Powerpak YONGNUO YN12-35mm F2.8-4M Camera Lens Compatible with Olympus, Panasonic and Micro Four Thirds (M43) Mount Camera,Black

Youngnuo never ceases to surprise with their innovations. My past experiences have been their products integrate perfectly with camera bodies they’re intended for, including the most difficult customer like Canon. The present one, with very useful zoom range of 24-70mm (full frame equivalent) operates just like a native Panasonic Lumix lens with g90/95 body. All operations from accurate focusing to focus stacking are smooth. Great Macro performance. Huge improvement over the 12-60mm kit lens which has much lower resolution but cost only slightly less if bought separately. However don’t expect resolution like Panasonic Leica DG lenses. This lens has almost no reviews yet. However already cost started picking up. Most likely a mkii will come in the market with higher price tag. Additional desired features include a nano coating and some weather sealing and firmware update port. Like their Canon EF mount products I am very hopeful about durability. The optics is complex with 11 groups and 14 elements. However a weight about 317gm gives an impression the image circle is APS-C size. However it should work with compatible M43 mount bodies perfectly without any vignetting. Kudos to Amazon marketplace for selling this incredible value for money product.
