Interesting that this explanation of optics was from someone at the Research Microscopy division at Zeiss. Their optics do a completely different job from binoculars.
I know optics work in basically the same way but I wonder what the explanation would be from someone in their Sports Optics division.
For sure, that is why Zeiss used SP prisms. I still think AK prisms perform better because I every time I try a binocular with an AK prism I notice it has better contrast, brightness, it is more transparent and it is sharper. The only AK binoculars I know of in 42mm are the Zeiss HT's in 8x42 and 10x42, Razor UHD's in 8x42 and 10x42, FL 8x42 and Maven B.2 in 9x45 and 11x45. There are some AK's in 56mm, like the SLC's and FL's, but they get too big for birding. Sorry Henry.
If maximum brightness is what you are looking for, the Abbe-Koenig prism is the best choice. Why? This system reverses the image without any loss of light.
Exactly, but I don't see it happening now that they are into making their binoculars smaller and lighter. An AK will always be a bigger, longer binocular.
So, I managed to drive by the local pushers nest in order to have a look at the new siblings from big Z: Pictures tell some of the story. Pictured above is the SFL 12x50 next to the Meopta Meostar 12x50. The Meostar is a short, chunky bino, weighing in at 1075 grams with the rubber front...

Just the big 56mm Conquest HDX use AK prisms. The 8x56,10x56 and 15x56. The 42mm and 32mm Conquest HDX use SP prisms. I like a 8x42 with an AK prism because they are lighter, and the only two I know of are the Zeiss HT 8x42 and the Vortex Razor UHD 8x42. The Maven B.2 with an AK only comes in a 9x45 and 11x45 only. The Zeiss HT is lighter than the Razor UHD at 28 oz. but it only has 7.7 degree FOV and the UHD is heavier at 32 oz. but it has a larger 8.0 degree FOV. I have the Razor UHD 8x42, and it is an alpha for 1/2 the costs of the SF or NL.

I took the more relevant point to be the "Business Development" department following the correspondent's name. It wouldn't be easy to reach an actual optical engineer... who wouldn't divulge anything remotely resembling a trade secret anyway.
