I didn't read all the posts but this is it for me. Depth of field. The side focus scopes I have owned were the newer Leupolds, Zeiss and Nikon.
To me the best side focus was the Nikon Buckmaster.......
I have no clue to all the technical reasons just I know what I saw....

That might be one reason why the A.O. is easier to tune than the S.F. Although, I set my 4 1/2-30X50 on 150 last year in the woods and left it. Never noticed a problem.
