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 !!!!!

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.

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

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, 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.

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.

James McBoyle May 14th, 2010 07:00 AM

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
