The Golden Ratio is a mathematical construct that has been observed all throughout nature, architecture, and art. And some think it’s a universal constant, and divine. But… is it? Or are we only seeing what we want to see?

There’s a right way and a wrong way to clean a camera lens. We show you the best – and worst – ways to do it!

The french website Phototrend had a chat with the Nikon marketing department. A couple of highlights:

• we plan to move faster on the schedule presented with the introduction of the Z mount system in terms of expanding the range of lenses.
• we have a lot of demand for pancake type lenses
• the development priority will be the extension of both our range of (Z-mount) cameras and lenses,
• we will meet the needs of hybrid photographers who take not only still images, but also video,
• we recognize that DX format (APS-C) hybrid cameras are an important category for providing a portal for amateur photographers.

Now we are ready for 500 megapixel cameras and 8K video :)

The SD Association announced today the SD 8.0 Specification for SD Express memory cards receives even faster transfer speeds by using the popular PCI Express^® (PCIe^®) 4.0 specification delivering a maximum of nearly 4 gigabytes per second (GB/s) data transfer rate. These full sized cards continue to use the NVMe Express™ (NVMe™) upper layer protocol enabling advanced memory access mechanism. As always SD Express memory cards using SD 8.0 specification maintain backward compatibility.

“SD Express’ use of even faster PCIe and NVMe architectures to deliver faster transfer speeds creates more opportunities for devices to use SD memory cards,” said Mats Larsson, Senior Market Analyst at Futuresource. “This combination of trusted and well-known technologies makes it easier for future product designs to leverage the benefits of removable storage in new ways.”

SD Express gigabyte speeds bring new storage opportunities for devices with demanding performance levels, across a variety of industries. The cards can move large amounts of data generated by data-intense wireless or wired communication, super-slow motion video, RAW continuous burst mode and 8K video capture and playback, 360 degree cameras/videos, speed hungry applications running on cards and mobile computing devices, ever evolving gaming systems, multi-channel IoT devices and automotive to name a few. SD Express will be offered on SDHC, SDXC and SDUC memory cards.

“By dramatically increasing the speeds for SD Express we’re giving device manufacturers and system developers more storage choices,” said Hiroyuki Sakamoto, SDA president. “SD 8.0 may open even more opportunities for extra high performance solutions using removable memory cards.”

“PCI-SIG^® is pleased to see that SDA is continuing to adopt even faster PCIe technology configurations using PCIe 4.0 interface and dual lanes for one of the top leading removable memory cards – SD,” said Al Yanes, PCI-SIG president and chairman. “PCIe specification conformance tests are available today by major test vendors, offering a significant advantage for any new PCIe technology adopter.”

“NVMe is the industry-recognized performance SSD interface from the client to the datacenter, shipping in millions of units,” said Amber Huffman, NVM Express™ Inc. president. “Consumers will benefit by SD Association continuing the adoption of the NVMe base specification for their latest SD Express cards.”

SD Express uses the well-known PCIe 4.0 specification and the latest NVMe specification (up to version 1.4) defined by PCI-SIG and NVM Express, respectively. SD 8.0 specification provides two transfer speed options for SD Express memory cards. The two transfer speeds are accomplished by supporting either PCIe 3.0 x2 or PCIe 4.0 x1 architectures with up to ~2GB/s and with PCIe 4.0 x2 technology with up to 4GB/s. SD Express cards offering PCIe 4.0 x1 architecture use the same form factor as defined for SD 7.0 specification cards with a second row of pins to deliver transfer speeds up to 2 GB/s. SD Express cards supporting dual PCIe lanes (PCIe 3.0 x2 or PCIe 4.0 x2 technologies) have three rows of pins.

The SDA makes adoption of SD Express easy allowing companies to use existing test equipment and saving in product development costs. The SD 8.0 specification continues giving system developers access to PCIe and NVMe technologies, such as Bus Mastering, Multi Queue (without locking mechanism) and Host Memory Buffer.

Two revised white papers, “SD Express Cards with PCIe and NVMe Interfaces,” and “SD Express and microSD Express Memory Cards: The Best Choice for Your Future Product Designs” provide an in-depth look at the opportunities created by SD Express. More information is available on our website.

Samsung Introduces 1.2μm 50Mp ISOCELL GN1 with Faster Auto-focusing and Brighter Images

Dual Pixel technology creates 100-million phase-detecting photodiodes for snappy auto-focusing and light information that can be translated up to 100 megapixels
Tetracell technology enables light-sensitive 2.4μm pixels for ultimate low-light photography

Samsung Electronics, a world leader in advanced semiconductor technology, today introduced Samsung ISOCELL GN1, a new 50-megapixel (Mp) image sensor with large 1.2μm-sized pixels. The ISOCELL GN1 is Samsung’s first image sensor to offer both Dual Pixel and Tetracell technologies. Thanks to the relatively larger pixel size, the GN1 brings image sensor performance to a new level with a combination of elevated light sensitivity for stellar low-light photos and DSLR-level auto-focus speeds, optimized for more dynamic picture-taking experiences.

“With innovative pixel technologies, Samsung has been at the forefront of offering high-performance image sensors that closely cater to increasingly diversifying market needs. The ISOCELL GN1 is part of that commitment to deliver stunning images to consumers in any environment,” said Yongin Park, executive vice president of sensor business at Samsung Electronics. “We will continue to introduce image sensor solutions at the cutting-edge that will lead the next trends in mobile photography.”

Creating desirable images is an indispensable element for today’s smartphone users who are well accustomed to visually grasping and cherishing special moments, wherever they are. To address various imaging preferences of the users, some smartphone makers put more emphasis on extremely detailed images with ultra-high resolutions, while some choose bigger pixels for bright results in low-light environments. The new Samsung ISOCELL GN1 fulfills these multiple needs at once with Dual Pixel and Tetracell technologies.

The GN1 brings best-in-class auto-focusing with 100 million phase detection auto-focus (PDAF) agents. Samsung’s Dual Pixel technology places two photodiodes side-by-side within a single pixel that can receive light from different angles for phase detection. With all of the sensor’s active pixels working as auto-focusing agents, the GN1 can detect and focus onto a desired still or moving object from every corner in an instant, even in low-light conditions. When capturing images, a single pixel output is created by merging the outputs from the two photodiodes within the pixel. Samsung also provides a software algorithm that takes light information from each photodiode to produce image resolutions comparable to 100Mp.

For ultimate low-light photography, the GN1 adopts Tetracell technology, a pixel-merging technique that improves the pixels’ capacity to capture and process more light. By binning four pixel signals into one, Tetracell doubles the image sensor’s pixel size to 2.4μm and quadruples the light sensitivity to take brighter 12.5Mp photographs. With improved light sensitivity combined with a powerful auto-focusing solution, the GN1 is able to focus on an object quickly even in extreme low-light environment to deliver both brighter and sharper results.

In addition to Dual Pixel and Tetracell technologies, the GN1 comes with Smart-ISO that intelligently selects the optimal ISO, real-time HDR that captures the scene in multiple exposures simultaneously, and gyro-based electronic image stabilization (EIS) that takes sharp images and video even when in motion. For premium video quality, the image sensor supports video recording at up to 8K resolution at 30 frames-per-second (fps).

Samsung ISOCELL GN1 started mass production this month.
