OIS at fast shutter speeds up to 1/8000 second.

[miguel]

I have always been convinced especially with my Nikons that you should switch OIS off at shutter speeds faster than 1/250 or 1/500 sec.

 

Well today I did a serious test with my 50-140 zoom with a TC1.4 attached.

 

I shot at f2.8 on the lens, effectively f4 with the converter.

 

Hand held, I shot a series of RAW images from 1/500 sec to 1/8000 sec, with and then without OIS on.

My in camera OIS option was set to keep OIS on continuously to keep the EVF image stabilised.

 

On a 27 inch apple calibrated monitor viewing all images at 100%, really pixel peeping, I could not see any difference in these images when comparing the OIS on or off images.

The images had to be compared in pairs because in order to achieve the higher shiutter speeds, the ISO had to be increased for each pair.

.

I was quite surprised how good the converter was shooting at f2.8 but thats another story.

 

I would appreciate any comments on the fast shutter speed syndrom. Perhaps Fujis are not affected like the Nikons?

I've read some online fora about turning off OIS if the lens is being transported in a vehicle, blah, blah, blah.   I never ever (except when on a tripod) turn off OIS.  Heck, I've even left it on while on a tripod.  Effects:  None whatsoever.  I'm sure if someone did a scientific test, at various shutter speeds someone somewhere would actually see a difference.  Me?  Meh.  Honestly, I try to remember to turn OIS off when shooting at high(er) shutter speeds, but I usually don't so...  No ill effects here.
