Sigma launched its new state-of-the-art magnesium alloy processing facility, which is now part of the Aizu plant located in Fukushima, Japan. The new building has three floors and covers about 1995 square meters.
Light weight is an important characteristic for interchangeable lenses, often providing an advantage over other manufacturers’ models, especially large telephoto lenses that use metal exterior parts with high strength and rigidity to securely hold large-diameter lenses as well as protect internal optical elements and mechanisms.
Using metals such as aluminum for this purpose would normally present several challenges, such as the product being too heavy and the aluminum itself being difficult to machine. With this in mind, SIGMA has decided to produce the following magnesium elements for its lenses in-house. In-house production will also allow for more control over the manufacturing process, which will have a significant impact on the quality of the finished product.
Magnesium parts made in the new shop will be used for many products in the future, including the 60-600mm F4 lens.5-6.3 DG OS HSM | Sport, due in October.
This is interesting news! I’m curious to know more about Sigma’s decision to open a machining shop specifically for magnesium alloys. What motivated them to invest in this particular material? How will this new shop benefit their customer base? Are there any unique aspects or advantages of working with magnesium alloys compared to other metals?
