Not as nice as sx-70. The instax cameras aren't quite as good, fixed focus, forced flash point&shoot things. They can be good for some things but I don't really like them so much as 600 film/sx-70 cameras. I don't know what your friend wants as far as images. This is all my experience with the Instax 100/200 larger format not the minis.
Here's my pictures from the instax 100/200 camera (The 100 camera broke, not sure why, wouldn't turn on again) I basically only used it for sunset photos which came out nice but most other things it doesn't look so nice IMO.
