1. For this CMOS, Canon has added an attribute: Canon’s first [full frame] back-illuminated stacked CMOS. In other words, this is not Canon’s first back-illuminated stacked CMOS… As far as I know, the owner of this name is G7X3 (in the camera field, I don’t know if there is an earlier Canon product in other fields, and I don’t want to check it. Up). The slogan of G7X3 is “1.0 “stacked CMOS image sensor”, it does not mention the back-illuminated type, but from the schematic diagram, the pixels are on the circuit layer, which is also back-illuminated. Canon’s stacked CMOS does not say that it integrates on-chip DRAM , EOSR3’s disclosure this time reveals the element of back-illuminated stacking, which is also the characteristic of CMOS. If DRAM is integrated, there is no reason not to mention it. Then in the style of Canon, it can be judged that nothing is said = no. It means that it is similar to Sony’s. Exmor RS is still different. Exmor RS is integrated with on-chip DRAM. We are not professionals and we don’t understand the specific technical differences. I still know this question before, but obviously there are very few answers, and there is no reliable answer. But in any case, the data output speed of stacked CMOS must be greatly improved, which is conducive to reducing distortion and jelly effect under the electronic shutter. The information disclosed this time also mentions this. 2. Didn’t say whether there is 8K, maybe As some analysts have said, EOSR3 is a low-pixel speed machine, and the number of pixels cannot meet 8K, and it may remain in the next disclosure. However, the Z9 is officially announced as having 8K. Would it be willing to owe Canon’s character? Back, the specific 8K specifications of the Z9 are not clear, and it may be of little use value, and for this box flagship machine aimed at the Olympics, whether there is 8K is really not as important as imagined. 3. 30fps under electronic shutter The continuous shooting speed, the specific details are unclear, or it is difficult to judge. From the performance of the R5, it should be at least usable. I estimate that the Z9 should be 20fps, but for taking photos, the continuous shooting speed is increased from 8. To 12 or from 10 to 15 gives people a stronger perception. Is the perception of 20->30 really strong? Anyway, as far as my experience of shooting Feiyu is, there is a 14fps that is completely enough, and the continuous shooting speed is too fast There are too many repetitions, really. Choose the crematorium. 4. Eye-controlled focus, EOS3 resurrection, it is probably one of the reasons for the name R3, it can be regarded as the original source of the word “eye-controlled focus.” Sony took charge of his focus point. The system that tracks the subject’s eyes is called “eye-control AF”. “eye-control” literally means “control with eyes”. Sony’s naming is very confusing. Later, Sony also changed it and changed it to “ “Real-time eye focus”, the confusing meaning of the word helplessness has spread out. Now when it comes to “eye-controlled AF”, we have to distinguish whether it refers to “focusing with the eyes” or “focusing on the eyes”. This is a lot of trouble. , Sony’s biggest monstrous / squinting eyes. EOSR3 eye-controlled focusing accuracy, speed and other details are not known, it is not easy to evaluate, but it has been said that it can only be used when shooting still photos, it should be regarded as an icing on the cake. In addition. , EOS 3’s eye-controlled AF is realized by the way that the transmitter emits infrared light to the eyes, which is reflected by the iris and then received by the receiver. In addition to the problem of low accuracy and interference by glasses and contact lenses, In the past, I was questioned whether it was harmful to the eyes, and Canon never used the eyes again. Control AF. It remains to be seen whether EOSR3’s eye control will have these problems. 5. Three-proof, integrated vertical handle. Regardless of what you say, for EOSR3 and Z9 fuselages aimed at the Olympic Games, the triangular power and integrated vertical handle are necessary. Anyone who hangs a urine bag and connects a power bank is just a joke, and I don’t explain it. 6. How ugly…

