IBIS is generally most effective at focal lengths under 200mm FULL FRAME EQUIVALENT FIELD OF VIEW. ILIS is generally most effective at longer focal lengths.


That's old history. I use Pentax and for the last couple years, at least, they have settings that cover from 8mm to 2000mm.

I have successfully used my 60 year old 500mm, (with x2 sometimes), at the moon, stars, and birds while trying to be very still and hand held.

Several manufactures already have or are switching to in body stab because of it's great ability. Even the mirrorless Nikon Z series has switched to IBIS.

using a Canon manual TS-E lens with Metabones adapter on Sony a7R iii: does IBIS work on a lens like this ?


Does your metabones have the contacts that feed info to the camera, if it does it should work.

Download the PDF file to your smartphone, tablet, or computer. Most of them are hypertext-enabled, searchable, and very easy to use, compared to printed versions.

The very first thing I've done when confronting a new camera — since borrowing a friend's Canon FX in 1968! — is Read The *Fine* Manual. Yes, they get longer and longer as time goes on and tech evolves. No, you don't need to know everything to make good use of the camera. But if you want to know about all its tools, and how to use them, it's most helpful.

A complaint often heard is that, "The manual doesn't answer why I might want to use a feature." That, friends, is why you turn to general courses, literature, and videos on photography.

Fortunately, the sheer volume of information available, and the abundance of good Internet search tools, makes that task relatively easy. The HARD part is dedicating the time and focus to it, and caring enough about photography in the first place to motivate yourself to do that.

First, you have to figure out how the engineer indexed / named the task you are searching for ( like in a car manual ). Second, with the vast audience in UHH with its vast knowledge, I almost always get a virtual response to my query, and, often receive ancillary information I would not otherwise receive. Sometimes, of course, the response is much more in detail than I would want; having said that, the variance in responses often means someone will find the meaningful response he / she is looking for- you can skip the responses you really don't want to deal with. I have sometimes managed to avoid buying something I didn't need or really didn't want because a respondent said something as part of answer.

Fair enough. However, as any dedicated researcher will note, attention to primary sources is usually the best resort. UHH has a lot of good authorities and notable, useful viewpoints, but caveat emptor! There's a heap of brain excrement here, too!

I cannot say enough about the UHHers, and their willingness to respond and chime in; the only time it becomes burdensome is when someone is condescending, or interjects ( however lightly ) a political overtone. But if you want to get right to the point, this is the place to come to / query. And, it is true, what seemingly might appear to be good information might really only be an opinion, per se, or an individual's analysis.
