I noticed this weekend when I decided to take the combo M6+Sigma 17-70 Contemporary to a walking event that there is a problem wit OS function in this combo.

I say combo, because I tested the sigma with other cameras and is working fine, and also tested the same with other adapted lens (canon 55-250 STM) and also no problem. I use an oficial canon M-EF adaptor, and all cameras/lenses are FW updated.

So the problem is when I shutdown the camera with the OS selector ON. The camera will be freeze (not turn on) during aproximatelly a minute. Until emit a chattering noise. If I was using the OS and imediatelly before poweroff the camera swith the OS selector to OFF, the camera power off ok and I ear the chattering noise from the lens. This is the same when working with other cameras, including the original M. If I didnt use the OS at all there is no chattering noise.

The sigma lens manual states something regarding this minute to the OS became active, but just to alert that could take some time to the OS became effective I think. Not related with this problem, but could be related somehow.

NOTICE (Except Sony / Pentax)
This lens is powered from the camera. The stabilizer unit will be placed to a
specific position in the lens body and then shooting will be possible (stabilizer
unit will switch to active status) regardless of the OS Switch position. The
active status will take approximately a minute from turning the camera on or
depressing the shutter button “half-way”.

My question is if anyone also can check if this happen with this combo or equivalent (similar lens or body)

Then one would need to contact Canon & Signa and explain the issue. if the camera was purchased second or third hand, I would suggest performing a hard reset of the system. make sure the leads are clean and clear of any obstructions. If you're using a speed booster or extension tube, you may need to consider another manufacture for this option.
 
I have just bought a Sigma 100-400 C lens. I have had it just a few days so I haven't used it yet apart from a few test shots. The instructions are a bit contradictory about this. In one section is says never to turn the camera off whilst OS is switched on. In a later section it says that turning the camera off with OS switched on will cause a chattering noise, but it states this is normal and no cause for alarm.

I am going to take the latter version as being more sensible. I really don't want to be turning OS off and on again every time I turn the camera off. No other lens I've ever owned has required this. I would think most users would find this incredibly tedious and would not bother either. I would expect the lens to be designed to cope. I'd be interested to hear other opinions on this though.
 
I guess this is one reason I avoid third party lenses. But I do have a third party adapter which seems to be doing very well for the last few years.

Today I sent an email to the Sigma contact of my country. Let's see what happens.

I didn't sent to canon because I don't think they will bother because a third-party lens malfunction...but could be wrong...

I'm using the canon adaptor.

I could make a hardreset and see, but got the camera already with hardreset...

I noticed the same in the manual of the 17-70 C lens. Always used without bothering to switch of the OS. And yes you will eat the chattering noise of the OS every shutdown.

Now if you have the OS switched on and turn off on the M6 the camera becames inoperable till get that chattering noise, that is approx 1 min... Or remove the lens or battery...

Strange is that if I have the OS switch off just before shutdown I ear the chattering noise immediately and can turn on again the camera immediately.

10/4 I wasn't sure if you were use and adapter or found a sigma lens already adapted to the canon camera. This also tells me that if you're using the adapter, there could be an issue with this also. But lets find out what sigma says GL

I received for portugal representative a reply asking to send the lens for verification, that I will be glad to do if they have a solution.

i pointed them to this post (https://www.dpreview.com/forums/post/58907564) where a user reported that Swiss Canon rep. said (in January 2017)

"As you may know our lenses are optimized to DSLR cameras. So there may be incompatibility issue when it attached to Canon M series cameras. In other words, our products to not support Canon mirror less cameras." (...) "We are sorry we could not give you any better news."

So I'm waiting for the new reply to understand if there are any solution nowdays.

In the meanwhile I did some research in the foruns and found out I'm not close to be alone with this, so open a post regarding several SIGMA lens with this problem here:

Hope to call attention to more users and possible sigma regarding this.
 
Appreciate the update. Very useful to those who may try to attempt the same configuration. Sorry to say, I've never been impressed with some aftermarket lenses. Though I hope one day to acquire a zeiss for the canon.

