Shane Posted June 1, 2021 Share Posted June 1, 2021 I know what E and MRC represent but does anyone know what ES represents on the B+W filters? Thanks Link to comment
dabateman Posted June 2, 2021 Share Posted June 2, 2021 Interesting I am seeing both E and NC to mean single coating on both sides.MRC is multi resistant coating on both sides.MC is multi coating on both sides. EW is extra wide XS is extra slim I see some sellers using ES, when they mean XS for extra slim. That could be it. Yes could be a regional thing. The European links are using ES for extra slim and the USA sellers are using XS. I see that with Amazon. Exact same filter is XS in USA but ES in European Amazon stores. Link to comment
Shane Posted June 2, 2021 Author Share Posted June 2, 2021 I thought that ES could mean Extra Slim but a google image search revealed quite a few B+W filters imprinted with ES on the filter frame that don't appear to have a thin filter frame. I also couldn't find any mention of ES in several of the old and new B+W catalogues. Link to comment
Alaun Posted June 7, 2021 Share Posted June 7, 2021 The ES is always next to the thread size, so it could mean Einschraubgewinde. Link to comment
Andy Perrin Posted June 7, 2021 Share Posted June 7, 2021 What about RF for Relaxed Fit? "Radio Frequency" Link to comment
Shane Posted June 7, 2021 Author Share Posted June 7, 2021 Actually I did find this...."E, ES European standard male threads 0.75mm...E, ES after the size"..... but it is somewhat contradicted by this....."B+W E and ES series...vintage non-slim 5mm thickness frames up to 62mm... 6mm thickness frames 67 > 82mm" Link to comment
Andrea B. Posted June 11, 2021 Share Posted June 11, 2021 Perhaps writing to B+W (Schneider Kreuznach) would be helpful? https://schneiderkreuznach.com/en/company/contact/contact-form Link to comment
Shane Posted June 11, 2021 Author Share Posted June 11, 2021 Perhaps writing to B+W (Schneider Kreuznach) would be helpful? https://schneiderkre...ct/contact-form to be honest, if someone knew the answer that would be great, but that is as far as it goes. Link to comment
bobfriedman Posted June 13, 2021 Share Posted June 13, 2021 Good question... and I have seen this designation.. the comment above is accurate, E stands for "Einschraub" or screw-in, as A stands for "Aufsteck" aka push-on. But I will search for ES Heliopan uses ES quite frequently and it just might be short for EinSchraub. for example, 52mm (ES52) SH-PMC I just found this in a forum somewhere, "E" is the german abbreviation for "Einschraubgewinde" = screw in thread. "ES" is the german abbreviation for "Einschraubgewinde Steil(e Gewindesteigung)" = screw in thread with steeper thread pitch than normal at the same thread diameter. "E" or "ES" are in-house specifications at B&W only. Link to comment
