For Audubon 828 HHS in Large Binoculars

Pros
Cons
The 6/10 was subjective. If I draw an imaginary horizontal diameter across the lens, the upper part was sharp within 90% of the radius. The lower part was sharp to about 75%. Overall I would therefore estimate 80% of what is seen is sharp with 80% referring to the radius.

Yes
Price
280$
Pros
  • Waterproof, Good Resolution in Centre, Precise Focus, Good Eye Relief
Cons
  • Blurring at edges
I am certainly not an expert here. Hope my 2c will be useful.

The only optics I can compare the 828 to is my Swarovski AT80HD spotting scope. Ratings are relative to experience with the scope. 1st rating is binoculars, 2nd rating is scope

Resolution - 7/10 vs 9/10
Portability - 9/10 vs 7/10
Durability - 8/10 vs 9/10
Eye Relief - Tie
Focusing - 6/10 vs 9/10
Sharpness to Edge - 6/10 vs 9.5/10
Lens Covers - 6/10 vs 9/10
Digiscoping Capability - 7/10 vs 9/10

Overall, the 828 is a very capable portable device that appears to be quite rugged. However, as expected, it does not comes close to matching the optical performace of my spotting scope. For a price of US$280, this is a very good value.
