100-700mm zoom?

Does anyone even make one for Canon bodies with the EF mount?

 

nope. Why do you want such a zoom?

 

Build muscles. Why else? :lmao:

 

I was going to say, don't many of the super zoom lenses show poorer image quality at both extreme ends of zoom/wide angle.

You're better off with a collection of smaller range zooms or primes with nicer glass.

 

Sigma make a 300-800mm F5.6 which is amazing but at about £4000 it should be

Idle curiosity more than anything.

Tamron makes a 200-500 zoom for under $1000 US, and it is actually supposed to be quite sharp wide open.

 

Canon EF 100-400 5.6L with a 2x extender is the only thing I can htink that might work
