Metabones Announces New Speedbooster ULTRA

By Anthony Thurston on September 2nd 2014

Sharper corners, less distortion, and reduced vignetting. Those are selling points for the newly announced Metabones Speedbooster Ultra, which does everything the original Speedbooster is known for, but improves on it in a number of ways.

The new Speedbooster Ultra features a new 5 element/4 group design that improves sharpness across the frame (but especially in the corners), as well as reducing both the distortion and vignetting that was experienced in previous Speedbooster versions. The Ultra features ultra-high index tanatalum-based optical glass, which is of the highest quality.

    seems too much of an upgrade though.

    Maybe to much for an upgrade but definitely more incentive to get one if you haven’t yet. My main problem is they don’t have a Canon to MFT adapter yet (available for pre-order) and now this comes out and they don’t have one for Canon to MFT. As a hobbyist, maybe it’s not worth the cost, but GAS is such a terrible affliction. Argh.
