Thank you all for your replies.
In the UK we don’t have large chain stores where goods such as a range of binoculars may be seen, like Walmart or Cabelas. There are a couple of places I could visit but each would necessitate an overnight hotel stay. By making this post, I was really hoping to whittle down a field.
However, yesterday I was able to look through a pair of Nikon Travelite EX bins and the eye relief was fine. The ER is given by Nikon as 15.9 mm. I think this may be Prostaff ATB in the US.
I like Opticron’s bins but the HRWP’s ER is 15mm, which may, or may not be, OK. I can only get to see the Opticron range once a month and have to ask the rep to bring the compacts to an ‘events’ day, which will be about a month away, and even then I can only compare them against others in the Opticron line-up. I bought an ex-demo pair of Vega 8x25 bins just over a week ago for £33.35. However the focus wheel needs attention so I am sending them back for repair.
I had not considered the Olympus but I vaguely recall a post saying that they were sharper than the Nikon’s, but I cannot remember where.
I have often been tempted by Vortex, but it seems to me that they only want to sell to the converted. There retail dealerships do not hold any or many items. However, I came across a hunti-shootin-fishin guy who stocks Vortex in Scotland. He has the Vanquish 10x26 RPs at £98.10 with an introductory discount would bring it down to £88.30. That is tempting but I need to research its reviews for quality. The ER is given as 16mm, but is one manufacturer’s ER the same as another’s. I would have to buy this unseen: although returning it would be possible, tracked and insured post is not cheap. But I am sorely tempted.
I am unable to remember the image quality characteristics of a pair of bins when switching from one bin to another, except brightness when I looked briefly through a Swaro, at an RSPB shop, so I should welcome more experience birders, opinions.
