way to go. Gives you more chance of the background being out of focus too. Good idea with the viewfinder, for the more active photographer, if it works on macro mode zoom, some don't because the lens gets in the way of the viewfinder.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
