Spotting scope with 60mm objective lens and anti-glare lens coating

What are the differences between a large and small objective lens?

• Larger lens = More detail, better image quality at higher magnifications, larger field of view
• Smaller lens = Smaller, more compact scope, lighter weight, more affordable

But the quality of your spotting scope depends on more than just the size of the objective lens. A large lens does not automatically trump a smaller lens. The quality of the objective lens also depends on the quality of the glass used to make the lens. A small objective lens with high performance glass (such as ED, APO, HD, or Fluorite) can deliver a higher quality image than a large objective lens with standard glass.

The higher the magnification, the more important it is to have a high quality objective lens for sharper image quality and detail. At lower magnifications, a smaller and more affordable objective lens should suit your needs just fine.

The quality of the objective lens can also be improved by special coatings added to the glass. For example, the anti-glare lens coating used on the KillZone scope reduces distortion and focuses the light rays for a crisper, brighter image. Special coatings ensure a quality image in less-than-ideal light conditions. Keep in mind that the use of high performance glass and lens coatings will increase the cost of the spotting scope.
