Conquest 10x42 HD 116m at 1000m measured on stars.
There are quite a lot of older Porro 10x50s that are much wider.
There is a similar Russian EWA but the one I have is poor mechanically. Shoddy build quality.
I consider most modern binocular fields to be pathetic.
100 m for the 10x42 according to the 2003 catalogue.(I haven't been able to find out the field of view of the 10x40 or 10x42 Bausch & Lomb Elites.)
I should have been more clear. The vast majority of hunters that come into our camps wear a Swaro of some sort, then come the Nikon's, Zeiss, etc.

Dear all,
I will try to address some things that were discussed before.
* Henry, the Leica/Kern 8x30 with relatively low transmission for its day of birth, is indeed equipped with laser filters, yielding a rather low transmission for a porro from the year 2000.
* To all others mentioned.
I have investigated the phase correction problem for roof prisms a little further and I found the following:
Dr. Joos published his paper about :"Die Bildverschlechterung durch Dachprisman und ihre Behebung" in a 7-page paper in German in 1943 (I wrote 1941, but that was wrong). The paper describes in detail the cause of the phase problems. He also remarks, and I quote: "Die von Herrn Werkmeister Wendland gemachte Beobachtung, dass durch Versilberung der Fläche ein wesentliche Verbesserung zu erzielen ist, gab den Anlass, der Ursache dieser Bildverschlechterung nachzugehen.....
So the roof prism problem was recognised and a possible solution was reached from the "working class" coworkers in the Zeiss plant. It would take until 1988 until Zeiss implemented phase correction coatings in its roof prism binoculars and other producers followed quickly.

My CZJ 10x50 Dekarem (porro) FOV 128m@ 100m.Bought February 1975.
Eye relief is only 9mm though.

It just occurred to me that this re-issue of the Trinovids should result in a new supply of spare parts at Leica that ought to fit the originals (possibly including some interchangeable eyepiece and prism parts that might fit the old 7x42 and 8x32). The biggest problem with the old ones was certainly the prism. It might now be possible to have Leica refurbish originals with new phase corrected Uppendahls. Since eventually the silver mirror coatings in the old ones will tarnish, rendering them optically useless, a dielectric coated replacement would also greatly increase the effective lifespan of the instrument.
Good luck with that, at least at Leica USA. It's Leica, not Swarovski service you're dealing with.......
I've often wondered whether manufacturing replacement lenses and/or prisms for classic older binoculars would be a viable business proposition. There must be thousands of old 10x40 Dialyts (for instance) out there and although some of their current owners are probably still happy with them, a good number could well be willing to pay for ED glass lenses and dielectric prisms to be retrofitted into them.
Every [smart] brand will start making a "commemorative edition" or a "limited edition" or an "anniversary edition" of an existing product once they realize they can no longer improve it or make a better product. It is a well-established marketing technique. Winchester markets some kind of "anniversary edition" of their Model 94 rifle every 2 or 3 year Leica is similar.. They don't know how to make any meaningful improvements in their existing products so they make red editions, Japan edition or Zagato editions
