Subject: [Tweeters] 8x and 10x not a big deal?

I picked up the sweetest pair of Pentax 16 X 32s that only have the
stability and depth of field issues. Feather light and way brighter than
I figured they were going to be. They are definitely not good for close
up work but usually a bird that close can be ID'd by eye.

These bins were being cleared for C$59.00. I just about fell over when I
saw how well they worked. I had a pair of 8 X 32s in the same body that
epitomized all the bad things about compact binoculars but not these 16
X 32s.
