Frage von Kahless:
Hello, dear friends of the video recordings.
I'm of the videography, as synonymous of the photography absolutely no idea hope un that account I have that I can help someone in this forum.
I am planning a Project, which represents is the following:
I want an oject size 55x55cm located at a distance of 100-25m is possible, represent contrasting on an LCD display. So I get a possible contrast Picture, has recommended to me a well-known a black and white camera to use, but I have no idea what digital camera is for or what lens should I Besor for it, or whether it vllt even better is to put a scope in front of the lens. (The white object is to beobachtenede ebenfals black only)
For suggestions, I am eternally grateful.

Prinzpiell are no black and white cameras in today's digital age and even if you were to switch to an electronic b / w-camera, you'd have 50-60 year old dinosaur dig out from the beginning of eletrotechnics tv ...
For your work you need a video camera, the picture can manipulate internal. There are some consumer cameras on the market have built-in Effects. They are then black / white, sepia, etc. Some of these cameras, you can increase the contrast synonymous - if you but a highkey / lowkey want to make history (ie black / white and very few shades of gray in between will) you with the Consumer devices will not be far.
With a camcorder from JVC GY-HD series you can do that, however - only he will rent to buy be unique too expensive, would be fashionable.
Second option would be a perfectly ordinary way, camcorder with Firewire to take forward this on a calculator or notebook can be and with the VLC, the picture show. In VLC you can run it without problems, "bildverändernde" filter - with "levels" should be synonymous pose a high / low-key no problem.

Well this type of targeting does not require S / W-camera, but only one good software for evaluation. Of course after launch must be synonymous, the destruction of the target accurately captured by the software. Some providers, such as EADS and ESG beautiful solutions have to offer.

Just to avoid such comments I have concealed bewust that I am an active shooter and I wanted to facilitate the observation wheel. That account should be synonymous Camera offer a good contrast, I will, after all the holes (again about 5.6mm tall) on the disc (55x55cm).
Namely, I have no desire to crawl after each shot to the spotting scope. The Camera direckt present the disc I can not, unfortunately, because not even a stone may lie in the path (to avoid accidental firing, ricochet).
I shoot only two distances 25m and 100m and is exactly what I wanted to grow a camera for observation. Just because I have absolutely no idea of cameras and lenses, I wanted to be showered with proposals times.
ps I'm used to bad comments about my hobby, this account you probably understand that peddling with the info I will not go.

What did your friend was probably a B / W Viewfinder.
Does your property? - That is, how important is the focussing
Does your object all the time - Picture Screen will be shown fill?

