I would add that those posting on this thread did so at the request of someone wanting to see images from the IQ3 100. Since it's impossible to judge the quality of the files coming from any digital camera from a few web jpegs, I assume it was simply to see what the back was being used for. But the images are just that and I don't think any of the posters were really looking for a review or critique. And it certainly doesn't reflect on the back itself.
A few seem saturated, each to their own. Sort of remind me of Fuji transparencies, certainly a contrived and artificial saturation but many found it pleasing.
