It also has an aperture with eight wings and two controls that allow you to replace the plates with heart-, star- and snowflake-shaped ones. This is a pretty tricky feature, but could be a hit for wedding photographers or baby photographers.
Lomography Sets Petzval Lens to Video Shooter for the First Time Focus marks and change the iris continuously (brass versions only). This is a smart idea, because I could imagine using such a lens for dream sequences, and it's a great option for wedding and event videographers looking for a unique look.
Since Lomography unveiled the first Petzval lens in 2013 (based on the original 19th century model), many more models have been added to improve quality and refine the look. If you're interested in this vintage look, both on the photos and on the lenses themselves, the Petzval 55mm 1: 1.7 MK II Art lens will be available in August for $ 449 and $ 499 in brass and black brass, and off Aluminum in black will be available in July for $ 399. As mentioned before, the brass options have a stepless aperture with no brightness jumps for video recording, while the aluminum look has a regular aperture.