Antwort von Jott:
55x55 cm, 100 yards away? In addition you need quite a Wumme of Tele plus a tripod that holds something synonymous. Without the now calculate, I guess that makes since with the normal selection of camcorder do anything. Rather, with a DSLR plus giant Tele.
Antwort von Kahless:
@ B. DeKid
The disc moves normally an inch (it's a fool because Seih hits the rope)
The object must not all the time are displayed on the Bildscirm, beautiful but it Währe. Wanted a 15 or 17 inch LCD can show.
@ Jott
Therefore I wanted to make me first times clever not think it will s.end exorbitant.
Antwort von Bernd E.:
... 55x55 cm, 100 yards away? In addition you need quite a Wumme of tele ... I guess that makes since with the normal selection of camcorder do anything. Rather, with a DSLR plus giant Tele ... If I have not miscalculated, we could appear with priceless anyway DSLR-optics of the necessary size only to artillery firing ranges ;-)
On the basis of a target size of approximately 56x84cm (55x55cm s.die because your camcorder does not include square), you would need a small picture that is at 100m distance focal length of 4300mm, at 25m distance would suffice just 1100mm.
If there is a useful application for consumer camcorders with huge zoom plus digital zoom, then it might be this. What of such technology is to be kept in the usual video everyday life, we all know, but in order to recognize holes on a target, should meet the image quality. Panasonic, for example, for under 300 ¬ SD camcorder, the optical zoom is in itself almost 2600mm Focal. Perhaps such a device would be suitable?
Antwort von tommyb:
Alternatively, you take a camcorder adapter + + telephoto lenses for DSLR.
Example, there are lens for 1 / 3 "cameras that then create a 7x Focal by Cropfaktor (and then we suddenly 500mm from 3500) ...
Antwort von Somin:
So I know as a shooter and you shoot the Videograph only with small caliber will the distance and therefore would make the camera to the front, on the ground with a metal casing around the outside and good. Then a little bnc cable to get to the shooter and ready.
Antwort von Kahless:
@ Somin Unfortunately we are shooting at us, not only small-bore, therefore, must be of anything found in the weft direction which can lead to ricochet. Thus, the ansich good idea with the camera falls off the plate away, unfortunately, that I would have relieved much synonymous.
@ Bernd E. Well, I do not know if enough of the Focal 2300th After all, I put the picture's only on a 15 inch monitor and since then I have to synonymous still recognize the holes.
@ TommyB Go nuts good. The image quality suffers significantly less?
Antwort von stefanf:
Get yourself a ton of Russians and converter, then ran s.die Cam.
Finished ... Russia has 500 metric ton or 800 mm with 2x converter 1600 and then searched with conversion, I take are sufficient then at 1.6 times certainly.
Antwort von B.DeKid:
What TommyB has been proposed is an example with XL1s Pros EF adapter and the 70-200 mm
The 300 mm fits synonymous s.die just came ..... the 400/500 and 600 does not work anymore because too broad
Whether the 400 Nikkor AIs fit I do not know I still have not tried.
But the prob is that the cam must be installed completely static
But with the 200mm, the size will get covered in about .... I can test times what we see in which I measure with the laser distance meters, the watch and see how much one of a DINA1 cardboard.
The XL1s is not really cheap
A small überwachungscam would be placed directly in front of the disk, I placed my things which are as big as a lighter

Antwort von Somin:
yes or rebuild the stands directly on electronic equipment, the move has made our society precisely. One plant costs about 1500 - 2000, quite a lot cheaper is not the synonymous with the camera.
Antwort von Bernd E.:
... I do not know if enough of the Focal 2300 ... The 2300mm reach the camera alone with the optical zoom digital still turns you to it are downright ludicrous possible enlargements, which naturally decreases the image quality considerably. In the area that is relevant to you, the Picture, however, should still be usable. Moreover, this is only the first Panasonic camera, which I stumbled. There may be additional camcorder of this kind with more optical zoom range.
However, if you can spend considerably more money and the camera does not have to be small, then you will get with the other proposed solutions ensure a better shot.
Antwort von Kahless:
@ B. DeKid If the camera is really not very favorable.
@ The Somin falls flat for us, unfortunately, the plant is outdoors and it still synonymous in a conservation area. Consequently, there is a building ban and we have no connection s.das mains. Because the system of quite far away from civilization is, we can indeed shoot and when what we want, but unfortunately we have always synonymous with the problem of vandalism.
@ Bernd E. Well a heavy suitcase, I did not always carry the state, but I've been trying to reach the optimal Ergebis at minimal cost. When I consider that a good spotting scope will cost around 1000 ¬ and a very good is 2.500 ¬, then I would invest so ¬ 1,500 for the camera, including lenses
Antwort von B.DeKid:
You do not need much money to take in hand
A small Fingercam (monitoring systems) to either via cable or NEM rer 2.4 Channel Receiver Transfer Module and TFT from NEN small car specific
The Cam placing it on the floor (including estimated size Battery and radio or cable box cigarette box.
On ne Monitor Battery (for wireless receiver)
And a small suitcase.
Since there are no synonymous Probs with ricochets or other
You can even place behind s.Stand ne old small video camera between the receiver and monitor and record the data directly.
Everything else is "with cannon shot to crack a nut .... then you can install it directly ne shooting video wall ;-)
We have only spotting scopes s.Start almost synonymous or two video walls (Anlagen.
The Cheyenne is here synonymous to synonymous Grosskalieber at distances of 10-100 m at the location.
Via spotting scope is just acceptable and sufficient because it is a "classifier" and a "shooter" s.Stand are.
That's enough for Trainning. Whether hunting or sport.

As always build ne XL1 is to document only the bullet probably more strange than "".
Especially in the focal length range, the vibration in the vicinity of the state to be enough to distort the picture.
