The textures on those came out beautifully - super lighting. Just a thought you do have your Minolta set to: 'Focus = Continuous' in the main menu. If not change it to that it will mean the camera focuses while you are composing the shot so will be much quicker in getting the focus when you start to shoot.

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.
