The new Sony alpha a7c is now the world's most compact full-frame camera

Sony has unveiled another potentially exciting new member of its alpha camera series. The a7c may be a full-frame mirrorless unit; however, its chassis measures only 4.9 x 2.8 x 2.2 inches (124.0 x 71.1 x 59.7mm), meaning it could be mistaken for an APS-C unit. It also features a classic-looking silver top-plate option and the OEM's updated LCD that flips to one side rather than upward.

The a7c has a 24.2MP Exmor R CMOS sensor and a BIONZ X image processor. It is rated for an ISO of up to 204800, as well as 15-stop dynamic range. Sony has also managed to pack 5-axis IBIS into the relatively tiny form-factor, which may help enhance its UHD 4K recording at up to 30 fps, which has a full pixel readout and a maximal 4:2:0 8-bit output. There is also FHD recording at up to 120 fps.

The new full-frame unit also supports S-Log2, S-Log3 and HLG formats. Being a Sony alpha, it also offers numerous in-house technologies, which in this case include Real-time Eye Auto-Focus (AF) and Real-Time Tracking. Sony has also introduced Animal Eye AF with the a7c, which as the name suggests is a new intelligent way to keep a subject in shot for that cute pet video.

In terms of interface, the Sony a7c's controls have been laid out much like those of the a6600. It also features both headphone and mic jacks to keep track of audio on the unit itself. Shoe-mounted mics may also benefit from a digital audio interface thanks to the new Multi-Interface Shoe.

The a7c's card slot is on the left-hand side, and it also features an HDMI Type-D port for external recorders, which may boost recordings up to 4:2:2 8-bit. Furthermore, its USB port is type C, and it supports dual-band Wi-Fi.

Sony has also introduced the new FE 28-60mm f/4-5.6 lens to go with the a7c. It weighs only 5.8 ounces, yet may have the range for many different photography genres. The OEM has priced it at US$1799 for a standalone unit, whereas the new FE lens has a recommended price of $499. It can be pre-ordered at retailers such as B&H Photo, which is also bundling it with the 28-60mm accessory for $2098.
