Poor Petzval simulator lens

This lens is marketed to "replicate the famous Petzval." It's funny how the worst problem of the Petzval, swirl, has been turned into a feature to be replicated and enhanced.

I have posted ny comments there! No-one seems positive!

they have an imagon-type lens and now a petzval-type lens, and lenses that
allow the user to tilt-shift .. lensbaby makes fun stuff.

Regardless of your personal opinion on it, to many people, including on this board, swirl is the reason to have a Petzval. Me, I look at the results of any Petzval and wonder why anyone has one, swirl or not. . . but that's MY opinion. A couple of the other Lensbaby lenses are quite nice, IMO.

Yeah, i'm not too bent out of shape about it. I know why people like the swirl - because it's not "cell phone perfect." And that's rare.

But the center section of a good Petzval was what was used for 100 years. They cropped off the swirl, if any. The center is sharper and faster than any other lens, of the times.

There's always this one. I wonder if in their redesign, the accentuated the swirl.

Just way ahead of current scientific thought.

Light has a twist.

Only by replicating the Petzval swirls for the digital masses can we ensure it will become so commonplace as to be universally nauseating. Why should only the large format artistés suffer, when everyone can?

Ha! The first time I saw it, I thought, "Oh Cool! How can I do that?" and the 10th time I saw it I thought, "That makes me motion sick."

Those that don't know, there is another petzval clone just being made that is for large format. Supposedly the lens company analyzed a Dallmeyer 3B. They just shipped some prototypes to testers this week.
