I have some questions s.alle times with a 35mm her own name or have a built themselves. I have also built myself and am with the results so far more than satisfied. As for me s.meinem Picture stört previously, the Vigniettierung s.den edges. I wonder whether the more expensive adapters purchasable also vignetting occurs? Lenses I use the old Canon SLR camera. (50mm / 1.4f), (24mm 2.8f) and (90-230mm / 4.5f). The 50mm lens provides the best picture results. The 90-230mm lens is a little dark, but with sufficient lighting, but still OK. The 24mm lens is much worse because it creates a stronger Vigniettierung. Why? The reflex camera, in all 3 Lenses were used, this is not the case here. Now my question. Is there any possibility that Vigniettirung completely avoid? Or is it only used s.den lens reflex, or even s.der macro lens? I can imagine that I am with a macro lens, with an even stronger magnification Zoom out the Vigniettirung could. That would have to follow that I have the Wide Angle would decrease further. I've uploaded some pictures.
Ah yes, the used camera is a SonyFX1. Here you can get the first test shots with the look. The dark edge of the left Page s.der been fixed.
I hope someone can me any advice because of the problem Vignittierungs say.
Edit:
When I look at the SLR Lenses s.der use, they are exactly as wide as in the pictures with the. Picture of the cuts in fact only in the Height, in order to come to 16:9. Where is the difference between Camera and. The distance between the lens and screen are identical to my camera. Thank you very much Regards

WW optics tend.
Distance from the sensor / film is mostly the reason - is called a synonymous Auflagemass

How to fix it I can not say sorry. Think through adapter rings maybe.

@ Serpenteye
Could it be that you have to provide the most impressive depths (un) schärfe to receive with open aperture s.Lens before your work, the Still Image Camera Aperture you but according to your film speed closes? What light conditions prevail s.Deiner projection screen and the film surface s.der or s.der sensor surface of your camera?
3 Apertures difference and there is hardly more of a perceptible vignetting ... The curse that is often the impenetrability of the light projection surface and the urge to unprecedented depths (un) focus to achieve ... then this is a possible outcome. Unfortunately, you have somewhat to say the lenses, but nothing about the parameters that are conducive vignetting.

The vignette, which is a waste s.den brightness edges shows, especially by a factor influenced by the screen. If you are an experienced hobbyist, you will have found out that the light loss through the screen as low as possible must be kept. Before ordinary copy paper forms a lens almost exclusively from a circle, in sandwich paper has the whole picture, but with a strong hotspot. With time, there were technical improvements s.den adapters with milled glass, which was rotated (DIY Instructions "CD-dummy"), then vibrated ( "razor-engine") and more recently with eccentric rotation and special touches, the s . the edges less light swallows. The effort, which is operated in order to avoid the sticker shows: it is typically operating principle (if synonymous with good purchase adapters only with apertures smaller than F5.6, f8 eg, visible, more recently, supposedly no longer).
For WW is a typical vignette blur, and only by respecting the causes to prevent the I that
Antwort von serpenteye:
Thank you for your answers. I call myself not as an experienced farmer adapter, quite the contrary, it is my first. I maintain only of me that I have good technical skills. Basically, I have the SLR camera which I copied into the distance of lens to screen the film or did. The distance of the camera screen, I have determined through testing, which is far the best results. Through a screen, which s.Rand more light pass than in the middle, I have been synonymous drüber thought. But you kswo something herbekommt.
@ WoWu:
Yes, the Aperture of Lenses is quite open and I regulates the brightness with the aperture of the camera. What brightness on the screen is, I can not say. Your statement, "3 Apertures difference and there is hardly more of a perceptible vignetting ..." I can not quite follow. What do you mean? Should I use the Aperture s.Lens close and open the s.der Camera? I have honestly not even thought off. Unfortunately, there is a problem because Chen. The Canon Lens Bionett I have also built themselves. Unfortunately, I can not handle the small aperture s.Lens control, so the lens aperture always fully open. Let's see how I can fix this.
Once I had improved a bit, I will report them.
Until then.

Times I would not generally work with a zoom lens, but what you did here. The vignetting always been synonymous of house from more than fixed focal lengths.
But times ne legitimate question: There is good new for 1000 EUR, for example, Letus, there is scrap from India for 300 EUR, with security not worse than you. Why do you care?

One difference between the 50mm and 290mm, the Vignittierung not watch. Only and alone is the Picture of the zoom lens darker. The 24mm was not to use the Vigniettierung was too strong, the scenes I have to complete the video is not used. I can not say exactly which scene with what was Lens. But it was roughly 50:50.
In this paper, I just need to find out if there is a possibility the next Vigniettierung reduced. Unfortunately, this with the opportunities that are available to me do not go. However, I am with the result more than satisfied.
Antwort von WoWu:
Of course there is a possibility: smaller apertures s.ersten Lens!

Naja ich würd mal is synonymous with nem nd filter before optik try. matte box and filter holder should be at each DOF adapter accessories compulsorily be! order can then open up the aperture so as it suits you - but one outshines s.der screen image is not good;)

And it works just .... not! ND is exactly what he is not needed. He must change the course of radiation to a uniform (right) illumination to get.
Antwort von Kabelträger:
I admit to something s.der solution of the problem to have shot past ..... Well but the synonymous Aperture zuzumachen can not solve the problem! Man loses at DOF adapters always enough light anyway.

Antwort von WoWu:
Yes, Flo, of course you have right to do so .... not all tingly. So yes, these are not really synonymous the yellow from the egg .... and certainly not the self-constructions. He may, of course, synonymous a telecentric lens screw it ... but then the cost of a multiple lens camera all its equipment.

Yes I would prefer the focal with the camera to play to a reasonable depth of focus to achieve ... since then synonymous with your proposal to the ND well and quickly probably helps a good result. However, he will not screen this effect, which is often synonymous want is ... Now that's drum, we can not do more than make suggestions on how to prevent vignetting effect.

I am once again exactly the Vigniettierungsproblem addressed. I have the SLR nachgemessen and extent of the lens to film on my (Lens to screen) transferred. The dimensions agree exactly agree (4.2 mm). With the macro lens, I can just the surface of a 35mm film abfilmen sharp. I put myself the question why the SLR Vigniettierung not occur but on my screen.
I'm already gone so far as that I am an old Mattscheibe s.die position of the film in the camera was installed. Also there was no Vigniettierung to see.
Then I noticed by chance where the Vigniettierungsproblem came could. I had my FX1 with aufgeschraubter macro lens against a white wall. Since the zebra-peak was turned, I saw on the display a circular pedestrian area, s.Rand of the display image was not a zebra can be seen. This I agree that the macro lens Vigniette generated by s.Rand less light through.
Now it's 2:00 at night. Be it tomorrow during daylight hours once again to investigate.
Good night

It is said that it was pointless to even tinker with. These experiments are, however, to one, if you possibly synonymous with a land purchase adapter, deeper into the matter lead, as it mere theory ever could. Well, buy adapters have a better Nahlinse a Achromats. Something for ¬ 15 of Hama is overseeing the entire row gepappten lenses for color bleeding in anyway with adapters so coveted backlight. They prohibit but apparently synonymous in this already much closer basis.
Antwort von serpenteye:
It seems really s.der macro lens is, or it enhances Vigniettierung at least. I have of always talking of a macro lens, of course, I have a achromat-Nahlinse.
However, I am satisfied with my own. If not so, that I now absolutely everything with the film needs.
I'll time a High Nahlinse test. When do I need to nix brings halt to live.
