I use my Z340 now since 4 weeks - along with my Instax 210 and a couple of old Polaroid cameras (with Impossible) film. Since I shoot Impossible, I've been looking for an alternative, the pro photo (drastically) cost me less - the Z340 offers exactly Photos can with the Instax 210 produces (which modern photos that do not have the typical Polaroid nostalgic look. - I use yet extremely happy, but not compete for other purposes), in terms of quality. Instead, they see the old Polaroids deceptively similar - looks to me almost as if Polaroid output specially trimmed. So as I said - the quality is very good, but not as clinical as deductions from the laboratory. Light artifacts (sometimes easier red-slip, despite the latest firmware - but not really disturbing) belong to me in Polaroids to - that's why I like to shoot Polaroid. Anyone looking for perfection, rather buys a reflex and can develop in the laboratory (which of course would at the Z340 - but who does that when he finds out pretty nostalgic feel good shots from the built-in printer :-)))
The camera is easy to handle, offers many options thanks very much fun in-camera processing and the photos come out so, as I see them happy. I shoot almost daily basis and the fun factor is really very high.
