I bought My binoculars Steiner Fero D12 at the end of year 2011 on the ebay.The seller had sold him to me, as if in good condition, but as soon as I have had in my hands I realized that the reticle had a line of separation(after open I see one little wire of glue) and dots very visible if you put the image in focus infinity. The lenses had a few scratches and even the internal prisms were a little misty.After 6 months of information, optical schemes Steiner, Steiner Patents, video etc. .. I understand how I should proceed to open the binoculars, hoping not to do too much damage to the chassis of Bayer Makrolon.Over one hour of work, with open tools, I have created a tendinitis to my right arm.I am very pleased with the final result.The Steiner binoculars FERO D12 used German Army has never had a very good judgment, but I rather think that the central sharpness is very good. Only problem , for me , is the optical design of the eyepiece of this old (and first) project Steiner FERO D12 8x30. The prisms are beautiful and very large, with a design different from many other binoculars ...max large at one face and minor dimension at the opposite face. Final result: Very Good !! And Little damage of Makrolon , and perfect Collimation without problems.I'll use for trips to the sea and mountains.Marco Bensi - MMXII
