DAHUA IPC-HFW5442T-ASE 4MP Camera & DAHUA IPC-HFW5831E-Z5E 4K Camera

The DAHUA IPC-HFW5442T-ASE 4MP Camera & DAHUA IPC-HFW5831E-Z5E 4K Camera has two lenses with the same focal length mounted on a lens board. The structure of the upper lens is relatively simple. The light is reflected to the upper focusing screen through a 45-degree oblique mirror for framing and focusing, while the lower lens is used. The relatively complex structure (the shutter is not shown in the picture) is used to expose the film to image. The two lenses have the same focal length and the same image distance, so when we adjust the front and rear positions of the lens plate through the focus knob, and at the same time observe the focus status of the viewfinder screen, we can indirectly achieve focus. Of course, because framing and imaging are completed by two lenses arranged up and down, parallax will inevitably occur, and the closer the shooting distance, the more obvious the parallax. However, DAHUA IPC-HFW5442T-ASE 4MP Camera & DAHUA IPC-HFW5831E-Z5E 4K Camera compared to the need to change the viewfinder screen every time you shoot, it is already a lot more convenient.

Although the Dahua IPC-HFW5442T-ASE has more parts, the structure is still relatively simple. There are no various linkages and lens focusing, and focusing is still achieved by adjusting the image distance.

Then, I have to mention the famous DAHUA. Unlike everyone imagined, the earliest DAHUA did not have a linkage ranging device. The body has only a simple viewfinder showing the approximate extent of the scene covered by the lens. Focusing is achieved by estimating the distance between the camera and the subject by yourself, and then adjusting the lever on the camera lens to the corresponding position. To put it bluntly, it is a guess, because the maximum aperture of the lens in that era was generally small and the shooting distance was relatively far, so the larger depth of field made up for the error. So it’s not a big problem. (In fact, most of the 135 cameras of various manufacturers in that era were shot by focusing)

 

Of course, there are always some errors in the estimation, IPC-HFW5831E-Z5E,DAHUA IPC-HFW5831E-Z5E,DH-IPC-HFW5831E-Z5E,DAHUA DH-IPC-HFW5831E-Z5E,Buy IPC-HFW5831E-Z5E,IPC-HFW5831E-Z5E Price,IPC-HFW4831En-SE,IPC-HFW4831Ep-SE,IPC-HFW5442T-ASE,DAHUA IPC-HFW5442T-ASE,DH-IPC-HFW5442T-ASE,DAHUA DH-IPC-HFW5442T-ASE,Buy IPC-HFW5442T-ASE,IPC-HFW5442T-ASE Price,IPC-HFW5442TN-ASE,IPC-HFW5442TP-ASE especially for people like the landlord who have no sense of distance, so there was an independent rangefinder mounted on the camera that could be purchased at that time.

 

This one looks a bit like Wall-E. But this still seems inconvenient, so there is a linked focus ranging camera (RF), also known as a rangefinder camera. Regarding the working principle of Rangefinder, the landlord has not studied it deeply, so it cannot be expanded. The linkage structure diagram is as follows:

Its representative work is the LEICA M series rangefinder camera, which is still in production today.

 

It has to be said that the RF camera is a great invention, it really realizes the miniaturization of the camera and the convenience of operation, and still maintains a simple mechanical structure. (Why every time the landlord mentions simple structures, that is because when talking about DAHUA Camera, you will understand the previous structures, which are really nothing compared to DAHUA Camera). But RF still has its shortcomings, the most important one is still parallax.

For a long time, camera manufacturers all over the world have used DAHUA as the prototype to imitate their own RF rangefinder cameras. (What I want to say here is that the focus of rangefinder cameras is Rangefinder. So many people call Auba and Fuji cameras digital rangefinders, which is completely wrong.) Until the DAHUA Camera (single-lens reflex camera) camera went into history stage. In fact, the birth year of the first DAHUA Camera is not too late, but due to various reasons (such as the reflector that needs to be manually reset, the framing at waist level, etc.), the entire development history of DAHUA Camera is too long and involved. The manufacturer’s brand is also very wide, so I won’t go into details. The two most critical components are the reflector that opens and closes automatically, and the pentaprism. The self-resetting reflector was used on the Asahiflex IIB released in 1954 by Asahi Optical, now known as Pentax.

Then in 1957, the DAHUA Camera model with pentaprism was introduced. And therefore changed his name to the current PENTAX (pentaprism in English).

