I've never, in the USA, had a problem with Nikon service, but there have been changes recently, so who knows? For me, the question is irrelevant because the used prices are so good. In the past year,...

Hi Rico70,

Birders generally agree that larger-than-"necessary" exit pupils are a significant advantage for birding binoculars, and you will find plenty of discussion of this on BirdForum. The...

Agreed on the Swarovski and the Nikon. The ED versions of Nikon Fieldscopes are superb optically, are super durable, and they often sell for surprisingly little (even at "buy now" prices) on eBay in...

When viewing butterflies, it is often the bin that allows the closest approach, not necessarily that which yields the highest magnification, which performs best. Butterflies often land on the ground...

Rico70,

as a general reply to your responses thus far, it doesn't seem to me that you experience motion blur as I and others do. As I noted before, magnifying the image increases both the apparent...

I think there is plenty of agreement that it is possible for 25x to show more detail than 7x in hand-held viewing. We just don't agree that it is a good overall choice for hand-held viewing.

Yes, that's the one, and yes they are heavy, and unfortunately a bit high in CA. Otherwise, great bins with superb eye-relief and close focus in a 10x (esp. against the competition of the day). You...

For most active birding situations, I find 30x wide-angle a much more enjoyable magnification than a 40x wide-angle.

I'm w/Rico70 on one detail. All else being equal, I don't think that it's correct to say a 25x binocular vibrates more than a 7x bin which vibrates more than a 1x bin. The 7x bin simply shows the...

I agree with Joachim, I think your eye is too close. I use the same equipment as you and I have no problems. I wear glasses, so my eye is not very close to the ocular.
