Now with the ZF 85, generic focal reducer, OM1, video mode, c4k 30p, 10 bit HLG H265, I set the ibis focal length at 60mm, sensor shift and digital, +1. The footage is very usable, much better than EM-5 at 50 mm. If I hold my body and arms tight, I guess that the results will be very close to be tripod like or at least mono pod like. C4K 30p is good enough for slow moving subject tracking, like a rowing man. C4K 30p has more details than C4K 60p. Good for landscape. I guess that if I skip the generic focal reducer, the results will be even better. Not to say the unique 120p photo burst mode. Two thumbs up to OM1. I think it is the best deal today for hybrid cams.

zf 85 supposes to be sharp at f5.6 f8, i suspect that the generic focal reducer is the real culprit.

about video quality of the om1, i think that i used zf 85 mf, which somehow dictates the final image quality. the image looks smooth, but not very sharp, even at f5.6 or f8. very suitable for portraiture, especially to ladies. the color is fine. if using m43 sharp lenses, om1 c4k may be very sharp, will test later with my m43 olympus 25mm f1.8.

The video is very cool. On iPad it is clear enough. 5d2 not bad. Ml raw on 5d3 will make you smile. What is the point of a new cam. I bought a brand new OM1 only for its improved ibis for my mf lenses.

Sensor shift plus digital +1, at 300 mm, is very usable.

Maybe this is the key. I remember that I set the focal length in M mode for the 120p burst mode. I will check if the video mode focal length is set up. Thanks a lot.

Thank you very much for your help. For ibis in video, I use M IS 1, mechanical plus digital.

GoPro is fixed lens camera. I have a collection of mf lenses, so I need OM1 for mf lenses.

After adding sharpening, the C4K 60p looks usable, but not as sharp as GoPro 12. The ZF 85mm is set at F8 with peaking on, so the lens should have no issue. GoPro 12 is really good in terms of sharpness and details. OM1 burst 120p is at least as good as GoPro12.

I mean all video modes have this shaking. I remembered that when I used this focal reducer on EM5, my Leica R 50 mm f2 is about 35mm, about x1.4-x1.5. Maybe the OM1 at 50 mm or 60 mm with IBIS is like this? If so, OM1 IBIS is not effective at long focal length. This kind of IBIS performance is about the same as EM5. Not as good as using Canon C300mk1 or FS7 with a Tamron IS lens. At most, they are equal. I have a lot of 100 mm and above MF lenses, this just is not enough. Kind of disappointed. If OM1 has this kind of IBIS performance at long focal length, I don't expect much from GH7 S5 2, etc. This kind of critical information, only when you have the camera, you can test. I don't see from the sheer videos on youtube about this. But in photo 120 p burst mode, as it is less than 1 second, the stabilization is great at 85/55 mm. I will use this mode a lot on OM1. It is the crown jewel. Video modes on OM1 are just not as outstanding.

The 120p photo burst mode has no issue for mf lenses. The C4K 60p and other video modes have issues with mf lenses. I used a generic focal reducer with a 85 mm zf, I set the focal length in the ibis as 55mm. Suppose to be the case after the focal reducer. But the IBIS just has little effect.

But if in 120p photo mode, ibis does not matter much. all of the 75 frames are gone in less than 1 seconds. the final image sequences are stable like on tripod.

To my opinion, OM1 is probably the best deal for hybrids now. Stacked sensor 120p 6k for 3 seconds. Good ergonomics and build quality. Just hope that the MF lenses can be stabilized as well as the native lenses.
