I often hear people claim that image-stabilization is only of value on normal to long focal length lenses, and is not useful on wide angle and ultra wide angle lenses.

The photograph posted earlier today was shot handheld on a full frame DSLR at 1/25 second at ISO 800 and 32mm. (32mm on full frame is equivalent to using a 20mm focal length on a 1.6x cropped sensor body.)

I had just finished a session of tripod-based landscape shooting on the summit of this dome, had packed up, and was heading down when the lone hiker crossed the ridgeline below me just as some lovely post-sunset light gently illuminated the landscape. Having no time to set up a tripod – hiker and light would have been gone by then – I dropped everything, pulled the camera with image-stabilized 24-105mm lens from the pack, made some quick seat-of-the-pants exposure calculations, and got of three quick frames before the scene was gone. Without IS I simply would not have gotten a usable version of this photograph – a photograph that has since been licensed for use in a print journal.

Even as one who often shoots from a tripod – and almost always carries one – I have found the notion that IS has no value at shorter focal lengths to be a myth not born out in actual practice.
