    Audubon 8.5 x 44 HR/5 repair by Nicolas Crista

    I first contacted Nicolas Crista about the Audubon 8.5 x 44 HR/5s discussed in this thread. Moving from place to place meant that it finally took till November 2014 for the glasses to be returned to me after repairs and adjustment. He replaced the dented prism covers with unmarked ones. The...

    Despite their outstanding optical qualities, many consider the lack of waterproofing in the Nikon SE porros a factor in their choosing a Nikon roof instead. The SEs may have occasional fogging in very cold climates. It would be interesting to know from long term users of the SE series, the...

There appear to be many useful comments in birdforum about these glasses, including a brief comparison with the Nikon 10x42se by Kimmo, complaints(including mine) but no dedicated review.

    Nikon 10x42 HG: not satisfied

    I stay in Africa. I got a pair of Nikon 10x42 LX (HG)roof prism glasses (older model) from the USA. They have the so-called “no fault warranty” but my impression is that they are used and refurbished. Optics are unmarked and the exterior is as new. I wear glasses and have mild astigmatism...
