Serge Teulon Posted October 20, 2009 Share Posted October 20, 2009 Just to add to Stephen's response. It gives an impression that zooming has taken place. It's also a sign of a cheap lens. But as with everything, if used in the right way it becomes a creative tool. Link to comment Share on other sites More sharing options...
Premium Member David Auner aac Posted October 20, 2009 Premium Member Share Posted October 20, 2009 It's also a sign of a cheap lens. And many older, not so cheap zooms! Also breathing usually more prominent in still lenses as this doesn't really matter for photography (well sometimes it does, but not as much as in cinematography).

Dean Werner Posted November 19, 2009 Share Posted November 19, 2009 In my experience the term lens breathing is when the camera tries to focus on its own. In the manual mode it would try to pull its own focus and the focus moves like a breath for a bit. This is on the XL-1 though and I was told was because the camera needs to be cleaned.

Rob Vogt Posted November 19, 2009 Share Posted November 19, 2009 I never heard that use for the term Dean. I also experienced a lot of breathing today on a very old 12mm Zeiss prime. Link to comment Share on other sites More sharing options...

That's not breathing, more like short-circuited electronics. Or, it could be called self-instantiated auto-focus hunting with quantized focal drift positioning.

Also breathing usually more prominent in still lenses as this doesn't really matter for photography (well sometimes it does, but not as much as in cinematography). Regards, Dave It's extremely common on most of modern SD & HD video lenses. It's usually the wide angle zooms that tend not to have breathing as a built in feature. Although perhaps there it's reduced to not usually noticeable level. i.e. you have to look for it. Link to comment Share on other sites More sharing options...
