    Quick question about a lens

    Hey guys! I'll keep it short. I need a lens for real estate photography/ videography. I have the metabones speedbooster for Nikon on my GH4. How would this lens be? How can I calculate my effective focal length for videos/pictures?

    I would guess you multiply the focal length of the lens by 0.7 or maybe 0.65.
