Re: Oly 8mm f1.8 vs Pana 8mm f3.5

if you're shooting at F/8, you're shooting at F/8.   No light difference.

The sensor pedants will talk about f/8 on FF vs m43, but that obviously doesn't apply here.

That said, if you were using the 8mm on a deep wreck, you might actually want to make use of the f 1.8 option.  Or to capture more in the background beyond the reach of the flash.  It might help on big animals, but only if you can keep the SS fast enough.   Normally DoF considerations outrule.

But I too have thought about making the switch, and saw a really good price offering in wetpixel last year for a used one.   I passed since I've moved to the R5 and I don't think I want to put any more money into my GH4 rig, though the recent Pansonic release does make me consider now that there is finally a newer, higher resolution sensor.

Still, I don't think there is enough incremental benefit to spending money to get a heavier replacement lens, port, and possibly port extension just to get one stop of light in limited applications.  The point of moving to M43, or keeping it now, is for the situations where I want to keep weight down.  Otherwise I have the APS or FF choices.

For someone starting from scratch, easily to justify the 1.8.
