Gijs,

We know they can, but with a suggested price below $300, perhaps a little unexpected?

Thanks for the link, I'd only seen a press releases.

Perhaps not the model we've been waiting for from Meopta, but an interesting price point. Looks like a Terra competitor to me. The interesting...

Thanks Henry,

An interesting line of thought. The profile of the EP is product of combination of the objective cluster and the eyepiece aberrations so the stop position might well contribute to the...

Henry,

Sorry I've been slow to respond, domestic issues, but I've now had a chance to add a little detail.

CJ,

In light of Henry's post I thought I'd better look again more carefully. I tested a 10x42, 8x42 and 7x36 and used a 20mm aperture mask to stop down the objective. The EP of the 10x would reduce...

I've hesitated in trying to come up with an answer because I've read more than once that the exit pupil is not flat, but not known which way it might curve.

I normally measure ER using two two LED...

Yarrelli,

I have tried all those binoculars at various times and your results do not surprise me in the least. As I recall, all present some degree of field curvature. It simply means the focus...

Lee,

Quite an easy one. To guarantee it, the existing ISO criteria would need to be changed from 240/D to 116/D, but that would be prohibitively expensive. In fact it would be sufficient just to...

Henry,

Ed is right, it is the Greek letter gamma. As used here it is the symbol for magnification.

Evios,

Thanks for reporting.

I've not seen the Vixen or the current Eschenbach, but I would mostly agree with your other observations. The exception would be the Terra pocket. It's quite likely...
