For higher magnification from greater distance you might try Pentax PAPILIO II 6.5x21. This gives you excellent 3D impression and since you can focus down to 50 cm you can view tiny thinds from a comfort distance. Since we usually lose eyesight AND mobility with age ;-) this could be a solution for some cases.enricosavazzi wrote:Thanks to everybody for your replies (and if anyone has more to add, please do so).
I own one and it is fun to look at bees or ants (especially also for children) but it is "too strong" for let's say watch repair.
I also had some Russion loupe glasses from old days in the 90ies where they sold everything on flea markets. But the eye distance seems to be very crucial, because if not fitted well using a 4x loupe is rather stressing four your eyes with the time.
