I've been enjoying my G9ii a lot. Have barely touched the OM-1 since I got it.
I have found the G9.2 is a superior macro camera over the OM-1 (because of the sensor)
I think the G9ii is the superior camera over the OM-1 in many aspects. If I could only keep one, I think I'd pick the G9ii. The autofocus is the only thing...if Lumix can release a killer firmware update for the AF to get it to acquire focus as fast as OM-1, it's be game over.
I mainly chose the OM-1 Mark II for my purposes because of the G9II locking you out when emptying a big buffer. Is that still the case?
The strange bugger behavior persists in addition to other factors that kept buyers away. Some are minor - control dials required to change focus mode or burst rate, slow startup time, lack of frame limiter in bursts, painfully slow focus bracketing, mediocre battery life, no flash with electronic shutter, a host of HHHR issues, overgrown file sizes, poor dynamic range at certain burst rates, shutter speeds and ISO's. The diehard Lumix buyers might look past those. Most importantly however, the AF was still lacking (it gives up measuring focus above 6 frames per second).
The G9II never lived up to expectations set by the G9 despite the PDAF hype. Lumix tried drastic discounts, promotions and incentives but it never got off the ground. What else can they offer? The Gh7 at least found a home among creators. It was not innovative like the Gh5 but it makes good use of existing m43 lenses.