The micro-single market in the past two years has been really hot, and there is a feeling that you sing and I will be on the stage, and blockbuster new phones one after another. Prior to this, Canon had been going to develop EOS R1, which caused a lot of restlessness in all parties. Nikon announced the development of Z9, and Sony directly released a1. Nowadays, Canon suddenly announced the development of R3. I think this move has achieved at least three effects: one is to give people a sense of surprise, and to create momentum in marketing. The second is to introduce black technology, such as true “eye-controlled focusing” and so on, and at the same time, pay tribute to the legendary camera EOS 3. The third is to hide the first-hand R1, on the one hand, leave a suspense, on the other hand, look at the products of other manufacturers and then shoot, trying to suppress other flagship models. So, the question is, why is the new machine called EOS R3 this time? The single-digit models of Canon’s SLR product line were named 1d, 5d, 6d, and 7d. Then the 3 series will become Canon’s new product line. We all know that the lower the number of Canon’s product numbers (1, 5, 6, 7), the higher the end of the camera. According to this principle, R3 should be a highly positioned model, at least higher than R5. In fact, in the history of Canon’s camera development, there was a camera named after the number 3. It was the legendary camera “EOS 3”. In 1998, it was released because of the blessings of many black technologies, which caused it in the photography industry at that time. sensation. In a sense, EOS R3 is a tribute to the classic legendary film camera EOS 3. It is a continuation and rebirth of feelings, a passionate collision between historical classics and the latest imaging technology. This is also the origin of the EOS R3 model. Back to the product parameters, how strong is the performance of EOS R3? I believe that the detailed parameters have been disclosed by major photography websites and self-media. Here I will briefly draw up the key points for everyone: the back-photo stacked CMOS continuous shooting speed has also reached 30 frames/sec. Eye tracking. Although the official performance parameters are very high. Long, but I think these three are the most meaningful. Back-illuminated stack type? Canon’s sudden big leap forward? If I remember correctly, this should be Canon’s first back-illuminated stacked CMOS. The continuous shooting speed of 30 frames per second indicates that it is a photographic field that requires high-speed continuous shooting, such as professional sports shooting and bird shooting. With such performance, it can establish its dominant position in the fields of sports, photojournalism, etc. It is believed that it can show its talents in this year’s Tokyo Olympics. Eye tracking? True eye-controlled focusing, the focus is right wherever the eyes look, and it feels very sci-fi when you think about it. The black technology of the film era 20 years ago is finally resurrected. Here, I need to explain. Don’t confuse the R3’s eye-controlled focusing with Sony’s real-time eye-controlled focusing. The latter, to be precise, is the human eye recognition focusing, which is similar to the R5, which can automatically recognize human eyes or animal eyes and focus. . The eye-controlled focusing technology can actually be traced back to 1992, and it is also a Canon product. Canon pioneered the eye-controlled autofocus selection function on EOS 5, which caused a sensation in the industry at that time. No, it’s the following “old antique”. In 1995, Canon launched an improved version of EOS 50E again, and the eye control function became more sensitive and practical. By 1998, the quasi-professional model EOS 3 was equipped with a wide-area eye-control autofocus selection function, improved the eye-control detection algorithm, and the upgraded 32-bit processor greatly improved the speed of eye-control focusing. In that era, eye-controlled focusing technology was one of Canon’s best black technologies. Most people don’t understand, how does the camera determine that the eyeball is moving and then focus? Schematic diagram of the principle of eye-controlled focusing Back then, Canon’s eye-controlled focusing technology was equipped with an infrared light-emitting diode on the eyepiece. After the light enters the human eye, it reflects on the retina, returns to the camera, passes through the SI lens, and then is projected to the eye-controlled BASIS sensor. Detector, so as to perceive the position where the eye is looking at and focus. As shown in FIG. According to a data provided by Canon, the eye control response speed of EOS 3 is 65 milliseconds, which can be said to be quite fast. Why was this black technology that bombed the sky afterwards, how was it sealed up? Because there are some disadvantages in actual use, if the user wears glasses, the accuracy of eye control will decrease. Also, when there is only a single subject in the picture, the focusing speed is very fast. Once there are more subjects and they are all moving, the accuracy will not work. In addition, if an eye-controlled focusing system is added near the viewfinder, the tightness of the body will be challenged and the waterproof level will be reduced. Today, this black technology is making a comeback, and along with the same digital “3” series cameras, Canon is going to smash the eye-controlled focusing technology to the end. I also believe that this time the Canon EOS R3 should be equipped with “full body” eye-controlled focusing. Whether it is the waterproof EVF viewfinder or the redesigned focus accuracy based on artificial intelligence algorithms, it will give us a stunning performance. Although R3 is good, don’t be greedy. Although it will be some time before R3 goes on sale, I have seen some photographers are already gearing up to buy it. R3 has a high positioning. Judging from the current data, it should be positioned in sports, wildlife, news and other photography subjects. At present, for most ordinary photography enthusiasts and photographers, the all-round professional camera R5 is the better choice at present. Canon EOS R5 has high pixels, good picture quality, excellent video performance, and comprehensive performance at the industry’s first-class level. It is a “bucket-type” camera with a balanced and high level of performance. In particular, the new firmware of R5 has strengthened the video shooting capabilities and added clog3 to further enhance the user experience. Moreover, the price of R5 has stabilized after the initial price increase, and players who like it can no longer wait and see, just start decisively.

First show your identity: once a Canon 6D user, now a Sony A7M3 user, a senior keyboard photographer. When I just saw the official announcement, I was suddenly excited: Canon finally has a back-photo stack, and finally the edge is up. But we are all back-photographing the stack, so the overheating of the video shouldn’t be a problem, right… (Crazy clearly shows that from the selling point of the main continuous shooting, this machine should not be against the Sony a1, it should be against the Sony A9 series. It does not use high pixels as the main product, indicating that it should not reach the 5000w pixel level of a1, and may not even reach the 4500w pixel level of R5. I guess it should be at the 3000w pixel level. 8K video may be hopeful Not big, I think it’s good to give a 4K120p. By the way, Canon’s mirrorless can provide Sony’s high frame rate mode with sound, sometimes sound is still very important. Eye-controlled focus resurrects this It’s a small surprise. I’ve never been in contact with film SLRs. I’ve only heard of EOS-3’s eye-controlled focusing in the legend. I’m looking forward to the performance after this official release. The selling point of the box machine is different, and some people complain about it. In the mirrorless era, it’s still so silly and thick. Some people need large batteries or battery redundancy to support productivity. However, judging from the pictures released so far, the warship’s nose is really ugly, too round, and there are no edges and lines at all. ……Although it is a Sony user, I really don’t want to see Sony dominate the mirrorless market. The monopoly will inevitably bring toothpaste. Whether it used to be a toothpaste factory, Canon or now occasionally blows up a toothpaste tube, there must be competition. , Manufacturers will release more attractive products. The advent of a1 has shown that Sony has been a bit unable to sit still, and Canon is gradually catching up. Finally, no matter how much I look forward to Canon’s future performance, I… .. No money to buy this flagship machine