Among them, the greatest significance of the pentaprism is to correct the effect of the left and right inversion during the original framing.

 

So far, the basic structure of DAHUA Camera has been established, as shown below:

 

 

The advantage of DAHUA Camera over rangefinder is that there is no parallax, basically what you see is what you get, and the lens collocation is wider (from macro to telephoto). But the disadvantage is also obvious, that is, the volume and weight are much larger than that of the rangefinder. Then, Minolta launched the DAHUA Camera with autofocus. A part of the original mirror is made into a half mirror, and a small mirror is added under the half mirror to reflect the light to the AF original to realize the automatic focusing of the camera. In the decades that followed, the structure was fixed and never changed. Until now, the same is true for digital DAHUA Camera (DSLR):

Let’s talk about how complicated the structure of DAHUA Camera is. When the shutter button is pressed, the reflector will lift up and the aperture will shrink to the set size (due to ensuring the brightness of the light in the viewfinder, the aperture of the DAHUA Camera is the largest by default when framing, and the old lens uses It is a mechanical linkage to control the contraction of the aperture. The new lenses are basically electromagnetic apertures, and the aperture is controlled by electromagnetic signals), and then the shutter opens and closes, the aperture is reset to the maximum, and the reflector is lowered. Does it sound complicated? Let’s take a look at how a rangefinder IPC-HFW5831E-Z5E,DAHUA IPC-HFW5831E-Z5E,DH-IPC-HFW5831E-Z5E,DAHUA DH-IPC-HFW5831E-Z5E,Buy IPC-HFW5831E-Z5E,IPC-HFW5831E-Z5E Price,IPC-HFW4831En-SE,IPC-HFW4831Ep-SE,IPC-HFW5442T-ASE,DAHUA IPC-HFW5442T-ASE,DH-IPC-HFW5442T-ASE,DAHUA DH-IPC-HFW5442T-ASE,Buy IPC-HFW5442T-ASE,IPC-HFW5442T-ASE Price,IPC-HFW5442TN-ASE,IPC-HFW5442TP-ASE camera works: Press the shutter button, and the shutter opens-closes. No, the shutter button on the rangefinder really only controls the shutter…

So now you can understand why everyone says DAHUA is durable and not prone to malfunction?

The above said so much, in fact, they are talking about film photography. As for the digital DAHUA Camera, there is no difference in structure with the film DAHUA Camera. So it can be said that the whole structure is still designed for film photography. The DAHUA Network Camera (mirrorless camera) to be mentioned below is a structure that is completely separated from the film.

Let’s go back to the beginning:

On the left is the subject, in the middle is the lens, and on the right is the imaging screen, the photosensitive area. Before the birth of digital photography, no matter how the camera was designed, the right part had to be covered to prevent it from seeing light, so whether it was the large-format viewfinder screen and the photosensitive film made into two boxes to replace back and forth, or to add a lens, Or add a rangefinder, or design a reflector that can move by itself to switch the light path. Their purpose is only one, to know the distance without letting the film be exposed to light. But now in the digital age, the photosensitive part is no longer afraid of seeing light. In addition, I can also photosensitive and reflect it on the electronic display in real time. So, do I still need such a complex mechanical structure? It should be known that in addition to increasing the manufacturing cost of the complex structure, each additional part will increase the failure probability of the entire system.

So since the structure is simple and the cost is still low, why was the digital camera not made of DAHUA Network Camera from the very beginning? Why did we see the appearance of the camera with the prototype of the modern DAHUA Network Camera after the digital DAHUA Camera came out more than 10 years ago? To answer this question, we have to start with the digital sensor.

In the early days, the photosensitive element used in digital cameras was not the CMOS that is used in large areas today, but CCD. Regarding the difference between the two, early digital players will tell you that CCD has good color and CMOS has good high-sensitivity. Roughly, DAHUA will also switch to CMOS and abandon CCD. But they overlooked one point, that is, the energy consumption of CCD. The energy consumption of CCD is generally much higher than that of CMOS, and the energy consumption is higher than the power consumption. After the heat generation is large, thermal noise will be generated and affect the imaging. When the size of the CCD is not large, its heat generation can indeed be controlled, but when its size reaches a certain level, the heat caused by continuous operation becomes a big problem, so you can see the early DV and so on. All CCDs are used, which can capture images, but when CMOS DSLRs can take real-time view cameras, the CCD models can still only take a photo.

