Fantasy lens: 200-400mm compact F8 apo WR for high ISO future cameras

As ISO creeps up we could have great mini "long" lenses--- e.g. if the K7 "super" gets us up to ISO 25K or higher this kind of lens would be a shoe-in. -Sure, Bokeh is cool, but a 1970's 50mm F1.x will always provide Bokeh. Anybody else want compact and long?

I have a feeling that AF and metering would be quite unreliable with such a lens- whether it be F8 or F5.6-8. Can't defeat the laws of optics by increasing sensitivity! Then again, if Pentax can come up with a better AF sensor and winder metering range while they were at it, then we might be in business

This makes me wonder... How did Minolta manage to make an AF 500mm f/8 mirror lens?
