Sorry, it doesn't meet my strict criteria. Only up to 600 and 1.8...... I want 700 and 1.4....... and the price, well, is that negotiable ??
Not to worry, I have my Focal Length Extender and a Aperture Reducer in the garage....it'll be 700mm and 1.4 in a jiffy and I won't even charge labor....with that extra work, price is fixed

OH, I know, Nikon is bringing out a 10-780mm AF VR f1.4, 3 ounce lens for their new mirrorless camera, it will sell for $189.99. Boy, you are really in luck you waited aren't you?
I've heard about this. It's a special lens that Nikon is making for an EOS mount.

You are way ahead of your time. In the future, maybe near future it won't be a joke anymore. Think about our computer technology, evolved in a couple of decades.

Well, let's see.... the Sigma 200-500mm f/2.8 is about 10" diameter to accommodate a 178mm (7") diameter aperture, 28" long (without lens hood), weighs 35 lb. and costs $26,000...
A zoom with focal lengths up to 700mm and f/1.4 aperture will need to accommodate a 500mm diameter aperture - a little over 20 inches - so the lens itself will need to be around 26 inches in diameter, probably about 75" long (without lens hood) and might be expected to weigh somewhere around 120 or 150 lb. I'm sure you can get someone to make you one for around $500,000 (US).

That makes me a prophet, a seer of things to come. Not a simplistic fool like over half of the responses would suggest. He who laughs last, laughs best.

I have a Canon EOS mount and want an all purpose lens. These are my criteria: Focal length from 10 to say 700mm, fixed aperture of 1.8 or better yet 1.4, autofocus, image stabilization, weight not more than 5 ounces, price not more than $300. What do you suggest ??

If wishes were horses lenses like this would exist and be available. For a minute I thought you were joking.
