Frank,..i am happy too,after a week the ZEN impresses me over and over..
The first couple of days i took them birding in the field,I was really amazed,and i let go many a "wwwow","OHMAN" and the likes...I was quite impressed with long range detail..I bird a small wetland area,about the size of 1 or 2 average city blocks,usually i can identify every Duck in that range ,But not with the clarity i experienced using the ZEN...I dont know if i have a Cherry,or all specimens average this sharp,but i have no doubt they ARE sharper than the NIKON SE 8x32 .
The Coatings are still puzzling me a little...At first glance,they seem to be NOT as nice as any of the Good binos i have owned..Pentax ED coatings are clearly better,and work better in controlling glare,also they offer a bit more contrast,and similar color saturation. the Nikon LXL ,has better contrast due to better coatings,and brutal color saturation(a bit too brutal,the way it bleeds in the form of CA),but none of the mentioned models matches the ZEN resolution .
I must mention that although some glare interfered with the image in some situations,The large exit pupil was very forgiving allowing the eye to move around the glare and still achieve a good quality observation.
(This Problem with glare i found only to annoy me in one extreme situation,when deliberately pushing the view to the most oblique of angles in relation to the sun,at the very midday and in hazy conditions..observation hell namely)
The ZEN has also a Wider FOV,than most 8x32/8x42 and quite Flat.Edge resolution is on Par with the mentioned models
The ZEN are a little bit like the 820# on Asteroids...They are a bit sharper,and bring even more detail than the 820 ,even with the extra .5X..Better ER,and a Great FOV..Also Depth of Focus is remarkable,Or so i am noticing..In this regard the Focus action seems more than adequate ,because only small adjustments are needed for most distances...truly most of the focuser mechanism range is from 10 to 5 feet.Focused at infinity ,One quarter to half turn goes a LOOOOONG way.Perfect for birding.
Very good too for Night Sky observation.My pair Shows No astigmatism or Coma at all(pin point stars with no diffraction spikes in any direction),although looking at the brightest street light,one of the barrels shows some ghosting in the form of (very)faint crossed wide strikes.The other Barrel shows a perfect diffusion of the light in all directions .This only shows when looking directly at bright street lights
.Pity,because i love to look at bright street light through binoculars!!..
CA is not present in the center ,and only so little of the faintest type can be detected in the outer edge,perhaps starting at 60%,very faint ,and almost unnoticeable and increasing a little towards the field stop,but always staying super low. The Pentax ED has a bit better control over CA,and is almost free of it,all the way up to the 75/80% of the FOV.But very close performance in that regard.
I dont know if ED glass offers this advantage only in suppressing CA or also increases resolution when used in the right optical design;The ZEN is an overall superb design.
And,i am really enjoying the Ergonomics of Open bridge configuration.
it really offers many advantages in the field,..Is more comfy to grip,and distributes the Weight in an amazing way...The binoculars feel WAY lighter than they are!!!!
As i said,it feels like the Audubon 820,in the sense that covers all the needs,and ,gosh,Do they get the Job done!!
And like the Audubon,their value ,easy view and amazing resolution,clearly worth any compromise in size or weight...
I am really liking them...
