Sigma Intros Magnetic Lens Caps

This is probably the least meaningful lens development in the past week, but it will assuredly be the most noted across the ages. People love magnetic mechanisms. Sigma’s new cheap-and-cheerful line of Sony E-mount lenses is to sport magnetic caps (in Japanese).

Sigma’s previous lens caps for their high-end Art series have been the only thing about those lenses that appeared to me made cheaply. The early Art lenses employed a cheap plastic, and used friction locking mechanisms that wore poorly. More recent Art releases featured rubberized materials and locking detents.

Taking lens caps to a new level, it can’t be far off that a third party makes a metallic shirt pocket insert, allowing a fast-moving photographer to swipe the cap off and swipe it onto the shirt pocket without looking.
