Apple is really pushing the new camera in the iPhone 4s and without a doubt it is a great camera for a cell phone, but what does the video footage look like when compared to video shot with a Canon 5D Mark II? Take a look at the video above and see for yourself. In some cases the iPhone 4s look better than the 5D.
***You can download the full 1080p version of this video for a more accurate presentation.
Here's a "fair" test between the iPhone 4S and the Canon 5D MK II. I made a little rig that allowed me to shoot both cameras at the same time side by side. All scenes are perfectly synced together so you can pause and scrutinize the frames! See photo of the makeshift rig in the photo area.
Exposure, shutter speed, frame rate and picture style were matched as close as possible between the two cameras. (I used the Zacuto Z-finder to help me adjust exposure for both iPhone and 5D)
This test shows that the tiny F2.4 lens and sensor on the iPhone are pretty nice. It even got a little depth of field!
I did not overlay the exact ISO and Stops 5D settings per shot. It was too much to keep track for this simple test. To be fair I matched 5D exposure to the iPhone so no "Cinestyle" / 24p here.
Here are the settings:
iPhone 4S
- AE.AF locked. That's all you have!
Canon 5D MKII
- Canon 50mm 1.4
- ISO 160 ~ 640 (varied per shot to match the iPhone)
- F 7~22 (varied per shot to match the iPhone)
- Shutter 1/60th
- Auto WB
- Standard Picture Style
- 1080p 30
Kodak Sells Image Sensor Business to Platinum Equity
ROCHESTER, N.Y., November 07 - Eastman Kodak Company (NYSE:EK) announced today that it has completed the sale of its Image Sensor Solutions (ISS) business to Platinum Equity in a move that will sharpen Kodak’s operational focus and strengthen its financial position.
While the financial details were not disclosed, Kodak will have continuing access to the image sensor technology involved in this transaction for use in its own products. Kodak has previously communicated that it would sell assets that are not central to its transformation to a profitable, sustainable digital company. This sale is aligned with that strategy to generate cash to complete the transformation.
Included in the sale is a 263,000 square foot facility in Eastman Business Park in Rochester, N.Y., that houses manufacturing and research facilities.
The ISS business develops, manufactures, and markets the world’s highest performance solid state image sensor devices. Over the past 30 years, Kodak’s image sensors have delivered unrivaled image quality and innovative features for use in a broad range of demanding imaging applications. From precision manufacturing inspection to digital radiography, from earth imaging satellites to traffic monitoring, from the world’s highest performing studio photography cameras to DNA sequencing systems, customers around the world rely on high-performance products from ISS in the most mission-critical applications.
Platinum Equity is a global M&A&O® firm specializing in the merger, acquisition and operation of companies that provide services and solutions to customers in a broad range of business markets.
“Image Sensor Solutions is a business that is well-positioned in the high-performance imaging markets in which it participates,” said Pradeep Jotwani, President, Consumer Digital Imaging Group, and Senior Vice President, Eastman Kodak Company. “This sale maximizes shareholder value by obtaining a full and fair valuation for this business, and allows Kodak to increase its financial flexibility.”
Jotwani noted that Platinum Equity brings significant financial and operational resources to the ISS business and a comprehensive plan to ensure its continued success.
“Platinum Equity is an ideal acquirer of Kodak’s ISS business because they are committed to the success of the business for the benefit of customers and employees,” Jotwani said. “I’m very pleased that we have such a favorable outcome for all of our constituents.”
Platinum Equity focuses on acquiring businesses that can benefit from the firm’s extensive in-house capability and expertise in transition, integration and operations.
“This is a great opportunity to acquire a business with an impressive record for delivering innovative solutions to customers around the world,” said Brian Wall, the partner at Platinum Equity who led the team pursuing the acquisition. “The ISS business has a strong management team with the right vision for leading the company into the future. We share their commitment to product development and customer service and are committed to helping the business realize its full potential.”
Wall said Platinum Equity’s experience managing complex transitions from corporate parent companies will benefit employees, customers and other partners.
“Our operations group will work hand-in-hand with the management team to ensure a seamless transition while allowing the organization to stay focused on delivering world class imaging products and solutions,” said Wall. “We are proud to have forged a unique divestiture solution in partnership with Kodak that serves the best interests of everyone involved.”

Carl Zeiss presents the Distagon T* 2/25 ZE and ZF.2 moderate wide-angle lenses. The large image angle allows photographers to capture exciting perspectives. With its excellent imaging quality at all aperture settings, the lens flexes its muscles particularly for photo documentaries in interior rooms where space is at a premium, as well as for pictures of objects, architecture and landscapes. In many situations, a flash is an unwelcome feature — at family gatherings, in a museum or in a church for example. To capture the mood in such places, photographers gladly do without aggressive lighting and instead work with particularly high-speed lenses that enable short exposure times even under difficult lighting conditions.
The optical experts have now virtually eliminated the chromatic aberrations on these lenses through a special design and selection of materials. Selected types of glass and two aspheric surfaces prevent color fringes from appearing on high-contrast edges. “The Distagon T* 2/25 elegantly combines a compact design with a large initial aperture,” explains Christian Bannert, Senior Director of Product Development in the Camera Lens Division at Carl Zeiss AG.
Lens elements meticulously crafted to minimize stray light and reflections in the lens, and theCarl Zeiss T* anti-reflective coating to increase light transmission enable high-contrast image rendition and color saturation.
The previously available Distagon T* 2,8/25 ZF.2 will continue to be on stock and supplements the new Distagon T* 2/25.Therefore, this new lens is also the first 25-mm lens of Carl Zeiss for theEF-bayonet.
The Yale School of Engineering & Applied Science presents the 2011 Victor M. Tyler Distinguished Lectureship in Engineering with Eric Fossum, Professor of Engineering in Dartmouth's Thayer School and a consultant to Samsung Electronics' Semiconductor R&D Center. Dr. Fossum, who earned a PhD in electrical engineering from Yale in 1984, is one of the world's leading solid-state image sensor device physicists, best known for inventing the CMOS image sensor. His "camera-on-a-chip" technology is used in nearly all camera phones and webcams, digital-still cameras, high-speed motion capture cameras, automotive cameras, dental x-ray cameras, and swallowable pill cameras.
An entrepreneur as well as inventor, Fossum's transfer of his own IP portfolio to industry has yielded one of Caltech's greatest licensing revenue streams, and he has served as CEO of two successful high-tech companies. His work was included on Reuters' list of "Baby Boomer Inventions that Changed the World," and Forbes calls him an inventor who has "changed your life."
