According to one Australian retailer...?
But I've always been a bit skeptical of the £3500 estimates, apparently based on previous 5D-series launch prices. What's that got to do with anything, other than wishful thinking? If this camera lives up to the hype then Canon can charge pretty much what they like and still sell every one they can produce, at least in the short-term, and in the current climate they probably need to make some fast money.
The R6 looks like it has the potential to be the bigger seller, so that's the one that must be keenly priced.
