I take a lot of nature photography on mft with my em5m3 and the 75-300 oly. I'm generally happy with the performance but want something faster with more reach.
I also want some nice fast primes for portraiture because I take pics at cons when I can.
Should I go for the 100-400 oly or should I just invest in a snoy/nikon setup (I'm willing to put down a few thousand for this of course). Or would it be better to keep the MFT around for nature with FF for low light/portraiture?
Also note I really enjoy the small form factor of MFT and it's really nice for me on long nature walks. I'm not sure any FF telephotos will come close to the compactness but I'm willing to compromise if the IQ gain is significant.
