I considered the Obie 12x60 but went for the Nikon AE 16x50. Maybe a few less mm of aperture but excellent build quality. Great views and I am already dreaming about 20x80 Obie’s! It is fun reading about peoples’ experiences and preferences.

Here's mine on a relatively inexpensive tripod using the Oberwerk adapter.  Perfect for grab-n-go.

I have one like that! Those are surprisingly well-made and wonderful for daytime. I had a hard time with it for astronomy use so got a pan/tilt head for that. I keep trying to find the holy grail of a tripod I can use for everything, or at least some things. It doesn’t seem to exist.

CN Review of the Oberwerk 12x60 here. Note that this a 6 year old (2013) review. Some things may have changed.

 

For example:

 

Kevin Busarow – December 13, 2017

"The focusers on the LW Series were improved several years ago. They hold focus well even if inward pressure is applied to the eyecups."

 

- Cal

Very interesting (and revealing) article.

 

Never having seen or used either the Oberwerk 12x60s or the Nikon Action Extreme 12x50s... the basis of my statement in post #3 that "The difference in image brightness between 60mm and 50mm objectives is very apparent", was based upon a comparison between my Docter 15x60s (which are 60mm) and my pair of Zeiss 15x50 1Q Pentekarems (which I no longer own).

 

Given that the Oberwerk 12x60s are actually only 51mm... I'm retracting my recommendation for them, and switching my recommendation to the slightly-more expensive waterproof/fog-proof Nikon Action Extreme 12x50s.

 

Ultimately, of course, I think that in optics, you more often than not get what you pay for. Higher quality will always demand (and merit) a higher price.

Can't find any info regarding a field flattener. If you find, DO tell.

Does anyone believe these models are actually any better than the others or that the fields are even moderately free of astigmatism and field curvature?

 

In the Telescope eyepiece world, Baader 31mm Aspheric claims such benefits but to my eye, it doesn't deliver..It might be better than It would be without the Aspheric element(s) but it's not a well corrected eyepiece.

"Keep in mind that it takes 70% the diameter of your field of view to see one half the area of your entire picture. The outer ring of 30% of the diameter contains the other 50% of the area of your entire view. If you have a binocular that produces only a sharp view in the central 50% of the diameter of your fov, then only 25% of the area of your entire picture is clear and sharp.

 

The 12x50 did a little better than the 10x50. I would say it was decent out to 60% from center. But the 10x50 has a 6.5° fov and the 12x50 has a 5.5° fov (manuf. specs). So really both the 10x50 and the 12x50 are producing approx. the same undistorted field of view of about 3.3°. The 8x40 model suppresses this distortion a little more than the others. The lower magnification makes it less apparent."
