Use an old FD lens?
Discussion
That looks stunning. Very nice. 
A quick scan of eBay shows stacks of these lenses up for grabs. Just put a bid for one here in Vienna for just €20. I guess I need to then buy an FD to EF adapter which can't be expensive....
I take it when you use one of these lenses, you have to set the aperture on both the camera and lens at the same time?

The camera doesn't recognise the aperture set on the lens, as there is no electrical connection between the two.
Setting the aperture on both the camera and lens doesn't work because under normal conditions the camera will meter with the lens fully open. Leaving the FD lens fully open for metering won't work either because the camera needs to know what the maximum aperture of the lens is; this information isn't available to it from the FD lens due to the lack of electrical contact.
The best you can do is what used to be called 'stopped down' metering. Because the camera can't read/set the aperture, it just measures the amount of light hitting the sensor, and sets a shutter speed as necessary for a correct exposure.
What I have found with mine is that this doesn't work consistently across the aperture range. It exposes correctly at f/4.0, underexposes by 1/3 of a stop at f/2.8 and overexposes by 1/3 stop for each stop up to f/22.0, by which time it's overexposing by 1 2/3s of a stop.
Haven't quite worked out why it would be doing that at the moment.
