That's the instant I've got and I love it. I shoot a good mixture of Square and Mini and
>>3795887 is correct, shooting mini is awkward! The viewfinder does have a little demarcation which shows what part to use for mini but you're going to waste a few mini exposures while you figure shit out.
Beyond that though I've had nothing but joy with my square glass. It looks good, it performs good, Instax sheets are significantly cheaper than polaroids and in my opinion have better color too.
The 30.5mm lens thread is great since it means you can fit a multitude of filters and adapters, the flash is fine and the gels that come with the camera are a fun little selection if you want to get all arty-farty instead of actually taking a photograph.
It's a perfectly good camera, though maybe the red version there is a little overpriced since you can get the black body bundle for a lot less cash.
Lomo's instax cameras are all actually pretty good to be fair but why don't you take a look at one of the models that shoot WIDE, Instax Wide is fucking brilliant if you're into instant photography.
Square Glass Pros:
>Glass lens>Folding bellows gives you like 90mm effective>Looks good>Feels sturdy enough in my hand>The ability to shoot Square and Mini is actually a huge deal in my opinion>Built-in flash, EV+- and multi-exposure gives it more options than most cheap instantsSquare glass cons:
>Shit viewfinder, especially for mini>Not really an indoors camera, it'll struggle with the exposure in low light so learn when you need to EV+
