Comprehensive evaluation of high-end DC heavyweight Samsung smart camera EX2F

IT 168 Evaluation Although the market of SLR and single battery is hot at present, high-end DC, which combines professionalism and portability, is still an irreplaceable important product. So Canon released G 1 X, Sony released RX 100, and Samsung also released the sequel after the highly acclaimed EX 1? EX2F .

EX2F appearance review

Samsung EX2F adopts11.7 inch sensor, and its appearance is very similar to EX 1. There is a retro feeling, and the camera switch is still designed with Samsung blue indicator light, which looks very comfortable.

▲EX2F front

The big letters F 1.4 can be seen on the front of the fuselage, indicating that the maximum aperture of the Samsung EX2F can reach F 1.4. This is very useful for shooting in dark environment. Many people will think of the background blur effect when they see the large aperture of F 1.4. In fact, for such a small-area sensor camera, the background blur effect can only be reflected when shooting macro, and it is impossible to get satisfactory blur effect when shooting portraits with it.

▲EX2F back

The layout on the back of EX2F is relatively regular, and almost all commonly used parameters can be adjusted by Fn key. The overall control efficiency is not low, which is also a basic standard as a professional DC.

▲EX2F Side and top bottom

EX2F is small, but the prominent lens makes it difficult for EX2F to fit into a jacket pocket. The design of the EX2F top double turntable is quite pleasing, and there is also a small flash at the top, which is necessary to fill the light.

▲ Card bin and battery bin

EX2F has a card compartment and a battery compartment at the bottom. As a camera with 654.38+02.4 million pixels, it is enough to shoot for one day with an SD card above 4G.

▲EX2F battery

In terms of power, the battery of EX2F is 1050mAh. After the author's test, it is no problem to take 400 photos. If it's not a long trip, there's no need to buy batteries.

The resolution of EX2F is quite satisfactory.

As a professional-grade DC camera, the resolution performance will be the most concerned by users. We tested the resolution of EX2F by ISO 12233 resolution standard.

▲ Resolution standard

Through testing, we got the resolution data of EX2F:

▲ Samsung EX2F resolution test results

The resolution of Samsung EX2F is basically around 2400 lines, which is quite satisfactory as a12 megapixel camera. Let's take a look at the actual shooting effect:

▲ Samsung EX2F real shot effect

We use Samsung EX2F to shoot standard sample scenes, and use ISO 100 and F5.6 aperture to shoot. Judging from the actual shooting effect, the details of EX2F are not well preserved, and the graininess of the picture is also relatively heavy.

On the whole, the resolution of Samsung EX2F is average, which does not achieve the expected effect in the author's mind. But the EX2F I got is an engineering prototype, depending on the retail version of the product.

Samsung EX2F High Sensitivity and Color Performance Test

Samsung EX2F's high sensitivity performance is average.

We use EX2F to shoot standard samples at various speeds, and then slice at the same position at 100%. Through these slices, we can see the high sensitivity level of Samsung EX2F:

Through 100% slicing, we can see that Samsung EX2F began to show obvious detail loss in ISO 400, and the detail loss in ISO 800 has become unacceptable. At the same time, since ISO 80, the image of Samsung EX2F has obvious sharpening marks. I suggest that you don't use sensitivity exceeding ISO 400. In view of the fact that I got the engineering prototype this time, I hope the retail version of the product can be better.

Samsung EX2F color test

As a digital camera, color expression is particularly important, which is related to the photographer's adjustment of color temperature for different themes to achieve the best results.

▲ Samsung EX2F color test results

The left picture above is the color representation of manual white balance. From the test results, the manual white balance color temperature is accurate, and the overall color is red and blue, which is very suitable for shooting scenery. The picture on the right shows the color performance of automatic white balance, and we find that the color is slightly blue when performing automatic white balance. Similarly, red and blue are stronger.

Lens deformation and light loss test

As a DC with integrated lens design, the quality of the lens is also an important indicator of the camera. First, let's take a look at the lens distortion of Samsung EX2F.

▲ wide-angle barrel distortion

At the wide-angle end of EX2F, the barrel distortion is still obvious, so you should pay attention when shooting buildings. If you are good at using barrel distortion, you can take more impactful photos.

▲ telephoto end pincushion distortion

At the telephoto end of EX2F, we can see the horizontal and vertical effects. Although the pincushion distortion can be seen carefully, it is well suppressed.

Next let's look at the four corners of EX2F. The loss of light is also called dark corner, which is very popular among many photographers. Of course, most photographers still think that dark corners are the result of uneven light reception.

▲ Wide-angle optical loss effect

▲ Loss of light effect at telephoto end

As can be seen from the above figure, there is almost no dark corner at the wide-angle end after the telephoto end F3.9, and there is almost no dark corner from F2.7 It seems that the dark corner control of Samsung EX2F is still very good.

In fact, at present, many digital cameras will add more optimization to the processed image, so that the image becomes undistorted and there is no dark corner in the software. This is also the development trend of DC integrated with fuselage and lens at present.

Samsung EX2F Real Shooting Effect and Evaluation Summary

Generally speaking, the solid workmanship and beautiful appearance of Samsung EX2F add a lot to it, but it has no outstanding performance on the screen. Especially at present, both Canon G 1 X and Sony RX 100 are taking the route of large sensors, and only the EX2F of11.7 inch sensor is inevitably pushed down. Therefore, Samsung EX2F should pay more attention to ordinary home users. Samsung EX2F with WIFI sharing function is undoubtedly more attractive to home users, after all, this camera can be sent directly to Weibo.

Purchase suggestion: Samsung EX2F has a good image quality and a good control feel. At the same time, the solid body makes you confident when shooting. Flip screen and WIFI sharing function will undoubtedly make your shooting and sharing more convenient. If you are going to buy a simple and reliable camera for general home shooting, then Samsung EX2F can complete the task well. At present, Samsung EX2F has not been listed yet, so I suggest that it is more appropriate to buy it at around 2500 yuan.
