Time to reduce my crazy collection cameras, which will go and why?

Here are my own recommendation. I prefer Small Camera + FF combo over an compromised APS-C. Since you already have invest in both, I would keep them over your Fuji camera collections: a FF + M43 = Combo made in Heaven

Here are M43 camera I would keep:

• Olympus EPL9: Ultimate small camera that capture the Essence of portable M43
• Olympus PEN-F: just discontinued, it will become a collector's camera that you can sell for profit later down the road. These 2 camera rounds out my M43

I would keep a Single FF camera for these reasons:

• Sony A7 (GenII) with 28-70 + 28/2. Get rid of 35mm f/2.8 (useless)
• A7-II KILLED M43 in lowlight high iso clarity.
• A7-II + FE 28mm F/2.0 = Ultimate LowLight Killer.
• there are NO M43 equivalent of 14mm F/1.0 to match
• You won't get much selling A7-II anyways, so keep it
• Keep a FF camera also prevent future GAS attack. Now that you have a FF camera, you're really care for Canon RP or Nikon Z system. If you sold your Sony, you will be in the yet another GAS attack for a FF mirrorless

So these are the (3) camera that I would keep with (1) honorable mention:

• Panasonic G9: Currently the King of Video due to its superior 4K and superior AF Tracking over Gh5 that struggle to keep focus. G9 is also a king of Action: 60fps + 20fps burst + No Blackout EVF. G9 is better than Olympus Em1X for less money

If you don't need Pen-F for collection, then here are my Minimal 3 that'll cover all my needs:

• 1. Olympus E-PL9 = Small M43 for Traveling
• 1. Panasonic G9 = Big M43 for Action, 4K Video, etc...
• 1. Sony A7-II FF = Lowlight Portraits, landscape dynamic range

I am jealous of your wonderful Toy Collection: so many camera; so little TIME to play with them.
