50 million pixels for Canon EOS5DS, 5DR for hand.

IT 168 evaluation lead: 20 15 February, Canon officially launched 50.6 million effective pixels of 5DS and 5DR digital SLR. After seven years, I finally regained the title of "135 camera has the most pixels".

▲ Canon EOS 5DS, 5DS R

Basic introduction

Canon EOS 5DS and 5DS R were released on February 6th, 20 15, and officially released in June. Price comparison among Chinese mainland, Hongkong, China, USA and Japan;

In particular, 5DS and 5DR are not substitutes for 5D3, and they will be marketed together. Just like EOS- 1D and EOS- 1Ds before, since February of 20 15, Canon 5D series has also been divided into 5DS sub-series with high pixels.

product comparison

Canon 5DS and 5DS R

Photosensitive element: 5DS R cancels the function of low-pass filter to eliminate moire;

Nameplate of fuselage model: 5DS is written in gold, 5DS R is written in white with red "R";

Shoulder straps are provided randomly: 5DS is in gold, 5DS R is in white with red "R".

The relationship between Canon 5DS and 5DR is just like Nikon D800 and D800E. The suggested retail price of 5DS R without low-pass effect is about 1000 yuan. In the case of sufficient supply and little price fluctuation, 5DS R is definitely the first choice.

▲ Difference of low-pass filter

Considering that Nikon D8 10 and other products have completely canceled the low-pass filter, Canon's practice of releasing two versions at the same time is conservative. As for the two colors of the fuselage model nameplate, it may be to avoid profiteers' fraud.

Among many improvements, ET is most concerned with high-pixel RGB metering and UHS-I high-speed SD card, which is the biggest shortcoming of Canon 5D3 compared with Nikon D8x0.

In addition to sacrificing 3.5mm audio output in order to place USB 3.0 interface, the lack of "large area autofocus" and "lens distortion correction" is also a small regret.

Canon 5DS R and Nikon D8 10

Neng5dSR has many similarities with Nikon D8 10, such as low vibration reflector, electronic front curtain shutter, delayed shutter release option, timed photography/delayed short film shooting, etc. Nikon added the "sharpness" option to the optimized calibration of D8 10, and Canon also added the "fine detail" mode to the photo styles of 5DS and 5DR.

In addition to the pixel difference, the main advantage of Canon 5DR is the higher specification focusing and metering system, and the main advantage of Nikon D8 10 is the built-in flash and 1080 60p short film recording format.

Transparency test:

▲EOS 5DS f 1 1 ISO 100

Coupled with the previous evaluation of the 80 megapixel digital back, I felt this extreme detail clarity on the 35mm digital SLR for the first time! I have evaluated almost all heavyweight 35mm digital cameras in the past four years, and none of them can show all the details of Washington 1 USD. EOS 5DS did it. When this photo was enlarged to 100% on my computer, I thought I was looking at the scene with a magnifying glass. I think that after the pixel reaches 50 million, plus the decisive performance of Canon EOS 5DS for details, the pixel has changed from quantitative to qualitative.

High sensitivity test:

I turned off all noise reduction and all picture optimization. From ISO 100 to ISO 12800, the whole sensitivity was photographed.

From the picture, we can see that it is under ISO 400, and the picture is very clean and delicate, with no obvious changes.

At ISO 800, sharpness began to decline slightly. But the picture is still clean. The loss of clarity will not affect anything.

By ISO 1600, the noise of the picture began to increase, and the sharpness and details began to lose obviously. But overall, it is still within the acceptable range.

At the time of ISO 3200, the details and sharpness of the picture were seriously lost, and noise began to become obvious. This kind of image quality will have an impact if the output format is large and the quality is high.

Therefore, according to our standard, the image of EOS 5DS in ISO 800 is very good and can be used safely. At the time of ISO 1600, it still maintained a certain level of high image quality, and there was not much problem in using it. И o16000 is the highest sensitivity.

Opinions of all parties

@ A Zhuo's actual shooting experience

Because the fuselage appearance of 5DS and 5DS R is almost exactly the same as that of 5D3, there is no need to describe the feeling of grip and operation here. One day I didn't shoot a lot because of the weather in Beijing, but many improvements of this new machine made me very comfortable to use. For example, the second generation intelligent information display viewfinder, multiple cropping modes and brand-new automatic white balance all make shooting more handy. Of course, these new functions have not increased my learning burden, and they are basically available at any time.