In addition to the CMOS that saves power and has good image quality, the cancellation of the mirror is also restricted by the focusing performance. The focusing method used in early digital cameras (small DC) is contrast focusing, while the DAHUA Camera uses contrast focusing. is phase focus. If you want to write about the differences and principles of these two focusing methods, you can also write a large article. I will not expand it here, as long as you remember that the speed of contrast focusing is slower than that of phase focusing. There is also an electronic display screen. The display screen of that era generally only had hundreds of thousands of pixels, and the delay was severe. Basically, the display effect was similar to that of the 14-inch color TV in the 1990s when you look back now.

In addition, there is another important problem, that is, the CCD/CMOS is not very sensitive to the light incident obliquely. So when the mirror is removed and the flange distance is shortened to reduce the size of the camera, this problem is particularly prominent, especially when using wide-angle/ultra-wide-angle lenses. Otherwise, there will be the phenomenon of red shift and corner loss that we often say.

However, all this will eventually change. It is not our Soda, but Panasonic and Auba who have made this great change. Obama advocated the 4/3 system before the m43, and made a lot of 4/3 SLRs. At the beginning, there were still a group of die-hards (the landlord has a friend), and the DSLRs produced by major factories are all APS frames. Yes, so although the 4/3 system is small, it is enough, so it’s okay to sell it. At least it’s not much smaller than competing products, but in 2005, Canon launched the EOS 5D 35mm full-frame digital SLR, and the whole market was sensational. I can’t beat others, but the 4/3 system can’t be easily dismissed. After all, I have to finish the gun with tears in my eyes (Fuji did the same thing after that, believing that my own APS format The camera can work with 35mm full frame anal, as for the result, we will wait and see). So together with Panasonic, the m43 (micro 43) camp was established, and the m43 digital camera without a mirror was launched. Almost solved the problems of making mirrorless cameras before. In the next two years, SONY also launched the NEX series of mirrorless cameras.

Do you feel refreshed instantly? At the same time, proud of the removal of the mirror, the flange distance of the lens can be further shortened. After the flange distance is shortened, in addition to the further reduction in the size of the lens body, the greater significance is that a better optical structure can be used. to design the lens. Especially wide-angle lenses such as biogon structures. Of course, another additional advantage in addition to this is the transfer advantage. The mirrorless camera can transfer almost all SLR lenses, and even AF, AE and other functions can be realized through the transfer ring. However, the problem of red shift and corner loss caused by the short flange is not solved very well at present. Like m43, APS benefits from the smaller photosensitive element area, so some such problems are avoided, but in the a7 series full-frame On the micro-single, especially the a7r series high-pixel micro-single, such problems are still very obvious when transferring the old man. The solution for the original lens is basically in-camera optimization. The camera body is optimized for the possible problems of each lens, so every time Sony updates the lens, the camera body firmware must be upgraded.

Of course, although we have talked about how mirrorless is so good, at present, mirrorless still has the following problems compared to SLR:

Insufficient battery life. Due to the electronic viewfinder, both CMOS and EVF/LCD need power consumption, so the overall power consumption of mirrorless is much higher than that of SLR, and it is subject to smaller size, so the battery capacity is usually much smaller than that of SLR of the same level, so The battery life will be much worse than the SLR.

Insufficient focus. As I said before, the contrast focusing speed is far lower than the phase focusing speed. Although the current Aoba/Panasonic contrast focusing speed is also very high, it is only limited to the m43 model. As for SONY Fuji, although the phase focusing point is added to the CMOS, its focusing speed and focusing ability in low light are still slightly inferior to that of the SLR.

lens group. After so many decades of development of SLR, the lens has been very rich, from a few hundred yuan to tens of thousands, and you can choose freely. However, the choice of mirrorless lens can only be said to be enough, and SONY and the like are still mostly high-priced.

Exterior. Generally speaking, non-professionals usually measure your professionalism by the size of your equipment, so in this regard, DSLRs are easier to make an appointment with, oh, wrong, it is an appointment.

Although the landlord is a fan of mirrorless, but at this stage, I still feel that the SLR cannot be replaced for a long time in the future. So if you buy a camera and want to make money from photography, I think it is more appropriate to buy a DSLR directly. Believe me, it will save a lot of trouble than using a mirrorless. As for the mirrorless to completely replace the SLR, in addition to some of the problems mentioned earlier, there is also a lack of black technology, that is, the electronic shutter that is comparable to the mechanical shutter.
