Sigma 150 500
Sigma 120-400 or Sigma 150-500?
I'm going on safari next year. I have a Nikon D60 and I wondered which camera gives the best result and quality, because that's all I'm looking for.
My! What a coincidence! Just a few days ago, I asked this in many places around the Internet, that is, of course, this site also. not wanting to offend anyone, I have hardly any response and were immensely useful. But what I have done, now, an extensive research and have concluded that I will get the 150-500mm. The image quality differs only in the opening, and only if the initiation of a stop more than 400 mm-120 (or, lower f / number) is used, obviously. So unless you need to stop about an opening, which is unlikely, then get the 150-500mm as me. Here in Australia, the price difference is about $ 300, but I am willing to pay. The two are heavy. The 150-500mm is especially large. The operating system (stabilizer optical) shaking a lot, so you always get this big vibration. However, you will get used to it. Not exactly very, very strong at 100% crop of 400-500mm, but it is a very, very small difference compared to the Canon 100-400mm. Unless you are a complete professional, I doubt they care or even notice. Saturation increases, however, so be sure to review and lower the pitch if necessary. Y. se. large. But good luck on your safari.

How to compete with Asia and the triumph
What is the ultimate goal of customer service? At DC Electronics, a wiring harness Cable and installation company based in San Jose, California, in Silicon Valley, every employee can answer this question. Service Policy as boldly, "the success of any client.
With a comprehensive range of an ordinary life, factors influencing the success of customers evolve. To keep ahead of these changes, DC has expanded its service focus to include not only without error, the timeliness of and delivery, but also a new approach to the art of product management. By taking more responsibility for this function, DC can reduce costs customers beyond the cost savings overall, which gives your customers and your company a competitive advantage.
"We are managers use base. We do everything, "said the vice president of sales and marketing, Chris Hinshaw. "This is to maximize the effectiveness of services and reduce the total cost.

