############################# Video Source: www.youtube.com/watch?v=B3ywLouK-6g

Every now and again I see comments on my videos from people who don't quite understand how Speed Boosters work. They're either confused about using a focal reducer on a mount that's incompatible or they aren't sure how it's changing the crop factor. Hopefully, this is a quick and easy way to explain what focal reducers are and how they work. • Metabones Canon EF to Sony E-Mount: http://amzn.to/2ehjgaQ • Metabones Canon EF to Micro FourThirds: http://amzn.to/2fpnRtZ • More at my blog: http://www.stronzvanderploeg.net/ • Facebook Page: / stronzv • Instagram: / stronzv • Twitter: / stronzv • Snapchat: @StronzV • Buying items with this Amazon link costs you nothing extra but helps support the channel: http://amzn.to/2dFRW82 • If you'd like to help support my channel, please consider contributing at SubscribeStar: https://www.subscribestar.com/stronz-...
