Default On lens IS vs In body IS

I am wondering if I turn off the in body IS on the E-PL1 and be able to use the on lens IS on a Panasonic 45-200mm lens. I have read something on the other forum that I have to turn off the on lens IS in order for this lens to work on the E-PL1 camera.

I have the EPL1 and the 45-200mm. I never remember to switch the OIS off on the lens when I use it on the EPL1 and have never noticed any issues. Actually, the EPL1 produces sharper images at 200mm then the G1 did. But, I never really tested with and without OIS turned off to see if it makes any difference. I think it might depend on the type of photos you are taking and how you are stabilizing the camera.

In the setup menu, there is choice of I.S.1., I.S.2., I.S.3 and OFF. That's why I want to know if if IS on the lens will work with the IS function on the camera is turned off. I know that the Panny lens will work with IS turned off on the lens.

I would not turn off the IS on the camera because you may forget to turn it back on. The nice thing about the IBIS is that it will work with any lens. It's a lot easier to turn off the OIS if you are concerned about having both turned ON.

That makes sense by leaving the IBIS on all the time since I am not getting any younger. I simply want to find out if there is a difference in performance between IBIS and OIS on the long end of the 45-200mm which should be delivered end of next week.

I haven't tested the various possible combinations (perhaps someone else has). Like I said, I use the combo with both IS ON and it seems to work fine. I suggest you pick a far away subject and test all 4 combinations to see which one produces the sharpest image (take multiple shots with each combination just to make sure that in case you get an image that's OOF, it's not because of the IS combination but simply handshake).

I read in a review which says the OIS is on all the time cannot be disengaged. Effectively with a camera like the Olympus Micro 4/3, both on lens and in body optical stabilizers are on at the same time and all the time unless one chooses to turn the the one in the body. This is what it says in the last part of the conclusion:

"The build quality of the lens is very high. The OIS (image stabilizer) is pretty efficient in field conditions and it can give you an extra potential equivalent to about 2-3 f-stops. We'd like to see a really deactivated OIS in non-stabilizing mode but, to be honest, most users will not disable the OIS anyway. All in all quite good lens with a sane price tag. "

Hum...I don't know about that. The 45-200mm has an on/off switch on the body and I know it does turn off OIS because I had it switched off by mistake once and got some pretty poor images with the G1.

Ois will drain the battery of the pens pretty quickly. And it is not a good idea to have both ois and ibis on. It does funny stuff when I tried it on my 45-200. Also you will drain the battery even faster.

The oly ibis is very effecT. It is good upto 1000mm. It might be a lit bit less effective then a ois system. But the different is mynut amount. I have just given up on the ois, just use ibis with the panny lens.
