If I was to choose a roof prism bino between 500- 700 CND dollars it would have to be I like the Pentax Sp series...
Made in Japan and are made with care..
They sell for around $500-600 CND dollars depending on were you look..
They are a first class bino the only thing I don't like is the warranty that is offered...
Check E-Bay or
www.binoculars.com

Any roof prismdesign and model below $400 CND is 3rd rate junk
usually made in China and the quality control isn't up to par..
Yep they may appear bright but once out in the field
The first thing you will notice that your eyes will get tired quickly because the alignment will be off by miles...
This will happen in the first 15-20 min.......
If your looking for something below $400.00 get porro prism
something like the B&L Discoverer or the something from Stiener...
That is how they keep costs of cheeper roof prism models down cheep labour&they don't spend the time needed to align the roof prism models properly..

Get the best that you can afford and practice viewing from them,it takes alot of skill to find deer and elk hidden in their own naturalenvironment
when glassing from hundreds and hundreds of yards away...

I know a couple of people who follow the first rule, buy the best of the best ,but don't spend the necessary time to practice.
And go home disapointed time in and out cause they can't see game through their binos..
