If you want to open up the hierarchy between smartphones, it may be that in 2024, the most effective way in addition to the processor will still be the configuration of the camera function. In March last year, we were impressed by the Find X6 Pro released by OPPO, not only because of its restraint in image and shadow tuning, but more importantly, because the Find X6 Pro kicked off the prelude to the hardware armament of telephoto lenses.
The Find X6 Pro left us impressed in terms of focal length selection and imaging style, but less than a year later, OPPO officially launched the latest flagship model of the Find series, the OPPO Find X7 Ultra.
OPPO Find X7 Ultra相机核心参数：
- 广角主摄(1x):LYT900.50MP,f/1.8.23mm 1.0"-Type,1.6μm, Multi-directional PDAF, Laser AF, OIS
- 潜望长焦（3x，原生2.7×）：IMX890；50 MP，f/2.6, 65mm，1/1.56"，1.0µm，2.8x optical zoom，multi-directional PDAF，OIS
- 潜望长焦（6x）：IMX858，50 MP，f/4.3，135mm，6x optical zoom，multi-directional PDAF，OIS
- 超广角(0.6x):LYT600,50 MP,f/2.0,14mm,123° 1/2"
From the parameters, it can be seen that the hardware configuration of the OPPO Find X7 Ultra this time is quite outrageous, especially in addition to maintaining the one-inch main camera of the image flagship, after tasting the sweetness of the telephoto lens, the dual periscope lenses are directly arranged, and the actual shooting performance is expected.
We also got the OPPO Find X7 Ultra the day before the launch, and walked 30,000 steps in Hong Kong in one day to actually see how well this phone's camera function performs.

Compared with the previous generation of the Oppo Find X6 Pro, the biggest change in the Find X7 Ultra this time is of course the hardware configuration of the dual periscope lenses. Although the previous generation Find X6 Pro also has the same 6x telephoto shooting capability, it is actually achieved by cropping the 3x lens and optimizing it through algorithms, which is theoretically not a true optical lens.
This time, the Find X7 Ultra's 4 lenses are solid optical imaging, bringing 14mm ultra-wide angle, 23mm wide angle, 65mm and 135mm dual telephoto, and also taking advantage of the cropping advantage of the one-inch outsole to obtain a 44mm 2x standard lens focal length.
The feeling of space compression brought by the 6x telephoto lens
Let's first take a look at my favorite 6x telephoto lens for this shooting, I believe that for photography enthusiasts, although the previous generation Find X6 Pro can achieve digital 6x imaging, the actual effect is still quite different from that of an optical lens.
Let's take Hong Kong's popular attraction "Kennedy Town Seascape" as an example, and we want to shoot a shot of the seascape connecting the sea across the street. In fact, the Internet celebrity photo was taken by holding the mobile phone directly into the barbed wire gap of the basketball court for framing (left in the picture above). However, if we use a conventional 3X focal length lens, not only will the focal length be worse and the sense of spatial compression will not be enough, but we may also shoot the edge of the barbed wire.

And if you switch the lens from 3x to 6x, that is, from 65mm to 135mm direct focal length doubled, you will find that the framing effect is completely different, not only the composition of the distant seascape is larger, but also the sense of space compression is stronger, which is the biggest benefit of the mobile phone with a telephoto lens.

To change the distance of the scene, "Monster Building" is also a popular scene in Hong Kong street photography, and it is also one of the filming locations of the "Transformers" movie. Using a 135mm focal length 6x telephoto lens, we can easily take photos with a strong sense of spatial compression from a distance, compressing the streets, pedestrians and vehicles in front of us, and residential buildings in the distance into the same spatial plane, bringing a stunning effect.

In fact, one of the main reasons why Hong Kong was chosen to test the Find X7 Ultra's telephoto lens is that it is a very suitable city for telephoto shooting. Because of the dense space and many buildings in urban buildings, the sense of space compression achieved by using a telephoto lens is incomparable to that of standard lenses and wide-angle lenses. And it turns out that the two telephoto lenses I used the most in this shoot were also the Find X7 Ultra.
A better image quality option for 3x telephoto lenses
Compared to the 135mm telephoto compression of urban space brought by the 6x, the Find X7 Ultra uses a 3x lens this time because the 1/1.56-inch sensor area is still much larger than the 1/2.51-inch of the 6x lens, plus a larger aperture brings better light transmission. The actual image quality performance will be better than that of the 6x, so in some scenes where the image quality is more demanding, the 3x periscope telephoto has become a better choice.
For example, when shooting night photos, although both periscope telephoto lenses support OIS optical image stabilization, due to the low ambient light, we need a large sensor and a large aperture to achieve more light inlet in, resulting in better detailed images. That's why I prioritize using 3x telephoto when shooting at night to ensure better results.

I believe that if you look closely at the shooting parameters of this photo, you will find a problem. The Find X7 Ultra's 3x telephoto lens has a 65mm focal length, but when it comes to actual shooting, it shows 72mm. The answer is that when shooting a 3x telephoto frame with the Find X7 Ultra's default camera app, the stabilization function will be turned on to partially crop the frame, and the final focal length will be 72mm. And if you want to get a lossless focal length, you can use the "Master" mode in the camera app.

Switching to the daytime scene, we can intuitively see the actual image quality performance of the Find X7 Ultra's 3x lens because of the better light conditions. By magnifying the sample at 100% to observe the details, we can see that the advertisements and text on the dingding car of the main body of the picture are very finely restored, and the overall picture details are quite good, especially the highlight part has no obvious chromatic aberration, and the imaging effect is very stable.

