Vkalia, you are aboslutely right, there is clearly some improvement in the Pentax over the Monach. At early morning poor light they were similar, but in good light you can tell. I would always pick the Pentax in a blind test. But the difference, over 300 in price, is not a quantum leap. If you cannot ID the bird with one, you can't ID it with the other one.
Happy birding, forget the binoculars, send me some birds. Twitched a Scissortailed Flycatcher this morning. So, one lifer for the new Pentax, 100 or so for the Monarch.
PS, I did compare a Bushnell Legend 8x32...why did they discontinue?...and the pentax, and I liked the 8x better. Same clarity but of course the 8x was all around smoother and forgiving of any faults I might see. As is typical of 8x.
Bottom line> I do not really need another pair.
