Sony RX100 Series Comparison (I, II, III, IV and V)

Articles from:

Specification Sony RX100 I Sony RX100 II Sony RX100 III Sony RX100 IV Sony RX100 V
As expected, the latest generation Sony RX100 V obviously does have much richer feature-set and specifications compared to its predecessors. It has a superior Stacked CMOS sensor with excellent image quality that surpasses all the previous generation RX100 cameras, faster Bionz X processor with a front-end LSI capable of handling up to 24 fps shooting speed, 315 phase-detection autofocus points, 4K video recording at up to 30 fps and very respectable slow motion video recording capability up to 960 fps. It can handle shutter speeds of up to 1/32000 sec, has a very nice 2.36M electronic viewfinder (EVF), incredibly fast autofocus and a few other nice extras, such as anti distortion shutter and ability to set minimum shutter speed when shooting with Auto ISO enabled.

Git 2 Gitup Action Camera Review


Some of the exciting features of GIT2 are 16 megapixels IMX206 Sony Exmor image sensor and Novatek NTK96660 chip. Combination of the two allow camera to create true 16mp images in RAW or Jpeg, and more importantly video at 1080p 60 FPS together with 2K @30FPS and 2880×2160 @24fps. Camera supports external microphone and memory card up to 64gb.

Like previous model, this one is compatible with wrist controller which allows remote control of the camera via radio frequency. Additionally camera has a built in WiFi, so you can connect to it via your smartphone. It got 30-meter water-proof housing (like GoPro Hero). Its retail price is around 159$, though some Chinese retailers sell it for a bit less.

How to use the RAW file on Git2?

Convert RAW file into DNG for Action Camera GIT2?

(For Windows only – as of 2016/05)
How to use the RAW file on Git2?

Thanks to the DashCamTalk member @the-force who helped us to provide this tool and script.

First turn on the RAW option in the Photo mode settings. It will take much more time to save the .JPG and .RAW file after enabled the RAW option.

Convert the RAW file to DNG

RAW2DNG tool:

This tool can support for both 16:9 and 4:3 raw images. Just drag and drop the Raw files in the program, select proper image format and click on convert.

Correct the DNG file

There is much red in original DNG file, below tool is for correcting black level, white level and white balance.

To use the correction tool, simply drag and drop the dng files (also multiple files at once) on the fix_levels.bat. Please note that the exiftool.exe has to be in the same folder as the batch file. The dng files will then be corrected and replaced automatically.

The correcting tool is not perfect, maybe some other Git2 users can help to improve it.

Below fixing DNG script is provided by @Nigel.

exiftool -BlackLevel=200 -WhiteLevel=4095 -AsShotNeutral=”0.5100 1 0.6400″ %1 -overwrite_original
