Why don't micro-singles and SLR use Android instead of the current firmware?

Because it's not made in China. They don't serve the people.

Android was originally designed for cameras.

According to andy rubin's original plan, Android itself is a camera system running on a camera. It uses cloud storage to upload photos or videos, so that users can access photos from the cloud at any time without considering the problem of insufficient storage.

It was in 2004, and the concept of cloud storage was so "advanced" that no investors paid attention to it.

Five months later, their team found that the market share of digital cameras was so small, otherwise we wouldn't have built a mobile phone system.

Later, it was acquired by Android and Google, and HTC Dream was launched together with HTC*** (historically called G 1).

Cann't run away

Before the third generation, Sony was equipped with the subsystem of Android.

There are many official applications that can freely expand their functions. Even if you have a little hands-on ability, you can install the normal APK of Android through "certain operation".

Interested students can watch this project on github:/ma1co/Sony-pmca-re.

However, the actual experience is a long story. Long boot time and extremely slow response.

So after the third generation, Sony cut off the system. In the end, I still can't run.

Take the famous Sony A7III as an example.

A7III adopts Bionz X processor, Sony CXD4236 ISP and CXD90027GF SoC.

This ISP cannot find specifications and parameters. Let's talk about SoC CXD90027GF first.

Arm Cortex-A5 architecture based on quad-core.

The most famous representatives of this series are Qualcomm Snapdragon S 1 and S4 play series. S 1 It's too early. Let's talk about S4 drama series.

The representative models are MSM8225 and MSM8625, which can support dual core 1.2GHz, the secondary cache is 5 12K, and the technology adopted is 45nm.

For example, MSM8625, using this processor are:

Basically, it is the era when "China Cool Alliance" dominates the world. Basically, it is a contract machine for operators. It will be delivered after charging two or three hundred phone bills, and it will be sold around 20 12.

If you still don't understand, the upgraded version of MSM8625 is MSM8625Q, which belongs to Snapdragon 200 series and Snapdragon 200. Now that Snapdragon 888 has come out, some people think that 865 is a bit stuck, not to mention Snapdragon 200.

Even if I calculate, I can run Android smoothly.

Is it necessary to have a good screen How else to retouch the picture? If you don't retouch Weibo, it's meaningless to install an Android.

But as you can see, it has been scolded for almost ten years. Sony Dafa is the leader of our micro-single.

The screen is still a piece of shit.

Does a good screen need a good ISP? A bigger battery?

No, after all, micro-orders are not cheap now.

Besides, your need to send Weibo is really so urgent that you need to send it right away? Moreover, NFC and WiFi of cameras are also very popular now, and it is also very simple to transmit them to mobile phones. ...

Don't worry about that half minute.

In fact, there are also micro-singles using Android.

For example, the Samsung galaxy s4 zoom released on 20 13 uses the Android 4.2.2 system.

Some people say, isn't this just a mobile phone? Yes, it's a mobile phone.

But it seems that there is nothing wrong with calling him a camera.

In addition, Samsung also made a Galaxy NX, which really has little to do with mobile phones this time.

Using 20.3 million APS-C sensor, the sleeve is the famous 18-55.

Quad-core processor, Bluetooth, 4G, WIFI, GPS, whatever.

On the one hand, this fuselage design is quite sexy. If I remember correctly, it was more than 10 thousand when it was first listed, so few people bought it ...

For another example, the domestic Yongnuo YN450 finally came out almost two years later.

Adopt M4/3 frame, processor Snapdragon 625, Android 7 1, 4G network,160,000 pixels.

Call him a camera this time. No problem.

Moreover, a second-generation model has come. If you use 1 generation, you can switch to the second generation for free.

In addition to Yongnuo, there are also products from internationally renowned manufacturers, which actually use Android.

ZX 1 of Zeiss, a major optical manufacturer.

37 million full-frame sensor, customized Android system, built-in Adobe Lightroom Mobile.

What can I say about performance? So-so. In 2020, 4K/30p, 1080/60p, the maximum continuous shooting speed is 3FPS, which is not really "slow", after all, "three-frame e-sports".

