Hi, would anyone have input as to the image quality difference between Mamiya 67 lenses and Pentax 67 lenses? From examples on Flickr and Instagram it looks like the Pentax lenses tend to have more macro contrast and a more abrupt falloff of focus, creating a more pronounced 3D effect. The Mamiyas to my eye seem to look less punchy, with a lighter touch in resolving fine detail, and a gentler fall off of focus. Does this line up with the working experience of others?
