For Papilio 8.5x21 in Medium & Compact Binoculars
Recommended
Yes
Price
0$
Pros
  • close focus
Cons
  • not waterproof
I have the 6.5x21 model. In addition to uses listed above, they are great for reading small print. Since they are reverse porro, they also allow following the erratic flight of insects.

For TSN-664 Prominar ED Lens in Compact Spotting Scopes
Recommended
Yes
Price
0$
Pros
  • optical quality, focusing, size, weight
Cons
  • Screw on aperture lens cover
This is an excellent spotting scope for the field. The spotting time of this scope is amazing. Again and again, I am amazed at how quickly I can align and focus this scope on a bird in flight or on the ground.

The quality of the body and the eyepiece are excellent.

The one thing that I find a little frustrating is the time it takes to unscrew the aperture lens cap. A quicker snap-on version would be quicker.

For Audubon 8.5x44mm ED in Large Binoculars
Recommended
Yes
Price
0$
Pros
  • Brightness, sharpness, color rendition, feel of armor
Cons
  • Eye cups, diopter, size
Like many before me, I love the views through the Swift Audubon EDs. However, the negative aspects of the eye cups and diopter have bothered me since I have purchased the pair.

At last, I think I have figured how to live with the eye cups. Yes, the twist up eye cups do move on you. Locking positions would have been better. Now what I do is adjust the twist up distance as I look through them, first one eye, then the other. It really is not so bad, since I find I want different twist up differences depending upon which angle I am holding the binoculars--as well as whether the binoculars rest upon the bones of my brow or the eye sockets of my face.

So there you have it. I have learned to live with one of the negatives of these amazing binoculars.

As for the diopter that moves--it must be the binocular elf playing tricks on me. I have found the way to live with it is to memorize my diopter setting and check it frequently. A little pain, but doable.
