Frage von HVR1000P:


Hi, I own a JVC cam with a Fujinon TV Lens. When I ring the sharpness s.den attack turn towards infinity, the picture is slightly blurred when zooming, focus point in the distance shortly before the attack, is it normal or a case for the service?

Antwort von r.p.television:

If you have the HD100 and HD200 from the professional HDV series do:
It is with this lens, unfortunately, normal and not just for this reason the lens is known as a fragment. Skewed continuous zoom and other unacceptable defects make it far worse than any festival in Consumercamcordern optics.

Antwort von HVR1000P:

Nee, I meinet actually a A15x8BEVM with 2 / 3 "Adapters to 1 / 2" s.einer GY-DV 500th

But what you write is ineressant, because I consider a move HD200 251 ...

Antwort von r.p.television:

With a 2 / 3 "Lens to me this lack funny. As I would of an adjustment, etc. are talking about.
However, the adaptation of a 2 / 3 "Adapters s.eine Optics using 1 / 2" Camera is anything but ideal. Besides the focal length extension there are other disturbing influences, with which I could not live. But the mere fact that you have an expensive Wide Anglebenötigt to approximately normal focal length to approximately 45-50mm focal KB to achieve is very irrational.

PS: JVC has with the 500 one for their exceptionally good relations Camera on the market. Do not be tempted to transfer your experience and the HDV Series. As I would for many reasons the hands of leave. Not only the lens is scrap (obowhl reason to buy as often stated), but the Camera fabricates synonymous in many situations where other bad images make good cameras. Also, the processing is bad. Often interrupts the Viewfinder s.etc.

Times like this I went from the thread starter that knows how to Auflagemaß recruits. There is actually a non Lenses deducible Back Focus have - but usually only in the fall of HD cameras and not with a DV Camera.
The Lens of the HD100 for example is located in Unendlichbereich next to the attack, not as it should. I thought he wanted it out.

Otherwise, of course, a good throw-in times where laaaaange Rookies cameras have no wish to be able to use it ;-)

@ HVR1000P
Hello Mike.

The observed effect of your lens is at the lower and middle synonymous nor the normal price range.
The phenomenon is with the quality of Lenses in general rapidly, because that is s.den refraction values of the different glass types and the curvatures because the Bikonvexlinsen, the beam deflection for the focus of a package already s.der first lens and good lens Lenses have forms, for where the crushing forces of different radii evenly distributed.
The industry always moves back to that end axis rays only meet at infinity, so somewhere in the universe.
From theory yes synonymous correct, only not helping the cameraman.
The Lenses of this effect we show (usually the bottom and yet the average price segment) all have a mechanical stop feinjustierbaren get .... Then again synonymous infinity is sharp and not somewhere in outer space.
And the cutting-wide setting works again synonymous for ww and teleport.

Just a word in addition to what has already rptelevision.
If you are mechanically 2 / 3 to 1 / 2 adaptierst, you have about the image circle effects synonymous nor the problem that the lens against the lens apex edge has a different relationship than in a corresponding 1 / 2 "Optics, so in this case the mechanical and the optical Auflagemass too far apart. blurs the edges are the result.
So prefer a suitable Optics as a supposedly "good" 2 / 3, on a 2 / 3 sensor certainly has good pictures on 1 / 2 "are identical results but can not be achieved.
In addition, the resolution values (MTF) lower than a 1 / 2 "Optics and generate inferior images on this sensor.
So my advice: Finger weg of mechanical adaptations.

Hello Wolfgang,

Would you possibly synonymous ne number, what the price range is concerned?

Antwort von WoWu:

Hello Dithelm,

Robbie has already written the x17er series of Fuji, but synonymous, the x-16er series of Canon is already quite good optics, but also synonymous its price.
In the case of optics above ¬ 16k usually synonymous use other sorts of glass, where the varieties in alternating bonding and so have different refractive indices.

But when your Lens synonymous yes you can attack a small build so that, at least, is the unspeakable "infinity problem solved.
That is just stupid, that such problems have become more noticeable, the higher the Resolutionist.
The correction of the CA, for example, is a product of the U-HD Endwicklung because CA in such Resolutions course is fatal.

Thanks for the reply,
na ja's fit then yes, that I yesterday a huge money was a gift because I'm really satisfied with the standard lens does not. ;-)

Antwort von HVR1000P:

Nu is the thread starter again as synonymous ...

