Query: Great for long distance

I read the other reviews before purchasing this product, but I have been delighted with them. Bought them for my husband, basically for whale watching on our Hawaii trips. Really, no focusing required if you are looking into the distance. It's a nice change from the old days of finding the subject then tweaking the lenses and of course by then, the thing is long gone. Does not work for closer objects---a little blurry, but the trade-off is well worth it.
