The UMIDIGI Z Pro comes with a dual-lens camera, each camera uses a 13MP Sony IMX 258 sensor, one is a monochrome one and one is a Bayer one. Sony IMX258 sensors is 1/3.06" in size and features 1.12-micron size pixels. This dual camera setup allows the Umidigi Z Pro to enhance image quality, provide users with a monochrome shooting mode and allows the camera to achieve a DSLR level Bokeh in portrait mode. If this setup sounds familiar, it's because the LG G6 also comes with a dual-lens camera with IMX 258 sensor, however, the G6 has two bayer sensors and one of its cameras is an ultra-wide angle lens. This is also the same sensor used in the Allview X4 Soul, Oppo A57, Asus ZenFone Pegasus 3s. I wasn't that impressed with its image quality and low-light performance, at least no on those phones that I've mentioned.
The most noticeable advantage that this dual-lens camera offers is the ability to produce image with a very shallow depth of field effect. It actually mimics the same background blur effect that you get when shooting with a large-sensor camera and very fast aperture lens.
From the video that I've seen, the Umidigi Z Pro can simulate the effect of aperture ranging from F0.6 to F11. This works the same way it works in Vivo V5 Plus, but the V5 Plus has a range starting from F0.95 up to F16. So the if I am not mistaken, the UMIDIGI Z Pro can simulate the effect with even more prominent background blur effect. You can even apply this effect after capturing the image. This is my favorite features in DSLRs and why a few years back I've bought my Nikon D3100 DSLR with a fast 50mm f/1.8 lens. The Bokeh was just out of this world. Of course a simulated Bokeh isn't as accurate as its optical equivalent, but most people obviously don't shoot with this type of phone professionally, so it's still a very useful feature that many people will enjoy playing with.
The UMI Z Pro can also capture 3D images, which you can capture and then rotate them to see the 3D effect. It's like having the ability to move slightly from inside the image, cool stuff. The other features which I mentioned earlier is being able to capture a monochrome image. This isn't an unsaturated image of the color one, but true black and white images taken with the monochrome sensor, so it will have better contrast and better grayscale definition for a more striking and more beautiful B&W image.
Here, take a look at this video that showcase those features.
So the dual-lens camera brings some really nice features. Not that we haven't seen that before. The Huawei P9, Huawei P10 Plus, LG V20, Huawei Mate 9, all feature the same configuration with two cameras, one with a color sensor and second one with a monochrome one, but some have different sensors and different lens apertures. This dual-lens camera setup become really popular and will continued to be offered in mid-tire smartphone in 2017. These are features that aren't gimmicky, but built upon features that exist in more advanced cameras, features that professional photographers use to produce more creative and artistic shots. So now you can also enjoy those in your UMIDIGI Z Pro smartphone.
