Panasonic AG-HMC83 HMC73 stronger than where?

Previously, we had a story about Panasonic Panasonic AG-HMC73's article about "Panasonic AG-HMC73 shoulder-high definition professional camcorder introduction", when approaching the end of last year, Panasonic has introduced a new model AG-HMC83. Then the difference between 83 and 73 in last place? Our approximate analysis.
 73 and 83 is basically a twin
Panasonic AG-HMC83 In fact, from the hardware parameters of the point of view, and before the birth of Panasonic AG-HMC73 no big difference, big change is the appearance is somewhat different, and later recording format to "regress" to the SD signal can be recorded, and other The basic nothing to say. Why the old model is a pure high-definition recording format, the new model again and then gave the old standard-definition format, "up" on it? This is progress or regress it? Let's analyze it and see.
 To the underestimation of the popularity of high-definition video
We Panasonic AG-HMC83 than the previous model but with the old SD record function point of view, explain the early popularity of products in high-definition video and application underestimated. To this end, the early "pure HD recording" is not compatible with standard definition models because the record the reasons, though after the listing reflects the strong, but because for some time that the AVCHD format HD video post-editing the outstanding issues, restricted the type of promotion and sales. The problems reflected by the market, so Panasonic felt before on the HD market estimates and judgments is unwise, because the popularity of high definition is not so simple, especially in this model is mainly for wedding market in mainland China, although This two-year wedding market growing fast, high-definition video demands are growing, but the Panasonic AG-HMC73 is a form of low-end models, the high-end services into it, it's just bigger in size point, less performance decent; into the low-end services to it, and because only shoot HD can not record SD, plus post-production and other reasons, do so in the wedding service "professional" camera makers can not be interested.
 Panasonic AG-HMC83 SD function is to adapt to market
As we said above, in the case, adjust the previous Panasonic "estimate" inadequate case, and out again on a model with the original record of the SD model Panasonic AG-HMC83. As a result, this AG-HMC83 both the high and standard definition recording format, for some, the low-end wedding video practitioners have a "top to bottom can eat" option. Although the overall original machine is still the basic configuration, but the record machine compatibility extends to solve many practical problems. Ye Hao technological progress, not a problem worth mentioning is backward, the problem is to determine the market a little earlier radical. As the saying goes: changed is a good comrade. The AG-HMC83 can record high-definition changed the "wrong", as long as the price allows you to accept, should be able to have a market.

Opened, "Paul Xia Puxiu HD9000 high-definition DV" the tiger

Recently saw an Taobao called "Paul Xiapu Xiu" (Polo sharpshots) HD9000 digital camera, also known as "treasure up" the price is only 900 yuan. There are other models such as the HD7000, the price of 700 yuan, sales are many. From the image point of view, these two models are "mighty", in particular, a relatively long lens makes a deep impression, for, on this low-cost high-definition digital video camera studied a bit, is the result.
 Seems to be little-known foreign brands
Start with "Paul Xiapu Xiu" to see the words, it seems that Japan's "Sharp" related to search for a long time in fact does not matter. From the camera body does not see Chinese characters, but in the introduction Taobao business point of view, the "treasure up" (PROTAX) to the issue of "network distribution power of attorney", "authorization" is the name of the issuer is a "treasure of the camera is limited company. " Finally a level to find this digital camera official website, figured it out is a Taiwan-funded factories in Xiamen, although not at the official website to find HD9000 this model, but the HD7000 is there may be a new product manufacturers forget his official website made it ... ... it may be Taobao businesses respond faster than the manufacturers do not know how ... ... then there come up with a "Paul Xiapu Xiu," the name.
 HD9000 (HD7000) of the basic functions
Because it did not find the official website HD9000, the HD7000 is only a fact of Taobao, said the HD7000 and HD9000 also no difference in performance.
The first is the HD7000 high-definition video capabilities, you can shoot 720P HD video up;
The second is the "dual power design", that is, you can use random rechargeable battery, you can also use two AA batteries, this design one can explain more "convenient", but also learn to see more "amateur", because although can not say that all cameras use lithium batteries, but at least I did not see the usefulness in recent years, ordinary AA batteries, of course, the design for the rural market is still more desirable, do not worry about some of the manufacturers of the DV Battery encryption issues;
The third is a double-swivel design. In fact, the LCD screen that can be opened from the bottom up, it can turn around and then rotate.
 Other major hardware configuration
 Pixel CMOS image sensor of 500 million (no area description), can be interpolated to 16 million (in fact, no use); video can record HD (720P) or VGA or QVGA up to 30 frames; built-in memory 17M; supports external SD memory card up to 8G; LCD screen of 2.5 inches; optical part is fixed focus lens, 8x digital zoom (the camera is basically a computer grade); telephoto lens (external) 60 times, 0.5 times as wide-angle lens; the HDMI output ; in webcam function, the other is no need to speak.
 Basic Comments
First, because this can record high-definition 720P DV video, so it "crowd in" the ranks of high-definition video camera, although it is far-fetched, and very true HD to DV "injured", but can not be said to be without just cause. Second, from the hardware configuration point of view, is indeed a more "cottage", such as "fixed focus lens," wide-angle and telephoto only by hand to "change the lens," of course, the lens is not a random external standard attachment, really is the "basic zoom by walking". Third, this "high-definition DV" (really do not want the word to use DV to HD on this machine) the advantages are obvious: First, a large head, a look is "mighty," out to shoot something is "bluffing "Most people do not see short-lived fad that is what" advanced equipment ", if the placement of a telephoto lens, ha ha ... ...; the second is cheap, HD7000 also seven hundred yuan.
Other areas: In fact, if spent on Taobao 700-1000 to buy a HD7000 or HD9000, then this really is better to use the money buy one such as BenQ W1240 (Jingdong price is 699 dollars) or Panasonic F3 (Tokyo price of 859 yuan ) digital camera, are "being eight by" things, 12 million pixels, 1/2.33 inch image sensor, can shoot 720P HD video. If you focus on camera features, you can also consider less than $ 1,000 for general DV1 and other products, of course, if the "face as the most important", you can consider this "fool head fool the brain," the guy.

