A little considerati in regarding Swarovski quality control; some months ago, i have tried another BTX 85 for a brief comparison with my BTX 85. I have noticed that the other BTX showed a drop in sharpness starting from 30-40 % of the right half of the FOV. My BTX is perfect in the entire FOV.
The owner of the BTX have shipped the spotting scope to Swarovski, describing the situation clearly, but the BTX have returned with the same problem. In fact, for Swarovski technicians, the performance of the spotting scope was normal.
Remember to try in depth every optical instruments before buying it, because what is "normal" for the manufacturer, could not be normal for you.
Did you try both of the objective lens on the same BTX module?