The 4.3-inch 720P screen, although it sounds rubbish, is still very awesome in the camera camp.

The price is 6000 yuan, almost 40000 yuan. It is not good to buy a camera.

In fact, the word micro-single is not rigorous at all, if the micro-single in your mouth means "mirrorless" camera.

Then, the mobile phone is also reflexive.

The camera needs seconds to turn on, but Android doesn't. The camera requires good standby, low hardware power consumption but slow start, and high hardware power consumption. But a camera system can satisfy, why do you want to make such a complicated system?

The firmware of the camera is written in the hardware, which belongs to hard operation, similar to industrial plc.

It is more reliable, faster, and has lower requirements for hardware, bypassing the operating system, so the speed of direct data exchange between hardware is faster, which is why an old camera can instantly display the image on the screen after shooting, which is also more energy-saving.

In addition, because the main function of the camera is to take pictures, image processing and data exchange are very important, and only hard operation can meet these needs. In addition to the interactive function of Wi-Fi, there is no need to run an interactive operating system that takes up a lot of resources, so the popular operating system cannot replace the existing firmware system.

For a long time, the mirrorless camera will soon replace the SLR as the standard of the next generation of photographic equipment.

Its argument is based on four reasons.

Its camera is smaller, lighter and easy to carry.

Secondly, without the constraint of the mechanical limit performance of the mirror, the continuous shooting speed can be faster, and at the same time, you can shoot while continuous shooting.

Third, there is no flange distance limit, and the lens can be transferred at will.

Fourthly, there are no mirror parts, expensive pentaprism parts and special focusing parts that require high model performance, which can save a lot of costs and is cheaper than the same grade SLR.

The above is the biggest advantage of no anti-SLR. Of course, at present, the continuous shooting speed of the camera is mainly limited by the transmission speed of CMOS (so after Sony replaced the back-illuminated CMOS, the continuous shooting speed went against the sky, while Nikon Canon can only achieve the same continuous shooting speed by reducing pixels). But in fact, the mechanical limit of reflector also exists. Throttle rejection on 1DX is a negative case. The advantage of canceling the flange distance mainly lies in the transfer (after all, the optical principle of the lens is there, and it is difficult to generate enough image fields to cover the negative without enough distance). The flange distance of SLR is basically about 43mm (that is, the diagonal length of 135 negative film, and there is no distortion and image quality loss at this flange distance. Of course, shorter flange distance can also be used for imaging, but some image quality will be lost. For example, Sony RX 1R and A7 can be known by comparing with Zeiss 35/2 lens. This is the best imaging distance on 135 negative, which can't be ignored.

Next, let's talk about the disadvantages of not being able to.

One: poor grip, which is very important for long-term use, especially in the field of professional photography. It is very important to hold it comfortably and stably. In order to reduce the size, the grip is far less than that of SLR (of course, Panasonic GH5, Fuji XH 1 and Sony A99 are bigger than many SLR's, but these big guys can't do it and lose their portability).

Second: reaction speed. No matter whether the SLR system is turned on, awakened or focused, its reaction speed is better than no response. Start-up and wake-up speed: I think if I have used Sony A7 series, I should feel it. It takes at least 2 seconds to take the first photo (SLR does not take 0.5 seconds from the start of the portal to taking the first photo). As for focusing, although the camera has many focus points, focusing has great advantages (but it must be focused for the first time before focusing). The single focal speed does not reverse. The focusing system based on CMOS is not as good as the independent focusing system of SLR (both accuracy and speed). For example, in order to improve the focusing accuracy, Sony uses several or even a dozen focus points to calculate together and then take the average (the amount of calculation is several times that of SLR system). In terms of single focusing speed (same lens, such as Sigma), the strongest Sony A9 is not even as good as the worst SLR Pentax K 1. However, in the following focusing stage after the first focusing, it is not easy to lose focus because of its large focusing coverage area.