Monster high-definition camera of the Sony NEX-FS100

Although the Sony because of Japan's earthquake affected by certain production, but this does not affect Sony's introduction of new products. Recently, Sony has introduced a so we say other than "monster" professional HD cameras NEX-FS100. We look at the NEX-FS100 in the end blame somewhere.
 Similar to the general assembly of building blocks
 NEX-FS100 seems to be no fixed "look," sometimes can be a "box" can also "dress up" into "guns" ... ... NEX-FS100's "body" and the lens and other elements can be separated combination of disassembly, it is a camera right, long like a camera, and using the camera's lens, you can also use a variety of camera lens adapter ring. Observed by NEX-FS100, it seems there is always the "camera" shadow, vaguely feeling a bit out of this product with the Canon by the "magic rabbit" fight about the level of meaning. For this topic, we will be dedicated to writing articles, please everyone's attention, now let's look at the NEX-FS100.
 Sony will position and professional products
From the search for the name of this model point of view, the "NEX" that the NEX-FS100 product positioning. From NEX-FS100 hardware level to see, it seems more like a digital camera structure. Because NEX-FS100 camera lens using a lens, no camera that can "power zoom" and other features; in image sensors, NEX-FS100 use 23.6x13.3mm called Super35 standard large area image sensor , record high definition AVCHD format, the maximum bit rate of 28M, and supports 60P \ 60i and 30,24 P or PAL system 50p/50i/25p variety of frame rates, so it seems, this model 60P and 50P record format, or have certain advantages, but the usefulness of this format is not very strong.
 NEX-FS100 features
We discussed above, NEX-FS100 construction of relatively more inclined to "digital camera", so, NEX-FS100 in the use of the original should also be more compatible with people using the camera, at least in the camera's operation is the case, this models must be true professionals choice, the average home user and used to "automatic" shooting people, best use is relatively easier to operate a "pure camera" better. NEX-FS100 Although located in the professional field, but its use of storage media supports the use of SDXC card, and not using the Sony EX series SXS cards. NEX-FS100 price positioning is relatively high, about 5 million yuan or more, the price should be said to be relatively high, do not know how many professional users "buy."

Infrared cameras can really see the human perspective of the clothes it?

