Frage von Blinky5355:
Hello,
I want to run a 0.5-fold s.meiner Raynox wide converter of video camera, and although with a UV filter. If the filter is screwed onto the converter, there is slight vignetting in the wide positions in the corners, so I can not use this filter without reducing my wide angle something.
Now my question:
Are there any visual drawbacks if the UV filter between the camera and Converter is screwed? Then if the UV-filtered portion was just as good as if the filter is located on the converter?
I've read some reports and durchgeforstet forums. The answers range from "no" and "yes" and "why not", so I am not any farther in this matter.
Can one of you help me? Who has tested this before? Would be great if I could uneasy about an answer.

Hello Blinky5355,
clearly stated: Between Camera and Converter
heard a filter, because the air layer between them and affect the converter itself already the optical imaging performance.
The filter, therefore, belongs to the converter.
You will be here in the forum, I would say do not get a different answer.
Whether UV-filter because of the filtering of just this portion are needed at all, or any other filter (clear glass or infrared) is not as good enough, is probably often a matter of faith.
I myself have a UV filter (without the converter in front of the camera, with converter just before that), but more as protection of the lens - this is probably synonymous to most of the reason to take even one.
Moreover, any converter that affect each filter to the picture, whether you view it, or is only metrologically ascertainable, is another question.
You do not write what camera you have. Is perhaps a filter between the converter and reducing ring, which could be responsible for the blockage?
Synonymous You must remember that sometimes a Spacer between Camera and converter is necessary, so for me. And then a filter in between? This is not absolute.
Antwort von Bernd E.:
nicecam has really said everything essential, therefore, only a small addition: For exactly this purpose (avoiding vignetting), there is an extra filter to narrow the so-called "slim" versions. You can even time with your dealer to test whether it would solve the problem.
And you care about the equal opportunity synonymous s.besten a matching lens hood: Wide Converter are very susceptible to scatter, and certainly if there sits a filter in front of the front lens.
