The DSL not R

A camera shoots for the virtues of a DSLR without the motion picture vices

By The Sony Tech Guy | June 06, 2011

The NEX-FS100U is designed from the ground up for motion pictures.

From the moment they came out, HD-capable DSLRs have intrigued shooters with their ability to deliver Hollywood-style selective focus on a micro-budget. But even as HDSLRs have gained adherents, shooters have pointed to a list of pictorial, practical and ergonomic shortcomings. To be fair, these issues are the result of taking an excellent platform carefully optimized for still photography and adapting it for moving pictures. Sony understands. We know DSLRs, we love DSLRs, and we make a growing family of Alpha HDSLRs along with a large-sensor Handycam camcorder with still camera roots: the NEX-VG10, which uses an APS-C size image sensor. But we also wanted to create a purpose-designed professional camcorder that would combine the key benefits of HDSLRs without the limitations. The result is the NEX-FS100U. Read More

Critical Evaluation goes OLED

Sony's first BVM-class Trimaster OLED monitors

By The Sony Tech Guy | June 01, 2011

The truth, the whole truth and nothing but the truth. Sony's BVM-E170 and E250.

The place: Palm Springs. The time: February. The audience: a generous portion of the world's best informed, most demanding users of professional monitors all gathered for the HPA Tech Retreat 2011. It was here that Sony chose to introduce our second-generation OLED monitors: the critical evaluation BVM-E170 and E250. According to Debra Kaufman, blogging for Studio Daily, the retreat's emcee Mark Schubin called these monitors "what we've been waiting for." You can read Mark's own blog posts here and here. Pro Video Coalition's Adam Wilt recaps the technical presentation here. So why are these monitors such a big deal? What relationship do they have to today's high dynamic range cameras? And what does OLED imply for you? Read More

Investing in image sensors

Resting on laurels is not in the playbook

By The Sony Tech Guy | May 20, 2011

The new F65 digital motion picture camera would not have been possible without major Sony advances in CMOS image sensor technology.

Ordinarily, it's hard to see the connection between stuff that directors of photography might be expected to care about (exposure latitude, highlight handling, low-light sensitivity) and $1.7 billion in investments. But when the money goes to Sony CMOS image sensors, the investments become a little more relevant. Recent Sony sensors have been headline news. It started with the launch of the award-winning PMW-F3 camcorder, which also marked the debut of a new Sony Super 35mm Exmor CMOS image sensor. Then came the long-hinted-at 8K sensor of the award-winning F65 camera, another Super 35mm Exmor CMOS design. And then Sony announced, that oh by the way, the NEX-FS100U, another award winner, features the same image sensor as F3. Sony is now actively building on these successes. Read More


AVCHD with a twist

AVCHD with a twist

NXCAM camcorders feature Sony's operations-adaptive codec.

By The Sony Tech Guy | May 04, 2011

Smarter than your average codec: the AVCHD encoder in Sony's NEX-FS100U.

Compression encoders are "content-adaptive." They keep a watchful eye on the complexity of the video signal and make content-based adjustments on the fly. Now a new generation of encoders adds a clever twist. On Sony NXCAM camcorders such as the NEX-FS100U and HXR-NX5U, our proprietary AVCHD encoder is not only content-adaptive, but also operations-adaptive. When you engage camera gain, the control bus signals the encoder, which adjusts accordingly. For example, when you boost the gain, the codec anticipates noise in the scene, minimizes the loss of encoding bits to noise and improves picture quality. When you cut the gain, the codec maximizes picture detail. As a result, you get a substantial advantage: image quality optimized for each gain setting. Read More

Abel Cine has been doing a short series of tests on the new PMW-F3 camera from Sony, and the latest episode is a very thorough dynamic range test. In it, they chart the F3 at a solid 12-stops of dynamic range, and then go on to show how the various Cine Gamma modes affect the way information the camera is capturing. It's a very well done test video, watch below... Read More

LOG rolling with the Sony F3

Sony's S-LOG Gamma encoding reaches a broader audience

By The Sony Tech Guy | February 23, 2011

The S-LOG Gamma curve of the Sony PMW-F3 (blue) maintains camera highlights up to 800% of nominal peak white. This is far beyond the capability of conventional Rec.709 gamma encoding (red).