The first two articles of our infrared camera principle is analyzed, the second article also shows that the infrared camera could be modified by a certain "conditional perspective", it is not we walking down the road people will be able to use infrared camera "perspective "out? Although this matter extremely small, but do not say absolutely that is not, but you can dress so to avoid such things.
Perspective is not terrible so-called infrared
Infrared perspective is not as legend so terrible, in fact, even if it was modified with infrared cameras, and can not "see through" all the clothes, the perspective is the use of infrared wavelengths of infrared light than visible light and long, have a choice of some of wearing a dark (eg black) non-cotton clothing like tights have a certain "perspective" effect, while the class of cotton and non-tight clothes is basically a "powerless" to. So, for most people, nothing to fear infrared perspective.
 From the dress to prevent "see through" the tricks
To actually make infrared camera perspective are mainly female name, usually in addition to the relatively thin summer wear or more "exposed", the people "perspective" of the possibility of larger, then there are some special occasions such as the swimming pool or gym etc.; if it is in spring or winter, because we wore the thick, do not consider this issue. Note that female compatriots in the summer, be careful not to wear tight clothes and translucent dark clothes, particularly non-cotton clothes. In some special occasion to pay attention to some, such as public swimming places. Olympics "Infrared Gate" Guo Jingjing perspective swimsuit event tells us that it is quite easy to wear swimsuits people "perspective", which is to pay special attention.
 From the photographer's camera or camera perspective to prevent
If you see someone holding a camera or a camera in the shooting, but the front of the camera DV or DC is not a normal transparent UV filter or lens, but a dark filter (IR Lens), then this person should be suspected is not modified with "infrared perspective" camera, in which case the best way is far from the point of this man, of course, if you wear more, do not ignore him, or even give him a supercilious expressing contempt ... ... if it is summer and wear relatively low, it is best to stay away from this person as soon as possible, in general, the perspective taken by the infrared distance it is unclear what the screen shot.

In addition, this special film by conversion to the "perspective" of the very few, most cases will not be met, so did not need to be too nervous, do not let this small interfering with normal work and life.

HD DV uses SDHC cards 2 Notes

With high-definition digital camera memory card normal, proper use of SDHC cards should pay attention, and if used improperly, to take damage or loss of important information will be no end of trouble. Now tell us using the SDHC card or other memory card should be noted, of course, the considerations mentioned in this article also applies to other memory cards DV.
 SDHC card should pay attention to the problem
The use of the memory card to take your place, please pay attention, do not let the card by external damage, such as not to bend or accidentally fell to the ground, etc.; in the plug, take the card, be careful not to let the hands come into contact with metal contacts on the card point; particularly careful not to cards in the sun and moisture exposure, etc. Not use a memory card, put card into the card's protective case, not random fling. SDHC card with card reader to upload data to the computer, try not appropriated directly from the USB port or SDHC card reader, it should first stop on the card in the computer-related (card reader) device, then dial the next time card, or memory card.
 Capture and storage using the SDHC card should pay attention to the problem
Although, the use of SDHC cards and traditional use DV tape recording is worry some more, but also pay attention to some problems. Shooting, continuous shooting tens of seconds or minutes usually is no problem, if the film requires continuous shooting for more than several minutes, pay attention to two issues:
First, pay attention to their long-shot DV fever, if the ambient temperature is too high, continuous shooting, high temperature may be due to the machine, DV will automatically stop recording until the machine can be started again after the temperature decreases;
Second, because the SDHC card is with FAT32 file format, so when the time is very long continuous shooting, SDHC card in a single file larger than 4G record, some may automatically stop shooting DV, although once again took over the capture key can be re- start recording, but may lose important content to be shot.
This problem is a lot of DV's instructions did not mention the use that may be encountered. Professional-grade DV when shooting long a file will automatically rebuild the other continuous record, some of the home does not automatically produce a high-definition DV file, choosing instead to stop recording. Therefore, in the long shot, be sure to regularly check the working status of DV, do not rack up the machine regardless of when the DV of about 4G SDHC card to stop recording to the record do not know, lost the need to take some important content.
In addition, because high-definition DV records video file is relatively large, so use SDHC cards, a relatively large number of capacity is another important aspect is to choose the faster, such as Class 4 or Class 6 SDHC card standard to ensure that the card read, write speed and high-definition DV to match

HD also points "true HD" and "fake HD" it?

