Frage von anonymchen:
Hi Folks
I'm on the front of my lens, wide angle lenses a small hairline crack, he's only about half a centimeter long and is quite happy for the Lens s.Rand almost to the fixing ring (only par millimeters away) - makes the fortune garkeine problems in the Picture.
But now my question: Is this still cracks propagate and even he was allowing it to spread that he is almost continuously (all of s.Rand fixing ring for fixing ring), then anything can happen right?
Thanks schonmal s.alle respond.
Antwort von beiti:
Sowas I've never heard of. Are you quite sure that it is not just a scratch?
Antwort von Gast1:
If there really was a crack, that would be visible in the picture with security as the light refraction.
Antwort von Phyro-Mane:
In fine hairline cracks not necessarily.
Hairline cracks are usually stress cracks.
Therefore, a crack can then expand next. Either "just like that rotation stresses," even in mild or mechanical, lay on the table, etc.
Antwort von anonymchen:
Na sharp ..... ; Spread (to what extent?
Antwort von anonymchen:
hm, maybe it is but not a tear because I'm testhalber straight times with a plastic handle of a screwdriver draufgeklopft exactly (on the tear something solid) and the synonymous Lens knocked lightly on the table and he has not enlarged, however, then at least No rupture?
Antwort von Phyro-Mane:
That does not mean anything.
I say it MAY be extended next.
But if you really want to have the lens is broken with Propeller on it or knock on the table exactly right.

Like a time bomb ... it makes me mad, well, what can you do, weghaun if not I will still bildqualitativ ok to sell with the crack is not in it more so I'll just keep it ... maybe someday make it stop times "zr" and the crack goes through the whole lens, like a time bomb, not a real good feeling with the ding, full of stupid * sigh *
Thanks anyway here s.alle

eventually makes it stop maybe once, "zr" and the crack goes through the whole lens, stupid like a time bomb, not a real good feeling with the ding, full Or did you buy a new lens, you rejoice for two days and they can s.dritten fall day. : (Everything is transient, but pronounced dead may live longer than expected.:)

Here, once a Picture with ~ 10x magnification: http://people.freenet.de/d-hendrich/galerie/Kratzer.jpg Hard to say, or rather, I do not think Glass Mushroom times since it was networked.
Antwort von beiti:
The thing indeed is not of edge to edge, but runs parallel to the edge. Furthermore, I see nothing to suggest that it goes into depth.
Is very likely only a small scratch. That speaks synonymous shape of the notch (the guys from CSI could probably figure out the scratch tool:)).
Antwort von Phyro-Mane:
Voice to him. For a crack the whole thing is too superficial. A stress crack could go deeper.
If it really, really bothers you: Sowas can be polished away as an optician. Does it stop at a tiny distortion in the picture, depending on how historic the optician.
Antwort von anonymchen:
Well I once heard is not polished away is just as good then because of the distortion s.der place, because then there etc.Eigentlich clear the beam steering or vote may no longer matter if you take away? So I will leave the scratches wiegesagt Chen, Fortunately, he makes any quality problems! Well with one exception: In a certain strong macro setting, there is a tiny fuzzy mini s.Bildrand spot, but for macro I screw the wide Anglesowieso usually better S.Weiler otherwise the autofocus is not as clean working (no idea why the so - is??)
I'm glad that it is after all only a forseeings Kartz!

If it were a precious vase, I would have polished away the scratches. :) For a Lens brings the (technical) dictate otherwise.
At a certain strong macro setting, there is a tiny fuzzy mini s.Bildrand spot I had a digital camera with MF-converter. As could be to focus in macro position even on the surface of the front lens (ie, the dirt / scratches) make it the main object. Here it should be similar. The closer to the Control pane of the front lens, the more sharply formed from your scratches. Therefore macros rather do (if possible) with telephoto.
Antwort von Markus:
I agree with the view that it is probably just a scratch. So it looks to me like the picture at least.
If it really, really bothers you: Sowas can be polished away as an optician. Of these, I would refrain, however, weil .. see
scratches on the lens.
