IS quality in E3 ?

Image Stabilization quality in E3 :

Recently i got E3 with 12mm 60mm.

Olympus annonced E3 has a 5 stops IS , anybody feel it's true?

i felt E3 with 12mm 60mm lens, has the good IS quality (atleast 3 stops).
but how about in third party lenses, specially sigma 50mm 500mm.

if anybody have any idea , please share that....

thanks, senthil....

Hi Senthil

I find it very hard to quantify how many stops you can get with the IS.It is very effective.

Here is a shot of the moon with the 50-500 and the EC14 at 100th of a second at F10 handheld.Total focal length 708mm.

This was handheld at 1/25 and 200mm.

Re: IS quality in E3 ?

I don't feel like I'm getting anywhere close to 5 stops. However, often by the time I "need 5 stops" the motion of my subject is enough to make IS ineffective. My subjects are not fast moving but they are often living (my nephew, or a flower on a windy day, a dog, ...) very little still life....

Re: IS quality in E3 ?

I am not sure how scientific it is but I used the following method to evaluate the IS performance of my E510 when it was new. At least the results are repeatable and in line with the manufacturer’s claims

1. Using any word processor prepare a document comprising several lines of identical text, in a range of font sizes – say 10point, 11pt, 12pt, 13pt and 14 point. Print it out and attach to a wall as a target

2. From a steady chair photograph the target using a fast shutter speed and the lens set to 50mm. Adjust the distance of the chair from the target until the 12point line is legible but the 11point line is not. My guess would that the chair will now be between 4 and 5 metres from the target.

3. With IS turned off reduce the shutter speed until the 12point line ceases to be readable. Note the shutter speed (say 1/100 second)

4. Turn the IS on and reduce the shutter speed again until the 12point line just ceases to be legible. Note the shutter speed again (perhaps 1/6 second)

If your measurements are in fact 1/100 and 1/6 secs. then you are getting 4 stops advantage from the IS. If they differ you can work out the advantage you actually get.

It might be sensible to adjust the lighting so that the lens never uses an aperture smaller than f11 – below this the performance of the lens may well drop off (due to diffraction effects) which might confuse the results.

When I made the measurements using my E510 and the Oly 50mm f2 lens I got between 3.5 and 4 stops which compared well with Oly’s claim of “up to 4 stops” If you do repeat the experiment with an E3 I will be very interested to hear the result.

Re: IS quality in E3 ?

Thanks for all of your replies,

Andym your picture is unimaginable quality....with 2x TC ..

Picture focal length is near 700mm it convert into 1400mm with handhelded in the shutterspeed of 1/100th sec.........

I think, this picture and this detail is good & amazing advertisement for OLYMPUS Quality.....

Dear Mac, you mentioned perfect test...

Sure i will test that with my E3..... and post the results.....
