I received the 0ly 100-400mm yesterday. After doing some routine handheld sharpness and IS tests, which i've done many times, my conclusion is sharpness is pretty equal but in my hands the OIS on the Pany 100-400mm is better than any combination of IS settings that can be used with the E-M1 MK111 + OLY 100-400mm lens. I will miss the advantage of being able to use the 1,4x TC but I'm 74 and IS is the most important thing to me. The lens will be returned to Amazon after the bank holiday.

Wow, this sounds rather disappointing! I'd expected the Oly to perform better in terms of IS than the Panny on the latest oly body.. Thanks for posting.

kitty, these were taken on G9, so dual IS would offer a (slight?) boost in stab. to the PL over the sigma. On an Oly they may be 'a wash'.

Remember, OIS would almost certainly be the best option at 300+mm end. I'd expect IBIS (on recent bodies) to be much better below , say, 200mm... but that is a guess.

Thanks but I was referring to klythawk's comment about using the 100-400 on the EM1 mkiii and IS not being as good as the PL on that body, not the OP using it on a G9...

Cheers

To me, the information on how the Olympus 100-400 lens IS complements the in-camera IBIS of the E-M1 III is really confusing. If I read it correctly, the combined lens and IBIS is less effective than the IBIS alone.....if this right, or am I missing something?

Gary... it DEPENDS !

1) individual habits / shooting techniques impact on Stab

2) Stab effectiveness is focal length dependent (OIS eclipse IBIS @ long tele)

3) Dual IS therefor matters most at long end of lenses

4) IBIS tech is much "newer" than OIS, w/ dramatic progress

5) 'everyone' wants to demonstrate that theirs is best

6) it seems that smaller sensors benefit most from IBIS                                                                  (but Canon R5/6 may be exception?)

*Certain reviewers (Richard in NZ) give us very 'scientific' tables showing exact benefits of IBIS and Dual IS
