Introducing the HD PENTAX DA645 28-45mm F4.5 ED AW SR Lens

The HD PENTAX-DA645 28-45mm f/4.5 ED AW SR Lens Provides Users of the 645D or 645Z With a Weather-Resistant, Ultra-Wide-Angle Zoom Lens, With a 35mm Equivalent Focal Length of 22-35.5mm.

NEW YORK, NY--(Marketwired - August 04, 2014) - The HD PENTAX-DA645 28-45mm F4.5 ED AW SR is the first ultra-wide-angle zoom lens in the 645-system lens lineup that can be used on both 645Z and 645D cameras. This is ideal for landscape photography, where delicate angle-of-view adjustments can be difficult due to the restricted footing, and for architectural photography requiring a wide angle of view despite the close distance to the subject. Read all about the Pentax HD PENTAX-DA645 28-45mm f/4.5 ED AW SR lens here: http://www.bhphotovideo.com/c/product/1072808-REG/pentax_hd_pentax_da645_28_45mm_f_4_5.html

High-performance Super-wide Zoom

Covers super-wide angle of 22-35.5mm equivalent to 35mm format

Internal Shake-reduction Mechanism

PENTAX provides shake reduction feature for medium-format cameras. Compensates for camera shake up to approximately 3.5 shutter steps

Dustproof, Weather-resistant Construction

By mounting the HD Pentax-DA645D lens onto a PENTAX 645D and 645Z, the user is assured of greater durability and reliability when shooting in the rain or mist, as well as at locations subject to spray or splashes. 

HD Coating and Aero Bright Coating

Delivering sharp, clear images, free of flare and ghosting, even under demanding lighting conditions such as backlight.

High Effectiveness of Lens Hood

The newly developed lens hood is designed based on the size of 645Z and 645D image circle. This maximizes the effectiveness of the lens hood even with wide angle lens. The Pentax HD PENTAX-DA645 28-45mm F4.5 ED AW SR lens's front frame extends to its maximum length at the 28mm setting, and retracts to its shortest length at the 45mm setting. This makes Lens hood work quite effectively over the entire zoom range.

High Compatibility with Multiple Filters

You can attach the filter at the lens front. This allows the user to select from the many kinds of filters available in the market. The size is 82mm. Since the first lens element of ultra-wide-angle lenses is usually highly convex, most ultra-wide-angle lenses can't accept a filter.

In-lens DC Motor

Smooth, quiet AF operation using a lens-installed AF driving motor. DC motor provided sufficient drive torque and driving speed with minimal noise 

Circular Aperture Blades

Round-shaped diaphragm produces a natural, beautiful bokeh (blur) effect, while minimizing the streaking effect of point light sources.

Quick Focus System

The lens features the Quick-Shift Focus System, which allows the user to instantly switch to manual-focus operation after the subject is captured in focus by the camera's AF system.

SP Coating

SP (Super Protect) coating to keep the front surface free of dust and stains.

As enterprises work to take advantage of Big Data technologies, they frequently become distracted by product-level decisions. In most new Big Data builds this approach is completely counter-productive: it presupposes tools that may not be a fit for development teams, forces IT to take on the burden of evaluating and maintaining unfamiliar technology, and represents a major up-front expense. In his session at @BigDataExpo at @ThingsExpo, Andrew Warfield, CTO and Co-Founder of Coho Data, will dis...

Most people haven’t heard the word, “gamification,” even though they probably, and perhaps unwittingly, participate in it every day. Gamification is “the process of adding games or game-like elements to something (as a task) so as to encourage participation.” Further, gamification is about bringing game mechanics – rules, constructs, processes, and methods – into the real world in an effort to engage people. In his session at @ThingsExpo, Robert Endo, owner and engagement manager of Intrepid D...
Eighty percent of a data scientist’s time is spent gathering and cleaning up data, and 80% of all data is unstructured and almost never analyzed. Cognitive computing, in combination with Big Data, is changing the equation by creating data reservoirs and using natural language processing to enable analysis of unstructured data sources. This is impacting every aspect of the analytics profession from how data is mined (and by whom) to how it is delivered. This is not some futuristic vision: it's ha...
WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.

In his session at @ThingsExpo, Chris Harrold, Global CTO for Big Data Solutions for EMC Corporation, showed how to perform a simple, but meaningful analysis of social sentiment data using freely available tools that take only minutes to download and install. Participants received the download information, scripts, and complete end-t...
For manufacturers, the Internet of Things (IoT) represents a jumping-off point for innovation, jobs, and revenue creation. But to adequately seize the opportunity, manufacturers must design devices that are interconnected, can continually sense their environment and process huge amounts of data. As a first step, manufacturers must embrace a new product development ecosystem in order to support these products.
Manufacturing connected IoT versions of traditional products requires more than multiple deep technology skills. It also requires a shift in mindset, to realize that connected, sensor-enabled “things” act more like services than what we usually think of as products. In his session at @ThingsExpo, David Friedman, CEO and co-founder of Ayla Networks, discussed how when sensors start generating detailed real-world data about products and how they’re being used, smart manufacturers can use the dat...
When it comes to IoT in the enterprise, namely the commercial building and hospitality markets, a benefit not getting the attention it deserves is energy efficiency, and IoT’s direct impact on a cleaner, greener environment when installed in smart buildings. Until now clean technology was offered piecemeal and led with point solutions that require significant systems integration to orchestrate and deploy. There didn't exist a 'top down' approach that can manage and monitor the way a Smart Buildi...
