Great for close range viewing,
Verified Purchase(What is this?)
This review is from: Pentax 8.5x21 Close Focus Papilio Binoculars (Electronics)
For close-up work (ie less than about 25m), these binoculars are superb. They can be used to view plants and insects at your feet with remarkable clarity, and are great for a whole range of close-up viewing. They also have good image quality at medium to longer distances, but the field of view and clarity do not match up to those of high end binoculars at longer distances - probably due to a combination of the small lenses (21's are not going to let much light through after all!) and the magnification of x8.5. I find myself using a different pair for longer distance work, but for close-up viewing and as a general all round binocular, you will be very lucky to find better at the price.
Bear in mind what it says in the description of these binoculars:
"...specifically developed to satisfy user demands for close-range observation of butterflies and other insects"
They do the advertised job extremely well, and are superb up to about 25m, but if you are serious about detail at greater distances you will need a second pair to complement them.
A great buy - I'm really pleased with them.
