85mm Lens (Still Life)

I recieved my Canon 85mm lens a few days ago and I am in love with it! The build quality of the lens is completely different from my Sigma 50mm and the glass itself looks impeccable. I shot a pair of shoes that I own by Aldo and the details in the lens blew me away. This is all done one a crop sensor though, so I'm dying to know what it's like on a Full Frame sensor camera and whether or not the details are crisper and colors are more vibrant. I plan on having my personal portraits done Today (hopefully with no weather abnormalities) with the lens so I'll see how well this does with people as well.
