The Petzval Lomography X Zenit 85mm f/2.2 was designed for Canon EF mount cameras. This lens works with both analogue and digital cameras. The lens technology minimizes field curvature to allows focusing of the entire image. With this lens, you will get a focus area that is very sharp over a narrow field. There is then progressive vignetting towards the non-focused areas to assist in directing the viewers attention to the crisp and focused area of the photograph.
