Well, I guess if none of you guys can see the point, that might explain why Canon can't, either.
Malcolm asked: What's wrong with Canon's EF 70-200 f4L? Answer: it's 200mm, as opposed to 400mm. Stick a 2x on it and it becomes a 400 f8, as opposed to the 400 f5.6 that I have. And sure, 200 x 1.6 is 320, but then 400 x 1.6 is 640. It's still a full frame lens, so wastes half the light. I realise that the optical difficulty is at the short end, but the weight is at the long end! There is some gain, of course, because the optical quality in the centre is always going to be better. Anyhow, no rumours, it seems, so if Canon don't want to compete, might have to start looking elsewhere. I guess they figure that anyone who wants a nice telephoto should buy a 5D to attach it to. Seems like a relatively short term strategy to me: there's nothing that magical about 24x36 frame size and a sensor that big is always going to be more expensive as are the lenses to cover it. They will also presumably always be a bit less noisy, but given how good noise reduction software is now, not much of an issue. Given a system costing, say, £5K and one costing £10K and weighing twice as much, I reckon most would suffer a tad more noise. There will always be a few lugging view cameras up mountains! No rush, my 10D still does very nicely. Peter -- The University of Stirling is a university established in Scotland by charter at Stirling, FK9 4LA.
