Come on canon, make a production model EF1200mm f/5.6 IS USM L!

WHY!

Good point. In fact, canon should just throw out its entire telephoto lineup. People who want reach are obviously best served by just buying a 50mm lens and cropping.

Ha,Ha!! I'v done that!!

Jon,


They call it a non 1D body = 800mm goes to a 1280mm

Sorry for being so obtuse [^o)], but I'm not sure I understand what you're getting at.

1.6 Crop factor

Nice idea! Just one tiny little thing that comes in the way - how much would it be?


If for $3,000, sure, I'll get it even I don't need it at all. But if it's comes at a price which you can easily buy a little house, then NO, completely not necessary.

I was thinking something more like $30,000.

Yeah, maybe a little house is too much. But the one right now selling at B&amp;H used is a wholly $120,000!!![:|] I just can't think of any circumstance that I might confront to thirst for this lens as much as I would pay $120,000 for it - not even if I were a multi-millionaire. Considering the rather ridiculous price, there're surely better alternatives. i.g. getting the 800/5.6L IS lens for free in conparison, add a 1.4x converter results in almost the same focal length and it remains AF on 1 series bodies. Buying a 600/4L IS and add 2x concerter results in exactly the same focal length and AF on 1 series bodies, IQ may suffer though but still, can't imagine the difference to be worth $100,000...

That would be cool; maybe they could also develop a 500/5.6L IS USM as a low-cost wideangle lens. :-)
