I have three lenses:
100 mm Minolta macro AF
24-70 Sigma AF
70-300 Sigma

With none of them I see any effect in any picture, when setting the Antishake of my Dynax 7D in the ON position.
Are they all not compatible? Is my camera difect?
Thanks. Roberto

Hi Roberto,

can you please post some examples?
You can use our gallery, if you don´t have your own webspace -> Link

Do you see the five green signs in the viewfinder when AS is ON? They signal you how effective the antishake works. If only one sign is left, the picture is stabilised.

At which exposure times you made this experiences?
Give more details.

Thank you for your answer.
It seems I was asking too much stabilization to the stabilizer!
It works only when you are already very stable and with reasonable exposure.
If I do so, the picture with and without stabilization look almost the same in the camera LCD screen, but when you see them in the computer, the picture stabilized is 100% sharp while the other is not. When I go over 0.5 second exposure (aperture 8) or I am not very, very stable, the picture starts to look unsharp, even if it is stabilized. So there is a certain limit.
Is that also your experience?

0.5 seconds exposure time?!?
Roberto, Antishake gives you a benefit of about 3 apertures. So, for example if you could handheld an exposure time of 1/30, AS will help you to get down to 1/10. But not more.
AS is no miracle, it´s just physics.

Sorry Jerichos, you are a little bit wrong !

It's late in the afternoon and my mathematics is as worth as my english CORRECTION:
If you have an exposure time of 1/30 and the benefit of AS is 3 aperatures you will get an exposure time of 1/4

You forgot to translate your signature into a plane English.
Remember: drcaste speaks English only.
