I have the Olympus E620 set up with a M42 adapter with AF confirm and currently a Super Takumar 55mm f2.
Hand held and at a shutter speed of approximately 1/40th with the IS switched 'OFF' I get a reasonably steady image. However if I turn the IS to 'IS1' and take a photo with the same setting the image is very blurry as if shot say half a second.
I have tried the IS focal length setting at both 50mm and as a random thought at the 2x factor of 100mm but this made no difference.
If I put the kit lens 14-42mm on the IS works as it should.
If I am not mistaken although the IS is built into the body and therefore shouldn't make a difference which lens is attached.
Any thoughts or links to similar posts would be much appreciated.

Although I do not know exactly how it works Olympus IS, I'm almost sure focal length influences functioning of IS, because different lengths need different adjustments (IS should recognize body movement, but amplitude needed to compensate depends on focal length). However I do not know why you are not able to set it in the right way. Waiting with interest for explanations...

Read the manual, it clearly states that for a manual lens, the focal length has to be manually given. There is a menu for it.

I have found that if the M42 adapter has a 'software' focal length adjustment, it makes a big difference in focus. This, of course, makes a zoom lens a bother to use. This is based on my experience with an adapter with the focal length adjustment on my E-510. |

maybe order of operation: before or after putting the lens or so (I'm just guessing).

If you are using the Dandelion chipped M42 adapter--
http://f22plus.wordpress.com/2009/08/12/dandelion-chip-with-olympus-e-510/
I believe this type adapter overrides the manual setting within the camera and presents the M42 lens as a native lens. |

what a hassle all that seems
for hand held I do the following
- I attach the lens and set the focal length
- set to Manual or Av
- adjust the aperture on the lens (this does not relate to the cameras lcd)
- with the lens stopped down I focus the lens, camera set to SAF as this give a 'beep' confirm.
- if the using small apertures I stop down after focusing and composing
- take the shot |