After switching between the two telephoto lenses of the Find X7 Ultra frequently, you will find that the image quality of the 3x telephoto lens is indeed better than that of the 6x. So the advice we have here is that if you want a focal length advantage, better space compression, and longer shooting distance, then the Find X7 Ultra's 6x lens is fully usable and competent, and if you want to achieve more detailed imaging on top of the telephoto, switching to a 3x lens is a safer option.
Exaggerated visuals with a 0.6x ultra-wide-angle lens
When shooting in megacities such as Hong Kong and Tokyo, the ultra-wide angle is one of the most useful angles of view as a telephoto lens. But unlike telephoto lenses, which compress space, ultra-wide angles achieve a more striking effect by exaggerating perspective and capturing more information.

Let's take the simplest example, which is the shooting of "Monster Mansion". This scene is no stranger to photography enthusiasts, but if you want to shoot the dense buildings in the Monster Building, it is not enough to use the camera's default main camera, and you may even have to lower your phone flat on the ground to capture more details of the building. However, if you switch the camera to an ultra-wide angle, you will suddenly feel like you are taking advantage of the exaggerated perspective effect of the photo.

Let's take another scene as an example, when shooting a spiral staircase, even though we can use the main camera to bring more extreme image quality. However, in the framing, you will find that the spiral staircase is not fully included in the frame, and the effect will immediately make a difference when you switch to an ultra-wide-angle lens in time.

The same is true in this photo, this six-story detached house stands on the side of the street for some reason. It can also be seen that steel structural supports are also made on the side to prevent the building from tilting. But in a small street environment, if you want to take a complete picture of this building, you have to switch the camera to 0.6x ultra-wide angle, and add the element of the shopkeeper at the door as the finishing touch, and a good street photo is easily born.
1x 1x 1-inch image quality for the main camera
Another big highlight of the Find X7 Ultra's full focal length this time is the CMOS of the main camera with a 1-inch outsole. Compared to the IMX989 sensor used in the previous generation Find X6 Pro, although it is also a one-inch CMOS. However, this time, the Find X7 Ultra is equipped with Sony's LYT900, which directly upgrades the sensor process from 40nm to 22nm in the previous generation. In addition, the area of a single pixel has also increased from 0.8um to 1.6μm in the previous generation, which may achieve better performance in image quality.
Find X7 Ultra拍摄RAW照片大小接近30MB
Let's take one of the most extreme examples, we directly use the Find X7 Ultra's main camera to turn on the master mode to shoot RAW photos, you can see that the size of a single photo has come to 39MB, and DNG format will also record more rich picture information for us to post-grad.

We then imported the DNG photo into Photoshop, and with a simple curve processing with CameraRaw, we got a well-exposed photo with rich colors. And pay attention to the adjustment parameters of the photo here, you can find that we have pulled the highlights and shadows to 100% of the limit position, and then the photo is still usable, although there will be some color noise when zoomed in, but the use of CameraRaw's AI noise reduction function can perfectly deal with the noise of this DNG format. In the actual post-production experience, the Find X7 Ultra's RAW photo tolerance performance is very exaggerated!

Change to a cat shot with the Find X7 Ultra main camera, zoom in and take a 100% closer look at the details, you can clearly see that the details of the cat's whiskers, hair and eyes are restored quite well. And because of the large one-inch sensor and the large aperture of F1.8, the overall background blur of the photo is also very natural, and the bokeh effect is more realistic than that simulated by the software.

Another thing I really like about the Find X7 Ultra's 23mm main camera is that it's very responsive. In addition to the reason for the optimization of the software, I think it should also be related to the higher process used by this Sony LYT900, and the overall photography is smooth. There is almost no delay in taking photos, and even the response to continuous shutter presses is very fast. The advantage is that it can be used with the 23mm focal length of classic street photography to achieve very accurate capture.
In the two photos above, for example, when I saw the car, I judged that its color and design were perfect for this scene, but by this time it was already preparing to turn and drive away. I took out my phone and unlocked it for shooting and pressed the shutter continuously, and I got these two snapshots. That's the advantage of the camera's responsiveness, and if a little bit of delay occurs, the photo is just missed.

Last but not least, the Find X7 Ultra is the main camera's Night mode experience, and as we mentioned above, we recommend using a 3x telephoto lens in low light conditions for better night image quality. Also due to the larger size of the sensor, the one-inch LYT900 in night mode is also more capable of exerting its strength.
Combined with the optical image stabilization of the lens, the success rate of night shooting is very high, even in handheld situations, and the overall performance of the Find X7 Ultra's night mode algorithm is still quite good, especially the restoration of the strong highlight of neon lights, which also makes Hong Kong's cyberpunk feel instantly full.

Experience Summary:
Shooting at full focal length seemed like an unlikely wish on a mobile phone many years ago, and it was a complex project both in terms of hardware quality and camera size. And with the improvement of sensor technology and the improvement of design, it finally got an end on OPPO's Find series. Find X7 Ultra's dual periscope telephoto lens this time further broadens the experience of mobile phone telephoto lens shooting, none of the four optical lenses are used in a single number, and the consumer experience is that no matter what the scene, as long as you take out your mobile phone at any time, you can choose a suitable lens for shooting, and you don't have to think about which sensor is a meaningless topic like a decoration.
After shooting nearly 1,000 photos in a day, I was also very impressed with the Find X7 Ultra: the fast response, the full-focal length experience, the Hasselblad tone and even the exaggerated RAW photo tolerance, which is still very attractive for a photography enthusiast.
