Ross,
I know this problem as I have a Canon 7D with 400mm lens and no IS so I have to hold it very steady, with the E-M5 this caused problems with the IBIS originally, but I've now conquered that. However the techniques used with the E-M5 don't work with the E-M1 at the moment, but I will beat it!

I will do but as I am off to foreign parts tonight I don't have time at the moment - but when I get back!

But it doesn't with the E-M5, although when manual focusing I switch IS of before shooting.

Re: IBIS Question?

A question - how on earth did you "run in" the IS on earlier models?

I tried it when it was new on the E-3 and E-5 and found that neither worked for my hands. Rather than continue letting it ruin photos I just switched it off and carried on without it. The E-M5 was a different kettle of fish, it worked so well straight out of the box that I leave it switched on. I am a bit mystified how you would use it enough to stabilise its behaviour without losing a lot of the photos that you wanted.

Ciao ... John

OK. I know it does with my E-3 and also that Olympus recommend switching it off on the E-M5 (and the E-3) when using a tripod. (page 49 of the E-M5 manual)

I don't know if this has any relevance, as I've only had around an hour shooting with my new EM-1, but with the 75-300 on the front it felt much less stable than on the EM-5

I think this is down to the lack of inertial mass of a battery grip (always attached to my EM-5) and I have had to modify my holding / tracking techniques slightly to get more comfortable with the "Naked" EM-1.

Hopefully I will get my grip soon and will be able to confirm this

Off to evaluate several hundred shots from Mudeford Quay, then I will have a better handle on the IBIS (and a lot of other factors)

Do you really get problems with shock when photographing the moon? The last time I photographed the moon I was using ISO 200 and at f/7.1 the shutter speed was 1/1000th.

Mirrorless cameras have a lot less shock issues than DSLRs because there is no mirror to flap around and the E-M1. E-M5 and E-P5 all have superbly dampened shutter mechanisms so I really doubt that shutter shock is an issue.

Re: IBIS Question?

I really doubt that there is a 'run-in' issue with E-M5/E-M1 and E-P5 IS (these three camera models all use basically the same electromagnetic 'voice coil' induction system). When activated the sensor is basically held in place by a set of magnetic fields that are adjusted by accelerometers inside the camera. There is very little mechanical/friction componentry that might need to 'run in'.

Re: IBIS Question?

I agree with you Ian, I've had a slightly more detailed run through my images (from which I will put a selection, good and bad up on Flikr) and I am pretty much convinced what I am seeing is the effect of my technique rather than any fault in the camera.

Its hard to see anything mechanical or electronic that would cause what, for me, is a pretty random outcome of sharp or blurred images, one after the other in a sequence

Re: IBIS Question?

I've uploaded a quick selection from my first, 1 hour, test shoot using the Oly 75-300 with IS1 enabled, all hand-held

Here: http://www.flickr.com/photos/7544509...7636326619725/


As you can see (assuming that my EXIF remained intact) I can get sharp or blurry images at a wide range of shutter speeds (from 1/200th up to 1/1250th) so I am more than ever inclined to blame my technique, not the IIBIS system.

The .JPG images (which these are) seem to need a lot more sharpening in from the base setting (everything = 0 in the camera) than the EM-5 did, but I like the results it is capable of producing, smoother and more detailed were two of my first thoughts when processing

A lot more still needed to complete my evaluation, which I will eventually blog

edit - only one of these shows any real blur, don't know what happened to some of the others. Please come back later to see those (I'm cooking dinner tonight - as my wife has just reminded me, time to stop playing! )

Re: IBIS Question?

Olympus responded to some feedback that camera JPEGs sometimes looked over-sharpened with the E-M5 and now the E-M1 will sharpen according to the requirements of specific m.Zuiko lens models, so some will be less sharpened than before.

Re: IBIS Question?

Brian, have looked at the gull shot and it looks over-sharpened to me; there is a distinct hard-edged halo.

This might be something to do with Flickr, maybe, but thought you should know.

Thanks Ian, its possible as these haven't had any time spent on them.

Is it all or one specific one?

(I had read about the lens specific sharpening improvement in the EM-1, nice work Olympus, as with the CA and distortion adjustments )
