New Sigma 400mm F/2.8 OS Patent Emerges, Next Sport Lens?

By Anthony Thurston on April 13th 2015

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!

    I’ve been blown away by the quality of Sigma’s latest Art series lenses. I rented the old Sigma 300mm f/2.8 years ago when I was shooting with Canon and it was a phenomenal lens. That said, I remember the 300mm f/2.8 being ungodly heavy in the front (my monopod ball head kept losing tension because of the weight up front) … so I’m curious to see how massive a Sigma 400mm f/2.8 will be.

    Still, after how amazing the Art lenses have been, I would love to see Sigma’s take on more affordable versions of the most expensive fast telephoto primes (400mm f/2.8, 200mm f/2, and maybe even a 600mm f/4).

    I would differently love to own a 400 mm f2.8. But the prices canon are charging it will not be possible for me…. Therefor really hoping Sigma is about to release their 400 mm :-)

    This should be an amazing wildlife lens! I can’t wait to see how it compared to the Nikon 400mm.

    Well if the 120-300 f2.8 goes for $4500.00 i can see the 400 going for well over that. But i think it will still be a lot cheaper then the other ones and of the same quality maybe even better…..

    Despite SIGMA being cheaper than the Caonon or Nikon offerings I still feel that an f/2.8 400 mm would be out of my current price-range .

      Well, even at 1/2 price it would cost about as much as a decent used car. It’d be out of my current price range too at this time the way business is going. Making less and less money from the agencies as image prices erode. 3 years ago I’d have bought a $6-7K 400mm f/2.8 OS in a heartbeat.

      This year I’d be thinking more along the lines of the 120-300 f/2.8 OS in crop mode!

    Referring to Sigma’s OS as Image Stabilization is like referring to Nikon’s VR as Image Stabilization.

    Bad. Bad Sigma. Stop it.

    Give us the 24-50 f/2 zoom like the 18-35 f/1.8 crop version. That’s what we need. Or an 85 or 135 Art prime.

      Their current 85mm 1.4 is incredible. No need for an “Art” version for awhile.

      There’s so much money to be made in fast super-teles. They know that high-end pros pony up the cash for them, but most photographers can’t afford to buy a $12K Nikon 400mm f/2.8 VR. So they rent them.

      Put one out there at 1/2 price and they will fly off the shelves with a larger profit margin.

      And I really don’t think the mythical 24-50 f/2 will ever come to fruition. There’s never been a rumor only speculation based on wants. Think of the size of a full-frame limited zoom range lens. It would need a tripod foot.

      Yes to both of those, but would really like a 35-85mm f/2 OS Art lens or a fixed 135mm f/2

      J Dennis — I just see the 400 2.8 as a Ferrari lens price with Ferrari lens performance expectations. Sigma’s IQ will be stellar, but that AF — even a half notch behind Canon — will be a huge deterrent to those kind of shooters. Even if it swoops in at half the price, say $5K, people will expect no AF misses. As such, I see Sigma going after high end superteles as a big leap a little too soon in their development.

      The 400 2.8 is a lens you’d think they’d tackle *after* Art-ing many other lenses with lower AF expectations first: 85 prime, 135 prime, macro, perhaps a 400 f/4 or f/5.6, etc.

      That said, any pressure they can apply to CaNikon to keep prices reasonable is awesome.

      I shot MotoGP and X-Games last year using the 120-300 f/2.8 OS |S and it never missed focus once, my 24-105 always nails it. The 18-35 seems to know where to focus before I do. I don’t see why they would screw up a 400 f/2.8. The only lens I ever have issue with is the 35 and I blame that on myself more than a bad lens. Sometimes I rush focusing with it and I miss, and close focus is easier to blow than a subject that’s far away due to the difference in near/far perspective. There’s not much lens element movement when you’re focused out near infinity.

      In any case, patents are filed every day that never come through as is pointed out in the article. Sigma is overwhelmed filling orders for the 24-105 and the 150-600, I wouldn’t hold my breath for a 400 real soon.
