ok dumb ? here but i need help qucik

i rented a canon 28-135 is but it didnt come with the book, is the IS on when the switch is set to the I spot of the o spot it didnt come with a book and i dont know help help help thank you

"I" is on, "O" is off. Have fun with this lens. I find that it is much better than its reputation, especially if you make sure that the focus looks sharp in the viewfinded under low-light conditions. If I am hasty taking shots in lower light, the AF will not always be great. In bright light, it works great.

thanks that what i thought just doesnt seem to be working still getting blurry pics

Youn should be able to barely hear the IS engage when you half press the shutter button and it will stay on (audibly detectable) for two seconds after you release the shutter button.

dont hear anything although i havent been listening ill have to try that

I could never really hear mine unless it was struggling, i would think that if you've been shooting for awhile that you have your camera set up for a shot that wouldnt make the IS wind up to much (i.e. fast SS). Try shooting at 1/10 of second handheld and see if you can hear it then.

It also takes about a second to ramp up. I never hear it, that's what the books says. At first, I didn't allow for this one second ramp up and a lot of my pictures were soft. Take your time, don't rush and you should get some real sharp shots. One other thing about this lens, if your using a tripod turn the IS off "O".

The international, universal symbols for on and off are also the binary values for them. 1 = on and 0 =off. Just a little triva

The IS will only give you about a stop or two. So at 135 x crop factor = 216. So with IS off you'd need a shutter of 1/200 or fast to not get shake, with IS on 1/60 or faster. I try to stay above 1/80.

thanks everybody im getting ready to try it usually stay ay about 1/100 or better we will see thanks again
