EOS 3 and Image Stabilization

With the EOS 3 and an image stabilizing lens, does the camera automatically adjust to the slower shutter speed to take advantage of the IS feature, or must the program be shifted? If it must be done manually, any recommendations as to the best and fastest way to do the shift accurately?

Hi Scott: At least at this time, EOS bodies do not "recognize" an IS

lens and behave any differently than with a non-IS lens. Don't think

that just because an IS lens allows hand-holding at slower shutter

speeds that you should go out of your way to shoot at those slower

speeds. Think of IS as an "internal tripod" that's there when you

need it. I usually use my 300/4 IS (when in IS mode) with or without

the 1.4 TC in aperture priority, wide open. This MAXIMIZES shutter

speed, but if/when the shutter speed starts dropping, I know I can

still handhold with confidence, often to 1/30th or sometimes even

1/15th sec. The beauty of the IS lenses is to help free the

photographer from the confines of a tripod; it does not, for example,

magically transform an f4 lens into an f2.8 lens. It only allows one

to confidently handhold a lens at speeds slower than 1/focal length.

Other than this, an IS lens is not much different than a non-IS lens.

Thanks for your answer, Kurt. I shot a test roll today with IS on and

off. I used 800 speed film and indoor light with the camera on AV.

The shutter speed was approx 1/40. I did not hear any noise at all on

the 28/135 IS lens when it was operational. I think I can tell a

very, very slight difference in the focus, but without a loupe it's

hard to tell if it made a difference. I will try again tomorrow and

use a rheostat on the light to get the shutter speed to 1/30 and

lower to see if the lens is working in IS mode.

I will be using the lens indoors for events where a flash would be

prohibited or draw away from the main speaker. The orange tinge to

the picture from the light is marked. Is there a filter that would

work best to eliminate this cast? Thanks, Scott.

Scott: Take a look at Jeff Hallett's posting on the Q&A forum from

7/26/99--it's still listed as an active question toward the bottom of

the Q&As. You may find the responses helpful.

Addendum: Scott--It sounds like the orange cast you're describing may

be due to a tungsten light source such as an ordinary light bulb. To

correct for this, you can either.... what's the answer? Delve into

the static contents here at Photo.net, and read about light as well as

filters, and you may discover the information you seek. Also try

doing a search using (for example) the word "tungsten" and see what

comes up. Give us a holler if you get stuck. Happy learning!
