Sony Alpha 7C - Full size for your pocket


Windows Master

25 views

The Sony Alpha 7C turned out to be a powerful DSLM with a full-frame sensor in an unusually compact housing. The image quality is excellent, even at higher ISO values. Only the auto focus weakens in low light. It is a shame that the menus cannot be operated by touch on the swiveling display. The wide range of lenses guarantees high flexibility.

Sony Alpha 7C Review: The slimmer 35mm camera
From the outside, the Sony Alpha 7C resembles a camera from the compact 6000 series with an APS-C sensor; Inside, however, the finest full-format technology from the 7 series is slumbering. This combination makes the camera currently the smallest and lightest full-frame DSLM with an integrated image stabilizer. It weighs just over 500 grams and is therefore only slightly heavier than the Alpha 6600, but noticeably 150 grams lighter than the Alpha 7 III. Compared to its APS-C sister, it is only half a centimeter larger in width and height, and the depth is almost identical.

The relationship between the controls cannot be denied. The arrangement of buttons, switches and wheels only differs to a limited extent. Vloggers and YouTube stars will be happy about the 3-inch touch display that can be folded out to the side and swiveled 180 degrees. However, we miss a touch menu with a modern, clear structure.

As an alternative to the screen, there is a just 0.39 inch viewfinder with sufficiently sharp 2.36 million pixels. It comes from the Alpha 6600 and is equipped with a magnification factor of 0.59.

All connections are located under the cover on the left side of the case: 3.5 mm jack for microphone and headphones, USB-C, Micro-HDMI and a UHS-II card slot. Unfortunately, a double SD slot is missing here. For this you get Sony's innovative digital audio interface in the accessory shoe of the Alpha 7C. Thanks to the NP-FZ100 battery with 2,280 mAh, the Alpha 7C only runs out of breath after more than 1,300 shots.

Accessories are a good keyword. Sony knows how to play its trump cards in this area. Over 200 different optics with E-bayonet (full format and APS-C) are currently available. Thanks to the crop function, all lenses can be used at any time.


Sony Alpha 7C: Saturated picture with little noise
The interior of the Alpha 7C offers tried and tested and some revised components. The 24 MP sensor (with 6,000 x 4,000 pixels) comes from the Alpha 7 III and does a great job. The image quality hardly differs from the photo quality of the big sister, which is definitely a positive thing. Up to and including ISO 1,600, the values of the Alpha 7C are just under 1,900 of 2,400 theoretically possible line pairs per image height; very impressive.

Beyond this mark, the values only fall below 1,800 line pairs, even up to ISO 12,800. The Sony DSLM shows fine details just as well and with consistently high values of over 90 percent. Overall, this is an excellent performance.

We can rate the noise behavior similarly well. Subtle interfering pixels only appear at ISO 3,200. In low light, the DSLM still delivers clear images. Printed images are still usable even at ISO 12,800. For example, if you don't want to turn up the light sensitivity so high at dusk, you can switch on the powerful 5-axis image stabilizer as an alternative.


Sony Alpha 7C Autofocus is in focus
Sony doesn't compromise on autofocus. Like the Alpha 7 III, the Alpha 7C also uses 693 phase and 425 contrast AF points with a coverage of 93 percent of the sensor area. In the test it focuses comparatively quickly; only in low light does the DSLM take it easy. The Sony manages fast photo series with up to ten frames per second with a maximum length of around 250 JPEGs. The shutter speed is 1/4,000s, other cameras can do that better. But real-time eye recognition and real-time tracking have received a slight improvement. The videographers are also happy about these two functions.

 

Sony Alpha 7C Advantages:

  • Uncompromisingly compact housing
  • Excellent picture quality
  • Large range of lenses

Sony Alpha 7C Disadvantage:

  • Carrier auto focus in low light
  • No touch menus
  • Only one SD card slot
