Phillip Reeve So much is wrong with this lens, [...] The lens is super heavy, yet the build quality isn’t exactly great. Both rings are a bit scratchy with uneven resistance, markings are not engraved, the lens hood is wobbly and reflective on the inside. Sharpness and contrast at f/0.95 are far from good, especially off center. By f/1.4 the lens starts to show acceptable resolution and contrast, but there are many more reasonable 50mm f/1.4 lenses available the same and more.
