IS working?

Darla80828 · Jul 16, 2003

I have the Canon 28-135 IS lens, and it seems to work great. I used to own a Olympus C-2100, and I knew when the Image Stabilizer was working. How can you tell that the Image Stabilizer is working on the Canon lens? With the Olympus, I could see the picture freeze right before writing it to the disk. But, with the Canon, I don't see any of that. I'm sure it's working, since I don't see any camera shake, but I was just curious. To me, the lens works the same as the Canon 50mm F/1.4.

Am I missing something, is the IS silent enough that you won't even notice that it's on? How long do you have to hold down the button for the IS to kick in? I hold the button down for focusing, and wait till I get that green light, is that enough time for the IS to kick in?

Thanks for any info anyone has to offer. I just bought the Canon 10D in the beginning of the month, and I'm loving the colors! I used to own a Sony F707, but it died on me, after 1 1/2 years use! Rather than invest on fixing it, I decided to get what I've been longing to have! I old 35mm cameras were a Canon AE-1 and AE-1 Program.

Thanks,

Try turning it off and using the long end (135) focus the camera. You will see shake. Then turn it on. No shake.
Yes it is fairly quiet but makes a little noise. Kicks in pretty quick.

Olympus does not have an image stabilizer. Neither the C-2100, nor any other model. The only camera companies producing image stabilizer lens are Canon, Nikon and now also Sigma.

This is not image stabilizer, rather it is the captured image that is displayed on the screen. If you look at the LCD display of your Canon, you can also see the captured image there for some seconds.

IS is silent, but it is possible to hear it working if you put your ear against it and half-press the shutter. The IS kick-in delay is between half a second and one second. The green light means that the camera has acquired a focus on something, but the IS needs more time for the gyros inside the lens to spin up. After that you can actually "see" the IS working, because the image gets sort of "sticky". If you move your camera, the image in the viewfinder does not follow immediately as it would if you switch the IS off. Try it!

darla's correct, olympus does have a stabilization lens on the 2100. To quote from this site's review of the c-2100:

"the C-2100UZ sports a large 10x stabilised optical zoom lens"

sony also has this feature (steadyshot) on the fd-91, to quote the review:

"One other quite unique feature of this camera is it's "steady shot" optics, straight from Sony's camcorder range this interesting piece of technology actually enables a floating lens at the far end of the lens barrel which automatically adjusts for any camera shake, thus the rather bulbous appendage on the end of the lens barrel (you can of course switch this feature off if you prefer)."

canon, nikon and sigma are currently the only ones to offer this feature on their SLR lenses, but not lenses in general. camcorders have had this feature for some time.

I have yet to see the "sticky" image, so maybe I'm not waiting long enough for the IS to kick in. I plan on taking more pictures this weekend. I will check it all out then.

Thanks for all the great info!

I can't imagine someone saying it is silent. When you half press the shutter you can hear a motor spinning up. That motor is used to position the IS element. Make sure you have the IS switch on! It should be easy to hear.

An easy way to see if it is working is to tripod-mount your camera, zoom all the way to 135, look through the viewfinder, depress the shutter half way and wait about 1 sec.

The IS does NOT like to sense NO movement - impossible in your hands, but not on a tripod. On a tripod, you'll see the entire image start to drift in the viewfinder as the IS tries to "correct" for what it erroneously senses as a slight acceleration in the opposite direction.

As for the image on the LCD - on the Canon it only shows up there AFTER you take the pic. Not like the Oly, where you see it before (live) and after (the captured image.) A really nice feature of the Canon over the Olympus (well, over my old E-10 anyway) is that during the time it is on the display you can delete it if you want - without having to switch to play mode. Useful for known botched shots.

I can't hear the motor or see the "sticky" image either with the same lens. I think that I see less shaking with IS turned on and have tried some tests with a 0.5 second exposure @ 135 that I think is better with IS turned on.