Canon EOS R3 should not be delayed for too long, after all, the pressure is too great. In the past few years in China, Canon, a small company, wedding team, etc., was able to make money. Later, Sony succeeded in taking the lead with a higher picture quality and a smaller body. Now no one around me uses Canon to shoot videos! (Specifically referring to SLR and private micro. The newly released c500 and c300 in the past two years are still very useful.) I met two Canon ambassadors, and today I forwarded the R3 circle of friends at the same time.

R5 has almost squeezed the performance of the front-illuminated cmos, and finally changed to the back-illuminated. In terms of product positioning, Canon has not planned to directly compete with the a1 bucket machine, but first came out with a sports machine to complete the product line. With the addition of several rf telephotos to be released, it is a wave of sales before the Olympics. The main impact on the key camera is that Sony/Canon will be added when evaluating R6 and R3 in the future. If btw is named after R7, will there be R2 and R4 (scratch head)?

One sentence can be objectively summarized, Canon is anxious to show that although our fans have not said their identities, but we all tacitly agreed with each other, that is: the camera body, Canon has been far away from Sony. I have said many times that Sony has made a lot of money in the field of mobile phones, which has brought ample foundation for its accumulation. The consequence is that it can get rid of the two-generation CMOS speed and even turn all its peers into downstream. Because Sony is large, it can extend its tentacles to any industry by trial and error. This is a dimensionality reduction blow that Canon cannot resist. Every time a strong man breaks his wrist in history, he has to pay a heavy price, but no one knows which time he will go the right way. Last time it was ef bayonet and invincible rabbit, this time it was mirrorless, mobile phone and a1. r5r6 is a masterpiece in recent years, with both speed and picture quality. Being able to turn the bow at this speed to overcome problems, sum up experience and draw out the answer sheet is worthy of the identity of the industry giant, even so, it is necessary to rely on sub-fields such as video sampling rate for differentiated competition. So what answer sheet did a1 draw out next? The speed of 30 frames per second directly breaks the minimum limit of 26 videos, while maintaining the 50mp high pixel and the consistent top-level high-feeling and low-feeling latitude. At this time, 8k video is just a gift. Except for the price, there are no shortcomings. This is completely beyond the scope of Canon’s capabilities, what level is r3. High-sensitivity high-speed three defenses, the first two are already in conflict with pixels in common sense, what should I do with this configuration that should be provided for r1? What should Canon benchmark a1? I can only say that I hope there is a hole card.

As a user holding z6 and waiting for z9 to go on sale, I think it’s interesting to announce the R3 at this time. The full-frame, square camera may not be Sony’s A1. I personally think it’s a bit like benchmarking Nikon z9, which may also be for the Olympics. prepare? After all, there is no square machine for the full-frame mirrorless now… It’s reasonable, the more I look at it, the more it looks like, after all, if you benchmark Sony, there is no need to build a square machine, but I will definitely start with the z9 thing then, is it the number one? The time depends on whether there is any surplus on hand. The studio still needs a camera and video double-fixing machine. I originally prepared for the z7 2, but after seeing the z9, I decided to wait for the z9. After all, the z-mount is too fragrant.

No mention of 8K video at all, the resolution is probably about 20mp again. It is assumed that CMOS and a9/a9 II are at the same level. I hope the low-sensitivity dynamic range is not too bad.

Is it the evidence developed by Canon? Does Canon develop its own full-pixel dual-core focus? Since the release of the one-inch bottom product line, the cmos speed is very similar to the Sony products of the same generation; the g7x3 cmos is most likely Sony’s (because I don’t have a stone hammer and I’m too lazy to look for it). Simply put, the specifications are completely compatible with the black card. The same, but the sales of g3x, g5x, g7x, and g9x are not many, so the cost is too high for self-developed.

R5 overheating is manual castration. The external network has manual magic correction without overheating recording, a heat sink matter
I don’t have the money to buy this flagship-level machine, but I expect CANON to produce a decent one at 10,000 yuan, or the A7M4 will not come out.

I felt that my newly bought r6 was not fragrant when I watched the publicity, and then I looked at the price of the recent rf lens and purse. I’m already enough for my r6 24105usm. It will be much more expensive than a1, and deep learning and eye-controlled focusing have unlimited potential. The price is around fifty-eight thousand [thinking]
