Fun with 4/3rds cameras/ Image Thread

That old 4/3rds Panny Leica F1.4 is *better* by a margin than the m43rds Panny Leica F1.4 counterpart. It's much bigger but it is much much better. At F1.4 it's already magical and it's all optically corrected, not software corrections pretty much.

Yep - it's a big lump indeed, but the one Panaleica 4/3 lens that I always wanted and loved.
More so than the Olympus 4/3 lenses like the 7-14/4.0, 14-35/2.0 or even the mighty 150/2.0
Anyway, I should take it out more though - that's for sure.

Question for you 43rd experts ... :)

My 4/3 Panaleica 1.4/50 AF works fine on my Panasonic G9 (Mk I) camera.
However, with my 4/3 Olympus lenses AF is rather jerky, but works otherwise fine on my Olympus E-M1 camera.
BTW same results both with Olympus and Panasonic 4/3-m4/3 adapters.

So what could be the reason for this behaviour ?
Is it because of the Panasonic CDAF protocol not entirely compatible with the Olympus lenses ?
Is it because the Panasonic G9 (Mk 1) lacks PDAF ?
Would a G9 (Mk II) with PDAF improve on this ?

TIA !

Bart,

while I use my Panasonic micro4/3 zoom lenses (45-175mm and 100-400mm), on my bodies Olympus E-M1X and Olympus E-M1 Mk1, AF is always "jerky", if you mean by that that you are facing "overshoots" ...
Eventually, correct focus will be obtained, but not as fast as with native Olympus lenses.
Why such annoying behaviour, I have no clue, but I have learned to live with it...

Have a nice weekend,
Rafael

Thanks, Raf. Actually I'm living with this issue for quite a few years already.
I'm hoping somehow the G9 MkII has the cure ...

You hinted at the reason: the Olympus 4/3rds lenses were not designed with contrast AF in mind while *some* of the Panasonic lenses where (that F1.4 panny leica being one of them). I think Olympus did have 1-3 lenses that they designed also for contrast AF in mind but hose are are. I can’t remember off hand but I think the ”SWD” motored re-releases of the 50-200 and the 14-whatever it was standard zoom, are supposed to respond better to contrast AF.

This is one of those “4/3rds standard” (or also “m43rds standard”) where the “standard” is not as “standard” as one may think :)

That said, in the case of those Olympus Lenses, when used in an Olympus / OM Systems camera with PDAF (at least to the OM-5), it will focus faster/better. I Have not tried an OM-3/OM-1 for this, but it probably still works well. To my surprise the EP7 can’t contrast AF those lenses anymore if I remember correctly, so if I was buying a modern OM Systems camera to use those lenses as a key reason, I would double check first.

The G9ii *may* do better simply for having PDAF but you will have to try to verify.

Thank you, Ricardo. Only my 14-35/2.0 has this SWD (supersonic wave drive) designation, the other two, 7-14/4.0 and 150/2.0, are 'plain' ED lenses.
Buying a G9 MkII is an option, it surely will be an improvement over the MkI, but it doesn't make much sense if it doesn't overcome that Olympus 4/3-lenses AF jerkiness.
All the best.

I would say try with a G9ii. Verify, since it has PDAF. The focus would probably still not be as smooth as native m43rds particularly in lower light (is what I have seen with em5.3), but it should still be much better.
