SA205 8x42 ED Flat-field Binocular
Very Nice Scope
Got this while on sale as it had good reviews and was the lowest cost scope with ED glass I could find. The eyepiece works great- the screw out eye cup is very nice for both looking through and for digiscoping. The dual focus knobs are nice. I compared this with a Bushnell Skymaster that I had previously been using and this scope was noticeably brighter. That's probably the 80mm dimension at work. Just by eyeballing it, I couldn't tell any difference in sharpness. Both scopes looked pretty sharp. I couldn't tell any real difference in chromatic aberration between them either, but I didn't do a side by side photo comparison in difficult lighting to really compare.
