Olympus DPS1 10x50's Question

[Hobbes]

Does anyone know if Olympus DPS1 10x50's have BAK-4 prisms. I've been looking on the Olympus website but cannot find any info.

I'd be very wary of that answer. Chinese BaK7 is essentially the same specification glass as Schott BaK4 (international standard designation code 569561). Given that most budget Chinese binoculars use either BK7 (sometimes called K9) or Chinese BaK4 (552634), equivalent to Schott PSK3 (552635), a much cheaper glass, I would be surprised (but would welcome correction), if the "BaK7" in the answer was not actually BK7.

Thanks Steve

I had pretty much decided that they were not the Bins for me.

I tried a pair of Helios Naturesport recently and loved the feel of them so those will probably be my choice.
