APSC crop is similar to using an MC14 in effect, but with 26Mpix.Just note that the OM 50-200/2.8 is an internal zoom, and a bit lighter than the Sony. Of course, putting the Sony 100-400 on one of their high resolution bodies allows for significant cropping, but in that case the equivalent aperture becomes much smaller.Both my MFT and FE kits are “irreplaceable” through specific choices. Matching my walk around FE kit would cost the same as I paid for the FE body plus lens, with lower resolution and DR for a kit weight of 1.35kg MFT and 1.00kg FE. The MFT lens has a small amount more light gathering but a much shorter FL range.I can't be the only person whose m4/3s kit is irreplaceable. No other manufacturer produces a camera and lens combination that meets my criteria of performance , price and weight.
Matching my GM1 or OM5 kits is not possible in FF in terms of weight or cost. The OM1 is the cheapest fast readout sensor body with subject recognition and smaller tele lenses available. However, it’s readout speed is much less than FF flagships and it’s AF system is not class leading - still the OM1 is for me.
MFT tele lenses can be expensive - for example the new OM 50-200/2.8 is £2,999 and the Sony 100-400 GM is £2,149. The GM gathers more light at the wide end and can be mounted on much higher resolution bodies. I bought a used 300/4 on weight grounds instead of a discounted 200-600mm G. The used MFT lens was 25% more expensive than the new FE one, but much lighter.
So, for any individual buyer, which is best depends on uses and priorities. There is no inevitability of MFT being lighter, cheaper and better than FF. Being a dual mount user of the two mounts with the largest selection of bodies and lenses, and the largest inventories of used kit, is a plus for me.
You will note that in my first post, I celebrated OP’s happiness with his kit, something that I share. I’m pleased that attempts to start a fight with other system users haven’t sparked the usual car crash, but there is still time before the thread maxes out.

Once I use a shoulder strap screwed into the foot, weight comes down to how long I can point the lens in the right direction which is fine with the GM. I need the Sony grip extension on the A7CR but the body is still some gm lighter than an OM1. The big difference is the stacked sensor.
I like internal zooms, but that’s a lot extra to pay to get one.
In the end, it all depends on specifics. In this case, my point was that MFT can be a lot more expensive. The same is true for primes that gather a lot of light - the 17/1.2 is currently £999 and the Viltrox 35/1.2 in FE £869, although I paid £770 launch price for mine.
The LAB is a whopper because it gathers so much more light and provides more subject isolation than the OM lens. It is optically excellent, with very little LoCA and only just enough SA to give decent background bokeh. You can get a Sigma 35/2 for £579, although I paid less on discount before Sigma realised how competitive the i-series are. Despite the heavy use of metal and all the controls, the Sigma is lighter than the MFT lens and performs really well at f2.2.
Now the 40-150/2.8 happened to be discounted the day I picked up the GM. I was planning on buying a used 35-100/2.8 but the 40-150mm swayed me. I’ve never regretted it, and it goes head-to-head with the GM at 150/300mm until sensor resolution starts to matter. Internal zoom and focus is great.
Resolution and DR matter more to me, but I guess I’d get an A9iii and A1ii if money and storage space were irrelevant. Pretty happy with OM5, OM1 and A7CR.I do hope the next OM flagship can hit the 1/200s mark of the Nikon cameras, and drop the mechanical shutter altogether. I am torn, however, between getting a 25-33mp sensor at 1/200s or a 20mp global shutter. Because a global shutter eliminates the need for high speed sync.
I’m more likely to buy an OM1 ii as a mk i upgrade or add an OM3, whichever is cheaper used in a year or so.And I hope that they are working on a next generation OM-1. Update the sensor, improve the AF. And fix some of their weak UI design. I would easily put up over $3000 for something like that.
That all makes sense.If they put out a camera like that, then I would also be willing to buy a 400mm f/2.8 lens (if they could keep the weight in line with similar FF lenses). Because I photograph a lot of small birds, and even at 500mm I have to crop to 3072x2048. Luckily, we have software that supports such heavy cropping.
Landscape is my thing.
