Frage von Daniel_23:
Hello!
I just bissel experimenting with the manual mode of my Panasonic NV GS 27 rum. I have the impression that better at high shutter (1/500th of) the quality is. However, my cam there governs the Aperture itself. If I Aperture still governs the shutter will remain the way I've set it.
The aperture of f16 to go to my camera and then f0 of 0dB to 18 dB. If the signal because electronical made brighter?
What is better now, more aperture (opening?) Or slower shutter?

Antwort von PowerMac:
Your Aperture is not sure of F0-F16;)
There are allegedly F1.8-3.8!
Antwort von Fan29:
F0-F16 will likely appear in the camera is so synonymous with my Panasonic. That they will just have to convert somehow.

S.alle Hello!
I'm interested in this topic synonymous burning! The following posting was of me:

Unfortunately, however, that no reaction!
I hereby ask you again for info!
Thank you very much!

@ Toni - more professional video in such subjects I know nothing more better in the photo area, where you stay closer to 1 / 125 sec - 1 / 250 sec, more than 1 / 500 you would only see little of your Dynamics Sprinter, all synonymous a question of the prevailing light to try it, you really have to own - test of where the sprinters Page / come forward, AF usually prefers to - not when vorallen SonyCam. We'll see if one of the professional videographers Slash still reported.
The GS 27 has already aperture of 1.8 to 22 I think warns'in the known steps 6-8. At the GS 27, the aperture can not be changed when little light is available and or the shutter speed and is already at 1 / 500 or 1 / 250.
The GS 27 is the Aperture will always be open at least a little room for a good picture to have to close the aperture then to 22 would have to be fatal, but can still be strengthened - with, unfortunately, more noise - but often quite useful to to see at all except what a black picture.
For professional models but can still be changed at any time the aperture, the consumer area, in Pana is at a high speed / low light - usually only the gain or adjustable - just open Aperture 1.8.
With better lighting and a moderate shutter speed but I was already synonymous Aperture and shutter manual free to choose.
In the small 1 / 6 "CCD brings the aperture will change by less depth of field, but very difficult to conclude s.Besten yet complete then go into the telecommunications sector is smaller than the depth at wide angle.
The GS was 27, I think exactly synonymous describes when and at what a setting is locked, ne time ago when I read the GS 27 Instructions.
Reinforcement brings more noise and would probably only in the case of really lousy lighting results are applied - to get as good a picture as possible - I had yesterday synonymous with Pana GS 500 with 12 DB increase - without the LCD was almost black - 0 Lux program, I would not take - if there's nothing more moving, in spite of severe Aperture synonymous smaller depth should still be raised to 5.6 or 8, as with open aperture (1.8 for you so) pretty much every lens does not deliver optimal results.
The great strength of a lens you can see how good it is with Aperture open, stopping down to 5.6 or 8 machts rauszuholen the lens easier to everything.
Yes Fan29 digicam's synonymous only go up about 7 what Aperture will probably correspond to about 22, at Pana but are really the converted screens already stated.

Antwort von Daniel_23:
So at the GS 27 can change the aperture always (except when the color night mode s.ist, but good for nothing anyway). Whether it's dark, light, the shutter is fast or slow. Even when fully make 1 / 8000 kanns tdu the aperture.
What is nciht sit ne certain Aperture Setting and then vary the shutter. Versa gehts (certain) and then change the shutter blende.

So conversions or equivalents or equivalents of Aperture ads with camcorders in Comparison to Small cameras as discussed in January there are not or are not necessary. These relative aperture values are already real
However, we can not display the shutter still compare with those of KB-mount lenses, because the absolute aperture in millimeters at a small recording formats (eg 1 / 3 inch) synonymous correspondingly smaller than that of KB and a fortiori as for medium format cameras, and only the depth of this absolute aperture is determined. Thus, a small video camera so its inclusion is a fundamentally greater depth than chips such as a KB with hat-camera at the same relative aperture.
For small apertures, another absolute physical Phännnomen comes into play, namely the diffraction of light around sharp edges. This leads to image degradation and gets worse the smaller the aperture is absolute and depends only of this down, because the wavelength of light, so synonymous is an absolute size.
It is not true that whenever the best image quality with video cameras darkened lenses, but on the contrary it is getting worse.
This is synonymous for the reason why not many camcorders in Atomatic mode, an aperture admitted as much above 5.6 and would rather better internal neutral density filter is used.
Conclusion: Aperture manual rather be fairly open and with the exposure times did not go much below 1 / 100, otherwise the picture stutters quite beautiful because of the lack of motion blur. Density filter to regulate the rest
Antwort von Jan:
I thought digicam / Videcam are more equal, Small.
In digicam was 6-7 with Aperture, I think read somewhere that roughly corresponds to 22 at a 1 / 3 "or 1 / 2, 5" CCD.
But not synonymous with open aperture of the optics with a video camera s.Besten, best results are obtained with light fading out, I do not mean to 22 had deliberately called 5.6, then nagut 3.6 or the value of the Cam arbitrary Cam exactly. Stand in photography so if you mean that when fully open aperture, the best results are achieved, then ......

