Build quality issues with old Voigtlander lenses

Thanks, guys. I'm back with another question.

I have a Voigtlander 15mm f4.5 lens (version 2, leica M mount),  the front and rear elements seem to be loosely connected. The front element, which is integrated with the hood, is slightly loose and can be shaken about a millimeter. I've heard this is a common problem (wobble? Maybe) with Voigtlander lenses. I'm wondering if this issue will affect standard imaging. I'm concerned it could cause optical axis distortion.

if the video files can be seen, you will find the problem. I need some assurance as to whether this problem affects the shot?

No. It does not.

When take photos in reality world, everything seems to be fine. Hope it works well. 🙏

Not a common issue, as far as my copy is concerned, which is free from it. You may wish to check if the optical cell wobbles when you grab the lens by the hood.

I have the version 3 of this 15mm since it was released and still solid

自从这个15毫米发布以来，我有第3版，而且仍然很结实

I asked around in my local photography group, and some users have experienced similar looseness issues as I have. Others, as you said, are solid. Perhaps there's some malfunction here.

就我的副本而言，这不是一个常见的问题，它没有它。当您抓住遮光罩上的镜头时，您可能需要检查光学单元是否晃动。

Perhaps this is normal aging wear and tear on the lens, or perhaps it is a mechanical failure.

I purchased it twice, and each time the sample had varying degrees of looseness.
