Frage von Mattheo:
I have 1 week a new UV filter of Hama, 72mm thread growth because the old one was scratched.
Joyfully I him on my Canon XH-A1 and start s.auf turning to go. When I make a swing of a bright light source from doing shows in the picture besides the normal lens flare synonymous another phenomenon which I could not really determine. Circles on the picture, but without the typical Lens Flare Color.
In the interior the whole I try again, hold the camera towards the lamp and draw the focus to the strange incident and then I notice: the lens of the camera is reflected in the glass of the UV filter .... I've never seen it and I am completely new.
Now the big prize question: Filters give back and complain or to live with because it's at for new filters is always so?
Perhaps what went so wrong in production.
Danke schon mal für eure tips.

Filters with Multi-coating, it should hardly be so strong reflections come. Does your filter, such a coating?
Actually UV filter are not necessary and only deteriorate the optical quality of the lens. However, can possibly be used in situations where you fear for the integrity of the front lens must have

Joyfully I him on my Canon XH-A1 ... Hello,
The XH-A1 may be a bright labeling s.der front of the camcorder optics and it is they who are against the maps? - If the cause should be thinking about a matte black coating to ... ;-)
Antwort von Mattheo:
@ Domian
on the coating, I had not thought about. Can I just at the moment, but absolutely not saying that because I'm just turning on and the remaining data for the filter did not exist and the names s.filter directly to find out nothing was.
Even if he has no multi-coating, I find it strange that he Lens of the interior reflects.
@ Markus
Labeling it is definitely not his, 1 I see in the picture is exactly what the lens is and 2 behind the filter is not a bright label affixed. The cause is definitely the reflection of the lens on the inside of the filter.
Antwort von Schleichmichel:
Meanwhile, each filter should be remunerated. But even the best compensation is no good if a strong light source swivels.
Actions: Compendium lens hood and pans and to refrain from light sources. Possibly. the swing without filter realized. Inscription on matt black paint was synonymous a good proposal.
Antwort von domain:
A problem with all the lenses in the retro-focus design is that the wide-angle effect in the manner of an inverted opera Guckes reached, namely with a Konkavlinse as a front lens and a generally more convex, thus magnifying looking next part.
True wide-angle lenses to build a very short and have no Konkavlinse front synonymous and thus not a "dust problem" as we did with our video cameras can observe.
In wide-angle position is that dust is not really sharp, but still clearly visible on the sensor displayed.
In this respect, each filter, so again the next few mm in front sits an additional problem (dust or reflections will be even sharper shown) and also there are two more fragile glass surfaces added.
I have with my FX1 until recently, once again a few shots against the blue sky spoiled because I have the front lens previously had not scrupulously cleaned.
For this reason I would never come up with the idea, I have further problems filter through unnecessary aufzuhalsen
Antwort von Mattheo:
Everything right and good, but proposals relating to the Compendium of pans and Avoid light sources by:
In concert recordings, it is highly impractical, for example, a compendium s.der camera to have the idea of a compendium of acquisition is already done and is synonymous to happen, but for certain shoots rather impractical. In concert recordings, but it can not be avoided if, for example, on the stage of blind to use in bright light sources to film, just here from headlights of a light reflection in the camera appears to call. And in tight spaces with a lot of public transport, I prefer the actual lens through a filter or the like to protect.
Scratches on the lens are then more likely unwiederruflich on which he is replaceable filter.
For other shoots where time and rest (which, unfortunately, synonymous rarely the case) can of course leave the filter off, or when an appropriate swivel unscrew.
What irritates me is still the reflection of the lens, because I had previously simply not seen, seems to be synonymous here but no one can really explain.
Antwort von Markus:
There were UV filter synonymous earlier times in a Ghostless version. There was the curved glass surface, such as to eliminate reflections. This type, I have no longer seen (relation between "was relatively expensive" and "stinginess is cool "?!).
