NEW LENSES for my Panasonic GH5 ⎜ Canon 100mm f/2.8L Macro ⎜ Tokina AT-X 10-17mm f/3.5-4.5 Fisheye

I've been thinking about getting some new lenses for my Panasonic GH5 for awhile now. So when a friend of mine said he's selling some of this used video equipment, I jumped at the opportunity to test two of his lenses first hand before deciding whether I want to buy either of them. 

The two tested lenses were: 
Canon 100mm f/2.8L Macro lens (see below)
Tokina AT-X 10-17mm f/3.5-4.5 Fisheye lens (see below)
And this is the Metabones Speedboaster XL, to be able to use the lenses on the GH5 (see below)
