Infoseite // Autofocus in low light - Sonyoder Panasonic?



Frage von Thomas.L:


Hi All,

after long use my analogue Panasonic NV-S88 to me now I want to take home a digital model. Especially interssieren me the 250 and 400 of Panasonic. Now I have heard of a seller that the behavior of low-light digital camcorders will be worse than the old analog video cameras. I was also a focus of the car with my old Panasonic is not necessarily convinced. The auto focus was not always immediately accurately (pumps) and has required a very long time to adjust the sharpness of it right. An acquaintance of mine who was at the same time an analog Hi8 camera of Sonybesaß as far less problems. There are between Panasonic and Sonyheute still synonymous differences in the low light behavior, and especially the autofocus performance? Here Sonyweiterhin good?

Gruß Tom

Hello Thomas.L,

Auto Focus when it will be difficult for other Fimen the AF time to create.
If one already synonymous with entry-level model HC 17, how quickly you can find is gebenüber GS 17, D 245 or MV 800 is the correct distance.

The same goes for the low light quality, although s.der GS 250, the Panasonic's can compete fairly.

Well those are 2 Panasonic weaknesses, Panasonic camcorders tend to have multiple connections (eg microphone jack), or
a full-supplied charger. Most 3CCD models are synonymous in daylight, the better picture compared to equivalent Sony. Also nice in GS 250.400 Scharfstellring to adjust the distance - for many Sony's incl HC 90 through touch screen.

Is a matter of opinion, but if AF include sleep time or light to your most important criteria for inclusion, then it will probably ne Sony.

Hi Tom,

digital camcorder that will have a worse lowlight behavior, you have to differentiate. The rule of thumb: The smaller the CCD imager are the worse the reserves in Schwachlichtbereich. Furthermore, a decent 3CCD camcorder is better than a device with only an image intensifier. The new (billliger producible) CMOS image converter, cut in bad lighting, however not performing well.

Hast du mal a SonyVX2100 the Picture (3 × 1 / 3 "CCD) seen in low light conditions? You would think the seller is no word!

I think the vendor has obtained up to 500 euro price class.
di analog cams were simply better in lowlight, since although they had just Fross CCDs, but usually only 360k pixels.
it depends not only on the ccd size, but on the relationship btwn the CCD size and pixel number and the resulting pixel size.
But clearly, the new cams oberklasse be better!

furthermore, I would you, when are you arriving at lowlight recommend synonymous sony cams.

villeicht you will also find somewhere ne used VX2000.
The gibts to participate even for relatively little money.

Hi Thomas!

From the reviews from other manufactures the Panasonic camcorder while better colors (synonymous in low-light), however, have Sonybeim autofocus is still better.

In addition to the sharpness and color reproduction, I would be in low-light area, however, synonymous always take into account the tendency to smear effect with. Here are the CMOS camcorder of Sonygut.

Otherwise, the old rule applies: try it out!

Greeting
Nightfly.

At the moment there's only 2 Sony's CMOS with the PC 1000 and the HC 1st But we can bet that comes out in the near future, a successor of the first CMOS camera but disappointing SonyPC 1000th Well, we can surprise us in the digital field only pushes Sonyim moment many unexpected news to the market, such as eg N 1 or M 2

The problem is the camcorder during AF usually only work with a simple contrast measure which simply is not as good at LowLight: http://de.wikipedia.org/wiki/Autofokus#Phasenvergleich Other methods are technically complicated and too expensive to integrieren.Sehr old VHS-C/Hi8-Camcorders upscale haten yet sometimes also an infrared auto-focus (this is absent from the Wikipedia article?), which are then in LowLight course, lengths better than the modernen.Ich had himself here once a SVHS-C camcorder, the firm where the lion external infrared illuminator could be connected and plugged in the accessory shoe, this worked very gut.Schade the infrared method is extinct because indeed seems to be gewessen technically quite feasible, since the camcorder manufacturers can save I think s.falschen corner.

What would be the right corner to save money? Image quality, LowLight behavior, lack of microphone jack, headphone jack missing, flashy drive noise, ... there is indeed synonymous everywhere already saved! Who "greed is Geil" assisted living needs with something simple.

The video films has never been a cheap hobby. And anyone who still wants to have cheap, it gets just synonymous cheap - in price and quality.

That's why there's an article in the newspaper synonymous focus on Wikipedia, where so many users superficial knowledge / ignorance reinstellt in Biblothek. I was looking for something synonymous least, was able to demonstrate through a link to the post at least one of the two hacks were totally wrong, because everyone else was claiming. I would therefore synonymous reinstellen nothing there, and even plenty of magazines to write untruths in their reports.

So simple is it with the AF but not a large number of users do not even move when the AF lens groups eg, at a different lenses are rotated, synonymous, the question is how good is the processor - as fast as he can, the data from the CCD further processing, Canon and Sony are in the dot is usually very good, especially Pana and JVC have a little pent-up demand.

I fit in so synonymous with Wikipedia, if I make a statement on a layman's vorkommt.Es just goes (still) always add anything about a real book with renowned author, because None is purely what he wants and knows exactly what it is man rather than a cobbled together 100erter Declaration of unknown people.

Travelers Linsenschienen I know (especially since I've cut so that part time * g *), with the rotating threaded lens is naturally a bit slower, which cause a bad signal processor during AF can I have experienced with one s.alterschwäche slowly dying, old camcorder had time : ~ 3 seconds response time even with AF-1A light. Consumercamcordern problem but is often the combination of sensor data with the complex frequency spectrum analysis of the image in the signal processor (proof of Processor: High "frequency" in this spectrum = increasing severity, the other way a fuzzy picture looks like a low pass filter, it focuses to the frequencies and hence blurring past). Consumercamorder but they offer first, unfortunately, almost never bildmittenbetont selectable focus points, as in many Digicams (, Spot, etc.) was deteriorating schonmal individual vote (really bad) and secondly because (too dark images for the AF often barely may still be sufficiently high contrast) there is a problem especially since it will be synonymous with increasing LowLight especially so difficult because the data are recorded directly from this analysis by the sensor (have) and not by a possible gain or illumination through the shutter - and thus is remains especially for the Low Light capability of the AF as a bottleneck or only hope for the light sensitivity of the sensor and the Optics and since it is precisely in Consumercamcordern rather faint, small sensors will be installed and more fainter Optics, AF may simply not be good enough to interfere even an inexpensive digital signal processor (JVC-ridden?), it will have once synonymous with 60W-room light with the AF s.and too narrow.
