I have Steiner 8X30 and must say they are very good.
Good clear glass. Comfortable. Can glass for 1/2 hour solid without eyestrain.
The auto focus works well.
light weight
They are very waterproof.
Only complaint is the focus adjustment which is too loose, and has to be readjusted evrytime you use them.

My next pair will be Leica 10X42. I' ve used them and beleive it' s worth paying the extra.
The glassing Im doing is mostly 1-2 miles and in alpine terrain.

I' m not keen on spotting scopes as they are hard to use over prolonged periods of time, i.e. only one eye, and a lot of movement.
Also bulky to carry around.
