Image quality

In terms of Image quality, Sony RX100 III, doesn’t give a tough fight to Canon G1X Mark III since both use different image sensors. However, G1X 3 with APS-C image sensor clearly catches the line, which is comparatively larger than the 1″ sensor used by Sony so we do expect much clear images with exceptional sharpness from Canon. Plus, the 24 MP effective resolution makes you obvious that one can get large print of the subjects as well compared to the 20MP of Sony.

AF system

We can say the time to flaunt with Canon G1X Mark III. Yes! because it features Dual Pixel CMOS AF system which you can call a magical stick in Speed and accuracy that significantly fortifies the potential of Live View Shooting of G1X 3. Actually, CMOS sensor in G1X III has two photodiodes per pixel (Total 40 million) and each pixel on the sensor performs both phase-difference detection autofocus and capture light. On the other hand, Phase-difference detection AF, enabling the cameras to achieve quick and easy auto focus. Moreover, the new Canon camera also features 49 AF points resulting in high precision AF at remarkable speed.

Nikon Sony RX100 III uses Contrast detect AF sensor only for quick and faster tracking of the desire subjects. Also, Sony carries only 25 AF points, can’t give you the wider coverage throughout the frame not as G1X Mark III.

Continuous shooting speed

Availing continuous shooting speed of 10fps, RX10 3 looks vibrant to capture all the actions occurring at the given time. Moreover, RX100 III incorporates an advanced mirror vibration control technology that remarkably helps the camera to support its speedy, continuous shooting capabilities without losing the image quality. On the other hand, g1x 3 also avails 9fps that is just a frame lesser compared to Sony.

Battery Life

Canon may have solid specifications inside but its battery just drained in around 200 shots only, whereas Sony RX100 III lets you capture 320 shots at a time.

Weather sealed

You could see a large difference in the price tag of these two cameras, but the Canon users would get the advantage of weather sealed camera along with the wonder package of specifications, which is Dust and water resistant ready for a variety of challenging shooting scenarios.


According to us, if price doesn’t matter then go with G1X Mark III – a very notable powershot camera from Canon comes with stunning specifications which gives you a flaunting moment of shooting while you are in the go. Sony RX100 III is gone behind due to its age. A cyber-shot compact camera has now its successors on the market with one step advanced specifications inside (Sony RX100 IV, Sony RX100 V)
