Sigma 17-70 2.8 Issue with T6S - No Liveview or Video on LCD

stilgar99 — Sun, 24 Jul 2016 03:12:00 GMT

Folks,

I need some help. I just got a T6S and my Sigma 17-70 2.4 works fine except when I want liveview of try to use video mode. Neither will display anything on the LCD. The lens works fine on my T5i body, including liveview and video. My other lenses seems to work fine on both my T6s and T5i for Liveview...

Any ideas or help?

When you say display nothing do you mean black display?

I ran a test on my T4i. With no lens attached LiveView works. If I select video I get a warning that no lens is attached, but if I select record the display works.

The Sigma 17-70mm F2.8-4 DC Macro OS HSM is a very good lens. I highly recommend it. It is in the general same class as the very nice Canon EF-S 17-55mm f/2.8 IS USM Lens. Slightly more range but really pretty comparable.

It should work! The only thing I can come up with is, possibly, Sigma has not tweaked the firmware for operation with the T6s. Since the camera and other lenses work as they should. That would explain why just the Siggy doesn't work well on the T6s.

The Sigma 17-70mm F2.8-4 DC Macro OS HSM is compatible with Sigma's USB dock. It allows you to connect the lens to your computer to update the firmware. Plus some other adjustments. The dock is a feature that Sigma has on some lenses. It guarantees the lens will work properly with future Canon cameras. Purchase the Sigma USB dock.

The Sigma 17-70mm F2.8-4 DC Macro OS HSM is a vast improvement over the standard 'kit' lens. When it works, that is!

Thanks for the response. I guess Im just trying to determine if I have a issue with my new t6s and need to return it.
I agree that based on the data and inputs from others, it sounds like a lens issue. However it would sure be nice to hear if any other T6s owners have seen this with the Sigma 17-70...

Go online and see if any reviews mention using a T6s. Check some of the largest online Canon retailers, who will likely have the most reviews. I say buy the Sigma Dock, because it can also perform firmware updates on lenses. The Sigma Dock is a good tool to have on hand, anyway.

"Go online and see if any reviews mention using a T6s."

I generally don't like that suggestion and I don't really recommend it. You never know if the other owners know what they are doing or not. But I suppose if you did see a preponderance or trend it might be OK.

The Sigma USB dock is the way to go. If the lens still doesn't work after a firmware upgrade, there could be something wrong with the T6s. I really doubt that but, hey, anything is possible.

Get the dock. If the lens still doesn't work I would call Sigma first before suspecting the T6s.

The Sigma web site has a "DC Lens Compatibility Chart" for their current lenses. It can be found under the RESOURCES link on the lens data page.

http://www.sigmaphoto.com/lenses/lens-resources/dc-lens-compatability-chart

I see the T5i listed for use with the lens, but not the T6s, T6i, 80D, T6, or even the 7D2 or T5..

If other lenses work and this *THIRD PARTY LENS* does not, it is probably a lens issue. See if sigma has a firmware update for the lens.

Good catch. I see two paths to a solution. Sending the lens to Sigma, at an unknown cost. Don't forget about shipping costs and insurance, either.

Or, purchase a Sigma Dock and do the firmware update yourself. BTW, the Sigma Dock will do the firmware update pretty much automatically for you. You just need to click OK, after the software finishes checking your lens.

"Sending the lens to Sigma, at an unknown cost."

Maybe, than maybe not! Sigma's CS is not Canon's customer service! Not by a long shot. They are getting better. It is generally an unknown. Period. They may do the firmware update for free and sometimes they won't. It might take three days and it might take three months. A call first or email is better. And the Sigma dock is best.

One thing that really galls me is when guys rank on Canon's CS and have no idea just how good it is compared to any other camera/lens maker. Even Nikon! None are in the same class as Canon when customer service is concerned. Sorry, had to get that rant out. I'm OK now, more coffee, please.

Repeat,

" And the Sigma dock is best." This would have settled it a long time ago!

The notice that John unearthed does say that they'll provide the update for free. But that may apply only if you have the dock.

And the underlying point is valid: When you buy a lens from a 3rd-party vendor that has no arrangement with Canon to obtain the relevant specs, you'll have problems if they get it wrong. (You probably won't find that caveat in their advertising, BTW.)

That said, I suppose the user community benefits from Canon having the competition.

I admit Sigma and Tamron have gotten better recently with CS. I suppose they had to since both offer multi-year warranties now. When they did so I thought, "good luck with that". Sigma changed hands and the new guy has made a big difference. He started the Art series. I have talked with the Tamron rep and he told me Tamron was trying to improve its CS, too.

We'll see as time will tell. I would still buy the dock!

Even if Sigma does fix it for free, does that include shipping the lens [to and from] and insurance both ways? If so, that would be awfully generous of them, even if it is a bug in their firmware.

Buying a Sigma Dock is probably the least costly, lowest risk thing to do. It costs less than the shipping from most U.S. locations, and most reputable vendors will ship it to you for free by the 2nd or 3rd day.

They didn't used to. I doubt they have changed that.

Many Thanks,

Dan

Nope, it is a lens firmware issue.

The other option is to get rid of the lens.
