No one says that type of distortion isn't in EL binos, but how much you notice it and how much issue it is varies by person because not everyone's own visual distortion is the same. Swarovski didn't screw up and create some monstrosity that makes 100% of the people who use it sick. The rolling ball is the result of a design choice they made to flatten the field and they made that choice because they correctly assumed it wouldn't be an issue for the majority of people. I don't notice rolling ball at all and it's never been an issue, and my ELs get used almost exclusively off a tripod with a pan head. I'll link a lengthy explanation of what it is as well as another Rokslide thread on it. Or you could pop into birdwatching forums to read more about it, since they tend to know 10x as much about binoculars as hunters do.
I am now leaning towards some used swaro el 8.5x 42 or SLC 8x42... The more I research the more I want good glass. I mainly hunt whitetail deer in michigan and ohio. Can anyone comment on the rolling ball effect. id like to get the best bang for my buck but I do not want this so called effect.
