Two short video samples (below) testing out the Tokina 11-20mm F/2.8 (with an old metabones speedbooster) on the Panasonic GH5 Camera.
The lens remains rectilinear (straight lines) even at the widest setting, and combined with a focal reducer you're actually faster than an F/2.8 (which is better for dim lighting). I believe if I upgrade to a more recent Metabones XL Adapter, i'll get sharper results. But it's pretty darn good as is.
For moving the camera, i'm testing out the CAME-TV Prophet Gimbal which is designed to fly heavier camera setups. The combination of speedbooster and Canon EF type Lens may be a bit heavy for the smaller Optimus gimbal.
With cameras dropping in size with sensors smaller than your typical full frame from a Canon DSLR, shooters looking for a fast wide lens like Tokina's 11-16mm F/2.8. It's been one of my favorite lenses to use on the BlackMagic 2.5K, BlackMagic 4K, BMPCC, and even Sony's A7s. A must have lens in my book. Now Tokina has taken this lens a step further offering more focal range in the new 11-20mm while still maintaining F/2.8 across. The new lens has been announced for pre-order today and available for pre-order now (here).