I used my new Sigma 100-400mm this week at a local zoo. I left the OS switch permanently on, even though I turned the camera off and on several times during the day. I had no problems and neither did I hear any chattering noises. All good.

But I've just remembered that I have Continuous Autofocus switched off. The default is to have this switched on and I wondered if those users who have this "chattering" issue all have Continuous AF enabled.

To be clear, Continuous AF is a feature that causes the lens to focus continually, even when you are not half-pressing the shutter button. It is designed to get focusing approximately right all the time, so when you do press the shutter button the focus is already in the right ballpark, and full focus is therefore aquired more quickly. In practice it's not always helpful and it's a real battery drain, so dome people turn it off. It's a menu setting.

I realise that focus and OS are two different things, but it occurs to me that their operation may be linked. If you are getting the chattering issue consistently, you could turn off Continuous AF as an experiment. The issue might just disappear.

I always deactivate that continuous AF. It's not related with this issue. Canon changed the method of OS control in M3 and newest ones, and some sigma lenses models are affected.

I did some research and didn't find any report regarding this issue with the 100-400mm C.

Thanks for your feedback/report

I was not able to solve this problem when I was using this lens with this body. I owned this lens, liked it paired with my 100D and then used it on my M6 eventually. Ran into such problems too. Sold both the body and the lens a few years ago.

An user (@nnowak) explaind the following, this could be the reason for the problem that some SIGMA lens have in combination with >M3 cameras:

When you adapt an EF or EF-S lens to your M2, both AF and IS will activate with a half press of the shutter button and then later time out. This behavior is identical to a DSLR. Starting with the M3, Canon changed their programming and now the IS mechanism activates as soon as you turn on the camera. The IS never times out and will continue whirring away even if you are in image review. All subsequent M series cameras are affected by this issue and it appear the new EOS R is affect too.

So I did some research in the forum and found that I'm not alone and there are other lens that suffer from this problem. The most affected SIGMA adapted lens on M with reported problems are the following, but could exist more:
  • Sigma 17-70 F2.8-4 Contemporary 013
  • Sigma 17-50 F2.8 OS HSM
  • Sigma 18-250 F3.5-6.3 DC MACRO OS HSM
  • Sigma 150-600 F5-6.3 DG DN OS Sport? or Contemporary?
Here are some reported cases in the Forum of irresponsive camera after shutdown with OS selector ON:
  • M6 + Sigma 17-70 F2.8-4 C 013 (USER: Toze3)
  • M5 + Sigma 17-70 F2.8-4 C 013 (USER: Specialbiker)
  • M? + Sigma 17-70 F2.8-4 C 013 (USER: jcm65)
  • M3 + Sigma 17-50 F2.8 OS HSM (USER: Oliver Bedford)
  • M5 + Sigma 17-50 F2.8 OS HSM (USER: amenamen)
  • M5 + Sigma 17-50 F2.8 OS HSM (USER: borno)
  • M5 + Sigma 17-50 F2.8 OS HSM (USER: Dshae)
  • M5 + Sigma 17-50 F2.8 OS HSM (USER: jacoblee)
  • M5 + Sigma 17-50 F2.8 OS HSM (USER: MSega)
  • M5 + Sigma 17-50 F2.8 OS HSM (USER: Woodman411)
  • M5 + Sigma 17-50 F2.8 OS HSM (USER: Specialbiker)
  • M5 + Sigma 17-50 F2.8 OS HSM (USER: Burner100)
  • M50 + Sigma 17-50 F2.8 OS HSM (USER: Burner100)
  • M3 + Sigma 18-250 F3.5-6.3 DC MACRO OS HSM (USER: Scooterch)
  • M3 + Sigma 18-250 F3.5-6.3 DC MACRO OS HSM (USER: Runnicle)
  • M3 + Sigma 18-250 F3.5-6.3 DC MACRO OS HSM (USER: MikeJ9116)
  • M5 + Sigma 18-250 F3.5-6.3 DC MACRO OS HSM (USER: Scooterch)
  • M? + Sigma 150-600 F5-6.3 DG DN OS S/C (USER: ptrhns)
I would like to know if there are more with this problem, and hoping that this could take some attention of Sigma to solve this out.
