Like any manufactured product, Nikon’s products are also prone to quality assurance / quality control issues. While Nikon has a very extensive and comprehensive quality control process, some defective products can slip through and make it to the market. Other times, the pressure to increase the production output on Nikon’s manufacturing plants is so high, that the initial shipments of a newly introduced product can be defective or could have other problems not discovered during the initial testing of the product. Unless the defect is of physical nature, the latter is typically addressed through firmware updates later, which Nikon is pretty good about.
In this article, I would like to point out some of the recent quality control issues I have seen in Nikon products. Specifically, on the latest generation DSLRs like Nikon D700/D5100 and some of the newer lenses, like the Nikon 24-70mm f/2.8G. Why am I doing this? Because first, I want to make our readers aware of potential QA (Quality Assurance) issues they might encounter and second, I want to provide some information on how to react to such problems. Please bear in mind that the purpose of this article is not to scare existing or potential Nikon customers. In fact, every manufacturer, including Canon and Sony occasionally have issues with defective parts and products, so this article could apply to other brands as well.
