[Tested on 42 MP camera] It is a lens with character. It’s not sterile or clinical, but has an analog, vintage character that I find warm and welcoming.[...] I personally would choose it over the Sony Zeiss 55mm F1.8 for the simple reason that I like the feel of the images more (and also prefer the focal length). The Sony is a little sharper in the corners and probably more absolutely sharp stopped down, but the difference is not significant.
