Canon has today announced two new Image Stabilized EF-S lenses. Utilizing an all new and considerably simpler stabilizer system these two lenses are virtually the same size and weight as the lenses they replace / upgrade. These two lenses in a 'combined kit' form would provide you with approximately 28 to 400 mm equiv (14.3x) field of view, with image stabilization, on an EF-S compatible Canon digital SLR (such as the Digital Rebel XTi / EOS 400D). No word on price for the 55-250 mm IS at this point but the 18-55 mm IS should be $199 when it arrives in October.
Phil: This new IS system appears to be based on some kind of analogue feedback system, although obviously Canon aren't revealing exactly how it works the diagrams found below tell some of the story. We are told this new IS system is just as effective as the existing Canon optical IS systems.