Antwort von domain:
Well based on the absolute aperture could even vote this conversion, but what does it?
Incidentally, the photo-and micro Minox spy camera had no aperture, but only neutral density filter, the main focus, they also arrived with an open aperture. The same applies to synonymous Lenses in the various flat panel scanners, synonymous with those already reached its full open aperture sharpness. In more modern camcorders is built around the aperture level, a gray grad filter with which the majority of the exposure is controlled, and so it comes off of small aperture values. In general, it is not advisable at all of manual exposure. Apart from exceptional circumstances (backlight, front light, snow reached, etc.) is in automatic mode, and the fact the optimum is especially true for beginners in the video sector. Ev, the maximum exposure time nor manual to 1 / 100, or if necessary to put on 1 / 25, but allow at least the aperture and Graufilterautomatik. The Zebra Function Beginners synonymous helps a little, because there must be no slack motives Zebra and high-contrast images are underexposed with overall security, if that was not seen in the viewfinder zebra.

Screens can be useful-and used Shutteränderungen only if one has previously made a series of tests and has studied dei results on a display unit. I was always a Stillimage / video laptops in the results of tests are listed. Then I usually know fairly well what awaits me in this or that attitude.
Antwort von Jan:
Yes interesting, but I have learned in the shop 13 years ago, a high contrast lens gets the best - most brilliant Picture
not to open up Aperture. This is so synonymous with intense Lens Tests tens's of magazines ala Color Stillimage / or photo magazine said, distortion and vignetting can be synonymous with Ablenden improved.
There are active, eg a F 1.0 fixed focal length of Canon (EF 1.0 / 50 USM not really) more likely to imagine 1,01,2,3,4 ... Companies that manage this comes out when the incident light back in equal measure - this is almost impossible to open Aperture, it's like an absolute blur, Tester said in Aperture 8 can speak to a man of sscharfen / good picture.
The Photo Tray is where video can be a bit different.
Color Stillimage once had some digital cameras at about 1 / 2, 5 "CCD with a diaphragm test in the same issue, I think it came out so there's at f5.6 the best results, extremely deteriorated but synonymous stopping the Picture - since you have law.
The profihafteren I have no experience with the appropriate shutter speed for video, I had added up, well that you have reported you.

Antwort von Jan:
Hello,
so the information of our "guests" meet the consumer video models, or it will be done.
One can easily test it right what a cam adjusts the automatic,
at Panasonic s.GS 180, at Sonyab HC 39 / 42 / 44 / 46 and at Canon s.MVX 4i / 45i can be the exact exposure time for the scene show - MVX 40 I could not test, but I think even synonymous.
You get the used shutter speed / aperture / gain on the LCD display during playback. Guterweise all known companies may take 3 exposure values recorded at the time of the competition synonymous show, sometimes not everything.
For the user this is interesting:
Canon displays of Sony / Panasonic no amplification,
Sonyzeigt no shutter speed of at Canon.
All other values are shown of Allen.
There you can really see working synonymous with slightly worse lighting conditions, all 3 companies with a way to reinforce the 3, 6 DB.
Aperture is almost always open - exactly as described host (it has 1.6 - 1.8) or f 2.4, except under very good lighting conditions with the best of the sunshine, then there's the exposure values as 1 / 250 s with Aperture 11 / 16, 1 / 500 or faster, but of the camera is a hardly ever alone.
In lowlight is usually 1 / 50 or less 1 / 100 sec with an open aperture with high gain 16-22 DB used for consumers of all 3.
So synonymous Canon and Sonyverwenden strengthening even at the 300 ¬ cameras independently.
With Cam's higher category, out of the professional segment, with large sensors, but I think that Aperture is not always open.
As I said at Digiknippsen is supposed to be a value of f 3,4-5,6 so get the best results for the lens.

Antwort von prem:
It's been so that higher-synonymous-grade camcorders do not provide visibly better performance on edge dimming.
If one example. well with the VX2000, which is already good and sharp at open aperture and is not synonymous much better when stopping down.
The generally verbereiteten knowledge to improve sharpness in Small-and medium-sized digicam with dimming can forget the rather short focal lengths in Konsumercamcorderbereich.
Antwort von Jan:
Ah, now I have randomly again the report of an experienced / well-known cinematographer's cinematographer from the newspaper, the time just as I have already learned it is not synonymous with open aperture.

Antwort von PowerMac:
That is so. Open Aperture in bad Lens = generally low severity. I know that even very good (or bad) of the FX1. With open aperture, the picture is really nasty soft and no longer sharp. Nothing more HD.
Antwort von Schleichmichel:
One might even add that excessive stopping down does not necessarily produces a sharper picture. The light rays bend then s.der edge of the aperture.
@ Jan: The Aaton XTR series is a very good and popular alternative to SR series of Arri. It is (as with all AATON) very comfortable on the shoulder, is well designed, easy to use and purrs softly.
