I am starting to work on the review of the new focal reducer - Metabones Speed Booster Ultra, made again in cooperation with Caldwell Photographic,
company its founder - Brian Caldwell, was first to introduce concept of
focal reducers for mirrorless cameras, few years ago. Metabones Speed
Booster Ultra is replacing older version of Speed Booster, and I was
lucky to get one sample for testing.
I don't want to lead you through technical specifications and to re-write press release to increase the traffic. Instead, I ordered competitive focal reducer from ZhongYi Optics - Mitakon lens Turbo II, and together with my own Speed Booster I, I started to make comparative tests. However, If you are technical type and want to learn more about focal reducers, I would suggest you to read Metabones SB White Paper - http://www.metabones.com/assets/a/storie/Speed%20Booster%20White%20Paper.pdf.
If you don't want to read all those 29 pages in the link above, here is short explanation what is focal reducer, and why you might consider to own one. Focal reducer is opposite of tele-converter :-) or if you like - inverse tele-converter. Tele-converter is made to increase magnification, or if you like - to narrow field of view. Focal reducer does the opposite - it reduces magnification or if you like it widen the field of view. This is great simplification of technical description, but that's most important thing that we should understand. Click here to continue reading review on our new redesigned Verybiglobo blog
