Well ... I'll make this real simple for you Canon-gurus ... NO IS ... NO MORE Canon CAMERA BODIES ... or IS-equipped lenses.
It's your choice, Canon ... you have me at "In-the-body-IS", otherwise ... keep the glass and the 40D, my bag is full. There is some "BUSINESS SENSE" for ya. I don't have money for coercive cop-outs. You want MY business ... then go use some sense.
If SONY pops for a full-sensor, IS-in-the-body offering ... I don't care if it is $2500 ... it's going in the bag! The Canon system gets sold and that's the end of this BUSINESS.
It only makes SENSE!
Actually...if you think about the price that you/others would really have to pay for in-body IS it might not be that attractive after all. So if they put the IS in body, the incentive to buy IS lenses would die down quite a lot. Where would canon make up the difference from? Pricing bodies higher...pricing lenses higher...and an off shoe cord might be $200. So we all switch to 3rd party lenses. This is a lose-lose situation for Canon financially. They can either sell less bodies and keep on touting the 4-stop IS...or they can sell more bodies and less lenses. For those with a 13 lens collection already, the choice is obvious. But the prosumer that's buying a first DSLR isn't going to want to fork over $1000 for a camera body, then buy a run-of-the-mill lens for $750.
