It seems there was a difference in optical quality in your comparison, but If those blue white street light were mercury vapour lamps, the offerings from Leica, Zeiss and Swarovski the detail...

Adhoc,

You might have seen me mention that the Zeiss HT 8x54 appeared soft to some users as it was effective resolution limiting in good light. The Savannah 12x56 would have been designed to the...

Tricky,

Not a straightforward question to answer.

I appreciate that many birdwatchers head for home when the light is low enough to dilate their pupils to about 4mm, so your UV 10x42 ticks that...

Tobias,

Did you ever try the Zeiss HT 8x54? That was a bit of a lemon. A number on the forum found it distinctly soft. Turns out it was effective resolution limiting for those with good eyesight,...

CJ,

As I understand it, the original CIE studies presumed that colour sensitivity was a function of the fovea and was based on a 2 target area. It was later realised that blue sensitivity was under...

Thanks for the info.

Those prices look like 50 less than the RRP for the x42s. I hope they are an improvement for that kind of money.

Hello Linda,

The guys have made good points in questioning whether the 10x42 HD will suite you for weight and magnification. With lens caps it's well over 900g (32oz). That's more than I would want...

One, relatively simple, specification check to can do is see if the linear FoV, manification, eye relief and diameter of the eyepiece all add up.

Welcome to the forum.

Assuming you have the eye relief correctly adjusted it's the FoV @1000m figure that's important. The exit pupil size makes no difference.

The SV is Kowa's 3rd tier range, but not bad for the money. The view is a bit narrow, and it's a bit plasticy, but it is light, and as I remember, the 8x42 I tried was sharp and quite fun to use....
