Does GP-E1 influence IS ?
« on: October 10, 2012, 05:44:02 PM »
Hi,

I have noticed something strange. 1DX, GP-E1, 70-200 II with 2X.

I had the camera at a 45 degree angle, so half way between landscape and portrait, the IS system was making noisy and I was unable to auto focus.
I switched the camera off , back on again --> everything fine, up to about an hour later when I was pointing upward to take a shot of a bird high in tree.

It looks like that at certain angles ~ 45 degrees the GP-E1 gets confused.

I tried without the GP-E1 and I am unable to reproduce the "problem"

My questions:
1) has anybody had the same problem?
2) is the GP-E1 info used for IS?


This is a minor problem, just switch camera off on and it is solved. I am just curious?

Regards,

Ben

Hi,

it happened with 1.0.6

Since, I have upgraded to 1.1.1 and have not been able to reproduce the problem.

Thanks for your interest

Are you sure it was the GPE1?
If your lens was set to Mode 2 IS (ie, panning in one direction only), then the IS would get confused as it doesn't know which way is up if it's at 45 degrees...
Too much gear, too little space.
