[New Gear] Canon R7 with 100-400mm f4.5-f5.6 ii L

I recently got an R7 and just now paired it with the Canon EF 100-400mm. I actually can't believe how sharp this lens is compared to my Tamron 150-600. It's sharper at 400mm cropped than the Tamron at 600mm native.

The lens is heavy though, my wrist really start to hurt when holding it for longer periods of time.