A few days before the intention to see the official website of JVC, the camera found on its website products online like "true high-definition hard drive camcorder", "true high-definition flash memory camcorder," "standard definition hard drive camcorder" and "SD flash camera," Machine classification. A "true HD" makes a bit puzzled, what is "true HD"? There are really fake, it shows that because of "fake HD" will have a so-called "true HD." To this end, we as a topic to chat with everyone "true HD."
 What is "true HD" mean?
In fact, you want to know as "HD" such knowledge, it is easy to find on the network, in Baidu, a find a bigger. If you find a "true HD", then, can find out, just makes you look a little confused, because the so-called "true HD", it seems that HD 1080P or 1080i, but we are in the "HD" also see 1080P or 1080i, this is not strange, in the end "true HD" is what the open concept? We first answer said about it: the so-called "true HD" for high-definition camcorders is the recording format can be 1920 × 1080.
"True" cause of HD
 Say that high-definition, we can not talk about TV standards, because high-definition video camera is basically a "high-definition TV" service, or take back high-definition video on what equipment to watch it? HDTV refers to support for 1080i, 720P and 1080P TV standards. Basically all the big-screen LCD televisions, are "support" 1080i and 720P or 1080P; commonly known as "Full HD" (Full HD) is a TV that supports 1080P output. Why the "support" with a quote? Because many TV manufacturers are playing word games, what "support" and "compatible" or similar words on the publicity of their products, which made micro-plane and a car's dashboard and sometimes the speed to 160 km scale, but the car itself can not go 160 kilometers per hour, like dashboard "support" indicates the speed of 160 km, and cars can not explain the actual performance can be achieved this standard. That way, support the "true HD" video playback of TV, does not necessarily have the "true HD" video of the actual resolution; This is how it will appear true, false main reason for the high-definition.
 From TV to the physical pixel camera "true HD"
Digital camera CMOS or CCD image sensor "pixel" concept and we just said basically the same as flat-panel TV, flat panel TV's own actual pixels, the actual good TV can reach 1920 × 1080 pixels, which is in front of that. " Full HD "or" True HD "; some of the actual pixels of TV 1366 × 768, but this TV can also be" supported "1920 × 1080 video playback, but because of its physical pixels less than" true HD " number, the screen resolution is only a maximum of 1366 × 768, rather than the "true HD" 1920 × 1080.
JVC says "true HD", in fact, that it's "true HD" video camera can record standard of 1920 × 1080, but we have to understand, to record "true HD" video, can only be understood as we said earlier. " support "is the same," to record "true high-definition camera the image sensor pixels may not have the actual" true HD "standard.

From the "infrared door" to see the infrared shooting DV

Recently, the Olympics, "Infrared Gate" Guo Jingjing recent perspective piece swimsuit the matter is again making waves online. Why is that non-German photographed using infrared film can function "perspective" swimsuit it? Can the parties as an athlete or other methods through the dress, let photographed succeed it? We analyze the sub-articles to the outside shooting DV can not "perspective" people's clothes.
Infrared shooting DV
Around 1999, I purchased a Sony Digital8 format that D8 model DCR-TRV210E camera, the infrared shooting with the machine, the machine has a Nightshot also known as "night shot" or "night vision" switch, the switch is open, you can shoot in very dark environment to a more clear picture, but the picture is not black and white color. Later in 2004, bought a Panasonic DVC-33 Digital DV, the machine also has this "infrared night vision" feature, the "infrared" feature combined with a slow shutter technology, can be pitch-dark night in the shooting. Two days before the one we just made "Canon XF105 and XF100 features seven" article, Canon also introduced the latest release of XF105 and XF100 has "infrared shooting" feature.
 Active principle of infrared camera technology
We first look around the type of infrared camera, infrared camera about two, one is "active infrared camera technology", the other is "passive about outside the camera technology." We mentioned above, several models are "active infrared shooting", that is, active infrared camera technology is the use of special "infrared light" man-made produce infrared radiation, with infrared cameras record video feature watch these people irradiated by infrared light invisible objects. This infrared radiation of infrared light, the human eye can not see, such as we often use the TV remote, press the button, by remote control infrared light to send the TV remote control commands, but we do not will be issued from the remote control to see the light, because the human eye can not see infrared light, so only "infrared" and "Ultraviolet," saying that we humans can only see "red" and "Purple "within the light, but the camera's CCD image sensor can capture infrared light, CCD not only can" see "the light we can see, but also" see "we do not see the light.
 DV principle of infrared
In fact, the above said, we basically understand how it was a child. With infrared shooting of DV, or other location at the bottom of the lens to protect the red hood, equipped with a set of infrared night vision devices (two or more infrared light-emitting unit), can be opened without any light shooting conditions to obtain a clear black and white images. Built-in infrared night vision devices for the effective range of about 3-5 meters, while the optional high-power infrared light photography the maximum effective range of up to 30 meters, such as the above mentioned Panasonic DVC33 on this accessory, you can burst News, shooting wildlife and public security and other special industry provides a professional image acquisition tool for all-weather activities.
