I did a search on Flickr and found a dedicated group for Ferrania Solaris film. As expected, lots of poor scans and/or exposures but a few good scans scattered around. Hard to tell much about the film though since most of the images are reduced in size considerably and who knows what kind of post processing was done. The shots seem to be mostly 200 and 400 Solaris film.
Based on what I've seen on Flickr I will try a few rolls when it comes out just to see. It's nice to have options.
