My contribution to the topic of XF 70-300mm and birds
I've been enjoying Fujifilm XF 70-300mm for a bit less than a year now - it's definitely more than usable. I've been taking it for a walks around the city and here are the results. Even in less than ideal lightning situations it's still ok with X-T5 if you embrace the grain (I'm too lazy to denoise), but it really gives sharp and crisp photos when the light is good. Please excuse my editing, I'm still trying to figure it out.
