World's First lens adapter which can enlarge the image circle of Full Frame Lenses for using on Fujifilm GFX-50S
WHAT IS IT?
Laowa Magic Format Converter (MFC) is different from the simple GFX adapter existing in the market. The GFX adapter currently available in the market simply adapts the Canon/Nikon lenses onto the Fujifilm G-mount body with no resizing on the image circle. However, due to the relatively smaller image circle of Canon/Nikon full frame lenses, most of the them are not able to completely fill the Fujifilm GFX sensors, resulting in serious Vignetting (Dark Corners) or heavily degraded peripheral sharpness in the images.
HOW DOES IT WORK?
Laowa Magic Format Converter (MFC) took advantage of the short flange distance of mirrorless cameras and incorporated a patented optics system into the converter. The optics system successfully boost up the size of the 35mm format (full frame) image circle and have it fitted with the larger GFX sensor.
ULTRA-WIDE YET VIGNETTING FREE
Laowa Magic Format Converter (MFC) is particularly useful for ultra-wide angle lenses. Vignetting tends to be stronger when we adapt an ultra-wide angle full frame lenses onto the GFX sensors. By using the MFC, GFX users will be able to enjoy an ultra-wide angle of view without the need to crop away all the unusable corners of the images. When the MFC is used with our Laowa 12mm f/2.8 Zero-D lens, it will become a roughly 17mm f/4 lens in GFX-50S. The angle of view will be equivalent to approximately 13mm in 35mm format.