Third: protection and weather resistance. This is the most important performance for outdoor use. Although Sony also marked splash protection, A9 was still seriously flooded in the weather resistance test of DP (Artificial Spraying Simulated Rainfall), even because the water was completely short-circuited. Nikon Canon's professional machines D5 and 1DX2 passed the test easily. Similarly, the strength of the fuselage is greatly reduced because of its small size, which can be said to be very resistant to falling compared with SLR. (Leica T is a special case).

Fourth: poor portability (high-end products only)

Yes, you heard me right. There is no contrast between the portability of the anti-system and the single comparison. First of all, the high-end reflex-free system is not much smaller than the same level SLR. But at the same time, the high-end non-reflective lens is larger than the SLR lens. As mentioned earlier, the flange distance of 43mm is inevitable (nothing more than on the lens or the fuselage). In fact, the nonreciprocal system is not as light as the SLR system (refer to A7R3+GM720 and D850+720E).

So you will find that the non-reciprocal status is actually embarrassing. The advantage of no anti-SLR is that they are all in the civilian field, and the advantages of professional SLR are very obvious. This means that the position of SLR in the professional field (including outdoor civil use) is difficult to be replaced. For general civilian use, most people pursue small and light (that is, the main buyers who have no objection at present), and there are better and lighter choices in this field, such as cameras with no lens change at the bottom, such as Fuji's X 100, Sony's RX, Ricoh's GR and so on. These big-soled card machines that can really fit into pockets are the real main force in this market. However, many advantages over SLR can be easily compensated by SLR system, such as the built-in electronic viewfinder behind the pentaprism. After all, the LV system is quite mature in SLR, and it is impossible to lack the display of eye screen.

Why don't contemporary digital cameras use Android instead of existing firmware?

Let's take a look at the digital camera of Android system first. In fact, as early as 10 years ago, Samsung once produced an Android digital camera GC 100 in 20 12, and then it had an upgraded version of GC200 in 20 14 years, with the system version number probably Android4.3.

Let's take a look at the Android system again. The first Android phone in the world was in 2008, and the earliest production date of single-lens reflex viewfinder camera (SLR) was 1909, which means that the camera was earlier than Android system 100. Although the film age has entered the digital age, the imaging principle of SLR was basically the same as now. To put it another way, if 10 years ago or 5 or 6 years ago, due to the limitations of the Android system and the configuration conditions of the mobile phone processor and memory, everyone knows that the Android phone will be stuck after a period of time, and the system has many loopholes and the security is worrying. It's only been two years since I started using Android phones.

Although we don't know the use perception and ultimate fate of Samsung's two Android digital cameras, the first real digital camera in the world was born in 199 1, which was 17 years earlier than Android phones. After nearly 30 years of development, the system firmware of digital camera has been very mature and stable, while Android system has been stumbling, and it has only stabilized in recent years and decided to shoot and image. So why abandon a mature system to use an immature system? Android has many loopholes. In addition, Android is an open source code, although protected by law, but basically anyone can modify it. Assuming Canon uses Android as firmware, it may form a firmware with Canon orthodoxy and a firmware with abc reviser, which will be confusing and the security of the system will not be guaranteed.

In addition, the current Android system is very mature, the fluency and security of the system have been greatly improved, and the current mobile phone is thin and light. As a communication tool, the shooting performance of mobile phone is getting stronger and stronger, which can completely replace the digital camera of Samsung Android system. As a manufacturer of digital cameras of major brands, we will not rashly produce an Android digital camera that we have no advantages or even disadvantages.

Even if the current Android system is very stable and mature, why should both SLR and micro-single use Android system? If you use Android system on the current digital camera, compared with the firmware of the digital camera, the biggest advantage and the most practical is that you can surf the Internet. The so-called mobile phone can improve the imaging effect by relying on some algorithms of AI, but it does not play a decisive role for digital cameras. Another biggest reason is that the digital camera already has a very mature and good firmware, so why use a firmware controlled by others, that is, Android system? Think about some domestic mobile phones that have encountered this problem and have not been used after paying the money.

Of course, the Android system has its unique advancement. With the advent of the 5G era, there may be a firmware belonging to the digital camera itself, and then a module belonging to the Android system can transmit the captured images to the Internet in real time. Anything is possible.
