There are currently only two lenses in Sigma’s high performance ‘Sports’ lineup: the incredible 120-300mm and the new 150-600mm. If a new patent is any indication, it seems that Sigma may have another Sports lens coming down the pipe in the form of a new 400mm F/2.8 OS.


The patent, discovered by Egami, was only recently published but was filed way back in September of 2013. The design features 15 lens elements in 5 groups, and as mentioned in the name, does include Sigma’s OS (Image Stabilization) technology.

Being a sports and wildlife guy on the free time, this lens in particular really excites me. 400mm F/2.8 lenses from Canon and Nikon costs insane amounts of money, a Sigma offering would no doubt be much more reasonably priced, and if recent releases are any indication – still a great performer.


As always though, patents do not mean a lens is going to make it to market. All it shows us is what Companies have been working on, and, in this case, the patent was filed almost two years ago. So this lens could easily be dead in the water at Sigma, or maybe it is one of their next releases – who knows.

All I know is that it is still incredibly difficult to get your hands on their new 150-600mm lenses, so I doubt we will see another super-telephoto offering until the supply for those two lenses are satiated.

Would you like to see a new Sigma 400mm F/2.8 OS lens? What do you imagine such a lens would cost in today’s market? Leave a comment below and let us know what you think!
