I am seriously considering one of these scopes, I have never had an AO scope before, can anyone tell me:

Is it possible to range find with a 4 - 14 x 32 scope?

Is the depth of field the same on an AO scope as on a non AO scope, assuming they are both set to the same range. So if I set this scope to 30m and just leave it there will it be the same as a non AO scope set at 30m?

Does the longer eye relief increase, decrease or have no effect on the chance of parallax error. It will not always be possible to focus the scope correctly?

Will it be as bright as a cheap Hawk 40mm scope and suitable for lamping?

So many questions I know, thanks for any replies.
