The Sweet Spot

My coffee mug is empty, but I feel like writing, and, I've got some oatmeal to consume...

Regarding the former M6 Mark II and what I feel is the best use case for it:

Travel Photography

When dealing with the unpredictable, you want to have more lenses on you, not less. And, when traveling, you want to travel light. Likewise, everyone wants good quality of special occasions which traveling usually is a more special occasion.

The M6 Mark II makes for an excellent traveling companion. During my business trips the M6 II and the native EF-M lenses do well in luggage, the M6 Mark II does well in image quality, and it's such a fun system to shoot with. Whether you find yourself in the deserts reaching for a wide angle lens, in the cafe reaching for a 22mm or 32mm for food and street photography (with some decent bokeh capability), the 55-200 or 18-150 for creative reach needs, say visiting a local venue or native wildlife, the M system has you covered in terms of the lenses it offers for this sort of use case.

Where the M6 II fails?

Absolute bokeh or image quality on demand. Look to more professional systems with fast zooms (which finding fast primes for the M isn't the problem, the Sigma trio has you covered). Absolute portability. Even though small, lenses equal a bag of some kind, usually. You can backpack with an M for example, but, it lacks weather sealing, and it's footprint can get large for that use case depending how many lenses you drag along. This is where I might kindly suggest one look at the M's brother, the G1X Mark III. For family shooting I recommend going out with just the camera, and one lens extra in tow at most to simplify things. The "duo" comes recommended. But perhaps that's where the G5X Mark II does better than that as it's low profile, doesn't attract attention and has a more versatile single-lens solution.

Tips:

Lenses pairing for given events. For example, Travel, the 11-22 and 32mm f/1.4 are staples. I like to add the 55-200 to make a "trio" where you can cover most creative needs between width of the 11-22, bokeh and macro of the 32, and reach of the 55-200 myself though.

The "duo". That 18-150 when paired with the 22 make for a no bag solution where you only swap the lens when light runs out, or bokeh is desired.
