They are essentially the same as the Stratus EPs. I had a look at some at York Optical in Melbourne, they certainly look the same as the Stratus.
But they are expensive, $265 or $285 ea (I forget which). The Stratus can be had for about $180 ea delievered in under a week from the US (or if you're after a 5mm, I've got one for sale
). I've read rumours that an upgraded version of the Hyperions will be coming out, which will have better coatings than the Stratus or the first Hyperions. I don't know if this is true. The Stratus are fully multi-coated. (It says so on the barrel so it must be true
)
