I needed this lens converter for the wideangle interior photography Lumix G Vario 14-42 on the lens. It did'nt work properly enough, but I give this one to three stars Because some of the photos in a good lightning were usable, even good. I also tried a brandless 0.45x Converter lens, but It was not as good as this. Finally I bought a Samyang 7.5mm F3.5 for MFT, and it works nicely (4 stars for it).
