Side focus can be easily adjusted from behind the rifle. They are also reported to be tougher, i.e. take abuse better w/o zero shifts.
However, they have a shorter depth of focus which may not be a good thing under somne conditions.
The other thing is that once you find where to set an AO for various ranges, you can preset them easily unlike the side focus/parallax adjustment system. E
Side focus have a shorter depth of focus? Where did you here this? Is there some optical reason for this or is it another actual diamond coating on Leupy lenses sort of thing.
Can't preset Side-Focus to particular ranges? What a bunch of baloney. If you want you can focus them for whatever range and then make a little mark on the dial you can see from the rear, that way you can set the range focus without getting out from behind the rifle. Or better yet you can just reach up and focus it......................................DJ
