What are the cons?

So I’m looking at getting an OM-1 MK-ll. I want to know the cons about it, I see all the glowing reviews on social media and YouTube but I hardly see anyone say what they dislike about it and I know there has to be something.
I plan to mainly shoot photos of birds, landscapes, and the occasional sports event. The sport events will just be my kids events and the local rugby club nothing too serious. The Birds will mostly be waterfowl and wading birds.
