Sony PMW-EX1-Bildfehler beim Zoomen und Schwenken?

SonyPMW-EX1 image errors when zooming and panning?



Frage von JoHi:
Februar 2008

Have heard that the new SonyPMW-EX1 will be totally useless, because when zooming and panning significant artifacts are visible. Has someone already experience this? Joachim (turn so far with the Z1)



Antwort von Andreas_Kiel:

Hier stehen im Artikel verlinkt zahlreiche Ergebnisse of einem näheren Blick auf diese Camera.



Antwort von Giagl:

a good movie is so much by zoom and pan at the same time ... .. s.besten

So Edelschrott (?)





Antwort von vidwalter:

JoHi
Have you so far with the performance of your Z1 satisfied? If yes, did you synonymous with the EX1 no problems regarding the problem of your target. On the contrary. The mbt Codek 35 is very good and much better than the FX1/Z1 still in use!

Schöne Grüsse



Antwort von Giagl:

keyword rolling shutter ...
believe the choice is rather



Antwort von r.p.television:

During fast panning and zooming, I rather just tumbling lines observed, however, synonymous large artifacts (ie, more image-quarters) in a fast changing light / dark.
The majority of errors produced in the EX1 quickly changing light, for what they are concert recordings of all kinds and makes similar inappropriate.

Since one must simply ask the question whether Sony's decision to put on CMOS, not a handle to the loo was.



Antwort von Manuell:

Hmm.

The problems would then SonyHVR-Z7 but probably synonymous? Would like to see that soon either the PMW EX1 or Z7 HVR pick and would like to film the concerts, they would indeed seem the two are not suitable?

These are, however, alone of the host perspective, and would depend on equal terms with each other Camera synonymous occur.
EDIT: I just came out that you are likely to be the phenomenon of oblique straight lines figure actually mean (Engl. "skew"). That would indeed be a CMOS character.

Antwort von WoWu:

That is not quite true:
That is no problem of CMOS but a problem of a CMOS chip without global shutter to have chosen because it goes very well with CMOS synonymous without artifacts. We should just not use cheap goods.

Thanks for this addition! Since my knowledge so far not a single CMOS camera with global shutter on the market, I had my statement a little easier.

Antwort von WoWu:

There are a whole lot with global shutter CMOS .. the best known of Cypress probably come from Belgium, but synonymous DALSA builds to a large extent with CMOS GS, Texas Instr. CMOS has the most diverse with all sorts of additional features ....

Right!
Dear Z1 XH A1 or better!



Antwort von WoWu:

So it will be lightning fast because the consequences can unfortunately lead to the aforementioned effects.

Cj @ .. initially found the course DELSA chips in their own camera. From the Cypress chip was once the speech, he sitting in the RED. But there are probably rumors that the synonymous RS Effects shows, so it could well be that she has no Cypress chip.
Otherwise, it is of course a question of price, because GS chips put at least 2 more transistors and advance because of the image sensor of the most expensive elements in the camera belongs to each manufacturer will decide whether he does not prefer a little less quality.
Only it may be just talking out None that there were in CMOS can not .... the statement is simply wrong.



Antwort von Giagl:

@ wowu:
thanks for the info ...
the question was meant seriously, as I because of the reports
effects of RS in RED no further proficam with cmos know.

Already clear, but my statement that this peripheral discussion in motion has focused solely on "camcorder" in the ordinary sense. All of me - admittedly in name only - known Dalsa Cameras with global shutter CMOS cameras are for special applications, among others in the industry to aerospace. And that global shutter CMOS s.sich there, anyway, I had not questioned.

Antwort von WoWu:

@ cj

I have only synonymous meant .... and yes that is synonymous in this dilemma, in which we are stuck at the moment ... The industry is trying its cheap hardware to a consumer shift to make and on the other Page as half a thing, although expensive (since 7000 EUR is now no grad a bargain), but not reasonable durchkonstruiert if I s.die many quirks, except RS still thinking.
Since the decision is really hard and I see the same as you and watch with attention the chip manufacturers.
The thing I s.ehesten suspect is indeed a "break down" of the chip amounts from the photo in the video sector level. Because of the quantities, the cost-effective and with pixel binning, these madcap Resolutions synonymous reasonable channel and produce good qualities, because oversized chips are unfortunately synonymous lead back to the image degradation.
That is why I have your question correctly understood synonymous.
But I think we will have some in the professional sector with GS and CMOS seen at NAB. But, of course, is the desire 'father of the idea.