In some cases, services of CC products database management, including even the placement of employees in the customer premises DC short or long term. For example, two employees working solely because CC Applied Materials in Austin, Texas. At the end of the year, customers cons DC should have five members on the CC site staff.
DC In 2005, he opened a branch in Singapore to support its operations with Asian clients. The DC office there, with three managers and one administrative assistant, addresses prototyping and processing orders for the assembly of 15 employees in production a facility of 12,000 square meters near the rooster, Indonesia.
The markets in providing products and services are diverse DC. DC has 150 customers in sectors such as agriculture, construction, industrial manufacturing, medical, nuclear, semiconductor, telecommunications, transport and underwater.
"We have a wide range of clients to protect us against economic downturns, because our segments them," said Hinshaw. " We are very strategic for our business and diversify our portfolio. We do not commit too much to risk. "No one customer over 18 per cent of companies DC.
The largest sector at 34 percent is medical, and major customers are Varian, Philips Medical and Surgical and intuitive. Contract manufacturing is the second largest segment at 22 percent, and major customers are Flextronics, Solectron, Reference and risk.
In third place at 20 percent is the scientific instrumentation industry and whose clients are Trimble, coherent and Agilent. Market semi-conductors, of which 12 percent is fourth with Applied Materials as the main customer.
Eight percent of companies are from the DC Department Engineering which consists of eight engineers and technicians on the ground 35. In addition to prototypes, which are involved in projects such as repairs on site, built and reworked. For some large customers, DC offers services only – not products. Until 3000 Auto CAD drawings are produced annually.
"One of our great strengths is the engineering and field services, "Hinshaw said, noting that four years ago the Engineering Department began communicating with him. "Department of Engineering OOUR truly differentiates us from other companies in the industry."
After recording U.S. $ 28 million in sales last year, income in 2007 should reach 30 million. For 2008, the number should grow at a robust 20 per cent 36 million dollars. This amounts from 2001 to 2006, when sales have doubled, largely due to growth in medical engineering services and segments. profitability targets are achieved each year.
Growth is also the result of so-called "drop-in activities or not covered by DC. Run orders early intervention, contributing to 30 percent of total sales DC.
"Because many of our customers are season and 70 percent as planned, we can free our factory orders abandoned building, "said Hinshaw." Once we are filled with a fall to 700 of the fan assemblies in three hours. Even hesitate to take control of this kind. One way to handle a commodity is to keep slack in the line. "
Among the cable assemblies and wire harnesses, all custom small market volume, DC, for many types. Include flexible cord semi-rigid coaxial cable sub-miniature, discrete, circular, high-density MDR IDC (1 and 2 mm), PCMCIA and SCSI (I-III). Some assembly is electro. DC has a Class 10,000 clean room and manufacturing of ESD.
The easiest product the DC is over six inches with a terminal at each end. Instead, the most complex harness that has 15 hours to build. Longest cable is 500 feet. Cost ranges from about 40 cents to $ 8.000.
DC has tools in a machine shop fully equipped CNC Haas mini mill with a player and a Sharp electric discharge machining. Injection molding is done in Newbury 30-ton presses. Among the items are Insert molding, handles, cables intelligent, molds and dies and ferrite. The products are manufactured ilicone s, Santoprene and PVC in different colors, including Pantone range.
Among the pieces of equipment are Schleuniger stripping machines. planned acquisitions include a tester of the curve, environmental chambers, salt spray testing unit and a temperature and humidity.
"We do everything ourselves, which is easier than agriculture, "said Ruben Macias Jr., 37, vice president of operations." We can not have time to get online Moreover, because we have to offer our customers. "
The products are manufactured in a building of 32,000 square feet by a team 200 people, including 35 in the second round. Manufacturing cells are used, so that all production workers can make a complete build, including pretesting.
An order may include a point or up to 12,000 units per year. Over one million items are produced each year. Sixty-five percent of them from out of state, 30 percent are in California and five per cent outside the United States.
With an average of 18 pieces per kit, 5,000 kits will be sent monthly. Eight years ago, that figure was less than 1.000. Macias has attributed the marked increase in production, the application Six Sigma, 5S, ISO 9001:2000 and 620-A. Staff training is ongoing.
Macias also noted the low turnover, the Assembly had average DC worked for nine years. "They know their jobs, to accept the change and growth and maintain with our customers. Some things you have to ramp and the hard drive, and our people can actually do. I am proud to work with them. "
The production also is high due to work environment described by President Dave Cianciulli Jr. as "honest and open with everyone. Nothing is hidden," he said. "I do not want someone in a department not succeed because someone in another department. In this way, society suffers, as customers. "
The administrative staff consists of 40 persons led by Cianciulli, Hinshaw and Macias. They are assisted by managers Martinez Leonard, the quality Q, Vince Nguyen, M aterials, David Tran, production, Chris Gill, Human Resources and ACCOUNTANTS A, and Lou Bottini, F. Financing KA MANAGEMENT Chua is the director of facilities in Singapore and CK Chua is the director g eneral for Asia.
Everyone in DC is indebted to David Cianciulli Sr. for start-up in 1979 in a 1200 square foot office and warehouse in Sunnyvale, California, he was representative of the company of a man who sells devices interconnection such as connectors and cables. Its mission was to provide high quality products and customer service.
In 1982, DC became a distributor of 3M products. The transition to production was made in 1987 as customers continued to request meetings. As the company increased, the various facilities is required, and DC has been in two places at two Santa Clara and San Jose, each for three years before moving in the existing building.
Mr. Cianciulli, 65, retired 10 years ago, and his son became president. Prior to this position, Cianciulli, Jr., 42, has worked in telemarketing customer service and sales.
In his role as President, Cianciulli continues to focus on sales and new markets with low volumes and meet the wide variety of niche DC. "We differ from other companies in two important ways," says Cianciulli. "Firstly, we can make a piece if that's what the customer wants. We are created only for prototyping, as well as orders important. A company that 100,000 pieces per year, can not fill orders that require a prototype five-piece construction. DC has a huge amount thereof. Second, no business approach that we are at war. We partnerships and strategic alliances with companies in cable assembly. We look at what makes the most sense in the long term, not only what will make us more money in the short term. "
Cianciulli makes this point adding: "I have no problem with investing in a customer if it is promising as a long term partner. If we wait a year to see some recovery, "says Cianciulli:" I'm fine with that. "<A href =" http://www.dcelectronics.com "> From Custom Cable <Asamblea Electronics / a>

Sigma 50-500mm or Sigma 150-500mm. Who has a better image at the end of 500 mm?
I know the 50-500 is an EX model, but a 150-500 OS is a wash or if the quality of the image being noticed? Thank you!
The Sigma 50-500mm (aka Bigman) hands down is a better model. The I was told 150-500 you have serious quality problems as they go further in the length of the lens. If you can get it, stick to Bigman. It is heavier, but the quality shows almost all ranges.
