Look, they didn't make fixed-focus instant point-and-shoot cameras about features. It doesn't NEED them. This is the most fun little snapshot camera I have ever had. I have had many cameras--from my first Polaroid 600 to Brownies, Canons (Film and Digital), Minoltas, Mamiyas, and they've got their uses. However, for just capturing the moment at a party or with friends, you cannot beat the Instax Mini 7s.
The film/print format is an oddball--2.5 x 3.25 or roughly credit card size. The lens is a bit wide, so get close! The viewfinder very accurately depicts composition--only slightly noticeable parallax shift.
Forget about the Hello Kitty looking chassis--you can get one in black if that suits you better.
Go ahead and invest in a photo album, because you will be snapping these little gems a lot.
Get one. Have fun!
