The widest setting will likely be 24mm (equ) just like the SX30 predecessor. The long end will be 840mm. Looks like the SX40 will gain the BL-CMOS sensor from the 100HS, 300HS, and 500HS, and the SX30 will pass it's sensor down to the SX150, and the S100 will have a longer zoom than the S90/S95 that came before (5x vs. 3.8x). Hopefully the S100 will continue with the f2 on the short end. The 5x would seem to indicate a wider short end on the S100 (24-120mm) than the 3.8x on the S90/S95 (28-105mm), or could they be thinking about adding it to the long end only (28-140mm)? Another inch forward for the Powershots, yippee. Honestly though, I think Canon makes the absolute best P&S cameras on the market so little improvements don't really bother me.
