I mostly use a hungarian S&B 6x42 and rate it very highly. it sits on my .243 which has been used extensively on roe, fox and hill reds. it's helped take fox at night, roe at last light (very last light!), and hill reds in challenging conditions at reasonably long ranges (175yds to 225yds). I can personally not think of any stalking conditions where I would have wound the mag up or down if the scope had the ability. I enjoy the reasonably small objective lens as it gives great line of sight in terms of cheek weld to the stock and the usage of low mounts.
once my 30-06 is up and running for the hill this summer, there will be a hungarian S&B 10x42 sitting on it for the rest of its life.
my father uses the zeiss you mention, and in the last 10 yrs or so, I don't think the mag has ever moved from 7x, whether fox or hill reds, etc.,,,but I do know he enjoy's the light gathering of the 56mm objective bell, but hates the added height issues, weight, and not fitting into his carry case with a harris bipod fitted....