Basically I have with the GY-DV 500 and dem2 / 3 "not of Wolfgang problems, produce synonymous but not for TV, film industry exclusively on DVD. Vorbesitzter of the Cam, however, has worked for ZDF. The only deficiency is in fact the small "infinite-problem", which is not extremely disturbed. Comparison of PD 170, the images seem better.

A bigger problem is actually that more and more 16:9 is required.
Since the filming work is often very long and are rarely a tripod is possible, I am on a (real) shoulder mounted camcorder dependent (which is not long and large to be ;-)). Who 8h times with the Henkelmann has worked knows what I mean.

The idea was now a JVC HD 200 251 to purchase, and my next lens to use. Even if it is not perfect. But for this lens, I have lots of accessories. Here the question:
Could an HD 200 with the 2 / 3 "Lens work better than the originals with Lens. (As I said: no TV)
Den when I 9000.00 Lens for an issue should I switch directly to SonyS270.

It greets

The Mike

Mind! (I was about 1 / 3 inches is not so clear ...) JVC has actually an action with a free test run, the camera will extensively test times.

Antwort von WoWu:

@ Mike

Glaub'mir, it looks really not good, because the 2 / 3 "... and add SD Lenses are really synonymous designed for SD.
The difference in the MTF, you'll immediately see, because in the course of HD lenses goes to 30 MHz, whereas the SD Lenses very aware (from Alaising reasons) immediately after 5 MHz drastically drop.
You will be in comparison, even with the supplied Fuji Lens x14 this drop see clearly.
Otherwise, the HD 100 (200) from her camera head and a beautiful part of the Fuji lens is the head simply not fair.

@ Diethelm

Does the 200 really a firmware update to that now offered 1080i ... not that I find it interesting ... who 1080i/25 - 720p50 prefer white, I do not believe what he's doing, but I would be interested to know whether this JVC as a committed customer service.
Even Robbie setting SonyJVC preferable, as synonymous, I can not understand, just think s.die times unspeakable weakness he EX1 and the lens, while on the Zeiss, is ultimately synonymous of Fuji built.

Antwort von Natevi:

I do not know, a month ago I had the latest box s.der.
But I have no more synonymous in demand, because now I've found a workflow, as I have with the missing zurechtkomme seconds, without the amenities, such as automatic Cliperkennung and TC in Final Cut Pro to renounce; 1080 and i wish I did not .
This box is quite in order and provides particularly good at moving objects, pictures, what happened to me in my projects is important. The handling is definitely good, it is thick with the Battery fed on the shoulder and can be wonderfully ergonomic needs. Also use it in tight spaces, on shaky scaffolding and narrow passageways in factory halls. And they seem synonymous what abzukönnen. Have recently been more than four hours in a very hot environment with 100% humidity filming them. No Drop-Outs, nix.
Conclusion, with all the teething problems I had, which I occasionally s.der accuracy could doubt my decision, I have faults with the part. The camera work s.sich is definitely OK.
Was it now a little bit off-topic, but I think that it could be interested

Antwort von Natevi:

The JVC 100 - yes 200 is now the TH 16 x 5.5 BRMU supplied, it was always here? Or is there something being done?

Antwort von WoWu:

Jau, das war es ... Good x-16er series of Canon is synonymous. Fuji is in the x-17er (or more)
Although it is a naturally synonymous succeed, with the 16er sensible to make pictures, you can just leave and not 5.6 zoom and a focal select the values at the halfway reasonable.
Then see the images synonymous good. But whether this is the point?
It really is slightly unfortunate that the head is not some halfway sensible Lenses exist. And we have seen in the other cameras synonymous not forget that the quality of the image is often synonymous with the entire framework of funding is kept at bay, because the pure Lenses another Pro-Sumer kameras synonymous not very likely to be much better. Only the means that you must use manual, are just as Camera of the set, much like a workaround.

Antwort von WoWu:

It is always depends on how much of the "good optics" in reality, according to expected and will be corrected.
Not everything that looks good today is of the Optics. And the CA eg no longer be seen is not a question of good optics.
The fact that CA but again Dynamics appearance and abruptly disappears when focal, is not a flaw, but actually makes such well-intentioned features only hard use. Switched off, it is not at all.
There is enough talk about what has been ... synonymous with the zoom blur transitions, etc. The camera is still not free of weaknesses.
But that is now quite sure ot
