[Mnbird] Vortex Binoculars

Thanks to every one who reponded to my original post.  I thnk Eric's response below concerning personal fit and feel is good.  If you notice, several reponses talked about weight and hand size and even inter-ocular distance which I can see could be a problem for some people.

 

I personally have a pair of nitrogen filled Nikon Action EX (10 x 50) (from the National Camera Tent Sale), a pair of Olypus Exps I (12 x 50) (from my brother's estate) and two pair of compact Nikon Travelite's that I keep tucked under the seat in each car. All except the compacts seem to have enough light gathering capability to safisfy my aging eyes.  So to this point I am perfectly happy with all of them.  Note that these are all porro-prism binoculars and for the most part open to wide enough inter-ocular distance to fit my face.  I notice that nearly all the Vortex binoculars are roof-prisms.  I didn't see that addressed in any of the posts.

 

What preciptated the original post was a telephone converstaion with my son-in-law in TX.  He is an avid hunter and building a 308 rifle for long distance shooting and wanted to know if I knew anything about Votex Optics.  I tried to Google them but made the same spelling mistake as in the original post  (Vostex rather than Vortex) and came up empty so I turned to MNBird.  I also thought that I might upgrade myself depending on what I learned.

 

I am a mathmatician and retired engineer so I have been following the evaluation posts with some interest.

 

But I realize it is time to cut it off.  Again thanks to all who responded.  And a pair of Vortex are on my Wish List!

 

Pete

In my view personal opinion, in particular my own, is the most crucial element of purchasing binoculars. No pair of binos works equally well for all. Over 40 years I have found that numbers, such as those produced by Cornell, are secondary to how binoculars fit a particular individual. I have repeatedly found that some highly rated pairs do not work for me, even if they do for others. For many years I happily used Celestron ED binoculars, but they were not waterproof and over time developed non-fixable mechanical problems. To me, they provided an unsurpassed apparent depth of field, even if not quite as crisp at the very edge.  I have now switched to the Vortex Viper and am thrilled with the image quality, as a are others I know. Others may find them less impressive because the simple fact is that binoculars do not exist and cannot be tested in a vacuum. The best binoculars are those that work best for you, not those that rank best on any particular test.
