May I ask if someone could explain a bit what this crop factor really means? On the metabones website, it says after using the speed booster, crop factor for BMCC and BMPCC will respectively become 1.53x and 1.75x, while the former means full-frame. In effect, after using the speed booster, is there any noticeable difference between these two? Thanks a lot for answering!

Thank you for sharing your thoughts! I'd like to ask a newbie question: since BMCC has an MFT mount, adding a speed booster like the "metabones Canon EF Lens to BMCC Speed Booster" will mean to use EF lenses. But then should I always use the speed booster and buy EF lenses or should I buy MFT lenses? Thank you!