5DS and 5DS R not only add the B-gate timer and timing shooting function on 7D2, but also can directly generate delayed video (first appeared on Canon SLR). You can get a creative photo without any accessories.

For the old users, the most gratifying thing about 5DS and 5DS R is that the original camera handle and wireless transmitter can be used in common, and there is no need to increase the extra cost. However, the design of giving up the 3.5mm audio output interface because of adding the USB 3.0 interface is still somewhat unpleasant, and live listening is very important for video shooting.

Faced with 50 million pixels, the most worrying thing is the memory card. Only about 600 RAW+JPG images can be saved in 32G space.

To 50 million pixels by @ Ningsixiaoxiao

Since this year, 35mm digital SLR has entered the era of 500 million pixels. If you round up again, it will be easy. ...

With the improvement of pixels, many people say that pixels are useless. Actually, I said something similar. But my premise is that if the average consumer's budget is limited, maybe 24 million pixels in 20 15 is enough. But for photographers in some professional fields, the higher the pixel, the better. Of course, if there is no shortage of money, the higher the better. After all, we can be invincible in pixels.

It's like finding a girlfriend and being beautiful, okay? Some people don't know, because they are beautiful and attractive. I'd say you can only lose silk all your life. Only those who dare to manage can marry the beauty queen. Because beauty is a good thing.

The same is true for high pixels. Some people say that high pixels are poor in high sensitivity, yes, but we can't waste high pixels because of high sensitivity. After all, you spend a lot of time using low sensitivity. If you have a high pursuit of the unparalleled details brought by 50 million pixels, you will naturally not care about the loss of high sense. What's more, if you compress the size of the picture later in the computer, you may have a good feeling.

Others say 50 million pixels, there must be too many lenses. In fact, this is not true at all. Why didn't anyone ask this when the 70D with 20.2 million pixels came out? Because it's only 20.2 million pixels per inch. If the 20.2 million Canon APS-C sensor is made in Quan Huafu, it can have 565,438+0.7 million pixels. When it comes to mobile phone cameras, it's even denser. So worrying is totally different.

Even if the lens can't perfectly support the improvement of pixels, the same lens, 50 million pixels is better than 40 million pixels.

So pixel height must be a good thing.

If you are from the mud pit family, you may be cynical again. Especially when you endured the pain for 36 million pixels, now you probably want to hit the wall. If you are a canon user, I think it must be very difficult to get on at this time, and you have to get on without making things difficult.

In this case, Mr. Ning also told everyone a word: buy early and enjoy early.

On dynamic range from @ETPHOTOS

In the dynamic range test of DxO, Canon products generally lag behind other manufacturers (products using Sony CMOS). Reflected in the actual shooting, Canon cameras usually have color noise in dark light, which will be more obvious after the later brightening operation.

Some people attribute this result to Canon's backward CMOS manufacturing process, but this statement is actually untenable. Photodiodes on CMOS are analog circuits, which can't be compared with high-frequency digital circuits such as CPU and GPU. Process improvement will certainly promote it, but a simple process gap will not bring such a big difference between the test results and the actual shooting. After communicating with people in the industry, we believe that the main reason for limiting Canon's dynamic range performance is ADC (Analog-to-Digital Conversion Circuit).

As early as 2007, Sony introduced CMOS with built-in ADC, which shortened CMOS→ADC→ image processor to CMOS→ image processor. The image signal is first denoised in CMOS, and the output of CMOS is digital signal instead of analog signal. After 20 10, almost all manufacturers such as Nikon and Pentax adopted CMOS built-in ADC scheme. Canon, on the other hand, still adopts independent ADC scheme until 5DS and 5DS R. What's more intriguing is that Canon has also introduced FPGA (Programmable Gate Circuit) as the front-end processing unit of DIGIC since 70D, which makes the image processing flow inside the camera more complicated.

The good news is that the dark light performance of Canon 5DS and 5DR has improved obviously. After the real shot sample is greatly brightened, there are no ugly color stripes in the past. Corresponding to Canon official website, "CMOS image sensor circuit is not easy to mix noise in the process of reading data, which makes the dynamic range of image data wide and the signal-to-noise ratio high".

▲ image processing flow of ▲5DS and 5DS R

Summary: The image data processing flow of Canon 5DS and 5DR may not be the most advanced, but it is obviously superior to previous Canon products in dynamic range, especially in dark light performance. Our test is still going on, and more samples will be released soon, so stay tuned.
