New Delhi, Oct 30: Japanese major Nikon, which is celebrating 100 years in business this year, has unveiled its high-end “Nikon D850” — the first full-frame DSLR to earn a perfect score of 100 from the independent rating website DxOMark on both colour and dynamic range coming from the sensor.

The FX-format (full-frame) camera has an impressive 45.7MP sensor (up from its successor D810’s 36.3MP) with a native ISO sensitivity range of 64-25,600 and an upgraded 153-point autofocus system.

The device has seven frames per second (7fps) with continuous autofocusing (AF) which can be upgraded to 9fps with an additional battery grip.

Priced at Rs 254,950 (body only) and Rs 299,950 with the AF-S NIKKOR 24-120mm f/4G ED VR lens, let us see what this mid-range model in Nikon’s full-frame DSLR camera line-up and successor to D810 has to offer to photo enthusiasts.

Design: The body design of the D850 is similar to the earlier D810, but this time, Nikon has done away with the built-in flash — keeping in mind the needs of professional photographers.

The D850 is undoubtedly one of the company’s fastest-shooting DSLRs. The camera comes with a touch-enabled, 3.2 inch diagonal tilting LCD with 2,359K dots.

The weather-sealed magnesium alloy body is resistant to dust and moisture.

The camera weighs 915 gms with a dimension of 146 x 124 x 79mm. Nikon has designed back-side illuminated (BSI) full-frame image sensor with no optical low-pass filter.

Sensor: The D850 has Nikon’s first-ever BSI full-frame image sensor (35.9 mm x 23.9 mm) with no optical low-pass filter which will improve the low-light performance and peripheral image quality.

The BSI CMOS sensor delivers superior image quality when compared to traditional CMOS sensors. The D850 offer the lowest base ISO (ISO 64) of any DSLR or mirrorless cameras.

Video shooting: The camera can shoot videos in full-frame 4K UHD with NIKKOR wide-angle lenses as well as full high-definition (HD), slow-motion video recording of up to 120fps.

Perfect for multimedia shooting, the D850 supports 4K videography and 8K time-lapse movie production with silent interval timer photography as slow as 0.5 seconds.

Videographers can easily fine-tune colour, exposure and brightness that is reflected in white blown-out areas with Nikon’s “Flat” Picture Control, all without any hassle.

Card Slot: The camera has two card slots — one XQD card and the other Secure Digital (SD) card.

Pros: Lowest base ISO, high-resolution and sharp details, new silent shooting mode, large viewfinder, tilt-angle touchscreen LCD, proven AF system, good battery life and 4K UHD video shooting.

Cons: No built-in flash, Wi-Fi and Bluetooth connection lags.

Final Take: The D850 is probably the most well-rounded, full-frame DSLR camera from Nikon after Canon launched its 50 MPI (EOS 5DS) a few months back.

We, however, think Nikon has a slight edge when it comes to image quality.

The flexible shooting position and more focus points are helpful if you are covering fast-action games like football, hockey and badminton.

The continuous shooting mode is really fast and flawless with low sound. A small in-built flash could have make it much more attractive but the ISO expansion limit is so high and with good quality that the flash will not required in most of situations (at least in news photography).

The D850’s key strengths are its outstanding colour and dynamic range at base ISO where it edges past its rivals.

Overall, we recommend hybrid photographers and multimedia creators to opt for the best DSLR experience so far in Nikon D850.

Google still allowing third-party apps read your Gmail: Report

Published

on

Washington, Sep 21: After facing a backlash over reports in July that third-party app developers can read your Gmail, Google has once again defended its policy to allow third-party apps to access and share data from Gmail accounts.

According to a CNNMoney report on Thursday, Gmail lets third-party developers integrate services into its email platform.

“Developers may share data with third parties so long as they are transparent with the users about how they are using the data,” said the report, quoting from a Google letter sent to the US Senators.

Google also makes “the privacy policy easily accessible to users to review before deciding whether to grant access”, said Susan Molinari, Vice President of Public Policy and Government Affairs for the Americas at Google, in the letter.

The Wall Street Journal reported in July that despite assuring users to “remain confident that Google will keep privacy and security paramount”, the search giant is still allowing third-party app developers scan through Gmail accounts.

Gmail has nearly 1.4 billion users globally — more users than the next 25 largest email providers combined.

Later, Google said in a blog post that the company is continuously vetting developers and their apps that integrate with Gmail before it opens them for general access.

According to Google, it gives both enterprise admins and individual consumers transparency and control over how their data is used.

“We make it possible for applications from other developers to integrate with Gmail — like email clients, trip planners and customer relationship management (CRM) systems — so that you have options around how you access and use your email,” said Suzanne Frey, Director, Security, Trust and Privacy, Google Cloud.

Before a published, non-Google app can access your Gmail messages, it goes through a multi-step review process at the company, it said.

“It includes automated and manual review of the developer, assessment of the app’s privacy policy and homepage to ensure it is a legitimate app, and in-app testing to ensure the app works as it says it does,” Frey noted.

In 2017, Google had said its computers will soon stop reading the emails of its Gmail users to personalise their ads.

Guests staying in hotels will be able to communicate with the robot via voice command, touch and hand gestures. The robot will in turn respond to them through AliGenie, the software behind Alibaba’s smart speaker, Tmall Genie.

“The robot will be the ultimate assistant for hotel guests who want everything quickly at their fingertips,” added Lijuan.

With a multi-sensor data functionality, parallel computing for quick responses, autonomous navigation system to identify obstacles, communication systems to control elevators and identity verification through facial recognition technology, the one-metre tall robot can walk at a metre per second speed.

“After trial at a hotel, Alibaba AI Labs will assess its suitability for other areas, including hospitals, restaurants and office services,” the company added.

According to the International Federation of Robotics, the global market for service robots is expected to grow from 20 to 25 per cent from 2018 to 2020.
