Video Quality
The Asus Zenfone 6 is a clear winner when it comes to video quality, as it is able to record in 4K resolution compared to the 1080p resolution of the Honor 20 Pro and OnePlus 7 Pro. Additionally, the Zenfone 6 has the advantage of a larger main sensor compared to the smaller front-facing sensors of the other two phones, resulting in greater dynamic range. None of the phones have optical image stabilization on the front, so there is a similar amount of shake when walking.
Audio Quality
The audio quality of the Asus Zenfone 6, Honor 20 Pro and OnePlus 7 Pro is comparable, with no major differences between them. All three phones have a microphone that is capable of capturing clear audio, and the sound quality is generally good.
Selfies
When it comes to taking selfies, the Asus Zenfone 6 has an advantage over the other two phones. The highlights are much better controlled with the Zenfone 6, while the Honor 20 Pro and OnePlus 7 Pro tend to add a lot of contrast to the mask. Furthermore, the Zenfone 6 has the added benefit of being able to use its ultra-wide camera on the front, which is much wider than the other two phones.
Portrait Mode
The portrait mode on the front of all three devices is quite impressive, with the OnePlus 7 Pro having the edge in terms of edge detection. The Honor 20 Pro and ASUS Zenfone 6 offer a more natural look, while the OnePlus 7 Pro offers a crisper finish.
Rear Cameras
When it comes to the rear cameras, all three devices offer a 48 megapixel primary camera, as well as an ultra wide lens. The Honor 20 Pro and OnePlus 7 Pro have an additional 3x telephoto lens, with the Honor 20 Pro also offering a dedicated macro camera. All three devices can take 4K video at 60 frames per second, with the OnePlus 7 Pro having the edge in terms of color processing and definition.
Video Stabilization
All three devices offer impressive video stabilization, with the OnePlus 7 Pro being particularly impressive. However, the Honor 20 Pro has the edge when it comes to zooming, as the OnePlus 7 Pro does not allow you to use its 3x zoom lens in video, and the ASUS Zenfone 6 does not have a zoom lens at all. The OnePlus 7 Pro also does not allow you to use the ultra wide lens for video, although this may be a feature that is added in a future software update.
ASUS Zenfone 6 vs Honor 20 Pro vs OnePlus 7 Pro Camera Test Comparison
The ASUS Zenfone 6, Honor 20 Pro and OnePlus 7 Pro are all equipped with impressive cameras. To compare their performance, a camera test was conducted to determine which device produces the best results.
Ultra Wide Angle
When it comes to ultra wide angle shots, the ASUS Zenfone 6 has a slight edge over the Honor 20 Pro. At 4K resolution, the Zenfone produces a striking result. Lowering the resolution to 1080p further improves the quality of the image, with the Zenfone taking the lead.
Slow Motion
The OnePlus 7 Pro is the clear winner when it comes to slow motion footage. It can record at 240 frames per second, while the Zenfone and OnePlus can record at 480 frames per second. The Honor 20 Pro can do short bursts of 960 frames per second, but this is achieved through software interpolation, making it not quite as good as the other two devices.
Night Time Shots
In theory, the Honor 20 Pro should excel in night time shots due to its 1.4 aperture. When zooming in on a bus, the text on the back is easily distinguishable and the colors look great on the OnePlus. The Zenfone looks a little soft, while the OnePlus is noticeably noisy. However, when cropping in, the clock at the top is most readable on the Honor.
Rear Camera Comparison
The ASUS Zenfone 6 has the most impressive rear camera of the three phones, with its ability to capture DSLR-quality images even in low light conditions. The Honor 20 Pro is the least impressive of the three, with its photos losing definition in low light. However, the Honor 20 Pro does have the advantage of a wide aperture, which comes into its own in very low light conditions. The OnePlus 7 Pro has the best dynamic range and clarity in low light photos, but its telephoto lens does not perform as well in low light.
Front Camera Comparison
When it comes to front cameras, the ASUS Zenfone 6 pulls ahead of the other two phones. Its selfies are of almost DSLR quality, even in low light. The Honor 20 Pro is the most affected by fading light, while the OnePlus 7 Pro has a bright flash which is an area of relative weakness for the ASUS Zenfone 6.
Night Mode Photos
When taking night mode photos, the ASUS Zenfone 6 has a realistic dark, moody vibe, while the Honor 20 Pro and OnePlus 7 Pro focus on brightening the image. The OnePlus 7 Pro has the cleanest and sharpest image, while the Honor 20 Pro’s wide aperture gives it an advantage in very low light conditions. The ASUS Zenfone 6 can use its telephoto lens to losslessly zoom in, but it does not perform as well in low light.
HDR Mode
The HDR mode of the ASUS Zenfone 6, Honor 20 Pro, and OnePlus 7 Pro were tested in order to compare how each phone managed to make identical subjects look different. It was observed that the Honor had a slightly warmer tone which added to the overall contrast and texture of the shot. The general was that for simple daytime photography, any of the three phones would suffice.
Portrait Mode
The portrait mode of the three phones was also tested. It was observed that the OnePlus 7 Pro zoomed in for portrait shots, thus requiring the user to step back further for the shot. The colors of the OnePlus 7 Pro were also noted to be balanced.
Ultra Wide Lens
The ultra wide lens of each phone was also tested. It was observed that the ASUS Zenfone 6 had the most expansive lens with a 125 degree field of view. The dynamic range of all three phones was also noted to be satisfactory.
Telephoto Lens
The telephoto lens of the Honor 20 Pro and OnePlus 7 Pro were tested. It was observed that the ASUS Zenfone 6 had no such lens, thus making it difficult to capture objects further away. The Honor 20 Pro was noted to have a dedicated 2 megapixel macro camera.
