While apertures like f/1.4 are totally normal for full frame and APS-C cameras, they are almost unheard of in medium format, where most lenses open as wide as f/4 or maybe f/2.8. And so, that makes the Mitakon Zhongyi Speedmaster 65mm f/1.4 quite the intriguing lens right off the bat. Add in its very affordable price, and it becomes an option almost every Fujifilm GFX user should at least take a look at. This great video review takes a look at the lens and the sort of performance and image quality you can expect from it in usage.
