Thank you for your comment. I know exactly what you mean, but the lens is just an instrument and can be used in different ways by different photographers. Those sample shots were taken to show the lens' ability to produce a "signature" swirls, but it is very easy to take a pictures without it, by using a smaller apertures, or placing the subject at different distances,or simply by cropping the final image. Using a smaller sensor cameras will cut the swirls off too. I'm sure you know what I mean - it is not always easy to get those swirls from the Petzval, but you can, if you want to.
