Review and Grabs: Metabones Speedbooster Nikon F to M4/3 on AF100

[Boncrek]

Tamron 17-50 F2.8 has a slight vignette but looks great to me and is now what, a 12-35 F2 constant aperture zoom for £240 pounds!

Tamron 70-200 f2.8, full coverage.

should be arable to test the Olympus OM F1.4 in around a week (have ordered the mount swap from Leitax)

Does the Tamron 17-50mm F2.8 Vignette at all apertures on the Speed Booster? Or is on the wide end?
I had wanted to pair this combo with a Panasonic G6 but now I'm not sure.
Is there any video of this vignetting as well?

Thanks for the review on the SpeedBooster.

I just picked one up and now I'm kicking myself for not getting it sooner.

I already loved my AF100, but this just makes it so much better!
