Interesting review. It looks like the gap is narrowing.

Ilya,
 
Excellent, thank you very much!
 
Please help me out here.
 
Both binoculars being 15x56mm & having 3.7mm exit pupil, what benefit is there with the Vortex having larger diameter (more glass) eyepiece lenses?
 
Thanks

Just a different design.  

In practical terms, it is easier to construct a long eye relief  eyepiece with wide field of view if you have a little more glass to work with.  

Swarovski eyecups recess under the body, so the overall look is very elegant.  However, it puts additional stress on the designer.

Vortex eyecups are visible in the entirety which changes the appearance, but gives the designer a little more room to work with.

Nice review, Koshkin, very thorough and well done.  For many here who may only use a "big eyes for occasional use" or then go to a spotter, another option is the Minox 15x58.
 
Any thoughts here on the Minox, plug here, there is one on the Sample List, for $659.. 
 
Another option, you know it is hard to budget for every optic.
 
I know the Swaro. is hard to match, but wanted to throw this one out there.

I have never spent any serious time with the Minox 15x58, and I do not want to hypothesize too much.

It is a nice binocular by all accounts, but with optics, especially high magnification optics, you usually get what you pay for.

A very nice review with great pics.  Thanks! 
 
I just purchased the Vortex Viper 15x50's and so far am very happy with both the optical and build quality.  I have use these with glasses on and off and both ways work great without any blackouts.
 
These have a little less FOV with 210' @ 1000' feet.  Lighter weight at 27.2 ounces and a close focus of 8.2 feet.
 
I think a couple of the main differences is that the Kaibab is listed as having silver coated prisms although both are phase corrected.  The Kaibab also, I believe, have a different lens configuration (as does the new swarvision?).  Both are using XD or extra low dispersion glass with full multi-coatings.
 
With $1,200.00 versus $600.00 I decided on the Vipers.

Prices and products certainly change over the years.
 
Back in September 2006 I paid $165.00 for my, now discontinued, Pentax 16x60mm PCF WP Porro. Bandito

I checked with Vortex and they tell me that Kaibab has dielectric coatings.  The information on the website is a typo and they will fix it.

Thanks ILya.  I just took back my 15x50's and will receive the Kaibab 15x56's today from Eagle Optics.  Still trying to get to that level of resolution that I'll be happy with.
