Trust me, "it ain't gonna happen" (with the glass you're talking about).
Also, even ISO 3200 looks pretty bad (on the cameras that have it). Sorry, but you're not going to find ISO 3200 that looks as clean as your ISO 100.
As for the media, forget it. The DVD formats aretoo slow.
Getting back to the Glass. Have you priced lenses for SLR's lately? Remember, because the sensors are dramatically larger, the lenses are too.
First of all, you won't find a lens for an SLR that starts out in the 30-40mm range, and goes to 500-600mm. Sorry. You'll need multiple lenses. Also, you won't find a zoomlens that fast.
In longer focal lengths, even "Prime" (non zoom) lens that are bright (and I'm talking F/2.8 )can get pretty expensive -- especially if you want IS (Image Stabilization).
For example, the Canon EF 300mm f/2.8L IS USM lens lists for$6,500.00, but you can find it discounted now for $3,899.95

600mm with IS? Try $12,000.00 list price, and $7,199.95 discounted (and that's an f/4 lens):

Look, about your lowest entry price for getting into a good DSLR, with relatively good noise characteristics, with relatively fast lenses with acceptable quality (that get close to the focal range of your Canon S1 IS),is probably something like the Canon EOS-10D, with theSigma 24-70mm f/2.8 EX, and the Sigma 70-200mm f2.8 EX APO IF HSM lenses.
This camera, with it's 1.6x crop factor and lens combination, would give youa 35mm Equivalent focal range of around 38-320mm at f/2.8 (no stabilization of course).
If you shop carefully, you could buy this package (Camera + these two Sigma lenses) foraround $2,500.00
However, then you're back to having a depth of field problem (less of your image in focus, as you get further away from your focus point). Remember, Depth of Field is based on the actual focal length of the lens.
So, your little Canon S1 IS hasdramatically more depth of field, at a given 35mm equivalent focal length, focus distance and aperture, than you'll get from these lenses. That's because it's lens is *really* only
5.8–58mm (to give it a 35mm equivalent focal length of 38-380mm).
