The green apear when I zoom in,

I just want your thoughts about it


By the way, who can recommend me a good Mic to replace the orignal microphone on my Gy-hm 700

Thanks a lot

Mike

Looks to me like the white shading is off. The green seems to be right across the top and appears to be more apparent by the bright light back ground.

I'm only a newby but have you balanced the shading?

Steve

I did the white balance

the white shading is setup on preset mode

so what can I do?

You can set the white shading!
And make another test, to see the difference.

I have seen that with my HM100 when there is a bright light just past the edge of the image.

I actually have seen it on a few cameras over the years when there is a bright light just past the edge of the image.

Hi Eric :-)

I did just now and it's not better

Just did this 2 shots

thanks

It was the fujinon lens mine was the 17-1 lens
I now have the canon I and have no problems. Its the coatings on the fujinon lens and the green you are seeing is the light coming into the lens is flaring and causing a lens flair.
You can try to minimize this by reducing the flair with a card or for instance try putting you hand while this is happening on the top near the lens shade and see if that helps. All lenses can exibit flair . My lighting guy is always setting up filters in the studio to reduce flair from the lights . The canon lenses seem to be alittle better maybe more coatings ?

Thanks Doug

but I have the canon, so the problem is coming from the lens or the camera ?

I just bought this camera almost 2 weeks ago,

:-(

Do work on your lens with a filter to protect the lens, this could be another point for the greenish light.

I have a 82 mm UV filter to protect my lens , with or without same thing :-(

I see in some tests that lens protection-filters can
cause color-effects, mirroreffects and something else,
also the CAs will be more visible with many UV-protection filters,
because the problem is the multilaxer-coating which
causes reflections.

Viewing the last pic img136 it really looks like the reflection of a window just above the frame. I can see dark divisions in the green - like from the vertical parts of a window-frame.

If so the light is bouncing from either a filter on the front of the lens or somewhere inside the camera like from the sensor or the area above/(actually below in this case as the reflection is at the top) back onto the rear of the lens.

Have you tried flagging the lens on top - you could try a piece of card or black-wrap. If it works the answer would to stop that light from getting to the lens - a flarebuster or mattebox/shade with a french flag like the Genus and/or rectangular matte or "eyebrows" at the front of the lens like Vocas and others.

The rubber hoods that come with a lens really don't do a lot to shield the lens at all.

Hi
I tried witout Uv filter and still the same,
I tried to flag with my hand in the top lens hood and the green light disapear.
So this is the problem, but I don't think it's normal at all,
I never encounter this problem with my canon XL2.
I try to contact my local dealer to do me an exchange

but what do you think the green light come from the lens or the camera ?

Which lens is this Mike?

Hi Tim

I have the canon 14x

A shoot tonight, reset the camera once again , take off the UV filter

My garden shoot, Still the same probem it's start to make me very sick and begin to be in

the bad moudy :-(

Hi guys

You know than I have problem with some green halo (http://www.dvinfo.net/conf/jvc-gy-hm-series-camera-systems/289294-green-halo-zoom-gy-hm700.html)

I called JVC pro France today and they told me than I am the first to have this problem, I sent still capture and clip to them.

He told me that is weird, he will try to reproduce this problem, tell JVC to investigate too.

But if the owners of GY-HM700 with canon 14X can try to reproduce this clip and sent to me or upload I will very appreciate.

RapidShare: 1-CLICK Web hosting - Easy Filehosting (http://rapidshare.com/files/268866457/Green_august__18_PAL.m2t)

The green halo came with the high light

thanks a lot to everyone !!!!


Mike

I returned the camera and got a new one from JVC , so just tell them you want a new one period!

Doug

JVC SAID

There is nothing wrong with both lens or camera. It is same with those I have in stock. I have tried 2 other cameras and lenses.
The green light is flare from the lens. It came from the external light source (from windows). You need to use a proper mattebox or cutter or french-flag to cut the light or use filter e.g. Polariser or ND filter. You cannot compare with XL series camera as they use different focal length, angle and different lens element/coating.



they can't be serious ???

Very strange indeed

I sent back today my Gy-hm700 with the canon 14x to my dealer in UK

It's not normal than I have green flare on Highlight even on the church ( RapidShare: 1-CLICK Web hosting - Easy Filehosting (http://rapidshare.com/files/268402218/green_2.m2t) )

Nobody have Big flare like me, same thing in Full Auto mode .

So I will wait to my Dealer change the Zoom or the camera, I think than it should be the zoom, JVC france wasn't unable to reproduce the green halo like me.

I will let you know guys when I will receive my Gy-hm 700 working like yours !!!!!!

Mike

Nigel Cooper reviewed this camera in the current issue of DV User, but it isn't on-line yet. He mentioned a green flare problem with the sample he tested. I'll did it out and re-read it!

[QUOTE=Mike Laisney;1234675]there is some picts about this Problem, I don't know what to do now :-(
/QUOTE]

I don't have the ability to download your footage now, as I am traveling, but from posted pictures looks like you have faulty CCD block.

Which lens is this Mike?
I don't think it's a lens issue, but CCD block is faulty. Ghosting appears in all the frame grabs

Looks an AWFUL lot like lens flare AND colour shading to me. I think Les is certainly giving good advice here.

Shaun, with all due respect have you ever had a CCD unglue or shift? I had this happen. There are always 3 lines on borders of light and dark- not 5 or 7, always 3.

Robert Said: I don't have the ability to download your footage now, as I am traveling, but from posted pictures looks like you have faulty CCD block.

another thing it's happens between a zoom range (15 to 62)

My dealer told me than maybe it's should sent the zoom to JVC singapor fot test and also all unit from his sellers is making green ( weird you don't have this problem ), who knows if it's the camera or the zoom ! anyway has a customer I just want a replacement shortly ( I have this camera from 2 weeks ).

