Nikon Unveils Z6 III with World’s First Partially Stacked CMOS Sensor at ₹2,47,990

Nikon has recently launched the Z6 III in India, featuring a 24.5-megapixel partially stacked CMOS sensor. This release marks a significant advancement in camera technology, distinguishing it from its predecessors and higher-end models. The camera is priced at ₹2,47,990 for the body only.

The Z6 III’s sensor architecture is unique, with components arranged as bars at the top and bottom of the pixel area, rather than across the entire sensor. This partially stacked design enhances processing speeds up to 3.5 times faster than the Z6 II’s traditional BSI CMOS sensor, leading to notable improvements in continuous shooting, autofocus, video frame rates, and rolling shutter effects.

In terms of viewfinder, the Z6 III features an exceptionally bright electronic viewfinder (EVF) capable of up to 4,000 nits, enhancing visibility in various lighting conditions. Video capabilities are also a highlight, with the camera supporting 6K RAW recording at up to 60fps and 4K RAW at up to 120fps. Nikon reports a 20% increase in autofocus speed compared to the Z6 II, along with extended sensitivity down to -10EV for better low-light performance. The ISO range reaches up to 51,200 for videos and 64,000 for photos, accommodating detailed imaging in dim conditions.

The Z6 III includes an advanced in-camera Vibration Reduction (VR) system, achieving an 8.0-stop stabilization. This system also features focus point VR, reducing blurring around the edges and aiding in subject framing. The camera is built with robust materials, combining Sereebo P series carbon fibre and magnesium alloy, and is designed to withstand challenging environments. It offers dust and moisture sealing and can operate at temperatures as low as -10 degrees Celsius.

Set to be available by the end of June 2024, the Nikon Z6 III will be sold across Nikon outlets in India. This camera, with its innovative sensor design and advanced features, aims to attract both professional photographers and enthusiasts seeking high performance.

How Canon, Sony and Nikon are fighting Deep Fake Images

With fake images and videos becoming more convincing everyday (like the Rashmika Mandanna fake video), tech giants have increased their monitoring to combat that menace. But now it is not only the tech giants, but camera manufacturers that are joining this fight by developing technology that will embed digital signatures in their cameras with new technology that can verify the authenticity of photos. Sony, Nikon and Canon are working on embedding digital signatures in their cameras that will act as the proof of origin and the integrity of the images shot by them reports Nikkei Asia.

The digital signatures are believed to contain information such as the date, time, location, and the name of the photographer who has shot the image. The manufacturers believe that this will restrict tampering and help the photographers and viewers to identify the credibility of the work. Nikon is expected to offer this feature in its mirrorless cameras, while Sony and Canon are expected to offer it in their professional line-up as well.

How does it work?

If you are wondering how does this work? Then the three manufacturers have agreed on creating a global standard for digital signatures, which will be made compatible with a web-based tool called Verify. This tool has been launched by an alliance of global news organisations, technology companies, and camera makers, will allow anyone to check the credentials of an image for free. Once the online tool runs through the image, it will display the relevant information if an image has a digital signature. If the image has been altered by AI, then the tool will flag it as having “No Content Credentials”.

Google, Intel doing their bit

Google, the biggest search engine globally is also doing their bit to help this fight. They have released a tool that adds invisible digital watermarks to AI-generated pictures, which can be detected by another tool. Intel has developed technology that can analyse the skin colour changes of subjects in images, which indicate the blood flow under their skin, and use that to determine the image’s authenticity. 

The Challenge?

The biggest challenge though seems to be the user journey where they will have to use these tools to verify the images and authenticity. Whether a user undertakes that journey remains to be seen. But it is clear that a tool/technology like this is much needed at this point with the increase of deep fake images and videos on a rise. 

Sony is expected to release this technology by 2024 as per reports and Canon is expected to make it available later this year. Currently this embedding is expected to be available only for images, but reports suggests that Sony and Canon are considering adding the feature to videos, although under development.
