This is a fantastic lens & I'm generally a canon L lens type of a guy. That been said I believe in using the best tool that gets the job done.Build quality is really solid & the addition of VC is great, it's f2.8 constant aperture on Full Frame & it's the only on in the world to date with...
VC works great Silent operation High quality finish Good weight; balances well on 5d Mk11 Amazing image quality
Slight Vignetting Canon didn't make it first ;
