Super large aperture Lenovo K900 shooting evaluation | Ainongji - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

As a key product jointly launched by Lenovo and Intel, Lenovo K900 also uses Sony's 13 megapixel super aperture (F1.8) camera in camera selection. How can this lens be used in conjunction with Lenovo's own key "super camera"? Let's take a look at how the K900 prototype performs.

Let's take a look at the "Super Camera" interface designed by Lenovo:

The shooting interface is very simple. There is no complicated design.

Click the menu button in the lower left corner to see the options of basic settings, advanced settings and other settings.

The classification of each setting item is very clear, and users will not be confused by a large number of optional settings.

Click the extension lens of the super camera in the upper right corner.

Many functions of the super camera can be realized here.

On the lower right are the various real-time filters of the super camera.

That's the basic introduction of the super camera. Let's get to the point.

day

Although it was sunny on the day of shooting, there were still many dark clouds in the sky. K900 has no metering mode that can be adjusted, only the default matrix metering.

The daytime performance was pretty good.

Sharpness performance is OK, this is a 100% screenshot of the previous sample.

The matrix metering effect is also good, and the overall exposure of the sample is well controlled.

Many children's shoes have asked Xiaobian where this is. In fact, this is Shenzhen's Happy Coast. If you want to visit Shenzhen, you can also come here to have a look. The overall environment is quite emotional.

HDR

The HDR of K900 can be opened in the extended lens, But please note that as long as you use the extended lens, the sample will be reduced to 5 million pixels 。 Why shrink the proof sheet? In order to speed up the sample generation time, the larger the pixel, the longer the generation time. Reducing the sample pixels can also reduce the machine operation time and accelerate the sample generation time. Sony L35/36h also uses this technique to process samples when using additional shooting effects (such as HDR).

HDR is closed, and the focus of these two samples is on the building. Under such a high light ratio environment, the sky behind the building will become white due to overexposure.

After HDR is opened, the building details can be better displayed, and the cloud details behind are also richer.

The following four samples were taken by Lenovo K900 with HDR enabled:

Macro

K900 has good macro ability and natural tone. The large aperture of F1.8 is also easier to show the effect of shallow depth of field when shooting at macro. If you are not familiar with the effect of aperture on depth of field, you can go to the《 Science popularization: influence of aperture size on depth of field 》Go and have a look.

In addition, the small editor now has a "macro" mode in the extended lens.

This is taken after opening. The color will become very thick after opening.

Macro mode shooting. When macro mode is turned on, the color of the picture becomes too thick, which is not good for Xiao Bian. Moreover, after being turned on, it will not improve the shooting macro.

In fact, the original macro ability is not bad. Even shooting messy flowers and plants with large aperture and shallow depth of field is easy to highlight the main body.

Nightscape

ISO automatic, shooting in night view mode. Hmm... Actually, this one was not shot at the same time as the other three. The other three visual images of the same scene were not completely cleaned by the editor, so the lens glare would be a little serious. But even if the lens was completely cleaned like this, the glare would still exist.

However, the sharpness of the night scene sample is really poor. This is a 100% screenshot of the previous sample.

Shoot using the "dim light" mode of the extended camera. Note that as mentioned above, using the shooting mode in the extended camera will reduce the number of pixels to 5 million. In low light mode, the shutter time is extended to 1/8 second, so children's shoes with shaking hands need to pay attention.

When HDR mode is used for shooting, there will be more noise in HDR samples.

In fact, from the above pile of night scenes taken in different shooting modes, we can know that the best performance of Lenovo K900 when shooting night scenes is the samples taken in the night scene mode. But to turn on the night view mode, you need to click: Settings - Scene - Night View Mode to call out the night view mode. For some people who don't like the adjustment mode but just like "fool shooting", it will not be so friendly. In addition to the night view mode, the next is the weak light mode, and then the normal mode. HDR mode does not need to be enabled. There are too many noise points.

Filter

There are many real-time filters in the super camera. It is difficult for Xiaobian to list them completely, so he has to select several to test the effect.

"Star" filter, shooting a small computer desktop. In fact, this filter is to add some flash effects to the highlighted areas of the screen.

This is the original picture of Xiao Bian's desktop.

Kaleidoscope filter.

Axis Shift filter.

This is interesting. The "water wave" filter has a reflective water ripple filter at the bottom 1/3 of the screen. Pay attention to the water ripple at the bottom of the screen.

In addition, to my surprise, there is dust in this camera... One white one in the picture is that dust, fortunately it is not very big and it is not in the center

summary

Lenovo K900 performs well in the daytime, with good metering control and sharpness. HDR effect is very pleasing to the eye, and the effect is also good. The macro effect is also OK. Although the recent shooting distance is not very close, it is enough. In addition, the large aperture and shallow depth of field are easy to highlight the main body during macro shooting. As for the "macro" of the extended mode, it is unnecessary to open it. The night view is very clear. The best performance is the "night view mode", but it is troublesome to open this mode, followed by the "weak light" and then the normal mode. But on the whole, the night view performance of K900 is not very good, and the sharpness is very low, but as long as it is not magnified, it is still OK. There are many expansion lenses for different purposes in the super camera, which can also give people more choices. In addition, there are many built-in real-time filters. Some filters are very interesting, which is a good function.

If the super camera can put its scene mode on the shooting interface, it can be easily adjusted, so that it will have a better experience in shooting.
