Hi, I did some research on the Pentax 5,5x lupe. Judging by the specs it seems to be one of the best alternatives for a photographer with glasses - mainly because of itīs big eye relief. The thing is that there are totally contradictory verdicts on a possible distortion problem. Three reviews on the net say there is huge pincushion distortion and two say there is none. Is there a quality control issue with Pentax or whats going on here? Any comments?