As the much-talked-about PMW-F3 handheld Super 35mm camcorder hits the streets this month, it comes with the promise of S-LOG Gamma, which will be available as an extra-cost upgrade later this year. S-LOG will join the F3's built-in HyperGamma curves as creative tools for managing high scene contrast. So what can S-LOG Gamma do for your images? How does it differ from HyperGamma? And what are the basic requirements for handling S-LOG Gamma in post? I'm glad you asked. Read More

Next month marks the debut of Sony's first handheld Super 35mm model for professionals: the PMW-F3. It's also Sony's first such camera with XDCAM EX recording and first with CMOS technology. And the F3 starts at just $16,000 MSRP. The new camera is beginning to make a name for itself after some sweet pre-production tests and first-on-the-block Vimeo posts. In this article, we'll take a look at the new camera's Super 35mm image sensor, and see exactly what Sony means by "Super 35." Read More

Resolution and screen size

Is HD "bigger" than SD?

By The Sony Tech Guy | December 22, 2010

The screen corners are rounded, the viewing distances are inexact and the angles aren't accurate. Still, this early SD versus HD diagram was prophetic.

I'm holding a Sony white paper on the proposed 1125/60 international HDTV standard for studio origination and program exchange. You say that standard doesn't sound familiar? It was the forerunner of 1080/60i. The white paper is dated April 1988 and it extols the virtues of future HDTV in terms of more scanning lines, better colorimetry and wider aspect ratio. But the most striking graphic shows an HDTV screen with a whopping six times the area of a superimposed SDTV screen. Why? What, if anything about HDTV translates to a bigger screen? And how closely do the televisions of today reflect the predictions of 22 years ago? Read More

Wherefore 4:4:4?

When numbers get numbing.

By The Sony Tech Guy | December 17, 2010

This picture is worth at least a few words.

So much of the technical jargon around digital content creation is fraught with traps for the unwary. As we've previously written, an image sensor "pixel" is not the same as a recorded "pixel" and nothing about a 2/3-inch type sensor actually measures 2/3 inch. Another classic source of confusion is the seemingly innocuous ratio-such as 4:4:4-that expresses the digital sampling structure. Read More

An affordable, new choice for studio camera conversion

Camera control unit for XDCAM EX camcorders

By The Sony Tech Guy | December 02, 2010

From corporate video studios to public access television to small market call-letter stations, there's a full-court press for affordable HD studio camera solutions. If you want full 1920 x 1080 resolution, full digital signal transport, full camera remote control and a full range of studio facilities, Sony has a surprisingly affordable new option. A new camera control unit (CCU), the XDCU-50 enables low-cost studio configuration with the PMW-EX3, 320, 350 and 500 XDCAM EX™ camcorders. While all these camcorders offer full HD resolution, there's a choice of imager sizes. The PMW-EX3 and 320 offer 1/2-inch type image sensors, while the PMW-350 and 500 step up to full 2/3-inch type imagers. The new CCU is destined to bring big smiles to a lot of faces with an MSRP of $3,500. Read More

By The Sony Tech Guy | November 09, 2010

If it hadn't already been taken, E pluribus unum would have been a great motto for Sony's latest development, XDCAM® Browser version 1.00. This free, downloadable software unifies and simplifies what had been five separate applications for XDCAM and XDCAM EX products. This unification is particularly important now that the recently introduced PMW-500 camcorder and PDW-HR1/MK1 field recorder support both XDCAM and XDCAM EX file types. The new software also operates under both Windows® and Mac® OS. Read More
