This is the fourth generation of the Sony cyber shot RX 100. This camera has improved performance, new features and excellent image quality as compared to the other Sony cyber shot RX 100.

The Sony RX 100 is a compact camera which is very user friendly.  Its new features include a high frame rate slow motion video mode, 16 fps continuous burst shoot and 4K video capture.

The technical information about this camera includes a processor by BIONZ-X; a 1.0”-type 20.1 megapixel image sensor which is different in design and is superior to its predecessors. The sensor is CMOS and is back illuminated and comes with a stacked design which consists of the DRAM memory and A/D converters which are beneath the light sensitive interface. These improvements are responsible for 4K video capturing, noise reduction and a swift 1/32000 second electronic shutter function. The differences in jello effect or rolling shutter reduction can be easily noticed when taking full high definition videos at 60 p and when taking still images using the electronic shutter.

The image sensor and processor of this model produce a decent ISO, which is similar to that of the RX 100 III. In default setting, it gives an IOS of 125- 12800. It also gives one the option to change the lower IS range to 80/100 .the multi frame noise reduction function of this camera allows for noise reduction for almost static objects.

The performance in terms of the burst capture has tremendously been improved. This model can handle up to 5.5 frames per second in standard shooting, as compared to the RX100 III which only handles up to 2.3 frames per second. When the speed priority continuous mode is enables, one can take up to 16 frames per second.

The lens has a 2.9x optical zoon lens. The maximum aperture is of f1/8 when in a wide angle and in a telephoto, it is at f2.8.  It has a focal range of 24-70 mm with its 35 mm lens. This model is also designed with a seven blade aperture iris, a built-in neutral density filter which works both automatically and manually and a Zeiss T coating.

The lens also consists of a steady shot optical image stabilization which is useful when taking shots of still images. The intelligent active steady shot stabilization plus the electronic compensation come in handy when shooting a movie.

Sony RX100 IV is equipped with contrast-detection autofocus technology. In the telephoto position, the minimum focusing distance is at 30 cm while at wide angles it is at 5cm. the most notable addition in the focusing of this camera is the expanded flexible spot mode. The other modes included are the centre, small, large, medium or wide autofocus modes. One can also use the continuous, single or direct manual focus modes as well as the fly-by-wire and fully manually autofocus.

The viewfinder of the camera is carefully added to bring more versatility to the camera. When it is raised, the camera will automatically power itself on. The rear element of the view finder can be pulled backwards so as to lock it in position.  The viewfinder has a 0.59x magnification, 20 mm eye-point and 100% coverage.

On its rear side, there is a 3.0 inch LCD panel with 4:3 aspect ratios. The monitor has a 1,228,800 dot count, a sunny weather mode and a brightness adjustment control.  The monitor comes mounted on an articulation mechanism which is more favorable when using he camera in a fixed position. When taking selfie photos, an upward tilt at an angle of 180 degrees is possible while a downward tilt of 45 degrees allows for overhead shooting.

The exposure modes of this camera are determined by use of centre-weighted, multi segment or spot metering modes.  The shutter speed is of 1/32,000 seconds and of 30 to 1/2000 seconds for electronic and mechanical shutters respectively. The developments in this model include a new high frame rate capture and a single auto mode which is on the mode dial.

If one needs more lighting during a shoot, a built-in flash is available which works at between 0.4 and 10.2 meters at a wide angle and at 0.4 to 6.5 meters at telephoto with the auto ISO sensitivity.

When shooting a movie the Sony RX100 IV offers one a wide choice of high frame rates.  While on the NTSC/ PAL mode one can either opt for the 1824 by 1026 pixels at 240/250 fps, 1676 by 566 pixels at 480/500 fps both of quality priority and a two second clip length or the 1136 by 384 pixels at 480/500 fps and 800 by 270 pixels at 960/1000 fps both of shoot time priority and  four second clip quality.

The wireless connectivity includes NFC transfers and wifi which allow for file transfers and remote control using iOS or an android device.  For a wired connectivity, there is a micro HDMI port for video output and a mini USB 2.0 port for connections to a device. The USB port is multi terminal and it also supports a wired remote control and tethered remote shooting from a Mac or windows computer.

The storage unit is a single slot which is compatible with a secure digital or a memory stick duo cards.  It also works well with SDXC, SDHC and UHS-I SD cards and pro duo, pro HG MS duo and pro duo high speed cards.  A 64 GB or larger card is usually ideal.

The camera is powered by a rechargeable NP-BX1 lithium ion battery and it lasts for up to  280 shots while using the LCD screen and 230 shots on the electronic viewfinder.

The camera has a dimension of 4.0 by 2.3 by 1.6 inches and weighs 295 grams.

Unlike its predecessors this new generation has an improved performance with a fast autofocus; a great burst speed with a deep buffer; a high ISO noise level which is better than its rival competitors; a high quality resolution which will give images a lot of details when taken in good lighting conditions; high quality 4K video output with an uncompressed HDMI and a fast HFR video. Not forgetting the amazing pocket -friendly design.

The limitations of the camera include an over-processed look for JPEG images at a higher IOS, the 24-70 mm lens can be quite limiting and it does give much of the telephoto reach.
