This morning I installed the latest firmware updates for my D7100. The firmware is C: Ver.1.04 / released 2018/02/27. I also installed the Distortion Control Data Ver.2.017 / released 2018/03/01. It was a successful update. All of my Nikon lenses work properly. However, when testing the Sigma I discovered that autofocus was no longer working. When turned on with the Sigma attached, the control panel on top of the camera starts blinking, and the lens doesn't focus. It doesn't do anything. I can manually focus, but autofocus doesn't work. I checked all settings for the lens and camera. As I mentioned my 3 Nikon lenses work fine. Only the Sigma is affected by the update. I will call Sigma Monday. I would appreciate any advice - BTW I really like the lens and its OS. Thanks, Jim

I have that same lens and love it, it is just as sharp as any of my nikkors. I have heard that Nikon does this sort of thing to stop us from buying third party lenses and batteries. For this reason I will not update my Nikons unless there is something in the update that I specifically want or need!

I also use the Sigma 17-50 f2.8 on my 7100. I will not update the firmware.

Just spoke to Sigma in NY - they will update the firmware for no charge. I need to mail it to their Long Island office (too far to drive). They said they do same day firmware updates so probably 5 business days without the lens. I will let you know the outcome when I get it back.

all my lenses except one are third party so I will not be updating my D7200.

Sigma has a "docking station"; don't know if it works with that lens; ask sigma about it. If so, then you can do the update yourself...

Thanks for the suggestion - however, this lens is not user updateable - so off to Sigma it goes!

I believe that only their art lenses are user updateable through their usb dock.

I think I understand that a firmware update to a camera is really a software update to internal programs. However, I don't know what a firmware update to a lens is unless it is a physical modification which obviously can't be done "online." I recognize this may label me as a real amateur, but would someone politely explain it to me? Thank you.

Here is a cut and paste from the Sigma website about a lens firmware update available that will correct an overexposure issue when using a teleconverter on their 150-600mm lens.

We would like to announce the availability of a new firmware update for the SIGMA 150-600mm F5-6.3 DG OS HSM | Sports in Nikon mount and the SIGMA 150-600mm F5-6.3 DG OS HSM | Contemporary in Nikon mount. This firmware update can be installed using SIGMA Optimization Pro.

The lens firmware update corrects the phenomenon of overexposure when the lens is attached to the SIGMA TELE CONVERTER TC-1401 on Nikon Digital SLR camera “D500”, released by NIKON CORPORATION.

For customers who own the following applicable products and also SIGMA USB DOCK, please update the lens firmware using SIGMA Optimization Pro.

For customers who do not own SIGMA USB DOCK, the lens firmware update will be provided free of charge. Please contact your nearest authorized subsidiary/distributor of SIGMA.

But if you take the drive you can continue to Montauk and shoot some seals.

Nice photos - I love the seashore. The Sigma Ronkonkoma office is too far for me to drive (~150 miles round trip) especially with another Nor'Easter predicted for tonight. It's also cheaper for me to mail rather than pay the bridge tolls to Long Island and back!
