This may sound like a stupid statement, but the Zeiss ZK-mount lenses sure are terribly similar to those "made" by Voigtlander. (design-wise)

Aren't they both made by Cosina now? (if they are, that would explain the similarities)

So once the lens is made by cosina, it is no longer classic?

Uhm, no. But it's not really a Zeiss anymore.

Here's a comparison with the Zeiss:



And here is a comparison with various Pentax lenses:
What is notable about Ultron vs. Pentax is that Pentax always places the concave element third, whereas in the Ultron it is the second.

I got it. Voigtlander does not spell like Zeiss. No wonder it is not Zeiss anymore.

There's no need to be ironic. It's not a German-made Zeiss lens. It's just a re-branded Cosina. Kind of like the Chevrolet Aveo is not really a chevy. Just a re-badged Daewoo.

That doesn't mean the lenses aren't good. (with that price tag, they ought to be)
