sturkel Posted March 28, 2019 Share #1 Posted March 28, 2019 Advertisement (gone after registration) So wondering how the auto mode decides to come into play or just better to leave on all the time unless using a tripod. Why not leave on all the time? Any thoughts would be appreciated cheers Link to post Share on other sites More sharing options...

I am using Auto setting. 3 Link to post Share on other sites More sharing options...
sturkel Posted March 29, 2019 Author Share #3 Posted March 29, 2019 So I am curious not much of a reply to this question. I reviewed the manual and there is very little info on this topic. When does the Auto setting kick in and what shutter speed? No mention of image degradation when left on. All of my other cameras have much more info on the subject and the only warning has been when using a tripod. Any feedback would be helpful.

Cheers AFAIK, no other camera has Auto setting for image stabilization. An older discussion thread mentions: Link to post Share on other sites More sharing options...
sturkel Posted April 1, 2019 Author Share #5 Posted April 1, 2019 Good point as I don’t remember seeing auto IS on my Sony or Olympus cameras. The Nikon was on off on the lens . I think default is auto btw on the Leica. Just wondering how it opeates in auto mode. cheers Link to post Share on other sites More sharing options...

On Leica Q/Q2, Auto stabilization mode means that the camera decides when to switch stabilization on/off. On Olympus, Auto stabilization mode detects the panning direction and applies appropriate stabilization. Link to post Share on other sites More sharing options...

In Olympus S-IS 1 setup means auto stabilisation and it kicks in when needed. S-IS Auto means the panning detection and restricts the stabilisation depending how you pan the camera. You can easily detect when S-IS kicks in by the humming sound the sensor makes. Link to post Share on other sites More sharing options...
ricky1981 Posted April 1, 2019 Share #10 Posted April 1, 2019 I thought I'd read somewhere that Auto kicked in around 1/30s, maybe someone can try setting the shutter speed manually to determine when it comes on? I intend to leave it on Auto since I very rarely shoot on a tripod and that tends to be the only time where I've noticed IS worsening image quality since it seems to get confused by the total lack of vibration.

The manual for OMD-E M5mII says: S-IS1 - All Direction Shake I.S. - Image stabilizer is on. There is no mentioning that S-IS1 mode switches the IS on and off depending on the shutter speed. At least, the intention of that modes is not to be used as the Auto mode on Q/Q2, I think. Is there any source that confirms your observation?

See this thread where user jmschuh answered the question with some trial and error. He set Auto Image Stabilization on and took pictures at different speeds then looked at the icons in Playback-mode. IS was on at 1/30 sec and slower. I'm assuming the Q2 will be the same as the Q. Given some of the things that are reportedly different that assumption may be suspect.

Is there any source that confirms your observation? Years back there were discussions about this and I tried to find it, but couldn’t use right search words to pick it up. Only commercial stories, not the technical whitepaper I was looking. It’s also possible that newer firmwares have changed the way it operates. At least pressing shutter halfway makes it kick in whenever S-IS is on. I remember this was related to avoiding battery drainage. But, it used to be related to focal length and shutter speed how aggressively S-IS kicked in. But as said, this could have been changed in newer firmware versions.

sturkel Posted April 5, 2019 Author Share #14 Posted April 5, 2019 I did some research and this is what I have found The lens is the same 11-element, 9-group 28mm f/1.7 design as before, which includes three aspherical elements to minimize distortion and peripheral aberrations. But Leica says that it has tweaked the way the lens is built to meet the tighter demands imposed by the higher resolution sensor. Unusually for a full-frame fast prime, it’s optically stabilized, which gives the camera extraordinary low-light capabilities. Leica has included a new Auto OIS option that only operates at shutter speeds of 1/60sec or slower, and otherwise keeps the IS group centered for maximum sharpness. I’d leave it switched on all the time.Read more at https://www.amateurphotographer.co.uk/reviews/compacts/leica-q2-review#pTKj4GLuuFSwyXL6.99 1 Link to post Share on other sites More sharing options...

Quite noticeable at 100%. With IS turned off, the camera becomes a whole different proposition and produces exactly what I paid for. I have been using an M10 since they were released and I was less than impressed with the Q2 images until I discovered this. IS is clearly useful in very low light situations and hand-held video, however I will be using it very judiciously in the future. 1 1 Link to post Share on other sites More sharing options...
sturkel Posted April 13, 2019 Author Share #17 Posted April 13, 2019 Interesting observation. Would you have a sample you could share. In looking at some of the posts here it has not been discussed. As color smearing as you mention. 1 Link to post Share on other sites More sharing options...

I have not noticed any image degradation with OIS active, but I am using it only in Auto mode (engages only at 1/60sec or below). At what shutter speed did you notice the softness issue? 1 Link to post Share on other sites More sharing options...
M11 for me Posted July 23, 2020 Share #19 Posted July 23, 2020 As I just had to find out recently what Auto Ois does I found this old thread. Here it is left that OIS Ato starts at 1/60s which is wrong. It starts only at 1/30s and slower. You can easyly find out by setting to Auto OIS and shooting at 1/30s and the 1/60s. Now you review your 2 pictures on your little screen and show the EXIF details: On top right you see the settings of the OIS. Link to post Share on other sites More sharing options...
vedivv Posted July 24, 2020 Share #20 Posted July 24, 2020 It is actually easy to know if OIS is running. If you toggle full display mode, the OIS icon appears if OIS is operating. And when you are in playback, the icon on top right also shows OIS status. Auto OIS kicks in at 1/50 (1/60 would not activate OIS). I would definitely keep OIS on auto. I have been consistent taking sharp photos with 1/15 shutter when OIS is on, and even 1/8 can get very sharp pictures but with perhaps 30% keeper rate. I don't think 1/4 with OIS is really usable, especially given the 47MP sensor. Leica is probably right that OIS might slightly reduce IQ, but I could not find much IQ variation with controlled experiment (on tripod) with OIS off and on. But that's probably a moot point with auto OIS. It is off when shutter faster than 1/50. You would need it anyways between 1/8 to 1/50 handheld. So the OIS reducing IQ is only a real issue if you are using tripod and shooting long exposure. And if you go through the trouble using a tripod, you probably don't mind manual turn off OIS. My solution has been creating a tripod profile with OIS turned off. 2 1 Link to post Share on other sites More sharing options...
