Lightweight and balanced entry full-frame mirrorless single Sony A7C review

   After many rumors, Sony’s latest generation of full-frame mirrorless cameras changed from A5 to A7C, and the new product name was finally fixed to A7C, and Before the release of this product, in fact, the most rumors about this product were the size of the APS-C format camera. In many cases, the new smaller size would give people the illusion of Sony A6xxx, but after actually getting it in hand , It is indeed a full-frame body, so my title uses the APS-C volume full-frame core to describe this body. Even so, the overall configuration of Sony Alpha7C is not bad at all. So whether this product can meet your needs, let me take a look at the overall performance of this machine!

   Sony Alpha7C

   Sony Alpha7C has approximately 24.2 million effective pixels full-frame back-illuminated ExmorR™ CMOS image sensor and BIONZX™ image processor, and has 15 levels of wide dynamic range. And the Sony Alpha7C still has a 5-axis anti-shake function, and can also be hand-held to shoot clear and stable images in low light and other environments. In terms of focusing, the Alpha7C’s 693-point focal plane phase detection focusing system can cover about 93% of the image area, and has 425 contrast detection focus points, providing a wide, fast and accurate autofocus performance, which can quickly lock the subject. Out of focus, accurate and fast focusing can be achieved even in complex environments. And in AF/AE tracking mode to achieve high-speed continuous shooting up to 10fps;

In addition, Alpha7C supports HDR and S-Log/S-Gamut profile, SQ mode, high-speed FHD shooting at 120fps and other professional video functions. And in video shooting, the real-time eye focus function is also applicable.

  Sony Alpha7C front

  The new Alpha7C provides silver and black body color options. This time I got the silver version. On the front of the fuselage, the Sony Alpha7C adopts a black and silver two-tone design, and the handle position also adopts a new leather design. The feel of the fuselage is actually more like the feel of the Sony Alpha7 series, and the blessing of the full-frame sensor allows This machine looks more pleasing to the eye, perhaps because the previous APS-C sensor was too small!

   Sony Alpha7C back

  Alpha7C’s body size is only about 124.0mmx71.1mmx59.7mm, and its weight is only about 509g. Its size and weight are similar to those of APS-C format cameras. It is about 1% heavier than the Alpha6600 camera.

  Sony Alpha7C side

   The design changes on the back of the fuselage are quite obvious, except that most of the buttons are still the same as the A6XXX. The biggest change is the use of a side-turning screen design, which looks like a machine released in 2020. All adopt the design of side-turning screen.

   But unfortunately, the screen specification of Sony Alpha7 does not seem to have been upgraded this time. It also does not support full touch operation. It only supports touch focus, and the menu is not compatible. Sony Alpha7SIII also uses a brand-new design, which is a little regrettable.

   Sony Alpha7C Body interface

   In terms of body interface, Sony Alpha7C adopts a brand new design. Due to the larger battery and side-turning screen, Sony Alpha7C provides a single SD in the body interface The card slot, miniHDMI, Type-C data interface, headphone jack, microphone jack, the overall number is still a conventional design.

   Sony Alpha7C top

   Although the Sony Alpha7C has the size of the APS-C frame, the appearance design is more like the fusion of the A6XXX and A7 series. The top design is very There is a sense of line, the right button of the fuselage only provides the shooting mode dial and the exposure compensation dial, except for the video recording button, the power switch lever and the shutter button. The overall design idea is the same as the A6XXX series.

   Sony Alpha7C adopted With the NP-FZ100 battery

   battery, the Sony Alpha7C uses a rechargeable NP-FZ100 battery with a capacity of 2280mAh, which is the same as the previous Sony Alpha7RIV and Sony Alpha7SIII. It can be used for shooting with the viewfinder. 680 photos, screen viewfinder shooting can take about 740 shots; this battery life is sufficient for most daily life scenes, and Sony Alpha7C supports USB power supply, even in the case of insufficient power can also use USB power supply Continue shooting.

