Question for NL Pure owners - focus behavior question

[ande7824]

I have a set of 8x42 NL Pure binos and I was wondering if anyone else that has a pair can comoare the behavior of their focus wheel is similar to mine. I'm going to do my best to explain. If it matters my diopter setting is about -0.75.

When I focus on something 100yards away it takes a very small amount of movement of the focus wheel to focus on something about 2500 yards away. The rotation is about 1.5 or 2 "ribs" of the wheel grip knurling to change that focus distance. From there that leave only about 1/4 of a turn of rotation clockwise before I hit the hard stop and can't turn clockwise anymore. Now from my 100 yard focus postion I have about 1 and 1/4 turn counter clockwise to the hard stop.

That 1/4 vs 1 & 1/4 worth of focus wheel turn disparity seems extreme. Is it supposed to be that different? Is anyone else's like that? Or am I being crazy. I have to say the focus sensitivity bothers me more than the total wheel movement.

Thanks in advance!

Are you asking if a large amount of turns on the focus knob with long distance viewing is necessary?

The opposite really. It takes a lot of turning to go from 100yds to close - around 10ft. However it takes less than a 1/10 of a turn to go from 100 to 2500ish yards. Curious if mine has an issue or this is native to the design.

I hardly ever have to adjust at the longer ranges, they have a great depth of field.

That is how all binoculars work.
