Thank you Canip for the test.

It reminds me of my experience with a good Canon 8x25 IS.

Generally, false colour is more apparent in the various Canons with the IS on.
Star images are also less good...

Thank you for the very fine test.

One barrel of my sample of the VisionKing 5x25 is considerably worse than the Kowa 10x42 you tested.

Is the use of molded optical elements one of the reasons for...

The problem is that most people would, I think, not understand the difference between conditional alignment and collimation, even if quite handy with tools.

So, if a binocular can be made to work...

Thanks Richard,

I watched the telescope repair and the other repairs.

A heavy scope for the aperture, but it seems to be a fairly long focal length, maybe f/8, so might give good images.

I missed...

Hi Rico,
Welcome.

What do you mean by 10x35 equivalent?

I have a Russian 30x50, which has excellent resolution, as good as the Zeiss 20x60S.
But the 30x50 has poor coatings and ordinary mirrors.
It...

It is rather sad to see a firm like Kowa advertising wide field binoculars if they are not wide field.

Also the reports do not indicate high quality.
I suspect a lot of sample variation also.

Reading the official Nikon literature for the Noct 58mm f/0.95 is interesting.

It is indeed a magnificent lens.

But Nikon claim only Nikon could make a lens of this quality.

I don't have a Swarovski 10x42 to compare, but I think that the Canon 10x42L IS would show more detail with the stabiliser on than any non stabilised binocular hand held.

Hi Andy,

The 58mm f/0.95 Noct lens at 6,000 is in some ways silly, although probably extraordinarily good.

58mm lenses were produced to clear the mirror when changing from rangefinder full frame to SLRs,...

Hi Scarlet,
2 to 3 hours before sunset could be very bright, but you indicate dimming.

Your pupils may be 3mm in that light. It really is difficult to know.
So a 12x36 and 10x30 binocular.

With unaided eyes it is fairly easy to identify some aircraft at 35,000ft height from the contrails.
