Frage von Damien:
Hello
I have for my JVC GR-DVX707 a wide-angle (and synonymous tele-) objectively purchased (Kenko 0.45 x).
Now I have to question whether it is normal that the rounded edges of the lens is in the corners of the picture I sieht.Wenn zooming you can see the edges-longer, but then so is the advantage of the wide-angle unused.

Hello Damien,
This shadowing s.Rand called vignetting and is a mapping error, which, of course (!) would not have.
What are you on your next purchase additional lenses should pay attention as ...
is in this posting. ;-)
Antwort von schmili:
I have the Kenko fisheye synonymous 0:45 am and for the low price but very happy. I have mainly used for skateboard shots because vignettes had no particular problem. If the disturbing side, however, moves and it looks as if loose parts hanging in the Picture, then necessarily switch from the digital image stabilizer!

the objectively a thread of 37mm and 27mm has my cam ... on what I would have to pay attention so that there is no vignetting (if I want a new objective ...)??

The best you go into a shop and try on the eligible Any additional s.Deinem from your camcorder. Why, that makes sense, is at the top link next posting ( "Since the overall performance of the optical system ..."). ;-)
If you have purchased the current converter in an online, then you can easily return the part again.

Antwort von Damien:
I have to buy at a store, but with the vignetting is not struck me, because the display does not show the actual picture ... habs only s.PC noticed.
When I hold the lens without an adapter ring for the lens, we see no vignetting, even with adapter ring ... only one synonymous with adapter ring does not see, so it is probably s.dem distance of the lens to lens ... da gibts perhaps other adapter rings ?
Thanks!

Antwort von Jan:
Vignetting You can losbekommen synonymous with stopping down.
If possible, simply change the aperture of eg 2.8 to 5.6 or 8

In many MF lenses can be seen in vignettes to Overscanbereich. Do you consider s.Television the recordings, however, these borders are not visible.
Times by the way: The borders are often marred all sorts of problems. But who cares when you can not see the s.Television?

Antwort von Markus:
Yes, exposure controls the aperture, but in the case described may be coupled with the signal amplification (gain) and possibly even with the exposure time (shutter speed).
Or, the designers have thought about, they would moviemakers with point numbers overwhelm the scale and simplified? ;-)

Aslo the exposure time is not changed thereby, gain can be good ...
Which cams are the way to 1500 euro good for wide angle?
Antwort von Markus:
I would say that any camcorder up to ¬ 1,500 is good for a WW-converter.
Conversely, a shoe will come of it: Which MF lens to 1,500 ¬ fit my camcorder? ;-)
Antwort von Damien:
if I bought an objective would be no vignetting?
Antwort von Jan:
Hello you,
it's just there are some generally well Kanidaten the vignettes are (extreme wide Anglefast all - the Tele really little, if not.)
Also many false purchased adapter ring can alter the beam path so far, are the vignettes that follow.
Whether any camera) is like eg for exposure only strengthened (Gain the question.
Many a bargain has s.Verschlusszeiten eg only one Festblende and a limited range. But in a test we would have to see how the movements change in exposure or not.

So it may be that another adapter rings better than the enclosed?

... I understand what you say nich ...???
this means that any other adapter may cause no vignetting?
Antwort von Jan:
Hello Damien,
Now it gets complicated. If the beam is changed (light supply to the lens), can Vignetierung be possible. Can be very good if you compare s.Rande the finger of the lens moves, and to darken the edge region, because then you just are altering the optical path.
One must pay attention to many things since, eg, some hoods synonymous to a particular focal area. If I take a lens aperture of 35mm-105mm (example) and turn at 28 mm I have just clipped the line of light because the Wide Anglebei 28 is greater than was 35 That means the light does not come so designed as to the CCD.
Similarly, I can not combine any number of adapter on the camera, because then möglichweise can happen the same problem.
Unfortunately there are times now because of your big fish eyes wide Vignettierkanidaten's.

this means that any other adapter may cause no vignetting? Yess Söhren.
Not every adapter is suitable for each camera, even if the connecting thread fit together. It is best if you can try the camera with adapter. Thus one can exclude that protrude into the later parts of the adapter housing picture that the picture quality is not convincing and that the adapter is not fully durchzoombar.
Good luck
