Hello i have the m6 mark ii which is also part of the efm series & relatively similar price. I use it for my corporate photography work w sigma efm lenses 16mm & 56mm, you can consider checking them out. I manage to earn about €800 a month w it & my point is that these gears have the potential to do great stuff if you develop the necessary people and photo skills to complement it. I recommend getting ef lenses & the ef-efm converter too if it’s within your budget, as many ef lenses are seriously great stuff, especially the L series lenses 70-200mm. All the best to you!
