Steve,

You are right, appreciation would have been a better word in this context.

What happens in the eye (and brain) is certainly important, but probably the biggest consideration here is how the...

Andy,

There was a lot to like about the Kowas I saw at Birdfair, but I was put off but the CA levels in the 8x and 10x samples at the show. I haven't had a chance to check if that's been sorted out...

I'm not sure it's quite as widely understood as Milo thinks, but he's right of course.

Tom,

Tom,

Unfortunately I don't have the ability to do superscript on this keyboard, but I meant, 'to the power of', and probably should have used E instead of ^. In normal decimals it was between 1 and...

SP,

The available light can be heavily blue shifted when it's "very dull/cloudy/rainy conditions towards sunset and beyond" and the binocular's transmission at shorter wavelengths becomes...

Seldom Perched,

While the twilight factor has passed into legend it seems strange that it is so widely misunderstood.

Alexandr,

Thank you for your thoughts on the 10x50.

Henry,

Keep in mind that the ISO (and I suspect Mil-spec) resolulition standards for 7x50 binoculars are pretty lax. For a 'high quality' 7x50 is just <8.5", or 428/D.The 'general purpose' standard...

Paul,

I think I remember the single hinge Verano. The DBA VHD+ would be a significant improvement.

Nikon have the Monarch 7 and Monarch HG priced either side of the VHD. The Hawke EDX is certainly...

prm,

With ED glass and improved coatings the DBA VHD+ will have a bit less colour fringing (CA), and might appear a little brighter and sharper, but I couldn't say how noticable it would be to your...

Alexandr

I don't know if it helps, but the older Meostar models had something of a reputation for having a rather yellow colour balance. From about 2013 there was a notable improvement in colour...
