GH4 + Speedbooster 0.64x, Sigma 18-35mm in 4k but still some vignetting?

I shot some blank background shots in 4k and upped the contrast. Even when fully zoomed on the Sigma 18-35mm, there is still a blurry vignette; almost like a radial gradient. Is this normal?

Images (again, upped the contrast so you can clearly see):

18mm

35mm
