There seems to be alot of glowing reviews around for Nikon binoculars, my experience with them has not been all that positive.
I bought a pair of waterproof Nikon 8x23 in 1995 for around $500, quite a hefty investment for me at the time. I quite enjoyed them at first, but they never seemed to be "crystal clear", I just sort of accepted this. They got a fair bit of use until 1997 when a friend of mine who is a doctor of ornithology (an expert binocular user) took a look through them and said they were out of alignment. They got put on the shelf and I had every intent on sending them into Nikon for warranty repair or replacement. I finally got around to it earlier this year (yes 10 years later). Nikon binoculars have a 25 year warranty so it was never really pressing for me to send them in. I sent them to Nikon and just last week received an estimate of $165 for repair!! So much for the 25 year warranty. This model was no more than 15 years old but they insisted that if I didn't return the binoculars with the original receipt that I could not make a warranty claim. Who keeps their receipts for 25 years? certainly not me. I sent them an email stating what was obvious to me, that because they have a 25 year warranty, and this model has been manufactured for no more than 15 years, that every single bino of this model ever manufactured was still covered under warranty. After much ado they agreed not to charge me, but only because they required adjustment and not repair or replacement. I had similar warranty/repair problems with a fist generation Nikon digital camera I purchased in 1997.
My advice would be to buy a cheap pair of binoculars until you can afford to drop 1000+ on a pair of Leica, Zeiss, or Swarovski's. I will be be taking the leap and buying a pair of $2000 Leica 10x42 Ultravids next month!!
I have a $50 pair of 10x25 Bushnell H2O's, they are compact, waterproof, very clear, and because they are so cheap I don't have to worry about losing or damaging them. I also have a pair of Bushnell 7x50's binos and a Bushnell Spacemaster spotting scope, both also excelent, and reasonably priced.
If you do buy Nikon's, make sure you fill out your warranty card and more importantly keep your receipt !!
