Canon EOS 90D evaluation of 32.5 megapixel mid-range SLR

When it comes to mid-range SLR, I believe many readers will be familiar with it. In general, the midrange model can provide balanced parameters, similar to the control experience of professional machines, and also has a user-friendly price, relatively portable body, which is the best choice for ordinary players to take photos in the pit.

Looking at the mid end SLR market, Canon's two digit models can be said to be very popular. Previously, 60D, 70D, 80D, etc. had good sales. In August this year, Canon officially released a new mid-range SLR—— EOS 90D Let's take a look at the shooting performance of this new machine.

01 New height of mid end SLR pixel

"High pixel+high speed" is Canon's new generation APS-C frame camera The subject of. Both the EOS 90D evaluated this time and the EOS M6 Mark II released at the same time have about 32.5 million effective pixels, and both support the continuous shooting speed of more than 10 focus shots per second, giving consideration to excellent image quality and powerful capture.

In terms of video, 90D supports up to 4K 30P recording without cutting, which makes wide-angle lens more usable, and also further improves the definition of the video itself. In addition, with the help of the microphone and headphone jack equipped on the body, this mid-range SLR can also perform well in video audio reception and monitoring, and its overall shooting ability is more comprehensive.

The new machine continues the "easy to use and efficient" characteristics of Canon's new generation of SLR in terms of controllability. The full-featured touch flip screen, shoulder screen, and rich key paddles are standard configurations. In addition, this is Canon's first midrange model equipped with focus selection paddles, bringing a professional SLR experience comparable to that of a professional SLR. In addition to the price of 7649 yuan, the new machine has a very high cost performance.

Considering the performance of image quality, focusing, control and other aspects, the author gave this camera 8.3 points. Now let's take a look at the appearance and detail design——

02 More professional fuselage control

Overall, 90D is still the style of Canon's mid end SLR. From the front, it is not different from the previous 80D. After all, the appearance and body design of this series have already become mature.

Thanks to the wide handle and frosted body coating, the 90D has a good grip, which is also a consistent advantage of the SLR model. After all, comfortable use experience is very important for photographers who hold photography for a long time.

Looking at the back of the body, this SLR is equipped with a rotating screen and supports full function touch operation. At the same time, 90D is also equipped with an optical viewfinder with a field rate of about 100%, which can be said to be very sincere.

In terms of details, the biggest highlight of this camera is the addition of a focus selection lever, which greatly improves the efficiency of focusing operation. It is worth mentioning that the 90D is the first Canon mid end SLR equipped with a focus lever. Previously, only the 1D, 5D and 7D series of professional fuselage would have this configuration.

In terms of control layout, the 90D is equipped with a set top shoulder screen, surrounded by single function buttons, which can be adjusted quickly with the front and rear dual paddles. The operation experience of the whole machine is very professional. The specific key position of the new machine is basically the same as that of the previous mid end SLR, and you old Canon users must also be very familiar with it.

The 90D still uses a single SD card slot design and provides a set-top flash, which is also standard for Canon's mid-range SLR models. Since the storage stability of the existing SD card has been greatly upgraded compared with the previous one, a single SD card slot can actually meet the needs of many high-speed photography.

This SLR is equipped with five interfaces, including HDMI USB、 The earphone, microphone and remote control shutter cable jacks are all distributed on the same side of the body, so the scalability of photography and video is good.

The 90D has a very strong endurance. The new aircraft still uses Canon LP-E6N or LP-E6 batteries (with 5D, 6D, 7D, 80D EOS R and other series are common), but further optimization has been made in terms of power consumption. The full battery life of optical shooting is about 1860, and screen shooting is also about 510. There is no pressure to shoot for a long time.

In general, although there is no obvious change in the appearance design of the 90D, it has brought considerable upgrades in the optical viewfinder, control and endurance. The overall configuration has even exceeded some professional camera products on the market. Next is the specific objective test——

Note: All test materials in this article were shot by EOS 90D with EF-S 18-135mm f/3.5-5.6 IS USM socket.

03 Excellent picture and video quality

The EOS 90D has about 32.5 million effective pixels, which is also the highest level of APS-C frame pixels at present. Let's take a look at the imaging quality of the new sensor:

First look at the details. From the live photos, we can see that this new high pixel APS-C frame sensor does not disappoint us. It has a very solid imaging effect, and even after 100% magnification, it still has rich details and textures.

High pixels also mean more post clipping space. 90D can output pictures with a resolution of 6960 × 4640 at the highest. It doesn't matter if the shooting is too hasty in the early stage. In the later stage, you can completely cut for secondary composition, which is one of the biggest advantages of high pixels.

We have 100% enlarged display of the area in the three small red boxes in the figure

The pixels have gone up, and many readers are worried about whether the noise control ability of this camera will decline. Then we will test the noise suppression ability of the new machine:

As far as the test results are concerned, 90D has brought a leap in pixels, but at the same time its noise control ability has not collapsed, ISO 1600 starts to show slight noise. Even under the high sensitivity of ISO 6400, photos can provide rich details and textures. Generally speaking, they are available in the range of ISO 100~6400.

We conduct tolerance tests on the areas in the two small red boxes respectively after over exposure and under exposure

In addition to analytical power and noise control performance, 90D tolerance is also the focus of attention. The author also tested its tolerance performance——

In terms of tolerance, the author chose the environment with large light ratio for over exposure and under exposure shooting, and restored to the normal exposure level through later stage. In case of overexposure and darkening, it can be seen that the 90D photo has basically lost its usability after two levels of overexposure (although the details are retained, the problem of color deviation is serious), which is also true Digital camera The common fault of.

