Retro Quan Huafu digital SLR turned out Nikon Df evaluation.

IT 168 Evaluation This evaluation brings you the retro full-frame digital SLR camera Nikon Df just released by Nikon. This camera has caused quite a stir recently. The stunt of retro Quan Huafu SLR made almost all photographers turn their attention to this camera, especially those old Nikon users, as if they saw that the old Nikon lens in their hands was about to glow with the dawn of the second spring.

Here we briefly summarize the Nikon Df camera, which can actually be regarded as the retro appearance of Nikon FM2, the core of Nikon D4, that is, the combination of16.25 million CMOS and the performance of Nikon D600. I believe everyone has been very interested in this camera. Below I will take you to take a close look at this retro full-frame digital SLR camera.

Purchase instructions:

To tell the truth, the appearance of this camera is really bright. In fact, excluding the price factor, I think this camera is very suitable for most young artists at present. But the price of this camera is really a bit high, so considering the current price of this camera, I think this camera is really only suitable for Nikon powder with very strong retro plot.

The new 50 1.8g lens is not ugly, but the optical quality is no different from the original 50 1.8G, and the purple edge is also serious at large aperture. Therefore, it is better for friends who have the ability to buy this camera to look for the manual lens in Nikon's mouth in the market. The original Nikon or Zeiss Leica will do. Anyway, Nikon DF is a machine suitable for slow shooting. Retro dial control and manual focusing can highlight the tonality of this camera.

At present, the stand-alone price of Nikon Df is 17800 yuan. Click to view details.

The appearance is extremely retro:

▲ Nikon Df

The overall appearance of Nikon DF is very retro, and the design draws on many Nikon classic film SLR. For example, Nikon's classic film SLR FM2.

▲ The back of this camera uses a 3-inch LCD screen with 920,000 pixels.

▲ Nikon Df

Nikon DF adopts a circular viewfinder that can only be used by Nikon's high-end professional SLR, which highlights the professionalism of this camera.

▲ Nikon Df

The arrangement and design of the back buttons are still not much different from the current digital SLR cameras. And from the overall design of the back of the camera, it is very similar to Nikon D800.

▲ Nikon Df

Speaking of Nikon Df, the biggest feature is the retro metal turntable on the top of the fuselage. This camera adopts the design of regression film SLR turntable, and there are sensitivity turntable and exposure compensation adjustment turntable on the left side of the top of the fuselage.

▲ Nikon Df

On the right side of the top of the fuselage are shutter dial, shutter and mode dial. This shutter dial adds a shutter speed adjustment mode of 1/3. The scales on all dials of Nikon Df are hollowed out, and there is also a dial lock for placing misoperation. Although humanized, the control efficiency is also reduced.

▲ Nikon Df

Before Nikon DF was released, there was a saying that this camera would cancel the shoulder screen. Although this will make this camera more original, its practicality will be greatly reduced. Fortunately, Nikon DF finally retained the shoulder screen, and the shoulder screen did not feel any contradiction on the fuselage. Among them, the number of photos taken by the shutter aperture and battery information can be displayed. All the information that needs to be displayed is basically displayed here, which is enough.

▲ Nikon Df

Nikon Df has designed a vertical dial wheel on the front of the fuselage, which can control an aperture and a shutter with the horizontal dial wheel on the back of the fuselage within m range (interchangeable function can be set in the menu).

▲ From top to bottom are USB interface, HDMI interface and accessory terminal interface.

▲ Nikon Df

Nikon Df's battery compartment is opened in a different way from other digital SLR cameras. Before opening the hatch cover, you need to turn the small switch of the battery compartment.

▲ Nikon Df

After opening the battery compartment, you can see the place where Nikon Df puts the battery and SD memory card. Nikon Df uses a battery of 1230mAh, so it can shoot normally all day.

Medium resolution:

Nikon DF uses the same16.25 megapixel Quan Huafu sensor as Nikon D4. As for this number of pixels, some people may think it is a little small, but I personally think it is enough. As far as the current situation is concerned, there is not much difference between16.25 million pixels and 24 million pixels in the resolution level. The real difference is an output size, which is not much different in actual use.

Let's take a look at the resolution of Nikon Df in the test. The Nikon Df used in this test is matched with the newly introduced 50mm 1.8G special edition lens, and the ISO 12233 standard card is still shot in the evaluation room environment.

▲ Center resolution test results

▲ Edge resolution test results

Through the test results, we can see that the optimal resolution of Nikon Df SLR can reach 2600 lines, which is normal for a sensor with 654.38+0.625 million pixels, and can basically be at a medium level in all digital SLR cameras at present.

▲ Interception position

▲ screenshot of the real shot sample.

Under the strict evaluation environment, we took the indoor proofs in the above picture with Nikon Df, and enlarged four partial screenshots by 100%. As can be seen from the enlarged detail map, the resolution performance of Nikon Df is the same as the objective test result, which is basically enough for daily use.

High sensitivity effect is good, and ISO3200 can be used:

▲ The red box is the interception position.

The common sensitivity range of Nikon DF is ISO 100 to ISO 12800, and it can be extended down to ISO50 and up to ISO204800. After testing the sensitivity of Nikon DF, we can clearly feel that using16.25 megapixel sensor is definitely a wise choice. Because this will bring less burden to the image processor and improve the image quality at high sensitivity.

▲ Noise reduction mode is not turned on.

We can see that in ISO3200, DF can still maintain a good image quality, and the details are well preserved. Even if it reaches ISO6400 and ISO 12800, the noise level is completely acceptable, and emergency use is no problem.

▲ Low noise reduction mode

▲ Standard noise reduction mode

▲ High noise reduction mode

At the same time, we also tested the sensitivity performance of Nikon Df in three noise reduction modes. From the results, the noise will be further suppressed after turning on noise reduction. In the high noise reduction mode, the number of noise in ISO25600 can be suppressed very little, but the same noise reduction will cause a lot of details loss. So overall, turning on the standard noise reduction mode is the most compromise.

The color is blue:

Let's look at the color cast of Nikon Df camera. In the color test, we set Nikon Df to automatic white balance mode to shoot standard color cards (the red box area in the above picture is the color test range), and finally analyze the test results with Imatest software.

▲ Nikon Df dispersion test results

The part surrounded by gray lines in the figure is the color gamut range of Nikon Df. The square color block in the test chart is the ideal color value, and the circular color block is the actual shooting value. As can be clearly seen from the above picture, in the automatic white balance mode, the color of Nikon Df machine is obviously blue, which is more suitable for taking photos with landscape themes.
