problem w tym, że jest kilka typów IS.

One advancement that Canon has included in this latest generation of IS lenses is the ability for IS to work even when the lens is tripod mounted. This is very worthwhile since even a tripod mounted lens is subject to vibration. I felt tremendous confidence using this lens under a wide range of conditions.
I jeszcze trochę z tej samej strony:
Some people ask — is IS really necessary when one is using a tripod? The answer is a resounding yes. A 500mm or 600mm lens has 10X and 12X magnification respectively. Even the resting of ones hands on a tripod mounted lens this long causes vibration, and if there's a wind blowing then that's another contributor to camera shake. It needs to be borne in mind that when shooting wildlife, at least, one is usually working in low light levels, early and late in the day, which means sometimes shooting at 1/60th or even slower. I have done this successfully with the 500mm and 600mm IS lenses but not so successfully with earlier long non-IS telephotos.
One other question is whether the 500mm and 600mm lenses can be hand-held successfully because of IS. The answer is, it depends. I don't find the 600mm hand-holdable at all. It's simply too heavy. The 500mm f/4 can be hand held, but in my case only for a minute or so before I start to shake too much. But I do have some successful frames shot at as slow as 1/125sec with the 500mm.
A break of a minute or so then allows hand holding again for a short while. I find that I can hike with the 500mm f/4 either in my hand (carried by its padded combined tripod mount and handle) or using its shoulder strap. The 600mm is too big and heavy for this, at least for my mid-sized build.
Kolega wyzej dal dokladna odpowiedz - najnowszy IS NIE wylacza sie na statywie i NIE musi byc wylaczany.
Wykrywajac statyw przelacza sie w tryb niwelowania drgan statywu.
Tylko za cholere nie moge sie domyslec jak ten IS 'wykrywa' statyw.
wydaje mi sie ze co do tego wykrywania statywu to prostsza rzecza jest raczej jakis czujnik wbudowany w miejsce montarzu statywu z tele.Bo raczej wykrywanie rgan w plasczyznach bylo by zbyt skomplikowane technologicznie... tak mi sie tylko wydaje...![]()
Pkt 8 Regulaminu - niedozwolona stopka tu była...
no ok, to moze byc mozliwe...i bardzo prawdopodobne, ale co w przypadku (teoretycznie) - supertele ktore wykrywajac statyw same wyolaczaja IS - jezeli polozymy go na jakims podlozu, sam wylacza ten system, czy IS nadal jest aktywny.(Pytanie w czystej toerii, bo w takich wypadkach IS nie jest chyba potrzebny)
