Dan,

Unfortunately the Sightron is tough to find here and usually expensive. It's close cousin, the Kenko EX OP DHII 8X32 can sometimes be found close to your price limit.

John,

Perhaps we should look at this as two different philosophical viewpoints?

John,

To be pedantic, everything you see, or rather imagine you see, is perception. A product of the senses. The brain's interpretation of a heavily processed and manipulated stream of electrical...

I think it might be useful to step back a moment and consider what brightness actually means. It is a visual perception. It is an individual's personal evaluation of the relative luminosity of a...

Kimmo,

The way the brain acquires an image and presents the information to form a mental picture, does not occur in quite the way most people would imagine. In a fairly wooly sense, for photopic...

It's true that both visual acuity and perceptive skills are pretty variable, and I have no doubt that is reflected in an individuals preferred magnification level for a given situation.