   In terms of video specifications, Sony Alpha7C provides 4K30p and 1080120p video shooting capabilities. As for why the shooting parameters of higher specifications are not given, I guess it should consider the positioning of the machine and the small size of the body The heat dissipation is the starting point, because this camera may be the cheapest product in Sony’s full-frame mirrorless camera, and 4k30p is completely sufficient for users who use this machine for video shooting.

   Sensitivity Test

   The native sensitivity range of Sony Alpha7C is ISO100-51200, which can be expanded down to ISO50 and up to ISO204800. It uses 24.2 million effective pixels The full-frame CMOS sensor has the same pixels as the Sony Alpha7III, but I am not sure whether this machine is the sensor of the Sony Alpha7III, so let’s take a look at the real sensitivity of this machine!

Lightweight and balanced entry full-frame mirrorless single Sony A7C review

  From the test chart We can see that the high-sensitivity performance of Sony Alpha7C is still good. Before ISO3200, the picture has no obvious noise; after ISO12800, the noise in the picture increases and a small range of color noise appears in the picture. In the end, despite the highest sensitivity of ISO51200, Certain details can still be seen. Generally speaking, if you look at the big picture, the image quality before ISO6400 is quite usable. This performance is actually similar to the previous Sony Alpha7III.

  Dynamic Range Test

   When I tested the dynamic range of the Sony Alpha7III, I felt that its overall performance was quite good. In the dynamic range test of the Sony Alpha7C, its Is it the same as the Sony Alpha7III? Here I used the RAW format to adjust the exposure and converted it to TIFF. When performing a screenshot display, when the screen has a color cast, the subsequent different exposure values ​​are no longer displayed.

  Through actual shooting, we can see that the detail retention of Sony Alpha7C at -5EV is still quite good, but There has been too serious color cast, and the color retained at -4EV is relatively more. The +3EV highlight part has been unable to restore the phenomenon, but the overall performance is still OK, in fact, the overall performance is basically the same as the Sony Alpha7III.

  FE28-60mm kit resolution test

  Sony FE28-60mmF4-5.6 is a kit lens released with this Sony Alpha7C. In this era of 2020, resolution should not be a big problem, and the aperture value of this lens is not particularly large, so I am personally optimistic in terms of image quality, sharpness and details. Let’s take a look at the performance of this lens at both 28mm and 60mm resolutions!

First of all, at the 28mm end, the aperture is fully opened and continues to f/16. The image quality performance is quite good in both the center and the edge. When the aperture is reduced to f/22, the sharpness of the picture has a certain quality decline, but the contrast is good. There is not much change, and it is in a highly available state.

At the 60mm end, the starting aperture of the maximum aperture is f/5.6, and the minimum aperture is f/32. The overall performance is actually equivalent to the 28mm end, and the previous gear at the minimum aperture shows very good sharpness and contrast. But when this lens is at the minimum f/32 aperture, the effect of diffraction on the image quality is still relatively large. On the whole, there are basically no problems when shooting with this lens, which fully meets the needs of daily use.

  Real shot samples

   In the sample shots, I used Sony Alpha7C to release the lens FE28-60mmF4-5.6 and FE85mmF1.8. , I have selected some samples here, all of which are original size samples, and interested friends can download and view the original images. Some samples have undergone simple post-grading.

   Evaluation Summary

   The biggest highlight of Sony Alpha7C is its compact size and portability. In fact, there is not much to say about the overall configuration. , As always, continued Sony’s high-spec configuration. I think the biggest upgrade point with Sony Alpha7III is mainly focused on the volume, video focus and photo focus, flip screen, video recording unlimited and other aspects, and in other aspects, Sony Alpha7III Obviously it is better than Sony Alpha7C, so in this view, Sony Alpha7C is more like a sincere reform to satisfy entry-level consumer users and users who are decorating photos and videos. How do you say the machine is a good machine, but The current price of 12,499 yuan per unit may have to persuade some users who are interested in this machine, or let these users buy Sony Alpha7III.
