Canon 100-400 L Is On A Tripod?

Sun Nov 07, 2004 3:41 am

Hi everybody!

In a review of the Canon 100-400 L IS at http://www.luminous-landscape.com/reviews/lenses/400v400.shtml
I have just read that the IS of this lens cannot be used when mounting the lens on a tripod. The IS of the 70-200 L IS on the other hand can. What is the reason for this? Where is the difference in the two versions of the IS? Are both equally suitable for spotting?

In case this subject has already been covered in this forum please post the link.

Thank you very much already for your help! Best regards,

mfz

Not sure what they are talking about. My Canon 100-400mm IS has a tripod collar that works just fine...

Perhaps others can confirm or correct me, but I think the 70-200 has a newer generation of the IS system, which obviously (as luminous landscape states?) can be mounted on a tripod with IS switched on. The 100-400 could get confused if IS is switched on when the camera is completely still, causing IS lens-group to shake. I have not noticed this yet, but people with the 100-400 have been advised (informally, I don't know what Canon has said) to switch off the IS when taking shots from a tripod. Which isn't a problem really, since you don't need IS on a tripod.
Cheers,
Eduard

The manual of my 100-400 does say to shut off the IS when mounted on a tripod, the gyros may cause movement and hence give a blurred image. Unfortunately not owning a 70-200 IS I can't comment  Sad

I can't see why you'd need the IS turned on if the tripod was stout enough to hold the equipment still enough..?

Respecting my 300/F4 IS the manual says I have to switch the IS off in case of tripod used...Opossite to this recommendation I've read in this forum that you can use it with no problems...

Colin...are you there? We (all) need your help... Big grin

I use the 100-400L IS lens on a tripod all the time, with IS on. Not for spotting though. I leave IS on and don't use a tripod for aircraft. More for wildlife. I never noticed it freaking out on a tripod. When it does gyro shake is when it is not on a tripod, and I am following an aircraft at 45 degrees. It doesn't know if it is going side to side or up and down. So it shakes and makes a hell of a racket. For a quite camera anywy.

@ all

Thanks a lot so far for your help! Your comments cleared things up a bit for me. I also assumed that you wouldn't really need the IS when using a tripod, but I just wanted to hear some experiences from people with more expertise in this field. But I guess essentially it comes back to "trial and error" with each lens to find out what happens.  Smile/happy/getting dizzy I don't own the lens yet but I am very tempted to get one really soon...

@N317AS

Your comment about the IS freaking out when you tilt the camera (and thus the lens...) to a 45 degree angle however was quite interesting. Good to know that in those cases it might be better to switch the IS off.

What about using the lens with a monopod?

You don't have to switch off IS while using the 100-400L on a tripod. You're supposed to put it into IS mode 2 which only stabalizes on the X axis, as opposed to mode 1 which stabalizes on all axis. I don't quite understand the rationale behind that but that's what the manual says.

Likewise for the 300/4L IS. Most of the newer generation IS lenses do sport the dual modes, unlike the older ones.
