He offered a nice discount to get rid of his stock and I absolutely could not resist. I understand this is the demilitarised version of the Zeiss/Jena EDF 7x40 (roof prism) which again is the successor of the DF 7x40 (porro prism). Neither Docter nor Zeiss/Jena claimed to have put phase corrected roof prisms in their 7x40 B/GA or EDF 7x40. I however assume that later, EDF roof prism, should be better in this case. And comments on other lists were very positive. I phoned Docter in Eisfeld and the confirmed that they still make them! Soon they will even offer a 10x42 version. Docter binos are not present in many German shops and even their website is miserable. Camera shops typically have Leica and cheap Japanese stuff. Opticians have Zeiss, Steiner and cheap Japanese stuff with German brand names. The EDF 7x40 is quite common on ebay, but I find the final prices a little bit steep, given the fact that you may get heavily used military surplus without warranty. And I am not that keen on reticles, laser filters or radioactive illumination. Briefly I considered a Steiner 7x50, but I have difficulties to track down the different quality levels of coating and sealing, in particular for used gear and with different names for US and German markets. From the subjective built quality I consider them as the binocular equivalent to "Swatch" wrist wratches, excellent performance and value for money if brand new, but sort of unrepairable. Furthermore I thought about the Romanian IOR binos. I hoever could not locate an importer for Germany. US mailorder firms offer them for very decent prices, but with shipping to Germany and VAT it would not have been worth the hassle. Next month I will make a business trip to Bucharest and see whether I can locate them over there. Hans-Peter ========================================= Subject: Romanian IOR From: Fan Tao Regarding the Romanian IOR military style binoculars, they have excellent build quality, similar to the Zeiss Jena 7x40DF(NVA). However, in a direct comparison of the IOR 7x40 vs. the Zeiss Jena DF, I prefer the Zeiss. The field of view and eye relief are about the same (about 60 degrees apparent and 20mm). The image through the IOR is nocticeably yellow whereas the Zeiss is close to neutral. Furthermore, the IOR has (to me) annoying field curvature, that is, the edge of field needs to be refocused to make it clear. The Zeiss also has some field curvature and astigmatism on the field edge but it does not seem as bad. The IOR 10x50 is similar in performance to the IOR 7x40 (plus it is very heavy to hand hold). I do not mean to make the IOR's sound bad, other than the problems mentioned, they are very fine binoculars.

We need more information on this subject. ====================================== Subject: Docter / IOR From: Thomas Press Regarding the recent Binocular List references to the Docter (aka Zeiss/Jena) EDF 7 x 40 and IOR 7 x 40 BGA, I have owned both and found the IOR (at least in my samples) to be the far superior glass, with a wonderfully open and crisp view, and superb build quality. As best as I can tell, the EDF, as a roof prism binocular, is probably better able to hold its collimation in the face of rough treatment, but the view through the EDF was noticeably less sharp, with a much narrower field of view and considerably less depth of field. Both glasses have a yellow tint, although the EDF tint is dramatically more pronounced. Over time, I found the EDF yellow images increasingly annoying, and useful only for moonlight use. Hopefully, Docter Optik has also made some progress on the quality control front as, in my experience, many of the late 80's Zeiss Jena binoculars, both roof and porro, were pretty shoddily built.