In the underexposure and brightening area, we can see that the space of 90D is very large in the later period, and there is no obvious color deviation while retaining details. Therefore, the author suggests that when shooting scenes with large light ratio (including sunrise, sunset, large backlight, etc.

It is worth mentioning that 90D can shoot up to 4K 30P video without cutting, which is also Canon's first midrange model supporting 4K. The feature of no cutting allows the wide-angle lens to play more advantages. As for the clarity, the author has taken full size screenshots of its 4K sample:

From the perspective of the magnification effect of the screenshots of the live video, the quality of the 90D video is still satisfactory, and the appearance of the magnified details is relatively solid. In addition, this camera provides a microphone jack and headphone port, which can also provide a more professional shooting experience for video users. In general, this is an all-purpose SLR that combines photography and video.

04 Focus and continuous shooting experience is brilliant

Focus after seeing the imaging ability. As a SLR, optical shooting is the core working mode of 90D. It is equipped with a 45 point full cross focusing system, and an RGB+IR photometric system of about 220000 pixels has been added. From the author's personal shooting experience, 90D can bring accurate speed and precision performance whether it is single focusing or focusing.

In real-time shooting, 90D It will switch to a full pixel dual core focusing system with 88% focus coverage. Let's see the focusing experience of real-time shooting——

As far as the actual shooting effect is concerned, the 90D real-time shooting and focusing speed is fast enough, that is, when using the telephoto lens to shoot, it still has a fast and smooth experience when switching the focal plane.

It is worth noting that under real-time shooting, this SLR supports automatic focusing for eye detection, and can continuously focus whether the person moves or turns back, greatly simplifying the shooting experience, which is very worthy of recognition.

In addition, the 90D eye recognition function is also available when shooting videos. The video can also provide a stable facial focusing ability, which is very suitable for vlog recording, personal hosting program recording and other topics, and is practical enough.

Then watch the continuous shooting. 90D has a maximum continuous shooting speed of about 10 shots per second in focus mode. Let's see the continuous shooting effect——

The author snapped a group of swimming black swans in the zoo. It can be seen that the 90D continuous shooting function is very practical for moving objects. The 10/s continuous shooting speed can capture multiple moments of object movement, providing more space for later film selection.

In addition to fast continuous shooting, 90D's focusing performance is also very stable. The author used AI SERVO mode in continuous shooting, and the photos obtained can be accurately focused. In terms of focusing speed, continuous shooting speed, focusing accuracy, etc., 90D has brought outstanding performance, which can meet various needs such as static recording, portrait capturing, and motion tracking.

05 Sample and evaluation summary

At the end of the evaluation, let's take a look at the performance of this camera. The author took the EOS 90D (with EF-S 18-135mm f/3.5-5.6 IS USM sliphead) to the zoo for a simple trial experience. The samples were straight out in JPG format, and only simple cutting and exposure adjustment were made——

Focus segment: 100mm Aperture: F4.5 Shutter: 1/1000s Sensitivity: ISO 800

Focus segment: 135mm Aperture: F5.6 Shutter: 1/250s Sensitivity: ISO 250

Focus segment: 95mm Aperture: F8.0 Shutter: 1/160s Sensitivity: ISO 800

Focus segment: 109mm Aperture: F5.6 Shutter: 1/200s Sensitivity: ISO 1600

Focus segment: 135mm Aperture: F5.6 Shutter: 1/250s Sensitivity: ISO 1250

Focus segment: 92mm Aperture: F5.6 Shutter: 1/200s Sensitivity: ISO 2000

In the previous test, we have known the excellent quality of 90D in terms of analytical power and noise control. From the actual sample, the new camera also has bright and natural color performance, which is also the strength of Canon camera. With beautiful colors and fine and solid photo texture, the appearance of this camera is quite satisfactory to the author.

Focus segment: 135mm Aperture: F5.6 Shutter: 1/2000s Sensitivity: ISO 640

Focus segment: 135mm Aperture: F8.0 Shutter: 1/320s Sensitivity: ISO 320

Focus segment: 122mm Aperture: F8.0 Shutter: 1/200s Sensitivity: ISO 100

Focus segment: 18mm Aperture: F8.0 Shutter: 1/100s Sensitivity: ISO 100

Focus segment: 135mm Aperture: F5.6 Shutter: 1/320s Sensitivity: ISO 400

Focus segment: 128mm Aperture: F5.6 Shutter: 1/320s Sensitivity: ISO 1000

As far as the evaluation results are concerned, As a mid end SLR, the EOS 90D is more than just a mid end SLR. Up to 32.5 million effective pixels, 10 focus shots per second, new focus paddles, non cutting 4K 30P videos, and the endurance of 1800 videos when fully charged... Some specifications of 90D have even exceeded their own high-end full-size products. Whether it is imaging effect or manipulation, this camera has brought the experience of "following the crime".

We often say that a camera cannot be perfect, but it is difficult for the author to pick out the shortcomings of 90D. If you insist, the continuous shooting duration of this SLR is a little short. After all, under the premise of excellent continuous shooting speed and focusing accuracy, the continuous shooting duration of about 58 JPGs is easy to feel "more than enough". Of course, for a mid-range model with 32.5 million pixels and a price of less than 8000 yuan, the capture performance is good enough.

It has to be said that 90D is an epoch-making product. Starting from this camera (and EOS M6 Mark II), APS-C has officially entered the 30 million pixel mark. Meanwhile, 90D The domestic listing price of M6 Mark II is 7649 yuan and 5749 yuan respectively, which is also the first batch The listing price is less than 10000 yuan 30 megapixel fuselage. If you have high requirements for pixels, snapshots and controls, then Canon EOS 90D It will be a cost-effective choice.