I don't have time to wait after dealer or sellers test, I bougth a new product it should work properly period !!!! what do you think ?

Now I need to rent a camera for a reportage on august 25 ( I sold my XL2)


Hi Robert

I upload the video to youtube, so you can have a look here

YouTube - green 4 (http://www.youtube.com/watch?v=EactSyD1_Dk)

YouTube - green 2 (http://www.youtube.com/watch?v=cVbA3WpZAAk)

Mike, this is what I would do. First of all to test if it's lens, just change the lens and try another one. I bet the problem will appear again with a different lens as well, as it looks like it's a CCD issue. Diagnostic for the camera would cost about 100USD, I can't imagine it would cost much more in Europe. Bring the camera not to your dealer, but to a authorized repair shop and have them run computer diagnostic. I agree, this camera is not working properly, but JVC is notorious for bad customer service and they will most likely try to give you a shaft. The whole advice about the need to get matte box is simply nonsense. After spending 7K on a camera it should work better then this.

Thanks Robert

I totally agree it make non sens at all

I already sent to my dealer so now, I asked him to make me an exchange , so I will wait for

that ( not to long).

A 7000 € will work properly without spending 1000 € for a mattebox !!!!!

Shaun, with all due respect have you ever had a CCD unglue or shift?

No, but I DO believe in Ockham's Razor. Each of the posted stills appears to have the lens pointed directly at a light source and no camera I've ever had the opportunity to use handles this well ESPECIALLY when light is allowed to enter the lens at an angle that would allow refraction within the lens itself.

If upon receiving the new camera Mike has substantially different results, I will defer to the opinions given here but I PERSONALLY believe that issue is more about light entry into the lens and colour shading than mechanical failure.

Ok Shaun

but inside the church how do you explain the light coming true the lens ?

My dealer said JVC singapor have green with all camera and lens... strange again ...

Why JVC France and JVC USA can't reproduce it ?

Why the Gy-hm700 owner's don't have this problem ?

I understand the light coming true the lens, But did you see see how much it turn green !

(have a look on youtube )

it's nasty and not normal for à 7K camera, I tried all diferent white shading setting nothing

change.

Thanks to help me out Shaun :-)

I made some test, during a Image-shot today in Munich. The green-light comes from extreme-white-light (not only direct sunlight), when you take a greater sun-shade you have no green-hallows. In my opinion you must claim the optic btw the coating is green and that can be the problem, when you work with a greater sun-shade it will be all good.
I take my hand to play sunshade and its ok.

Hi Mike,
here is the file.

Eric

My dealer tried with fujinon and Have the same probleme

Camera will be test today by JVC UK

See message below

" JVC UK say they have never seen anything like it and ... blame the Canon lens. Man said he tried Fuji so they
said bring it Wednesday to JVC UK for checking."

he also said the other HM700 makes some blue colour in the same conditions - but not as much

Mike

Ok

Like I said I will told you an update of green Halo case ;-(

SO, JVC UK and Japan think that it would be a CCD issue,

Anyway my dealer send me a new unit and with the same light and shade situation, Miracle

no more green !!!! ok some flare with highlight but no like before.

I received the new unit Friday morning, in the afternoon my viewfinder shut down, guess

what ? it's dead !!!! No lucky at all ..


I received this morning a new viewfinder and so far everything is working ( croos my finger )

JVC need to give me a purple heart medal !!!!! :-) I deserve it !!!

4 years with canon XL2 never have any problem, perhaps I love the HM 700.


Mike

Ok
SO, JVC UK and Japan think that it would be a CCD issue,
Mike

Mike, I am glad you have this issue resolved. I am also glad you did stick by your guns and did not cave to bogus theories about need for matte box and such nonsense. From the frame grabs you posted it was quite obvious it was a processor or CCD issue.

No, but I DO believe in Ockham's Razor. Each of the posted stills appears to have the lens pointed directly at a light source and no camera I've ever had the opportunity to use handles this well ESPECIALLY when light is allowed to enter the lens at an angle that would allow refraction within the lens itself.

If upon receiving the new camera Mike has substantially different results, I will defer to the opinions given here but I PERSONALLY believe that issue is more about light entry into the lens and colour shading than mechanical failure.

BTW Shaun- did you change your mind then?

I read something that the companies works with different lesns coatings,
Fujinon with blue-coating und Canon with green-coating,
that's the result for this green-halo-effect.

Most of my shooting is live sports, and the biggest problem I have right now with the lengthening evenings is the green glow from the sun and floodlights. I changed my white-balance for the last game I filmed over to 4300K, and even though carefully looking for it, saw no evidence in my footage. Now, saying that, the place I was filming from doesn't have the brightest of floodlights and the sun was behind me, but any mitigation of this issue is great to have.

Hi James

I had to admit that I came very close to purchasing the HM-700.

I have taken the plunge and bought a Panny HPX 300.

I have looked at every cam on the market around $10000 Australian for around 2 years now.

I have owned and was disappointed in a EX3, studied the HM 700, Panny hvx 200 - 171 etc, waited for NAB '10 and hoping like hell Canon would come up with something spectacular.

Why doesn't someone build a:

3 x 1/2 CCD
SDHC recording format
AVC intra 100
Interchangable lens format
HD SDI / HDMI interface
Shoulder mount cam

If they did, I am sure they would have real success.

I am hoping I can learn my new cam inside out to take advantage of it's plus's and minus's.

Good luck with yours.

Michael
