<p>Like some of the others that actually have the camera have said, 8x10 will be easy, although I don't know how big you can safely go. I don't really see it doing poster sized shots unless you're willing to lose some crispness. I've done 8x10 of my LF1 (better sensor, lower megapix) and the detail of the camera was still more than the professional printers could resolve. A3 is probably the biggest I'd feel you can do without much issue.<br>
But how the print will be seen makes a difference too, if it's seen from across the room larger size would still be ok. The picture you hang above a couch isn't going to have casual viewers using a loupe to inspect the quality, people won't be close enough to see the lack of clarity. If you're putting it in the hallway stick to A4 size, above the couch or mantel A3 or A2 isn't too bad.</p>
