Third-party lenses are wonderful things. They prevent us from being locked those manufactured solely by the company that makes our cameras. It provides us with options that the camera manufacturers don’t even offer. For some systems, though, they don’t always offer the same feature set as OEM lenses. For Micro Four Thirds, that sometimes means no automatic aperture.
Laowa’s original 7.5mm f/2 lens for MFT was one such lens. So, they’ve now announced a new 7.5mm f/2 lens for MFT which updates the old one with automatic aperture capability, allowing you to control your aperture from the camera itself and have that setting stored in the EXIF data of your images.
