A sturdy first buy


from Brooklyn, NY  -  Casual/ Recreational

Though these weren't the pair I set out to buy, I am completely happy with what the sales clerk recommended. A great price for the quality, these binoculars have a great angle of view that makes it easy to track quick-moving birds. The biggest drawback, which isn't uncommon in binoculars is the chromatic aberration, most noticeable on bright days with high-contrast objects. It can make tracking patterning and colors on detailed birds difficult. Even still, I'm happy with my first serious binocular purchase and will surely be using them for years to come.

Questions about this item:

Shopper  I purchased Pentax 8X42 DCF WP (6.5 degree angle of view) from Adorama several years ago. I am looking for another pair. Is the Pentax 8X42 DCF CS (7.5 degree angle of view) the closest match? What is angle of view and would the one degree difference be noticeable?