Antwort von WoWu:

@ Bernd

... unfortunately not the whole extent, because synonymous DALSA build something neat:

This part has really send the best of my knowledge, neither global shutter CMOS still convey a CMOS, but works on CCD-based, or not?

given the gibs Arri d20 equipped with cmos. we move forward with our cams but in the economy segment and this will be expensive-eng Dinos not compete. it would be the time for innovative image converter. I have something on-chips feveon read, they need no prismar for farbaufteilung. it takes is a single chip. Designed for the photography, camcorder would be here for a revolution, because the exposure of feveon the zelluloidfilm resembles.

Antwort von Giagl:

There are enough good chips s.Markt and no preference as to whether they have applications in industry or even sit in the drawers are the Manufacturer. The problem, unfortunately, sits lower, namely the unwillingness of the leaders, of their own low-priced foreign products on developments over to go.
The feveon chips are synonymous already relatively long, and are certainly a good replacement for the existing Bayer-mask ... synonymous but not Sony or Pana own production (unfortunately) and is synonymous not a substitute for modern CMOS developments, so many others, really have significant advantages.
One can therefore rotate and turn as you want ... there are good developments s.Markt, CMOS synonymous with GS, they exist in large quantities ... and thus relatively inexpensive ... but the camcorder companies want just their own products bring s.den man.
It is therefore not s.der technology, or because it did not exist, it is s.den companies and that they do not want.
That's why companies are synonymous, such as RED, the hope of the industry ... and now after they announced a small camera, they are probably synonymous the lower price segment of the prosumer it up yet.
Good so ...

yes, yes, Login ..

this is a disaster. synonymous if it is probably not an everyday situation is spinning. would an ordinary dv-camera better?



Antwort von DeeZiD:

A CCD-based camera - no preference whether DV, HDV, XDCAM, DVC-xx, etc. - would not have this problem, but unfortunately probably not synonymous these unbelievably good image quality of the EX1!

Did it myself since Wednesday and hellauf am thrilled and hope at least that I am not with her in such situations would be:)

From her picture she is still sympathetic to me than the "old" A1.
With the right preset (measured with vector scope, detail = off, Cine1 Gamma) looks like the picture of a good DSLR.

Antwort von Matoff:

The horrific news about the EX1 does not seem to stop and for some people here are always a feast to the adapter even though they never ien EX1 had in his hand. People, you take something back. I have Iene EX1 and I can now assess Very much that was aufgebauscht. Problems of the zero series cams are fixed and rolling shutter or not. If men are so spiritual and the reports of some rubbish to read, one could believe that with a reasonable EX1 no recordings are made. But God is there with her! The EX1 is loose and easily XH A1 ö.ä. in the shade.



Antwort von Ricardo Selzer:

The EX1 has undoubtedly your quirks. A perfect Cam under 10000 ¬ is synonymous of Sony's failure to give. However, we expect in this price class no grave blunders. Currently I am the Cam kompromissbehaftet too, so I wait from first.
A EX1 with an XH-A1 is already bold, those are two different price ranges and leagues. With the difference that the XH-A1 in relation to the price probably more satisfaction sprayed - ie the lower the price, the more existing quirks still tolerated.
I am curious what the namm offers. Hopefully, one EX1a repaired? ;-)

Owners vs. pride. Curiosity. Sure is aufgebauscht. The better the Cam, the more hair-splitting run. Cams For many, there is no critical thread, because they are simply uninteresting. The rolling shutter effects are not a breeze, maybe other things already. If you have the EX1 and're happy, good.
How would you in a club record, with many Strobos? Exotic situation, but you want to know. Very similar was the discussion on Optics of the XH A1 and the problem that - in fact, it is - not at the same time can zoom and focus (no vertigo possible).
