I was in Cabela's recently and they had the Cronus UHD G2 10x42 and the Midas UHD G2 10x42. I have been curious about the Cronus as well due to eye relief, other specs, and potential to punch above their price point, so I did a small head-to-head in the store.
I found that the Cronus had sever rolling ball effect while panning in the store (couple hundred yards) the Midas UHD was much more comfortable to look through and left me much more impressed. I don't care how good the resolution in the center of the image is, the Cronus were unusable for me.
My conclusion is that if I was looking into Vortex diamondbacks, I would get the Midas instead. If I was looking into the Cronus, I would probably get the Vortex Vipers instead. I could never live with the rolling ball on the Cronus. I was dizzy inside of 15 seconds.
