Just had a chance to spend half an hour outside a shop with the new Vixen Atera H 12x30 and have to fully confirm my initial view on them (see post #6 above).
If people who consider buying them will first compare them to the Canon 10x30 or 12x36 or any of the new Canons (10x32, 12x32 and 14x32), I am pretty sure the Vixen will not "steal much sales" from Canon. Price wise the Vixen is, depending on the shops, somewhere between the Canon 10x30 and 12x36 on the one hand and the new Canon 10/12/14x32 on the other hand.
Not only is the image dark, tunnel vision prevails and sharpness is less than expected. CA correction is okay, not super. It is kind of difficult to find a comfortable position holding the Atera, with the battery compartment sticking out underneath the bino and the odd shape of the binocular body I never found an easy way to grab and hold.
The IS system did not really produce a stable image; all the Canons, also the older ones, stabilize better in my experience.
The plastic body rattles a bit and leaves a cheap impression (maybe someone will say it looks "trendy", but I am not convinced).
Overall, I think the Atera is a far cry form the Canons in terms of optical and IS performance.
What is better in the Vixen than in the 10x30 or 12x36 Canon: the focusing mechanism is really internal; in the two mentioned Canons, due to the moving objective lenses the tubes are clearly NOT humidity and dust proof; the Vixen (and the new x32 Canons) have a protective glass in front of the objectives. However, Vixen doesn't specifiy whether the Atera is actually dustproof, splashproof or waterproof.
And: the Atera is smaller and 200g lighter than the Canon 10x30, so you could possibly put it in a coat pocket.
