I'm not really up with instant films. I've never used them and up until now I've never cared. But there is an allure which has gotten a hold of me and I feel the need to look into this format - and I'm thinking of using it professionally if I like it. So what I'm after is a camera that takes Fuji Instax film, either Mini or Wide, but preferably Wide. Like an old Hasselblad ad said, "Bigger is better. To a point." At the moment, I'll be happy with a cheap Fuji camera just to get the feel of the format. Eventually, if I like the way things go, I'd like something more professional. Something with good lenses that lets me manually set aperture, shutter speed and focus. So what would you recommend? Can you use a Hasselblad 500 with Instax film? What about a TLR? Or a 645 system like a Pentax or Mamiya? There are Polaroid backs, sure. But the Internet does not seem to know of Instax backs. I have a Lomography Belair and you can buy an Instax back for that system. So that's cool, but it's not quite as flexible as a MF SLR.
