>>3916368>Olympus pro lenses are insanely bigI get that, but I think what's enticing about M43 isn't just the compactness of it, but the versatility of it. You can have an EM5 with a tiny power zoom on it that's nearly pocketable. Or, you can slap on a pro lens and a grip and have great sharpness and low light capabilities. As a system it's really attractive.
If I wasn't so in love with my Nikon Z 50mm 1.8 I'd consider selling all my Z stuff for a couple pro primes and a 12-100 f4 and going all in on MFT.
