Beamer: change size of figure caption

Question

I am creating a beamer presentation and I would like to change the size of the caption under the figures. I am using the Madrid theme.

I tried the obvious way:

\caption{\scriptsize{Text of the caption.}}

and

\setbeamerfont{caption}{size=\scriptsize}

in the preamble of the document.

However none of that seems to have any effect.

I'd like to see an example showing that \setbeamerfont{caption}{size=\scriptsize} doesn't have any effect.
@GonzaloMedina: right, that works for me, except that I can't multiply the size. I'd like 0.7\scriptsize, but that actually prints "0.7" before every caption...

Use the caption package: \usepackage{caption}

Then use captionsetup: \captionsetup{font=scriptsize,labelfont=scriptsize}

Have fun with LaTeX!

	This doesn't work for me, I get an "undefined control sequence" error. – naught101 Apr 29 '12 at 5:57
	You have to use the package 'caption' \usepackage{caption} – user15608 Jun 14 '12 at 14:11
	Also, you can restrict this to figures by using the 'figure' option `\captionsetup[figure]{font=scriptsize,labelfont=scriptsize}`. – naught101 Nov 5 '12 at 1:06
